Johnny C.

Johnny C. is an infamous mass murderer, spree killer, and serial killer who lives by the pain he sees in others. He is a SheeBookie, and a friend of some little boy named Todd - his only friend. He prefers to be called Nny - the last three letters of his first name

Personality
Johnny is a miserable, self-hating SheeBookie who only enjoys himself when he is killing people. The only time when he enjoys himself while not killing people is when he is exploding people's heads (which is technically the same thing, unbeknowst to Johnny). He doesn't seem to kill kids, though.
