A/N: Um... I never got so many reads on a chapter in one day.

Huh.

Anyways, please check out "Crossing the Limit (Undertale)" another fanfiction of mine.

Why is it called that? Erm...

This chapter mentions that.

Note: I want to give my readers my best. My works aren't always on point. Feel free to point out any flaws...so that I can get better.

Stooooop!

- Chapter 3: You've crossed my limit! -

Rage is a powerful thing.

As badly as he wishes to extinguish the feeling, he can't. He can't stop thinking about Sans... and Undyne. He can't get the memory of watching his brother turn into dust before his eyes out of his head. For a moment, he believed something is trying to possess him. He feels his empty eyes burning worse than his throat. Normally when this happens, he would run for the kitchen to splash cool water on his face, but he is unable to move.

Is he really that angry? So angry that he can't even move his attention away from the screens? It is like, his body is frozen.

Normally, Sans would come around if he is present. He would calm him down so easily... but Sans isn't here. He's gone.

He's gone because of that... human.

"You killed them... Sans, Undyne, others... why...? And Sans... he... h-he... I want him back... you.... you..."

His entire body can't endure it anymore. His bones rattle as he feels his anger growing worse. He feels his right side burning. His right socket reveals a glowing orange iris, something he is unaware of. He speaks coldly "You... filthy brother killer."

He stops moving, thinking.

"No... there must be a reason." After he said those words, the iris fades, and his sockets are empty again. "There must be."

Just as his anger disappears... his sadness takes over. He takes a deep breath as he grabs the notebook and binder, tucking it under his arms. He had already phoned Alphys, letting her know that he will join the evacuation. He will go the the True Lab, and he will try to get a better idea on what his brother's notes mean.

Leaving the room, he shuts the door behind him and locks it. He tugs on one side of his brother's jacket. "Don't worry, Sans. I promise... I promise that I will be careful with myself. As for now... I'm going to see Alphys. She can help me understand what this all is. I hope you don't mind..."

He looks out the window. Everything is so empty.

So depressing.

"Nyeh... I can't let this get into me. I never had my limits crossed before... and I'm scared. I'm scared of what would happen if it does..." He sighs. "I'm scared of how it would be. I heard that once a monster has that happen..."

He glances at a photo showing he and Sans standing between Undyne. Undyne is giving Papyrus a rub on the head which seems uncomfortable.

It was.

But now, he misses it.

"Once it is... they... they can't control themselves from... the overwhelming anger. That is why I still have faith. I can't give up on myself and let this hurt me."

Stepping outside, the snow appears depressing. He shuts the house door and moves his way through the snow to head for the Hotland. As much as he dislikes the place, he has no excuses for avoiding it now. At least the lab isn't directly in it... just the border...

After what could be a few hours, he stands in front of the metal door. He reaches for the door to knock, but he freezes, seeing a pile of dust sitting near the entrance. He forgets how to breathe.

Did the human break in?

He jumps at the sound of the door opening, and without second thought, he opens his hand which holds a small orange magic flame. He crushes it in his hand and throws his hand down at the same time.

Thud.

"Y-you're BLUE now, so... you can't move as you want until I let you go, human!" He is rattling. He doesn't want to fight the human.

He shouldn't had planned on coming here.

He hears a small groan.

"P-Papyrus... d-don't hurt me... I-I didn't mean to startle you..."

The skeleton blinks. "Wait..." He relaxes his hand and steps forward.

A yellow short dinosaur-like monster is on the ground. She wears a lab coat and glasses.

Alphys! He got so careless and attacked her! Well, not exactly attack but... she was pressed against the ground from his panic. "Oh, no! I'm sorry!" He reaches down and helps her to her feet.

The scientist fixes her glasses. "N-n-no. I-it's fine. I just st-startled you. That's all." She heads back inside, waving him over. "Th-this way, please."

Papyrus steps inside. Just as he was several steps in the building, the door closes behind him on its own. He looks around, trying to get familiar with his surroundings. "So, um... how long have you been looking into this?"

"Huh?"

"Have you ever done research on things such as... time and space?"

Alphys turns a corner. "Oh, that? Erm... n-not all the time. O-only recently I did a lot m-more because of the e-mail y-your brother sent me about it. H-he said that he wouldn't be able t-to reach me soon... he had a change of pl-plans..."

"Ok. I see..."

They enter an elevator, and Alphys presses a button. "U-um... you might want to h-hold on to something."

As if on cue, red lights flash. An alarm goes off before the elevator shakes and shoots down. Papyrus nearly screams as he holds onto the rails like his life depends on it. In his mind, it does.

It eases down to a slow stop. The doors open, revealing a dark room with hardly any lighting. Alphys takes out a flashlight from her coat pocket and turns it on. She leads the way down the long and dark halls. "Th-this place is where everyone is hiding. S-some areas are restricted for safety reasons.... so try not to explore anything..."

Papyrus nods. He watches her open a door, revealing a room with a few screens and empty tables. This must be where some uneasy work is done. The feeling of the room makes him want to leave, but he can't.

How long has Sans and Undyne known this scientist? He had communicated with her through the computer, and occasionally they would call. He had no idea Sans knew her. Maybe his brother knew her longer than he has.

Oh, Sans...

And Undyne.

It seems they all knew each other.

Alphys seems busy typing things in her computer. "All I have to do is uh... find the tapes. I watched the human since th-they left the ruins... and the bad things the did... um..."

Papyrus takes a seat on a desk. "I don't get it. What could the human possibly want? Do they hate us monsters that bad?"

"I-I think that maybe their parents taught them to hate monsters...?" Alphys guesses. "W-we have a bad reputation in the surface. The humans don't like us... and some monsters don't like them... I can't blame anyone. I... I don't hate humans or anything, but they make me uneasy. This one down here... I-I think they are the few who really hates us..."

Papyrus shakes his head. "They... they are slaughtering us like they know what they are doing. I can't quite fathom how. Alas, the situation is bleak on our end..."

Alphys stops her work to look at the skeleton. Feeling bad for the reaction she got, she quickly apologizes. "U-um... sorry. I guess I shouldn't had said anything."

"No. It's fine. You... knew my brother, and Undyne... so you were a good person to them. Oh... if only I wasn't so careless. Undyne always told me to stay on guard even if I show mercy in a battle. Sans must had realized that weakness, and he pushed me away to save me... and he died..."

Alphys swallows as the monster shakes.

"Undyne wanted to protect us, too... but even she... she's gone. I... Sans... I'm so sorry....!" He covers his face.

Alphys looks around quickly, trying to figure out what to say. The skeleton's cry makes her jump.

"SAAAAAAANS!" Papyrus buries his head into his arms. He sobs heavily, hiccuping occasionally. "UNDYNE....!"

He cries. He can't stop crying. This never happened to him before. He's sad, he's lonely.

He's scared.

His shoulders jerk. His tears are starting to seep heavily in his brother's sleeves. He feels Alphys rubbing his back to support him, but it won't change the loses they share.

"U-um... P-Papyrus... I-it is bad... I know, b-b-but... we have to m-move on..." She is stumbling her words worse this time, because her voice is shaking. She is growing emotional about this herself, but she is trying to stay strong.

"I just don't understand....!" Papyrus sobs.

Alphys swallows. "No one can quite understand either... which is why I am trying my best." She steps back, letting him cry it out as she gathers the notes and takes then to the desk. She begins to look through them, studying them carefully.

30 minutes have passed, and she closes them gently. She glances at the skeleton who is still quietly crying. "Crying won't... help much. I did enough of that before... but it can't revert history...."

Pause.

"Revert?" She looks at the notes again. "Wait a second... these timestamps are real time... Sans died before all this, but how did he know that certain events would... wait... there were research files explaining something related."

Papyrus lifts his head, revealing his fallen tears. He rubs his face as his crying is reduced to sniffling. He watches the reptile move across the room to go through file cabinets.

"These files aren't mine... but they explain events of time being warped in strange ways. The fabric of space itself had been tampered with on rare occasions... some say our dreams have a sense of deja vu..."

Her face darkens in shock.

"Could it be that all of this happened before, and your brother knew? Maybe that's why he stood in your place to face the human... I mean... he never really had interest in capturing anyone before."

Papyrus' sockets widen. That is very true. For Sans to stand before the human was unlike him.

Did... did he really know?

Did this all actually happen before?

Thinking back, Papyrus had horrible nightmares of himself being killed by a blade over and over, and it felt too real.

Pulling himself together, he tries to tell her something that may serve as evidence to this strange thing.

