Harry potter was standing on top of a building in New York city. He watched as demon like creatures made their way towards him.

Their body's flooding a thick black substance as they crawled towards him. Harry eyed them carefully as he reached for a dagger he kept in his back pocket.

He had been traveling far, but now he had to stop and deal with theses demons. Harry jumped onto another building and rolled into a standing position.

A demon came up behind him and he twisted his body around and stabbed the creature in the chest before extracting his dagger and stabbing another one.

Harry swung his leg and kicked one making it fall ways several feet. When he noticed the multitude of demons appearing he ran to the side of the building when suddenly a large demon swung and hit him so hard he flew back into the building behind him. Going straight through the glass knocking the air out of him.

Harry then slammed into something behind him breaking his back and his skull. Blood started pouring out his nose and his head.

Harry stood up cracking his back into place, it started healing immediately. He could feel his head starting to heal, but much slower.

He was about to charge at the demons that were now crawling through the broken window when a blast of energy shot past him.

Harry could hear voices and yelling from behind him. Guns were being fired and what looked to be a hammer. Harry turned around and noticed several people fighting the demons.

He was about to join again when he was hit in the head again and flung into a bar. He heard his ribs snap while glass punctured vital organs. The last thing he knew was someone placing a hand on his back before darkness took him.

The Avengers were all at Stark Tower relaxing after what had happened with Loki and his army of Chitauri.

They had defeated Loki and sent him back to Asgard. Thor stayed though which they were all happy about. They were having light conversation when there was suddenly a loud crash above them.

Everyone immediately went for their weapons and raced upstairs to see what the commotion was. The first thing the saw was a boy no more than 18 standing facing a huge hole in the glass window.

He was covered in blood, a dagger lying at his feet. The next thing they noticed were black slimy creatures crawling through the broken window. Natasha brought up her guns and started shooting at the creatures hurting them but not killing them.

Thor threw his hammer, while Clint shot arrows and Tony blasted them. Dr. Banner stayed out of the way for most of it.

Not wanting to turn into the other guy and reek havoc everywhere. Steve not having his shield picked up the dagger and started to stab the creatures with it.

It was then that one of the creatures came up behind the young boy. Steve tried warn him, but it was too late.

The creature slammed itself into the boys sending him across the room and slamming him into the bar.

Everyone could hear the boy's bones break and saw deep cuts appear all over his body. Tony blasted the creature killing it.

Thor made his way over to the boy and placed a hand on his back. He then picked up the boy and laid him on his back on the floor.

"Is he still alive?" Steve asked. Everyone surrounded the boy. Thor leaned over the boy's chest, his heart was still beating. "His heart still beats" Thor informed his team.

"How's that even possible, you all saw how he was thrown." Natasha said shocked. "I don't know, but we need to get him to the infirmary."

Thor picked him up while the others followed closely behind. "Someone needs to call Fury" Steve said "Jarvis" Tony called out.

"On it, sir" Once they entered the infirmary Thor placed the boy on a bed. Tony and Bruce started to hook up wired to the boy while Steve and Natasha started to look over his wounds taking out glass shards and wrapping the boy's abdomen.

Right when they finished Fury and Agent Coulson walked in. "What happened" Fury asked thought it sounded more demanding.

"We don't know sir everything happened so fast. "Well you better figure it out" Fury said sarcastically.

"We heard a crash and when we got there he was just standing there and there were these black scary creatures coming in through the window." Tony relied.

Everyone nodded in agreement. "Then how did this kid get in?" Nobody said anything not knowing what to say. "I think I might be able to help with that sir."

"Jarvis"

"He was thrown through the window causing it to break."

"Jarvis, if that really happened the boys would be mince meat."

"I know sir, but that is what happened." A video appeared and everyone's eyes went wide when they saw that Jarvis was telling the truth. "Impossible"

"When he wakes up we are going to have to ask some questions." Everyone nodded in agreement.

.....An hour later.....

Harry woke up in a bed. He didn't know where he was, all he knew was that he shouldn't be there. He then noticed wires hooked up to a heart monitor. Quickly he detached them and made his way out of the room. He kept his back to the walls as he made his way through the corridors.

..................

Everyone was in the kitchen waiting for when the boy would wake. Tony had said he was doing pretty good and should be left alone.

Thor and Steve were both very worried about of the boy while Natasha was conversing with Fury and Coulson. Clint just sat alone thinking over everything.

"Sir the boy has left the infirmary" Everyone started running in that general direction, searching to see where he could have gone.

"How is that even possible his wounds were too extensive there is no way he could have woken much less walked out."

"There are many things we don't understand" Thor said. "Everyone spit up and look for him" Fury yelled. So that's what everyone did each running in different directions "He couldn't have gone far."

...................

And don't ask me why they didn't just ask Jarvis where he was, this is how I wanted the story to go.

................

Harry could hear yelling nearby and quickly ducked into a room and silently closed the door. He let out a breath and looked around.

It looked like a bedroom. There was a king sized bed in the center with a dresser to the right and nightstand to the left.

Harry made his way deeper into the room when suddenly the door opened revealing a big burly man with blond hair. (It's Thor, not cap)"There you are" The man said walking forward.

Harry moved back not wanting to be close to the man. "Who are you?" the blond man asked. "That's none of your business"

"Is it when you are in my room and I have the right to ask who you are." Harry said nothing

"I am no threat to you or your friends, I don't wish to get mixed up in this." The man nodded "At least tell them yourself, just talk to them." Harry didn't want to. But ended up agreeing anyway.

"Promise" The man smiled "I promise" Harry said as he started to walk towards the door. The man opened the door for him and he walked through to the hall.

"Jarvis tell everyone to meet us in the multipurpose room"

"Of course sir" Harry didnt jump at the voice knowing where was it coming from. "Don't worry" The man said as he lead him to the others.

The man then lead Harry to the living room. He noticed some of the people from earlier standing in the room, while more were coming from other directions.

"I see you have found him, good job Thor." Harry turned to face Thor a surprised look on his face. "Thor, Norse god of thunder" Thor smiled at Harry "Yes that is I" the man said with pride. "And all of you-"

"I think we're the ones who should be asking the questions." Harry just ignored him and continued to speak. "-are the Avengers, yes I have heard of you"

"Well we haven't heard of you. What's your name?" The black man with the eyepatch said, but Harry didn't reply.

"We could do this the easy way or the hard way" Fury threatened. "Are you threatening me?" Harry asked deadly calm. Harry noticed many of the avengers tense up at his words. "Yes if you don't answer our questions"

"Just answer some questions for us" Steve said. Harry looked at him then back at Fury. "Ask what you must, but I will only answer what I want." Fury didn't seem to like that answer, but started asking questions anyway. "What is your name?"

"I will not give you my full name, but you may call me Harry." Fury looked angry and looked to the agent next to him. "Ok, how did you get in Stark Tower?" Harry smirked "well isn't it obvious or are you that stupid."

"So you smashed through the window?" Tony asked. Harry nodded his head yes. "How did you survive?" Steve asked "How did you survive in ice for 70 years."

Harry countered back. "He's got a point" Clint stated "Not helping Legolas" Tony shot back. It was then that Natasha spoke up.

"We found this with you. Were you fighting those monsters?" She held out a dagger, but made no move to give it to him. Harry smiled at her "Yes I was and I'm sorry to have involved you, it was not my intent."

"Than what was your intent?"

"Like you I help people, now if you could excuse me have places to be." and with that he was gone.
