I need a name for this AU...help

Chara, ruler of the underground?

This AU is where it is. Chara killed Asgore and took over the throne. Frisk? They were forced to be Chara's servant, granted immortality to serve her for all eternity. She keeps a close eye on Frisk to make sure they don't reset and ruin the new "perfect society" Chara has now created. Sans is the only one confident enough to fight against Chara with his knowledge of the timelines. The others? They are too afraid to go against her. She did kill Asgore in one hit. She must be very powerful.

Any subject that gets caught going against her is sentenced to death in some of the most gruesome, painful, unbearable, twisted ways. They all die a slow death where Chara insures that their final sight is her.

Sans manages to escape her every time and is considered an outlaw in the underground. He hides in the ruins with Toriel, who is the only other monster willing to do something, but has never had the courage to fight her own demonic daughter.

I may make a story for this? Most likely.