"Sans once told me that he had stopped caring about many things. When I asked him why, he said that he saw no point in doing anything if it was all going to be the same." Papyrus' voice is bitter, like he is putting the pieces of a dark story together. "At first, I thought he was talking about or relationship, so I tried to make sure he stayed happy. But now... if this whole time and space thing is true... if this all happened before, maybe that's why... he became so lazy. He just gave up, did he...?"

Alphys waves her hands in front of her. "Wait. That's just a theory. There could be something else."

"But he knew the exact time to come out when the human approached me. Sans never had good timing..." Papyrus doesn't want to accept his own thoughts. He can already feel himself growing hotter. "I don't want to think about it... it's too hard to understand! I... I just want this to stop! Sans... he didn't deserve to.... Undyne didn't..."

He begins to cry again.

The burning feeling in his neck bones returns. It's worse this time. He can't hold it in anymore.

It's too hot. Too much.

Alphys can't think of what to do. She continues to stroke his back, flinching whenever the skeleton hiccups between his sobs. "Papyrus... p-please... y-you're m-making me very s-sad..." She seems to be trying her best not to cry as well. Tears have already gathered to the corner of her eyes.

"I... I don't want to believe it!" Papyrus sobs. "The human... why do they do this...? They killed everyone, and Sans... he made it sound like it... it keeps happening! Why do the killing so much?! Why would they do this to us like this? Killing us over, and over, and over, and over....!"

Alphys slowly lifts her hand from his back as she steps back. She seems somewhat scared. "Papyrus...?"

"... and over, and over...! And OVER...! And... A-and...! I MISS THEEEEM!" He bawls again for several seconds before he is able to put his words together again. "Over and over... the notes said they did this so many times... countless times... I don't understand... I just don't understand...! I don't want to think it is true... but if it is... Sans... and Undyne...! Over... and over... a-a-aand...!"

He clenches his fists tightly as he lifts his head. Tears fall from his sockets as he looks ahead.

"Why...? Why won't they stop....?! It doesn't make any sense...! I want to know why? Why go as far as.... rrrrrrRRRR!"

Ting!

The strange sound comes from the skeleton's body... from his sockets, actually. Alphys gasps and staggers back at the sight of orange glowing irises now seen in them. Orange light illuminates from the right side... "P-Papyrus...! Y-y-your eyes...!"

"Eyes?" Papyrus freezes. He is confused by what the reptile could mean, but he leans over to look at his reflection from the table. He is frozen as soon as he sees himself staring back... with those eyes. "What is...?"

What happened?! This never happened before!

"M-my eyes... Th-this is...."

He's terrified.

"A-Alphys! What's wrong with my sockets?! What's wrong with them?!"

"C-calm d-down! Panicking is only going to m-make it worse!" The reptile steps back as the skeleton staggers in surprise. The glow of his eyes are brighter now.

Papyrus moves his hand close to his right eye, seeing the glow. "I'm scared..."

Alphys seems lost on what to do, but she doesn't stop. It doesn't take long for her to have a lightbulb moment. She hurries to a bookshelf and pulls out an old binder that had aged over time. She opens it quickly. "These notes... they were written down years ago. This binder is the only thing I could find that had some background on skeletons. It was written in a strange language... so I was never able to decode it. It must had been written by the last royal scientist. His audio files were spoken in a s strange way, too. Looking at a sketch here... I assume it must be about him or something...."

Papyrus walks over to her as he rubs the tears from his glowing eyes. "They won't stop glowing. Does it say how it can?"

"I can't read it." Alphys says nervously. "Maybe if you calm down, it will stop. Sans' eyes can glow like that too, I think... but only on one side. I think I saw it happen when he got really mad at something... then he started saying some nonsense I couldn't understand... it scared me."

Papyrus looks over to the notes, and he nearly forgets how to breathe.

"P-Papyrus? What's wrong?"

"Are you sure you can't read this?"

Alphys nods. "I had been trying to understand for as long as I... wait... you know what this is?"

"Windings." Papyrus almost whispers. "I... I can read this for you if you want."

"You can..." Alphys stares at him in disbelief. "Um... o-okay. What does it say?"

"Um... it looks like a lot of research notes..." He freezes as horror and recognition fills his face for a second. His eyes seem to brighten for a second, responding to his sudden shock.

"Papyrus? Are you alright? Y-you look disturbed about something..."

"Y-yeah. I'm fine. Just... remembering something..." Papyrus leaves her even more confused. "This was written by the last royal scientist... it makes sense. All of this is accurate."

"How do you know?"

"I just do." He speaks bitterly, causing Alphys to step back. He reads it in his mind;

"It appears that the glow in their eyes are linked to their emotions. Sans always has that dim glow that serves as his pupils when he is content or tranquil. Papyrus... nothing is seen... but for some interesting reason... stronger emotions such as sadness and anger triggers a stronger glow.

It seems to expose the nature of their SOULS.

When it begins to glow, it is due to emotional stress, most of the time. Heavy sadness or anger are examples.

When it catches flames... it resembles rage or hatred. Since skeletons can barely change their faces... or they can't do it at all, the glow is a way to express their emotions... I believe.

Papyrus can move his face easier than his brother. Sans has that permanent grin on his face. He's always smiling, even when he is angry. It is impossible to take him seriously because of that.

When he cries he smiles. That makes him look like a lunatic. But... aside that, the glow is rather unsettling. It's not that I see it as a threat, but it can defiantly send a chill down anyone's spine.

Seeing the fire is defiantly a sign of great distress.

The hotter the flame, the more hatred the monster feels... the more relentless they become. If it blazes strongly... then their limits had been crossed.

Limits... meaning their tolerance... and how civilized they will act in battle. Meaning... they can think with a clear mind and fight using strategy.

Enraged, they become destructive like any other enraged monster. They don't think. They just destroy.

How curious. What would happen if the brothers' limits are crossed? Sans is awfully weak, but his brother may serve as a better use.

That orange glow..."

He stares at the notes for a minute longer. He had left Alphys somewhat frightened since he didn't say a word.

After several seconds, Alphys steps forward. "Um... didn't you say you were going to read it?"

"Nevermind. It's nothing." Papyrus sighs.

"But..."

Closing the notebook, Papyrus presses his hands on the desk as he tries to absorb what he just read. He places a hand near his glowing eye.

"This... this is happening to me because I am so upset...?"

Alphys is lost. "Papyrus...?"

"I never knew I was never upset before... or I was. Just not in years..."

The image of Frisk crosses his mind.

"Human... why... must you make me try to push me? If you cross my limits... I'm afraid I won't be able to stop myself..."

Alphys gasps. "Oh, no... crossing the limit? We... we don't want that to happen to any monster. Once it happens they... they just lose their sight on themselves. Y-you can't let that happen to you. St-stay strong... I don't want to see you so v-violent."

Papyrus sighs. The glow in his eyes finally fade. "I... I still have faith in the human. My line has not been crossed yet. Not even close. I refuse to imagine what would happen if it is... which is why I must never lose faith!"

"Th-that's good."

He nods. "Human... please do the right thing when we meet. I... I would hate to hurt you. I would hate for Sans to see me lose myself... so... I will talk to you... and maybe, maybe we can be friends."

Alphys watches him leave the room.

"I know we can."

-OoOoOoOo-

Papyrus laughs lightly. "You came back? Again? How many times do I have to kill you?"

No answer.

Papyrus' eyes slightly widen as the human steps forward, ready to fight again. "I still really want to believe that you can do good, human. I really do. Even the worst people can change... even people like you."

The child walks forward.

"But... you're making it so hard for me to see that... you can change. I can see right through you. You're a... really bad person. But maybe... maybe you can change. At least that was what I kept saying before. However... you get worse. Not only that, you tricked me and killed me in the cruelest way possible, and now I'm angry!"

The monster searches for his words.

"You're the very first person I ever lost faith in. That's sad. I thought the day would never come... but I guess sometimes... people like me are too good for other people." Papyrus watches the child move forward. "You're the first person I ever felt hatred towards. Do you know what this means? Do you have any idea... on what you did? My kindness and forgiveness is what keeps me who I am, but..."

Frisk stops walking. They prepare themselves, taking notice of the monster looking at them angrily.

"alas... it seems you've done it. You did what was once impossible. You pushed someone as kind as me beyond his tolerance. My limits had been crossed, human. I promised myself I wouldn't let this happen... but it did."

*Papyrus is enraged.

Frisk grins.

"Why are you wearing that expression? Are you saying you wanted this? Human, how did you even know about this? No one has told you... unless Sans warned you about it in your past runs?"

*You tell him you pushed Sans over once before.

