Sans/Abysstale, New Undertale Fanon AU Wiki

Abyss Sans is from the AU Abysstale made by Meta-kaz on deviantart. In the story Abysstale, the AU was completely destroyed. When he got an emergency call from Undyne (an attack in a city), he got into a very powerful state. He woke up in MTT vacation house. His brother Papyrus was badly damaged in battle, and was in healing. Abyss!Mettaton, Abyss!Alphys and Abyss Sans were the only one still alive. ( Papyrus seems like he's in a coma, and that does not exactly count as alive) For safety, Alphys
