Undertale AU Wiki

Welcome to the Undertale AU Wiki, the main place for documenting Undertale's AUs. If you wish to contribute, just know that it is REQUIRED for you to read the Rules and Guidelines and the Policy of the Wiki BEFORE doing so.

As this is an AU Wiki, this wiki is NOT meant for characters. The Undertale OC Wiki exists for those. This Wiki is also not meant for AUs that do not have presence anywhere else, and those should be put on the Undertale AU Ideas Wiki.

The tone of AUs.

Serious

AUs that, as opposed to Comedic AUs, actually hold a serious story and such. Just because an AU has a serious tone does not mean that it must be serious all the time, just most of the time.

Semi-Serious

AUs that have a balanced mixture of Serious and Comedic elements.

Comedic

AUs that are mostly comedic in nature. Bear in mind that a Parody can be either dark or comedic so Parodies and Comedic AUs aren't necessarily the same thing. Nevertheless, they can also be both.

Fell

AUs that feature horrible, evil, and/or murderous Monsters, but do not feature major horror elements.

Red color scheme is optional.

Monstrous

Warning: Some of these AUs contain themes that may be disturbing to some viewers. It is suggested you read the short bios of these before reading the actual AU!

Horror

Warning: Some of these AUs contain themes that may be disturbing to some viewers.

AUs with the goal of creating something scary, insane, or disturbing. Some AUs that follow the genocide route are also found here, but not all are geno-route-only. Some possible themes include suicide, drug use, alcohol use, depression, death, gore, insanity, disfigurement, pain, etc. Horror can also include Terror, and effects on psychology. This could include things like dystopias and the like.
