Summary
Sans knew. He knew everything. He was well aware of how miniscule his existence was compared to the many players who took the body of Frisk and ran them through the Underground just for the fun of it.
He could almost see the darkness behind Frisk, pulling the strings. He knew that his world was made up of code. He knew his father was lost in the corrupted files. He knew that Flowey was far from the worst danger out there.
Despair and carelessness was difficult to resist, but Sans was nothing if not patient. There was always a yin to the yang, and he was a smart man. He just had to boot up that machine again, and call for someone else.There was always a Player 2 to the Player 1.

Summary
Sans does not cave under the knowledge, the burden of knowing that everything could be torn away from them like a stuffed doll from a child. Sure, he's been practically nicknamed lazybones and his breaks are many with few work-related progress in between; but he manages to scrounge up enough cash to pay for rent and attends to his post every so often just to appease his brother. He doesn't quite give in, and he's DETERMINED to never do so, as long as Papyrus is here. Resets are actually a relief, strangled and corrupted they may be, once he's gone. Even if he'll just be cut down again eventually.
Of course, regardless of his not-quite-steel resolve Sans has his bad days.

Spending Spring Break Underground by 4Trixs_Animations3

Summary
Once upon a time many centuries ago, the world was ruled by two species: Humans and Monsters. Both of these creatures thrived together using their special talents to help one another. That was until the humans declared war on the monsters out of the blue. This led to the monsters to be banished beneath a mountain.
But rest well when I say the humans suffered their karma. Without monsters they soon lost their magic, along with their way of life. They developed their own powers called quirks, with this power came the raise of heroes and villains. Quirks were quick to spread until only 20% lacked them.
It wasn’t long before magic and monsters were reduced to legend. This led many to climb the mountain to see if the legends were true, only to never return. This was because of the heartbroken monster king who put a bounty on every human who fell.
When the last human fell, the monsters were ecstatic. Finally they’ll be free to wander the surface and feel the sun and the rain again! But unbeknownst to them, they have become even more trapped than they had before. With each reset the monsters were forced to live the same day over and over without anyone knowing ... .Well, almost everyone.

Summary
Sans didn't know what his name used to be, All he knew was that he was a human at some point, and that he was older then he was mentally and physically.
And when he blinked and he had a tiny bile of living bones in his hands, he knew he would give his life for his new baby.
Even when war crashed on the nation, he took it along himself to fight in the war effort in hopes for a better future for his son, he had later found out the baby was his brother, but he would forever be his son in his heart.
Papyrus was the reason he kept going, to strive for a better future.
Becoming chief in command wasn't a surprise.
It's when he appeared in a basement is what surprised him.
Why is there so many versions of him?
Why are they so tiny?
Why do they keep looking at him like that?
He just wants his son back for stars sake
He needs retirement after this, he's getting too old for this.
------
Or in which a human is in the body of sans, goes to war for a couple of decades, and finds himself in a house full of versions of himself, and tries to take care of his son along the way.

Summary
Ah yes. The classic ‘’Heather’ convinces the skeletons you’re an evil human so now it’s a EVIL reverse harem’. Right?
Oh? But what’s this? A TWIST?
Sans couldn’t live with himself after what happened to you, going near insane after you’re gone. So behind the others back he uses the machine to undo what he did, except it didn’t. He can still feel his sins crawling on his back.
Oh well, it’ll all be worth it once he has you back in his cold hands again. Screw the other skeletons.

Summary
There was no hope.
There was no way out of this place. Sans knew that from the depths of his soul- he couldn't escape on his own. But without any way to contact anyone and no knowledge of where he's trapped, all he could do was try to survive... or maybe just hope for death.
No more resets, after all.

Summary
Or: The one where an adult Frisk wakes up after their funeral, back at the beginning of everything. Of course, they know how to navigate all their adventures underground, but... Does anyone want to tell them what kind of sin they committed? After waking up each time, in different timelines, some of which they even know they generated, and others that they themselves didn't commit? Yeah, this isn't going to happen (it happens anyway).
