Distortiontale is an average AU, where everyone was once happy.That is, until the Chara merged souls with Frisk. They were both alive at the time, Chara having a black, HATE soul. Frisk still had a DETERMINATION soul. Chara had control of the body, and had basically killed Frisk. Sans, failing to help his friends, killed Chara/Frisk, and absorbed the HATE/DETERMINATION soul, giving him 20 HP instead of 1 HP. He also owned a special locket, that looked like a monster soul was the heart on the chain. It gave him the ability to survive 20 hits, no matter what.
