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.

This article contains information that is from a completed AU. All parts of the story have been released and are readable at any time.

For the sequel, see Errortale.

Aftertale is an AU where Chara has full control of Frisk's body and keeps RESETTing the timeline and doing the genocide route for what Chara calls "research". After thousands of resets, Sans feels as if the only way to beat Chara is through injecting determination in himself just before Chara reaches the Judgement Hall.

After 536 tries, Chara was finally able to hit Sans. As he was dying, Sans walks off and notices he had the ability to CONTINUE, RESET and SAVE. Sans had also the ability to teleport to the SAVE screen where he RESET his timeline.

Sans (now nicknamed Geno because of the Genocide route) cannot leave the SAVE screen or he will turn to dust. Chara then gains so much determination that Frisk permanently loses control of their body and joins Geno in the SAVE screen.
