We all know who the king of monsters is. He is soft, and bright, and large. But do we really know everything about him? He had to have a life before being king, right? Join Asgore, Toriel, and Wing Dings Gaster as they grow up in the older days when Asgore was just a small prince. (R&R, T for violence and language.)

When a small prank goes wrong, Frisk is left as a toddler. Now, Toriel, Sans, Papyrus, Undyne, Asgore, Alphys, and yes, even Flowey are left to care for her! (Female Frisk and Chara)

After almost completing genocide, Frisk resets everything and starts the true pacifist ending. But some secret force is Determined to set things right. This story mainly follows Sans and his reaction as well as what he does during this time. Rated M for bad language and scenes that contain violence.

What happens when Spring Bonnie comes back to life? What happens when he realizes he has a human's decaying body stuck inside him. What happens when Purple Guy's ghost follows him around constantly and annoys the living heck of of him? HIATUS

Relatively short, happy chapters about life on the surface where Frisk, Toriel, Sans and Papyrus live together. Some hurt/comfort but nothing depressing, mainly happy monster family fluff. Romance is not the main focus, but there is Alphyne, eventual Soriel and Papyton bias. Alphys, Undyne, Asgore, Mettaton, Monster Kid, Asriel and Gaster (and more) also show up.

Starting a new life in Ikebukuro, your daily life is much more troublesome than before. You'll meet all the famous people that you never wanted to see, you want to stay away from them but somehow they draw you in.

Took a whack at what life would be like for the Undertale characters once the story ends. Set in a more or less 'realistic' universe (as realistic as can be when it comes to talking skeletons and eating ramen in battle). Sans is constantly expecting and dreading resets, struggling with nihilism to make the best out of life. Intended for mature audiences, not to be taken seriously.

Once again Sans finds himself on the surface awaiting reset. He distances himself from his family- why get attached? But this time, Sans is not alone in his struggle with fear and anxiety. After taking in a little orphan monster, will he finally be able to forget his nightmares and focus on his friends and family before he looses himself, and those who are most important to him?

Repeating the same period of time over and over can really have an effect on a person, or in this case, a skeleton. TW for self harm.

Ragequittale. The anomaly has tired of trying and failing to finish the Genocide Route. They close the game, leaving the abandoned story to finish itself. Lengthy rambling about the aftermath of what I think would happen if Sans "defeated" the anomaly. Undertale belongs Toby Fox as well as numerous other people. Summary may change come future addition of chapters.

After the events of the Post-Genocide route, the monsters and Frisk were living happily on the surface until a bunch of armed men want to capture all of them. With the help of Alphys, four humans get powers to help save all the monsters in Herbal City. (PS The cover is made in MC PowerPoint 2013)

The seventh human came and went, leaving several monsters dead in their wake, including Papyrus. Undyne struggles to both deal with her own grief, and help Sans through his.

Grillby has finally had enough with this 'Kid' that keeps 'Resetting the world'. Even if he doesn't really understand the whole thing, he's DETERMINED to find out who's making Sans so upset. (Plot, Heavy Angst, Future Sansby)

One day, Sans, Sans, Sans, and Sans got together to have a party. They planned on eating quiches, playing cards, catching up, and pretty much doing nothing else. And that is literally exactly what happened. Starring Under! Sans, Edgy! Sans, Swap! Sans, Geno! Sans, Metta! Sci! Sans, After! Sans, Reaper! Sans, and eventually literally every single AU Sans I've ever heard of.

This run was different. You set out with a plan to put that skeleton in his place. When he brings you down to 0HP, you won't reset. Follow Sans as he deals with the loss of everyone he loved. Will his soul shatter when he thinks no one is watching or will something new keep him alive? Rated T to be safe.

Chara is tired of the same old same old. And Sans is just tired. Part 1 of the series This is Just Our Hell. In which Chara decides to find out just how much it takes to break the comedian, and exactly how low he can be brought down.

Papyrus is the brightest thing in Sans' life. (One-shot.)

UnderfellxUnderswap underfell sans and underswap sans change places for 2 weeks due to undyne's experiment. What will happen?

It was Alphys's birthday and her friends were throwing for her a cosplay party. Alphys was very happy with her girlfriend Undyne, and Sans had a great time with Frisk.

All AUs belong to their owners. Core Frisk and Swapped Papyrus find that other universes are breaking piece by piece, even without Error Sans' intervening. Sans, Edge, Screwball, Blaster, Geno, Outs, and Death are seven versions of Sans that assist Core Frisk and Swapped Papyrus to save the other timelines. Meanwhile, Error is teamed with Ink, Fresh, and a broken Blueberry. Hiatus!

Hey. Kid. You ever wonder how I ended up like this? Like, well, me? Heh, probably not, but I'll tell ya anyway. An AU where Sans is the main protagonist. Loosely based around the original Undertale Universe, with some modifications. Rated T for character death, depression and totally terrible puns. (R&R)

It's been at least two months since everyone was released from the underground. Getting settled, having fun, random winking, stuttering, yawning, NYEH HEH HEH'ing, etc. and bad puns is all this story is about.

I saw an undertale comic with the same name. I was filled with determination, and wrote this short one-shot.
