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.
