Omnilovania: An AU Theme List by MrMayor
Fandoms: Undertale (Video Game), Deltarune (Video Game)

Summary
A huge list of AU themes that you would most likely find in an Omnilovania or similar compilation. I started the list for fun and decided to post it for others to see and use as a reference. Please don’t post it anywhere else. I do not claim to own any of the characters, AUs, or themes in my list.
Are you looking to make an AU and want to know if a song name or AU name has already been used? Or maybe you need to know which theme goes with which AU for some reason? Well then this is the list for you.

Just a dumping ground for my thoughts and ideas and theories on the game. Don’t expect regular updates. Feel free to leave theories in the comments.

Papyrus had been an ass to Dust all day until suddenly he tells him that someone is hiding in the basement and Dust rushes to find out (completeley ignoring what Nightmare, Killer, Cross, Horror, and Error think of him in that moment)
