The Lich (Canon)/Omniversia999

"Before there was time, before there was anything, there was nothing. And before there was nothing, there were monsters. Here is your gold star." --The Lich

Summary
Not much is known about the Lich or his past, but it is likely that he was the comet that caused the extinction of the dinosaurs.

He was "born" from the mushroom bomb, and has set his sights on destroying every form of life in the universe for an unknown reason, only to have his plans thwarted by Finn and Jake on several occasions. When he had his sights set on the Citadel, he was purified by the guardian blood and reverted into a human baby. Sweet P is the adoptive son of Tree Trunks and Pig.
