It's been a year since the Monsters retreated back into the Underground and resealed the barrier to escape the demons that roamed the surface. Asgore makes a new law banning the ruins, so Sans takes one last trip to see an old friend and bid them farewell. (One shot)

Frisk avait sauvé les monstres maintes et maintes foi. Et maintes et maintes fois, c'était la même chose. Deux personnes manquaient à l'appel: Chara et Asriel. Elle était prête à tout pour les sauver, même à commettre la pire des erreurs. Erreur qui aura de graves conséquences.(abandonnée)

Sans finally goes to the big moment with Frisk, but there is a little surprise. Rated T because of said surprise.

What will happen to Sans? What about Frisk?

Six years ago, a human child falls into the underground. Six years ago, they managed to break the barrier. Six years later, Frisk is starting to realize that had been the easy part. No matter how far they run, they can't hide from their true self. It always catches up.

Eight years have passed since Undyne and her friends escaped to the surface, but no matter how hard she tires, she just can't seem to escape her past. Desperate to move on, Undyne reaches out to Frisk for help in resolving this inner-conflict, but what will she do when it turns out that her feelings towards Frisk are no longer as simple as she thought either? FriskxUndyne

After a mysterious and catastrophic accident, Frisk has been catapulted backwards through time, before Flowey became a flower, before Toriel's and Asgore's divorce, before the downfall of the Royal family, before Chara, Frisk has found themselves in the very beginning of it all, and the only way back to their future...is the long way around, and getting there might tear them apart.

Tras terminar una de las tantas rutas pacifistas, Frisk, como de costumbre da un último recorrido al subsuelo antes de que sus amigos salgan por primera vez a la superficie, pero gracias a un momento de distracción las cosas cambiaran para siempre.

Spark, Catty's niece, spends time in the Underground, especially with Muffet, one of her best friends. :) Done as a request for Warrior fan654. :)

Chara forces Frisk into a realationship with her. Frisk is male. Chara is female. This is mature content it includes: violence, eventual smut and etc.

The second installment of my Undertale TF Series. This one is just a single person Tf. I am sorry if you don't like Tf Stories, but it's simply a thing I like write about. rated T for slight swearing and MtF, though, again, there's nothing explicitly lewd in there. I hope you enjoy the story, and be sure to check my other stories out in the future! :)

Just another genocide route... or is it?

Papcest. Underfell. Underswap. Bloodorange. Spicyhoney. Edge and Stretch always seem to get into verbal arguments. However one day they are left alone by their brothers and things begin to escalate. They are at it again... But this time seems to be different than the other times... Things are heating up between them. The only question now is will it end up good or bad?

Yeah...I wrote this story a year or so ago. It may not be the best tf story ever, but I just felt like sharing it with the world's most judgmental audience; the internet. Plus, tf stories deserve more love on this site. Hope u enjoy :). (Rated T due to some parts of the Tf, but I promise there is nothing explicitly lewd in there.) 1st part of a small series I'm making.

"What in the nine circles are you talking about? I'm not a button dude!" "Not in your universe, a universe where no form of Undertale exists. Everywhere else, you are a living act of MERCY. You help make the pacifist route in all AU's possible when the human chooses you over fighting." Ink smiled at me. "Isn't it great?" "I'm going to punch you and only feel 98% sorry."

Sometimes life sucks. For this guy, that's an understatement. So watch as walks through and underground full of Monster while showing Mercy to all... well NEARLY all.

Monsters and humans now live together in peace on the Surface thanks to Frisk, the savior of the Underground. Everything's pretty normal. Everyone's going about their daily lives... but... something doesn't feel right to Frisk. There's a lot of things left unexplained. Maybe it's best not to think about it...but...

A freak blizzard encourages Toriel and Frisk to extend their Gyftmas Eve visit at the skeleton abode, which encourages Papyrus to break out one of his favorite games! "Houses and Humans" is the Underground's take on a certain tabletop fantasy RPG. ...But what the heck does fantasy even look like in a realm where magic and monsters are are part of everyday life?

Guard Captain Undyne is used to taking new recruits under her fins—to the point that she's gotten pretty good at discerning what type of soldier her greenhorns are likely to become long before they've finished basic training! But when Undyne throws her latest student for a loop, he, in turn, throws all of her expectations right out the window. Whoopsy doopsy!

I joined a Secret Santa event in a discord server and my recipient is Perville, who was an absolute delight to write for. Here's your gift, I hope you enjoy!

(Underfell AU) You've finally made it. It was brutal, but you finally made it. Because of you, everyone's had a change of heart. They're willing to give humans another chance. And now the only one left to change their ways is the Mountain King himself. The end of your journey is at hand... right? There's... no one standing between you and the throne room... right?

Fluffy fanfics about Frisk and Asriel. These were created as little concept tests for a large scale fanfic I am going to create. All of the chapter titles are references to other things, and the names and chants of most of the spells are inspired by the Tales Series. I do not own Undertale or the Tales Series, they are owned by Toby Fox and Namco Bandai respectively.

After Betty is finally defeated the A.M.D makes a deal with the Elite Legion Of Defence (ELOD) to try and place her in an experiment called Soul Polarization (SP) to try and change her soul color from pink to gray. Even though she doesn't stay for long it sets the stage for an even darker power to make a move in a game where both humans and monster are only pawns

This story is about Frisk and his life after the underground (hence the title) this is rated T for now but might be changed to M if i write smut for it... fair warning this does contain Frisk x Asriel Yaoi

Sans has been hiding a secret for many years, one he thought he would take to his dusting day. Unfortunately for him, Papyrus is a bit too curious for his own good. One moment of curiosity lets loose many ghosts of the past that refuse to stay hidden any longer.