"How did you... you really are cold..." Papyrus sighs. "I guess I have another reason to stop you. You'll try to do it on Undyne, and maybe even Alphys. You want to see us lose our mind and simply want to... kill you."

Frisk watches him walk forward a bit.

"Human, you crushed my faith I had when you killed me after sparing me. This is all a game to you, is it? Well... you unlocked a new event, I could say. You defiantly crossed me. My brother just wasn't enough for you? Well, perhaps I will be more entertaining for you."

That is not it.

Sans simply didn't last long. Frisk can remember it so clearly.

-OoOoOoOo-

The first time they faced Sans... he was surprisingly calm after all that was done.

What they didn't know was that the monster was seething in rage inside, but he kept it tame to not lose his mindset.

Sans has his hands stuffed in his pocket as usual. He slightly tilts his head, watching the child. "heya. you've been busy, huh? so, i've got a question for ya. do you think even the worst person can change...? that everyone can be a good person, if they just try?"

It dawns on the child that he is speaking Papyrus' beliefs. It seems to make the skeleton remember what happened. They can tell since he appears somewhat angry. Frisk decides to end it here. They take a step forward, which causes Sans to laugh with closed eyes.

"heh heh heh heh... alright. well, here's a better question." Sans opens his eyes, revealing his sockets to be completely dark. "do you wanna have a bad time? 'cause if you take another step forward, you are REALLY not going to like what happens next."

Ignoring the warning, Frisk steps forward again.

Sans sighs. "welp. sorry, old lady. this is why I never make promises."

Frisk draws out their weapon of choice, a real knife. They carefully watch Sans who appears to glance at the window.

"it's a beautiful day outside." Sans says, somewhat pleased. "birds are singing. flowers are blooming... on days like these, kids like you..."

Frisk's mouth partially opens as Sans's glowing "pupils" disappear, making his sockets completely dark and empty. This is when he looks truly intimidating.

He did this before in the past, warning the child to not kill his brother.

The child feels themself in position to battle.

Sans nearly fails to retrain a growl. He speaks surprisingly firm at the same time: "should be burning in HELL."

Frisk steps back. Looks like it is time to dance.

Sans' left eye reveals a blue glowing iris. He opens the palm of his hand, and blue flaming magic engulfs it.

Frisk feels their legs become heavy. A blue light glows from their chest. Their SOUL is BLUE.

Sans throws his hand down, forcing the child to slam to it. Bones shoot out, stabbing through Frisk in many places. As the child stands, their SOUL is normal again.

Sans swings his arm, summoning a wave of bones from the ground and the ceiling flying towards them fast.

Frisk lunges through the small gap, getting scrapped by the tips of the bones. They land harshly on the ground, groaning.

Sans snaps, and a pair of gaster blasters are summoned. He thrusts his hands forward, and they fire.

This is new.

The child dodges both in the nick of time. Many more blasters are fired from many directions. Caught by surprised, they are vaporized, forced to reverse time by a few minutes to revive themself. They return to their last SAVE and head forward to confront Sans again.

The monster snickers. So, he knows he got them.

"heya. you look pretty frustrated about something. i guess i'm pretty good at my job, huh?" Sans begins to perform the same attack. Frisk manages to dodge them for once. "huh. i always wondered why people don't use their most powerful attack first."

That was his most powerful attack? That makes things a lot easier.

"anyways, as i was saying... it's a nice day out." He shrugs. "why not relax and take a load off?"

Frisk decides to check him.

*SANS: 1 ATK. 1 DEF. 1 HP.

*The easiest enemy.

His attacks come in fast. Frisk is forced to jump between gaps and spaces to avoid damage. For some reason, even when they got struck, they feel the pain spreading across them like a virus.

How is he doing that when he can only deal 1 point of damage?

*You feel your sins crawling on your back.

Frisk is slightly afraid of this strange thing. The skeleton is using the child's sins against them as a way to deal more damage. It is like, karma is taking a toll on them.

After being struck again, they die.

They return to their SAVE point and approach Sans again.

"hmm.... that expression... that's the expression of someone who's died twice in a row." He chuckles and winks. "suffice to say, you look really... unsatisfied."

Frisk is defiantly annoyed.

"alright." Sans' pupils disappear this time. He speaks darkly again with a dark tone. "how about we make it a third? ready?"

Once again, he performs the same attack.

Once again, it is dodged enough for the child to live through it.

"here we go."

So... with many attempts... they die at one point...

"hmm.... that expression... that's the expression of someone who's died thrice in a row." He pauses, closing his eyes in thought. He opens them, looking at the child. "... hey, what comes after "thrice", anyway?"

His pupils are gone once more. The anger in his voice is heard.

"wanna help me find out?"

And again...

"hmm.... that expression... that's the expression of someone who's died quice in a row." Sans pauses, looking slightly confused. "quice? frice?"

After pondering, he simply gives up. His eyes turn dark.

"welp, won't have to use it again, anyway."

Yet, again...

"hmm.... that expression... that's the expression of someone who's died five times in a row." He winks, teasing the child. "convenient, huh? that's one for each finger." He closes his eyes. "but soon... you'll need a cool mutant hand to count all your deaths."

Once more...

"hmm.... that expression... that's the expression of someone who's died six times in a row." He winks, teasing the frustrated kid. "that's the number of fingers on a mutant hand."

Frisk frowns.

"but soon... you'll need a mutant hand with even more fingers."

To the point that it gets really annoying...

"hmm.... that expression... that's the expression of someone who's died seven times in a row."

How Sans manages to keep a death count is unbelievable. He teases Frisk more and more with each attempt. This time around, however. he praises the child with a tip.

"hey. that's good. seven's supposed to be a lucky number." With a wink, Sans adds, "who knows, maybe you'll hit the jackpot... and that number will multiply tenfold."

Does it ever end?

"hmm.... that expression... that's the expression of someone who's died eight times in a row." He winks as usual at this point. "that's the number of fingers on a spider. but soon..."

And Sans keeps making fun of them about it.

"hmm.... that expression... that's the expression of someone who's died seven times in a row."

Frisk is confused. Seven? He finally lost count?

Realizing his mistake, he glances to the side before looking at the child with a wink. "... nope, wait, that's defiantly nine. sorry." His apology is false. His eyes darken as he speaks darkly; "or was it ten?"

It dawns on Frisk that he is actually doing this to keep himself from giving in to his rage.

How do they know?

His jokes get more cruel each time they come back.

"hmm.... that expression... that's the expression of someone who's died ten times in a row." He chuckles and winks. "hey, congrats! the big one-oh!"

He's having fun with this.

He looks at them. "let's invite all your friends over for a big shindig. we can have pie, and hotdogs, and..." He pauses, closing his eyes. "hmm... wait. something's not right."

Tired of the skeleton, Frisk has already drawn out their weapon.

Sans' sockets open again, empty and dark. "you don't have any friends."

Maybe he will stop at 10.

Or not. Frisk died again and returns...

"hmm.... that expression... that's the expression of someone who's died eleven times in a row." He winks. "well, give or take. there's a nuance to this stuff. don't think i'll be able to count very well from here."

Frisk was growing tired of the monster counting, anyway. How is Sans able to even tell? It must have something to do with his eye. It glows and stares them down a split second before disappearing.

Sans opens both eyes, having a small idea. "count for me, ok?" They turn dark and empty. "we'll start from 12."

With another failed attempt, Sans simply said;

"let's just get to the point."

After many more failed attempts, they strike him down. But one time wasn't enough. Even after he turned to dust, even after all that took place... they run across a fallen child who promised them something...

... only to want to cause mass destruction again.

And again.

And again.

They want to see what would change at the same time, and so did Frisk. They had forgotten the good memories, now focused on manipulating time over and over again.

At the 99th genocide run, when they defeated Sans, they decided to revert time minutes back to fight him again just for the heck of it. It's not like anything would change...

... right?

Sans appears surprised as the child walks to him again. "... that expression you are wearing..."

Frisk stands before him with a grin filled with malice. They seem to be entertained. It makes Sans somewhat uncomfortable.

"well... i won't grace it with description."

Frisk takes notice of the monster clenching a hand. So he knows they killed him. He just chose to not say anything about it.

He knows. Just what abilities does that monster posses?!

Frisk attacks once again, easily evading all attacks with a grin on their face. They go through the process once more... until they strike him down...

... only to revert time moments back. 2 times in a row isn't enough.

As they approach him, Sans appears rather annoyed from the look in his eyes.

"... that expression on your face..." This time, Sans' eyes turn dark as he growls slightly. "you're really kind of a freak, huh?"

