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

A human child climbs Mt. Ebott and makes a wish with her soul to live another life, only to fall into the Underground. The human known as Frizk must now learn how to live a life with monsters while also keeping their human identity a secret. A Royal Scientist Princess overworks herself to help make life better for monsters. Will the two be fated to meet?

Error has an... Hallucination? Dream? He doesn't know.

Does a murderer deserve redemption? Do they deserve a second chance? Especially when they ruined everything? It was their fault for everything bad that may have happened in more than one life? These are the thoughts of young Chara Terians Dreemurr, princess to the monster kingdom and in her assumed third life. Full Summer Inside. Squeal to One Simple World

"Long ago, two races ruled over Earth: Humans and Monsters." One race feared for their strong souls, the other for their magic, and the mages caught between them feared for both. All silently knew that war would be inevitable. The only thing that mattered was surviving it. One crimson mage understands that well, and is determined to keep herself and those she cares for alive.

A kid falls down a vast chasm into the deep, and is set upon by countless monsters eager to murder whoever falls down and claim their souls. Somehow, this child is the villain in your story.

[Horrortale AU] After their fight against Omega Flowey, Frisk left the Underground to get help and save their friends. Unfortunately, humans are not as comprehensive as monterkind and they didn't believe them. How to change their mind ? In the Underground, the situation is getting worse. Toriel and Undyne are fighting for the throne, and chaos is taking place in the Kingdom.

The power of Determination is a strength that humans have in spades. It's what let you journey through the Underground, it's what kept you going in spite of it all. It's what drove you to try and SAVE Asriel... by any and all means. But what happens when that Determination falters? What happens when Determination rots under the weight of what you've done?

Follow Uriel Dreemurr - formerly Frisk - as they live life in the Underground with their family. Making friends, dealing with bullies, helping the royal family heal, its all in a days work for the first Hybrid.

At the end of the war, monsters don't have the choice : they have to Mont Ebott for survive another day. Sans and Papyrus, forced to run away after the attack of their village, are delivered to the horror of the war without any help and this one objective. But as sons of the royal scientist, W.D Gaster, they are an easy target. Both of them start a dangerous journey.

We are taken into a universe where a lot like the Classic Universe the monsters have been trapped in Mount Ebott. The thing that has changed is that the monsters have the ability to transform into humans but have forgotten that ability and how to do it because no one has transformed since they have been trapped, all except Sans. -On and Off hiatus re-write in progress-

Frisk spends time with their family. With Asgore visiting the family spends the whole day together.

Undertale is a 2015 indie game owned by Royal Sciences LLC and the game's developer Toby Fox. Undertale is a game loved by many, due to its meaningful themes and storylines, which is why both I and Isa decided to create this book. Undertale Wisteria is both the plan of a future fan game and a story.

For Monsterkind, the Surface represented freedom. For Frisk, it's a return to some uncomfortable realities. It all began with a simple wish. When that wish faded, Frisk tried to move on. Except, 'moving on' was not so simple. Emerging from the Underground had put them in a worldwide spotlight. From an unknown child, they had become an icon of great value.

This is the story of two 15-year-old girls forced to share a body and a soul. Once, they were destined to save or destroy the world. Now? They're just trying to live a "normal" life. (Focused on Frisk and Chara being forced to share a body post-cannon specifically the timeline is neutrals- last-second aborted genocide-true pacifist-fanfic events)

Desde que se vieron por primera vez; cuando sus memorias cursaron por sus ojos, al ver todas las atrocidades que hizo, Betty supo que Frisk no merecía salvación... pero vio tanto las cosas buenas, como malas. Eligió ser bueno, cariñoso, amoroso, amable; una contradicción andante, que, de algún modo, hacía que el matarlo y odiarlo fuera más difícil de lo que debería.

Ever since the first time they saw each other; when his memories coursed through her mind, seeing all the atrocities he did, Betty knew Frisk wasn't worth saving... but not just the bad things, the good things as well. He chose to be good, to be loving, to be kind; a walking contradiction, that somehow, made her goal of both hating and killing him seem way harder than it should be.

A Multiverse Phenomenon drags Nightmare to a place that should be unreachable. Yet it changes the course of this Multiverse irrevocably.

Golden Quiche / Crimson Keeper specific universe. A 'Chronographer' is a title reserved for those with the power and authority to observe, manage, and record the annals of spacetime. They're the primary historians of this world.

Undertale AU. After countless resets, Frisk resets one last time to save everyone. But that doesn't mean everything is forgotten. Frisk is still haunted by their actions. Eventually, everyone starts ing things they shouldn't. Actions have consequences. What you do, can't be taken back. Even after resetting.

They have known each other for a long time. They fought often, they each lost and won an equal amount of times. It was a routine of theirs. Destroying Alternate Universe, fixing them, destroy, fix, again and again. There seems to be no stop. No one would dare get in their way, no one dared to help nor did any others tried to reason with them. And this story is no exceptions...

Something happens to stop the normal flow of a Genocide run. An anomaly appears...but maybe it's not the one you think. *Trigger warnings: there might be some violence/threats/feeling trapped and self-harm at some point

Sequel to "Hope Among Monsters". It seems it wasn't Rose's time after all, but can a mysterious person help her, Chara, and Asriel return to their family so that the monsters and all their children can get the best happy ending? Done as a request for dream1990. :)

Amplification. The power to amplify... anything. including itself. ... let's see how this goes. not sure on the rating so I'll just leave it on the minimum until I write something to raise it up. kind of fast paced. I hate stories that just drag on and on. Minor system.
