A college graduate falls into the Underground after she crashed her car near Mount Ebott. Being an adult, she's far more cautious than her six predecessors, therefore managing to survive her life in the Underground. Things seem to be going fairly well. That is, until a determined, corrupted child falls into the Underground... [OC!Protagonist, Fem!Frisk, Slight AU]

Esto simplemente ya era el colmo. Un hermano que lo malentiende todo a su conveniencia y el otro al que parece no importarle nada en la vida. En serio, que problemáticos son los dos. Frisk x Sans, ligero Papyrus x Frisk. One-shot. AU.

Yeah Sure

A Human has fallen into the underground after frisk with no memory, and a strange talking sword...

"Something is different this time." A Chara second person perspective of a pacifist run, after uncountable neutral ones.

Dr. W.D Gaster wasn't sure why he told 1-S and 2-P what he did. But he found himself recalling the one time he met a human. The one time his interaction with the species wasn't tainted by blood, war, anxiety or fear. A moment in time he still, to this day, doesn't understand. And wishes that he did. Inspired by Zarla-S's "Handplates" series, I present...a tender moment in time.

A young girl named Ana found a way to access other dimensions with possibilities in time. She knows she can delve back in time to try to access the memories she lost, but is it more important that helping a friend? (After the events of all play throughs of the game)

Orion once thought that he was a good friend, that he could protect his friends and family, but after Chara breaks him, and forces him to follow their plans, he's not so sure anymore. Is this all truly Chara's fault, or is it his for ever listening in the first place? (Genocide Route) [Gender neutral Frisk/Chara]

"SANS? WHAT WERE OUR PARENTS LIKE?"

So I've had a special link with a monster for as long as I can remember. He makes me laugh so I never worried about it. But when I'm tied to the fate of the underground itself that's when things really get tricky. Let's just say I won't be forgetting this anytime soon, no matter how many times we reset. (Gonna be rewritten)

When Frisk does Genocide Route to try and save Chara and Asriel, Mad Dummy and Napstablook, along with Sans, remember the RESETS and go to stop Frisk with words to get her to see that genocide isn't the way. Done as a request for Drivingmaster19.

Sans can't wait to start his first day of kindergarden! But he has one big issue, and Gaster isn't sure starting school is a very good idea...

Gem is different. She knows. Everyone else does to. One day she is chased up MT. Ebbot and falls with a dorky blond boy. Aiden's friendships are fake. He knows. Everyone else does to. One day he makes a real one. Jake made a mistake. And he knows. Everyone else does to. One day, Stone helps him forgive himself.

Time is a constant. The child is new.

What if there was an... unexpected reason to why you never hear Frisk talking? What if one little decision changed it all?A story of one betrayal causing a predetermined least, that's what people think. But don't worry, that is but a good premise for the adventure to come.(Warning for sensitive themes peppered between chapters.)

Fell becomes a fugative of the Underground when he refuses to kill his brother. Forced to fend for himself and his brother, he winds up in UnderSwap. Blue's gotten used to the monotony of everyday life in the Underground. Until he finds two injured and unconscious monsters in a field. He decides to take them in and heal them despite his brother's wishes. [EdgeBerry]

So you decided to take the chance. You couldn't let It go... but you couldn't make It stay. Maybe this is a good alternative. Definitely something new. Why not see what he has to say? Might be worth your time. [Definitely look at the author's note if you have not read Unexpected Encounter].

This is my headcanon for Undertale Multiverses. This in mind things are different than that of the canon ones. If you get triggered by stuff then please refrain from reading, YOU HAVE BEEN WARNED. Things in the once peaceful Multiverse start to get wild. Within this chaos life continues on within the multiverse. Can the next generation save the Eververse? RATED TEEN JUST IN CASE

The first step in accepting what's happened has been taken. The first of many, but the first one is done. Back among friends, back among family. Now to continue with life, now to continue without looking back! This calls for celebration! For one special human, that saved them all. However, first it has to made sure that everyone's invited, and that everyone wants to come.

Monsters lost the war, becoming enslaved to humans. And in time becoming pets or zoo attractions. Sans' keepers are trying to breed him- A new skeleton named Papyrus joins the zoo. Sans is hoping that he can get rid of this new pest. Unfortunately, Papyrus just seems to bounce back...