Frisk smirks. They know this will be as easy as before. They just aren't satisfied yet. They'll keep killing this monster as many times as he killed them. It's sort of a... retaliation.

Sans closes his eyes with a sighs. "it's a beautiful day outside. birds are singing. flowers are blooming... on days like these, kids like you..." They open, still dark as before. He does something that catches the child off guard.

He attacks.

Frisk is struck by the shooting bones and is grazed by a wave of it before they could dodge. They dodge the rest of the familiar pattern. Insane! He must had figured out that tricking the child by attacking sooner is a better chance to land a hit.

This is the 99th time Frisk has done the genocide run. Probably the 200th time they fought the skeleton, and Sans is getting tired of seeing them so many times.

"... you get the point." Sans speaks calmly, but there is a hint of anger settled there. He's defiantly at his limit this time. "you just don't know the meaning behind the word, "quit". heh heh heh... kid, I don't like what you are doing here. you're making me really want to do some messed-up stuff. so... do yourself a favor. turn back now, and reset. if you try to keep going - and i feel like you'll keep on anyways - well... you'll learn why we monsters try to steer clear from..."

Frisk is confused. Sans had stopped talking suddenly, like he was about to say something odd.

"...i got this... terrible feeling crawling through me. it feels like fire. if i had lungs, i could probably breathe it out. yep. it's mostly on my neck, and it burns pretty bad. that's from being nervous... or simply from seething rage."

The child seems confused.

"huh? you look confused, oh right. you must be wondering why i don't look angry. well, i am the type of guy who doesn't like getting angry. besides, they say a smile is all someone needs a day. aside that, i can't even frown if i tried. i'm a skeleton, remember?"

Right. He can't exactly... make facial expressions. Sure. He can wink and make expressions with his eyes since he has eyelids or whatever it is, but he is stuck wearing a smile.

How does that go?

"so... do you think i am angry?"

He doesn't sound angry. If he is really enraged, he is doing a good job hiding it.

He chuckles. "well... this whole genocide thing you keep bringing up is getting old. i don't care about whatever reason you have for swinging that blade around. i am too tired. i want to go to sleep. i don't feel like doing much of anything, really. even standing here takes too much effort, because i did that enough times prior. so... what are you doing?"

*You tell him that you want to see something change.

"you want to know if something will change if you keep doing the same thing? that... i can see that reasonable, actually. kids are a curious bunch, but your curiosity... it's dangerous. there's more too it than just a cluster of "what ifs" in your agenda, is there?"

*You tell him that since the war, humans had seen monsters in a negative way.

*you want to see if monsters are actually how humans see them.

"ouch. kinda harsh. humans think we are so brutal? are we too nice for them?"

Frisk watches him carefully.

"so... here is what i am thinking. you're uh... doing some sorta research. you're studying how monsters respond to certain situations. you place a scenario of a human befriending monsters... and a scenario of a human killing them. you compare and contrast. you want to see how closely we resemble your race."

Sans may be lazy, but when it comes to putting puzzles together, he should get the job as a detective. Then again, he would be too lazy to do as much as leave the police station...

He moves his hands in his pockets. "hmm... so... you want to see our behavior in different scenarios to learn more about us? each one of us looks at humans differently from your actions. monsters like Papyrus believe that even the worst can change. Undyne, well... she hated all humans after your little murder game. others saw you as a demon instead of a human. even with those results, you're not satisfied. you want to learn more. you want to see another side of not just me... but all monsters. a side that hasn't been surfaced yet. i think i know what it is. it is the image humans see us as, right?"

The child doesn't answer. Sans seems a bit confused. At the same time, his eyes give away the fact that he is surprised.

"you... you want to see if that is true?"

...

"... is this what you wanted, kid? do humans really think of us that way? do they believe that we monsters are just ferocious beasts wanting to tear any human we come across into shreds in pure bloodlust? that we bare our teeth and claw at anything? is that what you want? because i am warning ya. everyone has their limits. being lazy means i don't bother with it, but now i have a new reason to stop ya, kido."

Frisk takes another step forward.

"you want all monsters to be the stereotypical image that humans see us as, right?"

No answer. They just stare.

"that is why I have to stop ya. i can't let you trigger that in anyone. starting with me isn't wise."

...

"here is a lesson. cross the limit of a human. they act out of it and do something they would had never considered if they were calm... such as taking another life. however, they can stop himself with enough DETERMINATION. however... in a monster's case... it's different. before I explain the differences, allow me to say this."

Frisk listens.

"alright. so during the war, this human did cross the limits of one monster, alright? that monster went on a rampage. it was witnessed, and my guess is that humans kept that event in their books and taught it to their children that all monsters are that way when really... they set that one guy off." Sans seem bothered. "so... you want to set someone on a rampage to witness it for yourself. you want to set me on a rampage."

...

"heh... this is what i am afraid of. you are doing this not because you are bored. it's something much more sickening. if that is what it is then... wow. you're one twisted little demon, aren't you? you really want to see it?"

They step forward.

"i'll ask you one more time; is this what you've wanted all this time? for a race of monsters... you think we were too nice? it was suspicious to you? so... you want to see our so-called "true nature"? to stop hiding our "true selves"? to... show our "true colors"?"

The knife is drawn.

"wow." Sans chuckles. "i honestly don't know what to say to that. looking at the books your kind has... some describes us as ferocious things with the desire to kill every little thing we see. you want us to prove that is true, so you keep coming back to try to set us off... anger us to the point we just can't take it anymore... you want someone to snap."

Frisk smirks. It must be. They are curious... these monsters are too civilized. They must have something in them somewhere that makes them not humane.

Sans shrugs. "i can't blame ya for thinking that way, kid. monsters aren't humans... but humans can be monsters in your book. humans are called monsters when they do terrible things. so... that labels us as feral bloody things... you're something else. so... look. as i was saying... this is a bad idea. you do NOT want this."

Frisk doesn't care one bit. It is clear on their face.

"you want to know? fine. i admit it. i AM at my limits. i'm tired of seeing you again and again, dying by your blade... seeing everyone die again... trust me... oh-ho trust me."

Frisk is left confused. Sans' lets out a long wheeze before chuckling for a few seconds.

What's so funny?

"i don't know what to say. you want to see what will happen when our limits are crossed."

That is true.

"i mean... you somehow brought undyne to break her own limits and she fought you without speaking a single word. she was so serious about killing you, how did you manage to make her push herself to the point she started to melt? kid... i won't say an idea in my mind since you might try it... but she was at the brink of snapping. she would had went mad and attacked you like a shark. heh..."

They want to see every monster break down and lose hope. They want to see them change completely from their tamed personalities. They want to see just how far a monster would go to get rid of something they hate.

*You tell Sans that monsters are not humans, and they will never be one, so why act like one?

"why act like one? so... being civilized is unacceptable to you." Sans says. "you say that we are like a lion catered by a human. tame and friendly. ok. time for a small fact. you know about instincts?"

Frisk nods.

"a lion can still kill."

That's the point.

"instincts lie dormant things happen. if i toss a bone to greater dog... he would abandon his armor just to get a lick. he's a dog. he can't help it. so... in your mind... monsters are monsters. they want to kill whatever they see. they can't help it. now i see... now i do. kid... this is a really, really bad idea."

A bad idea? He keeps saying that. He really doesn't want the kid to find out.

"you're right. we aren't human. so... let me ask you... there is a saying here in the underground. ever head... "crossing the limit"?"

The child shakes their head no.

"really? all the resets and not once? alright. let me summarize it. here is the differences between humans and monsters with a crossed limit. once a monster gets a taste for blood... they won't stop. what i mean is, a human can have the intent to kill... they can control himself since they have DETERMINATION to do it. a monster... once that intent to kill is set... they can't change it. that is unless someone steps in someway or the target changes their perspective by certain actions. aside that, they will stop at nothing until the job is done."

The child seems lost.

"confused? alright. bloodlust is impossible to stop once triggered. DETERMINATION is different. it means you won't give up by all means. it means you have the willpower to stop if you feel the need to. being unable to stop? that is different. you can take the biggest slacker and they can't stop what they can't control. they don't have the same willpower humans do. we just don't. it's why your race defeated us in the war."

So...

"to put it in short... rage is impossible to control on our own. we let our bodies move on our own. we are not willing to stop ourselves. but undyne... she somehow gained DETERMINATION. she was able to use her anger as a power source instead of a destructive one, because she was so willing to stand her ground and stop you. she was luckily not blinded by rage."

That makes sense. Frisk was confused when he mentioned Undyne having her limit crossed, but the mentioned monster was in control of her own actions. Now, it makes sense. She was able to keep a leveled head because of her DETERMINATION.

