After constantly being rewound back to when he'd first fell to the Underground at the end of netrual run, 13 year old Frisk hears a voice in his head that he'd never heard Before and began to find his body being controlled by another force of some type, forcing him to do Genocide.

Will continue in Determination's Destination.

Undertale and Characters seen in the games belong to Toby Fox.

New characters NOT in Deltarune or Undertale games belong to me. 

While based off of the cannon game, it is still an AU of sorts, so don't expect 100% accuracy to the game's dialogue and story. This is just my own spin of things, so don't expect things to be perfect.

[Undertale (2015) originally by Toby Fox. This story is an AU, and is written to be mostly understandable to non-fans.] TL;DR AU Chara & Frisk slow-burn enemies to friends. [Content warning throughout for references to child abuse/neglect and suicidal thoughts.] It's an unseasonably cold morning in May when runaway foster kid FRISK finally decides to give in to the siren's song of the mountain that's been haunting them since they hitchhiked to the small town of Ebott. They're expecting a quick end to a long, miserable story, but what they find at the bottom of the pit they tumble into is far from anything they could have predicted. Thrown into a world of magic and monsters, they realize things here are nothing like the world they left behind. And, of course, there's the voice in their head. That part's definitely new. Newly awoken from a death that was supposed to be final, CHARA, misanthropic former Princet of Monsterkind, must contend with the fact that not only is it awake again, but it's stuck with a human, of all things, as its host. All it wants is to finally complete its plan to set its family free--but the owner of the head it's stuck in seems intent on getting in the way. At this point, closure seems impossible. But there's only so much two kids sharing a body can avoid each other. As the two settle into an awkward alliance, each with their own motivations to reach the King of All Monsters, it becomes apparent that they will need to use their unique bond to their advantage. The fate of this world has long been set in stone. But with enough determination, even mountains can be moved. Undertale "Tags": --Narrachara --Nuanced Chara --Nuanced Frisk --Chara & Frisk-centric --Not romance-centric --No player, but there not being a player changes the story. (Frisk filling the role of the Player is the driving force of changes in this AU.) --Frisk is not a Dreemurr sibling. [STATUS: 2/6 acts completed, 150k words so far. Placeholder cover.]

There are some things you just can't take back. No matter how many times you reset. After breaking free of Chara's grip, Frisk decides to do one final reset before defeating Sans or proceeding to the throne room. But some memories last longer than others, and broken trust isn't easy to repair. Female, aged-up Frisk. Starts out canon and then diverges. Eventual Sans x Frisk. Undertale was created by Toby Fox. I do not own Undertale, nor any of the characters. Some violent action scenes. Cover art is by amazing artists at http://www.zerochan.net/Undertale,Fanart and http://www.zerochan.net/Chara+(Undertale),Fanart
