You make your way into a strange looking room. This could be no other than one of Mettaton's-

"Oh my love," cried out Mettaton in a horrific voice.

"Has fallen down,
Where'd they go?
They loved me so..."

"Now killing,
To slay the king,
What happened
To our best friend?"

"Sans is gone...
And Undyne too...
Cant hold on...
Then make us turn to dust..."

"Why'd you come,
Do you feel numb?
Please reset,
And all of us forget..."

The song was thankfully over.

Suddenly, with an evil grin on the princess, he pushed the button and you went tumbling into the stupid puzzle from Snowdin. This time, it wasn't simple.

"Good luck solving this one, darling!"

You furiously walked around the maze guessing and getting it wrong. Eventually you became stuck. You couldn't escape. Then, the sound of doom echoed from the clock to your ears. Time was up.

"Oh, what a shame," said Mettaton, hovering above the whole puzzle. "You haven't even made it halfway across..."

Walls of Fire started spewing from left and right, like walls of spikes, but much, much worse. They slowly closed in on you until they short circuited and the lights came off, as well as the lit floor, which now was gray and the powers wore off, becoming just a regular, colorless floor.

"Could we get a technician in here, please? Our equipment keeps malfunctioning and the viewers are dying to see the human die!"

You try walking away. Mettaton stops you.

"Now hold on just a minute..." He said. "You're not going anywhere." He said, screen inches away from your face. Stage lights came on, turning Mettaton into a silhouette.

"I think it's time I showed you my true form..."

Mettaton's silhouette Started transforming and changing, until he turned into Mettaton EX. Smoke cleared and more lights came on, showing Mettaton's fabulous legs and body, making anyone swoon.

"Let the battle... Begin!"

Things just got tense. The floor lit up with passion. They got the power back on again.

"It's showtime!"

You start in the middle of the puzzle. Blue lasers come from the bottom of the box to the top. You sit patiently. You attack. Mettaton dodges with passion.

"Can you keep up the pace, darling?"

The puzzle slowly moves down as you try to make your way up the puzzle. You succeed, and attack Mettaton. His arm was sliced off. Luckily, he had spare arms, but only one of each.

"Rgh! You leave me no choice, human. I must transform into..." There was a dramatic pause as the lights flickered and Mettaton changed shape.

"METTATON NEO!" Shouted Mettaton as he became bigger and stronger. You attack...

But he does not fall.

"Do not look so suprised, human. Alphys made some modifications before you came."

Mettaton was ready to finish you off. But then, a phone was ringing. Mettaton answered it.

"Mettaton! You can't fight the human in that stage, you'll die!"

"Darling, it's the only stage I have that can kill the human for good! Don't you remember the talk about determination?"

"Y-yes, but your body can't handle it! I made some modifications, but they still needed some tweaks!"

"It's fine, Alphys. I have it under control."

The phone ended.

"Keep dancing, human!"

Orange lasers were now moving across the screen upwards, along with the puzzle. It was fairly easy. You slice at Mettaton. His right arm was cut off. His second arm grew back.

"Now for the REAL action."

Blue and orange lights were coming down as the puzzle moved upwards. You get hit once. The screen was recorded. You take MTT's  left leg off. It was replaced.

"Let's watch that back, shall we?"

The puzzle was exactly the same, but going in other directions. You take off MTT's right leg off. It was replaced.

"Time for some old fashioned dancing!"

The disco ball came from above, as you shot at it, and the mini Mettatons falling from above. You take off MTT's left arm.

Lasers came up from the left side and other lasers were going down on the right side. You take MTT's right arm off.

"Rgh.. who needs arms..." Mettaton caught his breath. "With legs like these?"

The puzzle lit up as the disco ball was on and mini Mettaton's fell from above. You strike MTT's left leg. It falls to the ground. He somehow still maintains balance.

The puzzle was on as lasers were coming up and down on either side and bombs fell. You remove MTT's other leg. He sits morionless.

"Let's see if you can survive THIS, human!"

Everything was on at once. Lasers, disco ball, disco floor, mini Mettatons, bombs, and it was recorded. You strike Mettaton. He had less than half health.

The previous attack plays in reverse, and lasts twice as long. You dodge. You strike Mettaton one last time.

"No... it can't be... you really are a monster..."