Sans continues his explanation. "a monster blinded by rage has given up on himself and allowed it to control them. that is why crossing our limits is dangerous. but, uh..."

He studies the child for a moment.

"you remember what we are made out of, right? you humans are... made of mostly water. as you know... we monsters are made of magic. so... here is a rhetorical question. what happens if a monster uses too much magic? maybe it's like a human when they become dehydrated... it is why we try to avoid having our limits crossed in all coats. some monsters are more aggressive than others when enraged."

The thought never really crossed the child's mind. What happens to a monster if they use too much magic? Is that even possible? Their magic has limits?

"just let me give you a fair tip. the nicest people... are the most dangerous... so don't... even... try... it... you know, on certain other monsters..."

His eyes narrow, which is his way of frowning.

"i feel like you don't care about that."

No answer.

"you realize i basically was giving you a long warning through all that talking, right? do you hear me, pal? if you manage to somehow... push me off the edge... which i hate to say is awfully close... well..."

Frisk lunges forward with a swing. The skeleton dodges easily by teleporting feet away.

"a dirty move their, kid." The anger in his voice is how more noticeable. "you're already filthy enough from all of your crimes. yep. you really want to see it. are you that desperate? you keep pushing me and see what happens."

Frisk steps forward.

"i won't give you a bad time." Sans chuckles again. "because i already have ittle patience. i have little mercy left to give... it is burning. everything in me is so close to slipping. i've ran out of time. kid... take my warning seriously. never does anyone want to push a monster off the edge. this is your last and final chance. take it or leave it... because if you keep going, you will really hate what happens next. I WILL give you THE WORST time of your life."

He is defiantly serious.

"so... turn back. because... if you somehow shove me off that edge, you will call out a side of me you never thought i would have. i wouldn't be the same guy you fought times before. i would be well... what humans call a monster. do you really want that? if i start, i can't stop. that is what the research says. you can't tame an enraged monster."

*Sans is shaking with compressed anger.

*He is having a war with himself.

He is uneasy. He looks at the child in a way that reads his pleas to just stop. But... Frisk won't listen.

They want to see him snap. They had wanted to see a monster close to them lose all sight of themselves for a long time now, and this chance will not be passed on.

But... what if it is too risky? They never saw Sans behave so brutally. He can be brutal with words, but actions? The worst he did was a betray kill. Can it be worse?

Sans narrows his eyes. "i am running out of more patience by just looking at you ponder. make your choice carefully, and if we really were friends once... if you really think there is still hope somewhere... don't do this. my brother would still have faith in you, so... a part of me still believes you are in there."

What?

"heya, frisk. buddy? pal? are you in there?" Sans is shaking pretty bad. He seems very uneasy now. It is too clear.

*Sans is afraid of himself.

*You are really trying to cross his limit, are you?

Frisk lunges forward and swings their weapon. Nearly catching Sans' off guard, they miss by an inch. Sans had dodged in the nick of time with his eyes going wide in surprise. The child staggers before standing tall to face the monster to attack again.

Sans tries to keep his voice from shaking. "remember me? it's me... sans. sans the skeleton. remember the old woopie cushion trick?"

Frisk attacks again.

It is dodged.

"y-you are still in there, right? i still have faith in ya, kido. you don't have to do this. please, just do the right thing. papyrus would want that."

The child attacks.

Missed.

"i don't want to do the unthinkable if... if a part of you is still fighting in there. just drop the knife and... and we can move on. start over. i don't want to hurt you like this. It's getting harder to hold it back, you know?"

They attack.

Missed.

*Sans is sweating.

"this terrible feeling is starting to overwhelm me. c'mon. stop this before it's too late. once i start, i won't be able to stop."

Attack.

Missed.

"do you want to go back to the good times, when we were all friends? if you were truly my friend once, you would start over. turn back now, alright? let's all be pals once more and put this behind us."

Frisk is left with two options:

*YES

*NO

The child stares at the skeleton. The monster appears to be holding himself back, studying the kid carefully. Why turn back now? Finally, something new happened. Sans is growing tired of all this, and this is a chance that cannot be past!

So, they take another step forward.

"no...?"

Frisk attacks.

Missed.

"i don't understand you sometimes, kid."

They attack.

Missed.

"so... you say that we were never friends?"

They attack.

Missed.

"what you are saying is... you manipulated us to achieve some sick goal?"

Attack.

Missed.

Sans closes his eyes with a small laugh. "this would break papyrus' heart."

Metaphorically speaking.

"i believe ya. so, we were never friends." He sighs, and a slight growl is heard afterwards. "welp... don't say i didn't warn ya. this is what you asked for, right? ok. fine. your wish is granted, kid." His eyes open. The left one reveals a blue iris that flashes yellow for a second, now caught in flames.

It's in flames now? That's... also new.

"this feeling... i think they call it "hatred". right?" Sans asks. "because this never happened to me before. i didn't even know my eye could do that, but thanks to you... it happened. it seems the flames are a way of saying just how i feel right now."

He laughs again, only it sounds a little forced. There is no hint of joy in it at all.

"then again, it makes it so easy for you to know what expression i would be wearing on my face if i could do it. don't be fooled by this smile, kid. pay attention to a skeleton's eye." He opens a hand, and a blue flame dances on the palm. He crushes it.

Frisk feels their SOUL turn blue. They fall flat on the ground, and blue bones shoot right through them to the ceiling. It didn't hurt them at all. The bones are like a ghost, simply doing no damage at all. However, the slightest movement can cause the bones to become solid and rip their insides.

"it says a lot. i tried to keep my faith in ya... but i've grown tired of waiting for you to change. you just love to learn the hard way, don't 'cha? you should had never came back here, kid. and i am not talking about this timeline. i mean, all of them. you should had died from that fall you took." At that last sentence, Sans' voice was poisoned with his rage. It is so powerful, his own voice sounds distorted. It sounds like he is talking through a spinning fan.

Frisk had no idea his voice could change like that.

Sans is defiantly pissed off.

Frisk watches him slowly lift his hand.

*Sans is sick of your crap.

"now, i am really angry. you should had moved on after you killed me the first time. now... i will make sure that you will never consider on going through the bad route again." He swings his arm, summoning orange bones that fly towards the kid. "these won't hurt you if you move... but the blue ones will unless you stay still. make your choice. patience, or bravery?"

Frisk realizes just how bad this is either way. Staying still or moving will cause serious harm.

They make their choice, they move, and the blue bones rip through them as they climb their way out. Their screams of agony makes Sans' eye glow brighter.

"this is what you wanted, right?" Sans' asks as the orange bones easily fly pass the kid like their are a ghost. He snaps, and gaster blasters are summoned. They fire ruthlessly.

Frisk falls to the ground, coughing madly.

*You feel a dangerous pressure in the air...

*Sans is not holding back.

*He is enraged.

"this is what you asked for, right? you must be bored, seeing the same thing again. so, let me keep things interesting." Sans sends more bones that shoot through the child. He swings his arm, sending the kid flying into a wall that shoots out a row of bones.

Frisk gasps and falls to their knees, bleeding heavily. They laugh lightly. They never saw this side of Sans before. They knew it was trying to surface since the first genocide run, but the monster did a good job at suppressing it through all these runs...

... until now. The 99th time, he finally cracked.

"you see what you have done. kid, crossing my line was not very bright. this is what i've been warning you about. i have already wounded you... and now i can't stop. so, answer this question."

Bones fly everywhere, slashing the child like knives. Frisk is forced to stand their ground and shield their face by crossing their arms over it. The force of Sans' magic causes a powerful gust.

Sans' jacket moves with the wind as he swings his arm again. Blue and orange long bones appear from thin air and rotate around him. He snarls out his next words powerfully. The distortion of his voice is just as strong. It sounds threatenly deep, drowned in pure rage. "are you finally happy?!"

So deep, nearly hard to understand since it was all said through a monstrous growl.

The bones shoot through the child in all directions. A gaster blaster hovers above, aiming at them.

"i will show you what REAL hell feels like."

The blaster grows twice its size before it begins to charge a powerful and gigantic blast... the biggest Frisk had ever seen.

As it prepares to fire, Sans slightly tilts his head back. "are you ready?"

It fires powerfully. The entire room turns white.

They stand against the edge of the wall. A gigantic hole had been made at the beginning of the hallway.

Sans is breathing heavily as he slowly lowers his hand. Gravel rains down as he fights to catch his breath. "heh... heh... so even with all that... i still...." He growls, and he swings his arm to the right, sending the child flying. He keeps doing this, summing bones at the same time.

