(This was a Undertale and MCU/ Avengers crossover! Description: Sans didn't know how the humans would react to monster kind on the surface... their reactions were always so unpredictable. sometimes they would be welcoming, sometimes not. Just depends on the pacifist routes... What frisk changed, or what happened to get the monsters free.

But, what he didn't expect was that this timeline was changed... it was a normal pacifist route, nothing was different about it... so why was there suddenly superheros on the surface?)

Sans sighed softly, a small frown on his face as he was packing up stuff.

Today they were finally heading to the surface... Again.

Sometimes Sans wished that the kid would just.. Stop. Stop resetting.

But, even if they promised.. They would usually break it and reset due to boredom. It aggravated Sans so much... Yet there wasn't much he could do about it. The kid had control over the timelines, not him...

It didn't stop him wanting to bash their skull in for being an ass though. But meh.

He could hear footsteps bounding to his door before it slammed open, revealing the tall skeleton known as his brother.

Sans grinned lazily at his brother, raising a brow," wassup bro?"

Papyrus exclaimed happily," ARE YOU ALMOST PACKED BROTHER?! THIS IS THE CHANCE WE ALL HAVE BEEN WAITING FOR! THERE'S NO TIME TO BOONDOGGLE! OH, I'M SO EXCITED!"

Sans' expression slightly darkened, it unnoticed by papyrus," hehe... Yeah, almost. Just got a couple more things... I'm sure you are excited paps. I could definitely use a nap right about now."

Papyrus sent Sans a look," BROTHER, I DO NOT WANT YOU FALLING ASLEEP! IT'S A SPECIAL DAY TODAY AND I WILL NOT HAVE YOU LAZYING ABOUT!"

Sans' grin widened A bit more," come one, paps. I'm so bonetired right now.. What, am I not hitting your funny bone?"

Papyrus' eye twitched before he sighed," JUST... JUST DONT FALL ASLEEP, OK? WE CANT BE LATE!" With that, the taller skeleton ran out of the room.

Sans chuckled softly, mumbling under his breath," Ok..."

He glanced at his almost packed room, and aching feeling in his soul, it feeling as if it was weighed down. He sighed, rubbing his skull a bit before his magic eye lit up, him using his gravity magic to finish packing his stuff. He glanced at the key in his hand, having found it in one of his drawers. He sighed before putting it in his pocket. Might as well keep the thing... Not like he isn't coming back or anything.... He always comes back here...

Sans slumped, leaning his back against the wall near him. He then slid down, bringing his knees to his chest with a tired sigh. Nothing about this was new... Nothing. It was the same old thing...

Sans closed his eyesockets, setting his chin on his knees, hugging them close. Might as well sleep on it.

It didn't take long for him to be woken up by Papyrus yelling," SANS, WAKE UP! IT'S TIME TO HEAD TO THE SURFACE!"

Sans yawned, stretching while replying back," Ok , bro. I'm up."

Heh.... Might as well try. For paps...
