Papyrus is his new master and now Sans needs to get used to this new life. But maybe it's not as bad as he assumes it will be? NOW COMPLETE

Player can't remember anything from before the game, before his body was mapped out in simple binary, and his mind became nothing more than a control for his avatar. Player doesn't know why there are 4979 people living in that world. He does know that, when it comes to companionship, he's the odd man out. Unfortunately for Player, the system has a solution, and it results in murder

Frisk tumbled down, down, down, into the darkness, which was waiting with open arms to engulf them. - The Underground decayed as monsters lost hope. Monsters became obsessed with games to try and pass the time in their underground prison, even revolving their whole society around them. Frisk is a natural at games.

Dr. W.D. Gaster always knew there was something very unique about his apprentice, but he had no idea he was keeping secrets like THOSE. Could Sans really have been holding the key to breaking the barrier this entire time?

The barrier was broken, and King Asgore and his great and terrible army conquered the surface, leaving destruction in his path.

Monsters are sometimes humanoid, but even so, very distinctly un-human. Skeletons, on the other hand, are very different creatures. Why is that? And why do they seem to be the only ones?

Meanwhile, one question lingers in everyone's minds: Is Asgore really fit to be a king?

[My AU] Papyrus hasn't had the best childhood. Being orphaned along side his older brother and then living on the street at a young age doesn't even grace towards the top of the list. Perhaps losing his brother to a psycho who decided to keep his sibling as a pet was nearly the top but was no where near all of it. Especially after he forms a solid plan to get his brother back.

In his heart, he will always be Kili Baggins.

When Frisk participates in an experiment involving alternate universes, they accidentally get stuck in another world.

The universes, in chronological order, are StoryShift (ut-storyshift, Tumblr), Underfell and Underswap (underswapped, Tumblr).

Sans builds a machine intended to travel back in time, but instead it opens up a gateway to an alternate universe. After a mistake he didn't even know he made until too late, he and his alternate selves scatter across the multiverse, and it's up to him to bring everyone back to their home worlds.

"the need for order, for control, for things to be neat and tidy and by-the-book - that's always been there" (or, Minkowski's thoughts during that long and terrible pause after the call to Cutter in Wolf 359 Episode 14, "The Kumbaya Approach.")