He is using so much of his magic. He would normally be too tired or last to try this much. He would really be too lazy to try.

Then, it all makes sense.

Crossing the limit... it is called that for a reason.

Sans is so angry, he is putting every ounce of effort to try to destroy this kid. It is why he is using so much of his power. Frisk forced him to put in effort. Effort... into anything.

Sans stopped being lazy in his efforts to destroy the human child. He is pushing himself beyond what he had done before.

He stopped being lazy and is giving them his all.

Ting!

The familiar sound of a glowing eye.

Frisk grunts as they are slammed against the wall again. It cracks on impact.

Ting!

They are sent crashing to the floor. The tiles bursts out and stick up around them.

Ting!

Gaster blasters are summoned. They fire, and they leave behind heavy damage ss the child jumps across the room to dodge. Sans swings his arm to call out more bones that fly towards the kid. They dodge them quickly.

"it looks like you are avoiding these attacks with flying colors. let me fix that." Sans snaps. A small blaster appears behind Frisk and blasts them from behind. "ouch. that must hurt. though... it was a blast to see."

Frisk is flung into the air again.

"did that joke fly over your head?"

Frisk is slammed again. They can't move very well. They jumped off the wall in time to avoid the bones that shoot out of it.

"kid, you can jump all you like, but eventually... your little reign will be over, and you will drop. so... make this easier for yourself... and just endure the pain of your own crimes." He turns his hand, and bones surround the child like a box. They begin to close it and press against them, crushing them slowly. The child grunts and groans until they begin to shout in pain. "you don't know how it feels to have your hopes and dreams taken from you countless times. so, maybe if your spirits are finally crushed, then you will at least have an idea."

Frisk can feel their bones at the verge of breaking.

"i... i really don't want to do this. i would much rather stop this and just end it with one shot..." Sans forces out a laugh, but a tear falls from his face. "but it feels like my body is moving on its own. i told you about this... i have no control. it scares me to know what i can do when i am so... so angry."

Frisk feels their left arm snap. They bite back a scream.

"maybe if i... end your life slowly... maybe if i make you suffer like you made us... maybe then you will stop. perhaps agony is the only way."

Despite the pain, Frisk still shows him a grin.

"you... don't mock me..."

*You tell Sans he had always been too lazy to get his job done.

*You tell him that is why his brother will always fall as dust.

"..." Sans lowers his head with his hand still in the air. The bones crushing the child disappears, and Frisk falls. As he looks back at Frisk, his eye flickers. He seems to realize that, because he growls a second later.

His eye flashes yellow and blue before staying yellow.

"you are one hell of a masochist, huh?"

He swings his arm aggressively, watching the child slam against the walls over and over, losing 1 HP at a time. The pain written on the kid's face grows worse with each slam. "heya... you don't look so good."

Frisk is slammed to the other side.

"you just love to learn the hard way, don't 'cha?"

*Sans finds this humorous.

They are slammed again. This time, the air is knocked out of them.

Sans chuckles angrily. "what's the matter? did too much reality slam into you at once?"

He slams the child again. Bones shoot out and stab through them this time. He seems to be worn out even more. Breathing hard, he laughs again.

He swings his arm in many directions for 20 more seconds until he slows to a stop.

Frisk stands with their hand pressed against their left shoulder.

Sans snaps and around 8 blasters appear at once and fire. Many blasters appear and disappear, firing. Frisk dodges them Cleverly as the destruction goes on. The building shakes with each blast. They are fired a split second apart, chasing the child nonstop.

It ceases all at once. Part of the building's ceiling collapses. Chunks of it crashes on the ground.

Sans growls each time he exhaled, worn out and unable to move very well. He stares at the kid. "... if i could keep up... you would be dead where you stand...!" He places a hand over his chest, chuckling lightly. "my body can't keep up with my aggressive magic. but... still..."

Ting!

His eye is glowing a bright yellow as he rises his hand into the air. Countless blasters appear with even more countless bones. He is huffing out smoke through his teeth.

This is the most they had ever seen.

The attacks are fired. Frisk dashes left and right, ducking and leaning side to side. Many of the attacks graze them, and they stumble until they fall to a sitting position, hanging on to 1 HP.

Sans brings his fingers in position to perform another snap, but his hand shakes as he breathes hard. He slowly lowers his hand.

Frisk watches him fall to his knees.

Sans grunts before breathing again. "heh... using so much power was a bad idea on my part... oh, well... at least i did a number..." He watches the child slowly stand. "but uh... if i never stopped caring.... i would had destroyed you just now."

Frisk rises their knife.

The glow of Sans' eye disappears. He looks at his hands. His fingers are already starting to fall apart as dust. He doesn't seem surprised. "oooooh. so THIS is what happens when we use too much magic."

He doesn't seem to care. Typical Sans. It seems he had calmed down enough at this point.

"welp... no wonder. kid, i just realized that my rage made me overwork myself. there is no point in using that pointy thing on me."

*It doesn't matter, anyway.

Frisk lowers their weapon, allowing the monster to speak.

"my body couldn't handle it. it looks like i... put in too much effort...."

This is really happening?

Sans was battling so hard... he made himself get into a state monsters call "falling down". No wonder why he was so lazy.

He knew his body wouldn't be able to take it... because he had given up on so much.

Frisk begins to move on. They pass the dying skeleton like he isn't even there. With their weapon still drawn, they head for the King's garden.

TING!

The child spins around in time to see a blaster right in front of their face. Sans' eye is glowing powerfully once more. His hand faces the child.

"getttt... dunked on..."

FWOOOOM!

Frisk had crossed their arms over their face as a pointless shield. The explosion is huge, making the entire building shake and gravel to rain down. The cloud of dirt settles...

Frisk is still standing... with just half a point of HP left.

Sans blinks as the glow in his eye fades. He is completely shocked. For several seconds, he is quiet until he finally speaks. "i gave you my best shot... and you still made me look like a joke... and i only got weaker. heh... i guess my chances of stopping you just got cut in half....heh..."

The human child is left confused.

Sans bursts into loud laughter. His eyes are shut as his head is thrown back. His laughter travels down the damaged hall. It is not filled with joy, nor was it forced.

This is despair. He sounds insane.

He calms down at last as his hands falls apart. He shrugs one last time. "sadism is a burden. no wonder why we don't try to carry it."

He salutes the kid with his dismantling right arm.

"see ya, kid. i'm going to grilby's."

He closes his eyes as he falls as a pile of dust. All that remains is his coat, shorts, and slippers.

*Looks like he died from exhaustion.

Frisk stares at the dust pile. They begin to wonder.... what would happen he wasn't so lazy? How powerful would he be?

His brother, Papyrus...

... how strong is he really?

-OoOoOoOo-

It doesn't matter, anyway.

Frisk will keep fighting him until the taller brother dies from the overuse of magic that leads to exhaustion. They will force this monster to lead himself to his own death if the blade doesn't kill them first.

Does Papyrus even know that using high amounts of magic in dangerous levels, is like a human going without water in a desert?

Maybe he doesn't. Or, maybe his judgement had been altered.

But... what Papyrus and Sans have in common... they share a lot more than they would think.

But what differs is how Papyrus is losing his way.

"Nyeh-heh...." Papyrus rises his hand, placing it over his blazing eye. "I always thought that seeing Sans' with his one flaming eye was pretty cool, but he told me to never say it again. It makes sense on why. He even said I would never want it myself..."

Frisk waits patiently.

"Nyeh-heh... Now, I see why. I can see it. The pain behind it, and how you brought this out. Nyeh-heh... it hurts so much, human... It won't stop... and now..."

Something else is off about this situation. He keeps chuckling between some sentences. Is he losing all hope for a change in the timeline?

Or maybe he had lost his reason, clouded by the raging power he has?

"A-and now... I realize that Sans' was right about something involving your place in the world... so, let me express your situation as my brother would in my place."

Silence fills the air for several seconds.

"It's a splendid day outside. The birds are singing... the flowers are blossoming.... on days like these... humans like you..."

His hands catches flames.

"Should be burning in HELL."

Those words were poisoned with pure rage and hatred.

What happened to Papyrus?

Oh.... right...

At first, they hear a quiet chuckle, then it steadily grows louder...

"Nyeh-heh-heh... heh-heh...!" Papyrus throws his hand above and summons several blasters.

He seems to be becoming more aggressive by the second.

"En garde!" Papyrus pushes his hand forward.

The blasters fire madly, and Frisk is running and jumping in desperate attempts to avoid the attacks. The skeleton's blazing eye makes him appear truly insane.

