He hid as the human walked out of the elevator, frying pan gripped tightly. He knew what was coming next. They were going to the abandoned Mettaton Resort, to the core. There, they would fight Mettaton. Papyrus had hope in him, but if the human could beat Undyne, who could?
They entered the resort, and walked right to the other side with the cowboy hat tipped down. They entered the core, out of sight of Papyrus.
"Well, this is it, Mettaton. Do your best. We all believe in you."
After he ensured that the human was gone, he entered the resort and checked for any remaining residents, just in case.
He found the clerk of the burger joint still at his post, for some odd reason. He looked timid as ever. Papyrus looked beyond the orange cat monster and saw many cigarettes piled up in the back.
"Why are you still here? You should be back at the lab with Alphys!" He said.
"Look pal, the Mett found out I left my post, I'd be dead where I stand. If you think I'm gonna move from this spot anytime soon, you'd have an even bigger pile of cigs than me," said the employee.
Papyrus moved on, not caring if the employee wouldn't leave to safety. After all, the human already passed by him and he wasn't dust, so he seemed safe.
He looked in the guest rooms and dining area, and found that everyone had left. With a sigh, Papyrus teleported to the core just as the human entered Mettaton's awaiting room.
If Mettaton failed now, there would be little hope left. Only him and Asgore would remain after that, knowing that the evacuated monsters had evacuated for a reason. Some sort of transformation started to happen inside the closed off room, along with blasting music.
Papyrus' hope was greatened, knowing that the rectangular celebrity had transformed into something in more powerful.
Hearing that some sort of powerful blast had taken place, he, staying on the positive side, rushed into the room once the doors had opened.
There was no human blood.
There were no human remains.
The only thing that was left in the room…
Was a pile of scrap parts.
