Bill Cipher forever! All hail the demon dorito! He always wanted to rule the multiverse and I think that a universe filled with chaos and destruction without any human pests would be great!
"Remember, reality is an illusion, the universe is a hologram, buy gold, BYE!" "You two wait here; I've got some children I need to make into corpses." "Name's Bill, but you can call me your lord and master for all of eternity!"