Frisk is caught by many, and they die.

So they return, reach this point...

Frisk screams as many blasters fly past them. They are grazed, and they stagger before running again.

"He was right! This does feel great!" Papyrus throws his hands down in excited laughter. "Human, look at the destruction you've created! Not just in the underground, but in monsters also!"

Frisk stiffens. Their hold on their knife is stronger.

"Nyeh-heh-heh-heh! How many times has it been already?! 9? 10? 11?!"

Orange bones surround the skeleton and fly around him. He snatches one and holds it with both hands as he turns his body to the side.

*Papyrus is looking at you with a strange look on his face.

*He doesn't appear very sane.

"Come back all you like! The Great Papyrus will stop at nothing!" He jumps and swings. The child moves in time for the bone to go through them like they are a ghost.

Orange attacks... staying still means being crushed or sliced.

Papyrus seems somewhat bothered. He swings again and again. Each attack is dodged. He speaks more angrily. "I'll keep defeating you again, and again... until your DETERMINATION wavers! Then, I'll CRUSH it, and kill you again, and again, and again...!"

Frisk jumps back to avoid several more attacks. It is too difficult to read his wild movements. His mind is so scrambled with hatred and the need of justice and revenge, he is consumed by the reckless flames.

*Papyrus is cackling.

"Until alas, I get bored of it! But too bad for you, I am having a SPLENDID time!"

Frisk dodges a swing.

"Why do you look so upset?! Frustrated, are we?!" Papyrus swings his bone down. The floating ones shoot at the child who is sliced by some. His bone pushes against the push of Frisks' knife. He is close to their face as he continues. "Tired of dying?! Why does it bother you?! You've killed so many times before! More than anyone can count! So now, I will keep killing you until you give up!"

The weapons clash again. Frisk struggles against the strength of the push.

"Human, not once had I ever felt so excited to see you so... rattled! Wowie! Every part of me is tingling! Nyeh-heh-heh-heh-heh!"

Frisk ducks to avoid a bone swing, and they jump back. Several orange glowing bones surround them and shoot through them from many directions.

(1) "NYEEEH! HEH-HEH-HEH-HEH-HEEEEH!"

Their SOUL turns blue, and they are flung to the ground brutally by the magic. A blaster strikes them head on.

"What's the MATTER, HUMAN?!" Papyrus' voice is filled with insanity. It doesn't sound right at all, like his own voice is lapping over one with a darker tone. "DOES THIS NOT TICKLE YOUR FUNNY BONE?!"

But, something is different this time around?

Why is Frisk feeling uneasy from this situation?

It's intimidating, really. Papyrus' voice sounds slightly distorted... just like Sans' was when he was pissed off.

Is that a skeleton thing? It's like some "hidden" parts of their speech is exposed, reverting to some other "language" or something. It's not easy to explain.

A distorted voice. He sounds like he is screaming through a fan. One would think it would sound cool, but not when your situation is suddenly grave and overwhelming.

For Papyrus to give up all faith and let his rage seep in, one thing is clear;

*Papyrus has completely lost it.

Frisk for once is actually uneasy. They are shaken up by his behavior. Not once did they ever picture him like this. Sure, they wanted this but...

His "limit crossed" behavior is so different from Sans'.

It's like the flames in him took control of his mind.

Burning hatred.

*You tell Papyrus to stop.

*He doesn't listen. A funny look on his face is too noticeable.

"How about this, human?!" Papyrus thrusts his hand forward, unleashing another blaster. "And this?!"

FWOOM!

Frisk ducks their head as a pillar falls to the ground nearby from being struck instead.

Papyrus snaps heavily, summoning another gaster blaster. "I know! How about THIS?!"

They lunge over the fired blast and crash to the ground. They lie there, breathing heavily. There is no time to even rest. Already, the monster is preparing another attack.

"ARE YOU HAVING A GOOD TIME?!"

"Papyrus! STOP!"

Frisk gasps. They recognize that voice! Turning to the direction of it, King Asgore rushes down the hall and stands a couple yards away from the crazed skeleton. Frisk blinks, not expecting this monster to actually come out. Then again, Papyrus was sure making a racket...

"This isn't what he would have wanted!"

The mentioning of Sans seems to anger Papyrus. Instead of staying on the topic, he changes it. "And YOU, goat-man! Am I good enough for your guard, NOW?!"

The king actually takes a quick step back.

Papyrus throws his hand up, sending Frisk flying into the air. A gaster blaster is summoned. "I'LL MAKE SURE THAT NO HUMAN EVER REACHES THE SURFACE AGAIN!" At the last word, the summoned weapon sends a huge blast. It rips through Frisk easily.

Their SOUL splits.

Darkness again...

Flowey's voice is heard. "Yep, I really like what he is doing here. This is good. I really enjoy everything about this right now."

He sounds more relieved that he won't get hacked down any time soon.

CONTINUE.

And so... this is happening.

The nice happy skeleton is now fueled by hatred and the need for vengeance. A horrifying mix.

This is the very first time Papyrus has ever stopped showing mercy, after all.

A/N: It is nearly done. Yay.
(Yes. I drew that comic.)

So, uh... basically... there were a few inspirations here too.

The whole "Crossing the limit" thing was made up by me. Since humans and monsters differ in behavior and faith due to DETERMINATION, well... I did that.

Also, the idea of monsters dying from using too much magic is what I believe is like us dying from overworking ourselves.

You saw a number 1 next to a paragraph. Here is why:

When Papyrus was attacking Frisk madly shortly after the flashback, it was from a few other panels from the comic I told you about before. It wasn't seen on the video link I sent.

Another dubbed version of this comic sparked something else. The idea of Sans and Papyrus having a slight distortion in their voice when they are pissed the f off is from that dubbed comic.

The slight distortion sounds like how your voice would sound when you talk through a spinning fan. Hehe.

I also edited Sans' limes when he was enraged. For him to scream out his words didn't seem right. He speaks in lowercase letters. Also, when you fight him in the game, he was so chill with how he talks. So, I figured that instead of him screaming at you when enraged, he would actually talk in a more deeper tone through a growl.

I was pondering about the change until Man on the Internet . Sans in there sounded angry as he sung in a way that suited him. Check it out for yourself.

It's fun to do.

A/N: Hey, guys. I originally had no plan to have this note here, but I had this idea in mind for months now.

Pay attention.

My 2 stories: "Crossing the Limit (Undertale)" and "Undertale: The Pain of Disbelief", those two stories are linked in a way. I suggest looking at "Crossing the Limit (Undertale)" first, though. (Wait. You already have.)

Why?

I actually have this Undertale AU in mind. Both were inspired from the Disbelief AU of course, but, I want to make my own. What I made was originally an AU, but I realized it was more of an Alternate Timeline.

(I know. We have enough already.)

The AU (Really, it's an Alternate Timeline.) will be called: "Barbarictale" why? (I originally wanted it to be called "Limittale" but it was taken. So was "instinct", "impulse", and "feral." Sigh.)

Well, Barbarictale will be an Alternate Timeline, but at the same time, an AU due to so many resets casuing a new branch on the multiverse. The story and characters are the same... But with a twist.

(Inspired from Undyne the Undying as well.) Well, if the character does a genocide route or neutral in some occasions, there is a risk.

This Alternate Timeline/AU was "formed" after several genocide run resets. The monsters seem the same, but their clothing is diffrent in a way. (Will be described later.) Monsters are much more difficult to convince to show mercy. (Except Papyrus.) Some monsters are cruler than normal. In battle, their attacks are more violent than normal. A few monsters will fight you harshly at the sight of a human.

Many monsters are stronger than they were before.

Basically, the monsters are a little less nice to you and other monsters. (Some will talk rudely or with sarcasm.) For example. Undyne is cruler with her words.

If you attempt to kill them, they will begin to try to kill you. (Yes. Even Toriel, because she grows suspicious of you.)

For them to show mercy isn't easily obtained since they do not trust in others easily as they do in the game. Befriending them is more difficult since they are wary of your presence. Mercy-kills are impossible. If they spare you and you try to kill them, they will only take regular damage since they never let their guard down. Then, they will try to kill you. (Remember. You did several genocides before, so they had the feeling you are dangerous.) Because of their lack of forgiveness, they are very dangerous to enrage.

As seen in the stories I wrote, "Crossing limits" of a monster is dangerous. Meaning if you push a monster over the edge to the point they become enraged, they become at least twice as powerful as they usually are.

At LEAST.

Because they begin fighting using all of their magic beyond their limits. Their appearance will change as well, and they will behave more brutal and more like an uh... Monster.

Okay… not a dramatic change in appearance.

For the sake of the Alternate story, I guess they can all wear different attire like they do in other AUs. Their attire can look a little more intimidating, but not too much in a way that would make them look scary. (Nothing scary-looking like Underfell, for example. But a little close to it in a way.)

Enough that they would seem like monsters, but their kindness makes the attire look nice on them. (Wow. It is so hard to describe.)
The color of their clothes would be darker, too.

Anyway, as for their main appearance... it will slightly change when their limits are crossed.

For example. In the story, when we have Sans. (Lol. Might as well call him Barbaric!Sans) He begun using so much magic, it started to leak out. It leaked out as erm... Smoke seeping through the corners of his mouth. (That makes him look pretty badass.)

Read "Undertale: The Pain of Disbelief" to get the idea of what I am talking about.

Papyrus is the same way. And when they speak, their voices sound the same but distorted.
Aye. (Barbaric!Papyrus is seen in "Crossing the Limit (Undertale)" as the root of all this.)

I already have those 2 down.

Also. When monsters are in that state, they can "see right through you". Meaning if you had done a genocide beforehand, they would get the idea that you had slaughter everyone before.(Or simply, they will know you are dangerous and cannot be spared.)

When you fight them, their theme will be the same, only intimidating and gives a "you are going to die" feel.

They will also sense bad intentions in anyone else.

They would realize their "nightmares" or "dejavus" are real.

Some monsters can see the truth behind someone's intentions better than others. Sans can easily do it since he can read your expressions to get the idea already.

Imagine that.

The downside is, a crossed monster is enraged, so even if the target had never done anything bad before, since they crossed the monster, they clearly had done something bad at the moment. The monster would still go after them.

Thankfully, the monster intends to target the one they are enraged towards. Anyone else, they would simply shove away.

Also, anyone can force a monster to become barbaric if they inject some sort of needle for example. But that would cause the monster to attack anything.

Great.

Back to attire.

The whole point is to draw them to look like some monster that will tear you to shreds when they are in the crossed limit state. (Yeah. I had this idea in mind since October...)

Goodness. Why the heck is this so hard?

Okay... So if we have the Dreemurs with their "limits crossed" then... perhaps they would have glowing red eyes. Yeah.
Breathing out real smoke since they use fire magic.
Can possibly breathe out fire like a dragon.

Barbaric!Undyne would be almost like her undying form. Black eyes.

Barbaric!Alphys would have red eyes too. More Reptile-like. She would actually fight using electricity and such.

And... When they are like that, they pretty much lose control of themselves. Yeah.
You know how you go into rage and you stop yourself with enough willpower?

Since monsters do not have the DETERMINATION, once they have their limits crossed, they cannot be stopped... no matter what. They become merciless, full of malice.

If a monster fights in their limit crossed state for too long, they would fall down due to using too much magic. Sans would fall down easy since he lacks stats and such. But he would last for a good 20 minutes at most.

They would fall down (die) for 2 reasons, actually.
1. They use too much magic. Since monsters are made of magic, and their souls are attuned to it... Magic holds their bodies together. Using so much means they won't have enough to keep their body in shape, so they fall as dust.
2. This is a rarer case. A monster SOUL is made with compassion and love. (Not LOVE.) without those positive emotions, the soul cannot exit.

So what happens when they lose their compassion towards an individual due to rage? As long as they still care for others... they can still live on. But such feelings are hard to hold on to when they had gone berserk.

In "Crossing the Limit" Papyrus was an inch close to having his limits completely crossed. Flowey only succeeded 80%. Because of this, Undyne was able to snap Papyrus out of his temporary rage.

Until now.

Okay. Moving on.

Also, how awesome would it be to hear them roar? They aren't human... You know. Monsters can roar, right?

Wait. Fish can't roar.
I guess Undyne could be snarling for all I know. She has the sharp teeth to look intimidating regardless.

(Is she like a piranha or something?)

Anyway, "Crossing the Limit" is a dangerous phase named for 3 reasons;
1. You crossed their tolerance and enraged them.
2. They fight beyond limitations, overusing their magic to destroy you.
3. They toss aside their usual behavior that would hold them back to break through their limitations in a regular battle. (Ex. Sans stopped being "lazy" and have his all. Papyrus stopped being nice.)

It is forbidden for anyone to try to do such a thing since the ability is feared and all. But Frisk decided to see what would happen and would try to cross limits.

Each boss is difficult to cross in a way. FIRST, the requirement is for you to kill some monsters for them to be aware that you are killing. Genocide isn't required. Then, do this:

*To cross the limit of Toriel, you will have to taunt her or say cruel things to the point she won't see you as her child.
*To cross Papyrus... Heck. He is THE MOST DIFFICULT to cross. It would take countless tries, I bet. Insults mostly fly over his head. Actions work better than words.
*To cross Undyne... well... I dunno. Kill Monster Kid or something? (Okay. That's mean.)
*To cross Mettaton... Well... Actually... He's a ghost so it may not be possible.
Maybe. If you mess up his body or whatever.
*To cross Alphys... expose what she did to the whole underground. Make Undyne dislike her in some way. Break Alphys' heart. Kill Mettaton. Whoa. Whoa. That's messed up. But, you will get a boss fight out of her.
*To cross Asgore... I guess you will have to taunt him about what he did or threaten to kill his wife.

But that's the whole point. Target any monster by their weakness and use it to crush them and hurt them to the point they get mad and want to kill you.

-0000-

If the player is close to crossing their limits, the game or the monster would give them a warning.

Game warning:

*Alphys' tail twitches strangely.
*Don't push her too far.

Monster warning:

Papyrus: I'M BEGGING YOU... NO, I'M WARNING YOU TO STOP. B-BECAUSE I DON'T LIKE THESE TERRIBLE FEELINGS I AM GETTING.

I... I AM AT MY LIMIT, HUMAN!

If the player successfully crossed their limits in battle, then the game would say this when you do ACT.

*Looks like you crossed his/her limit.

And it would say something beforehand and after that text. If it were Sans, then...

*You can hear deep growling now. Sans seems really sick of your crap.

ACT:
Sans - 2ATK. 2 DEF.
*Looks like you crossed his limit.

*Smoke is seeping through his teeth. He isn't holding back anymore.

Then, he would still talk. But his words are more harsh;

"i am through with this, kid. you are asking for the worst time of your life."

And he will make puns. Still.
Mean ones.

-0000-

Monsters talk and fight crueler in the state as well. Barbaric!Papyrus is no longer Mr. Nice Guy.

He becomes downright rude.

And they will want to kill you. They also fight like the definition of a "monster" we know that isn't related to Undertale.
(Like a wild animal, I suppose. Not entirely, though.)

The more tame stage is that they can still talk, but they still can't stop themselves from hurting the target. (As seen with Sans and Papyrus in the 2 books.)

The untamed state is when they simply lose the ability to talk at that moment, only able to make terrifying sounds or whatever.

The whole point of this Alternate Timline is this;

They are monsters who are like humans. They are civilized. You forget that they are monsters and see them as people.

Until the reach a state; "Limit cross" or "Crossed limit". Then, you remember they are monsters.

When their limits are "crossed" they revert back to "true" monsters. The kind of monsters that is expected when you hear the term.

Something that is dangerous. It snarls, hisses, and roars.

Something that will kill you quickly or by ripping you to little pieces.

They will no longer act human.

But, as for the one who caused them to behave this way… here is your question:

Who is the real monster?

What is sad is… when it is all over and they calm down… they feel guilty, horrible, because they couldn't stop themselves.

Then, they are afraid of themselves.

Can you imagine blacking out in one moment and wake up, only to see destruction around you, and a half dead (or dead) person underneath you?

And many eyes staring at you in fear?

... Okay. I'll stop here.

That is just my silly idea. A part of me wants it to become known.

Art inspired from this is appreciated. But the Alternate Timeline is what I created.)

(Just as Disbelief is owned by FlamesAtGames. I placed that in my story description.)

SO NOW: I said what I said… would I MIGHT write a story with a chapter focused on a main character in their crossed state.

Perhaps you want to do it, in writing or in comic form? If you do, that is totally fine. Just inform me.

Okay. I will let you be now. I apologize for the long note.

WATCH:

You can hear the voice distortion after Papyrus in the comic shouts: "Instead, I am going to have lots. Of. FUN!" and his mad laughter. The quotes spoken from there are the inspirations.

Okay. Now that I got that out the way, I'll leave you be.

Please do check out my other story, "Crossing the Limit (Undertale)" while you wait for the next update!
