6. The Beyonder

(Secret Wars/Secret Wars II, Marvel Comics)

The Beyonder is just a weird creepy child. He's like if Mr. Mxyzptlk was a terrible character.

The Beyonder is a young member of a race of reality-warping godlings who was accidentally brought to earth by the Intel, a group of evil science jerks. He watched the earth for a time, and then decided to just grab a bunch of heroes and villains, throw them into a sandbox somewhere in the cosmos, and play with them like action figures until someone won.

Of course, The Beyonder was SO DUMB, he (a REALITY-WARPING DEITY) got his powers stolen by Dr. Doom. You're practically a god! How do you lose that to a dude who blew his face off trying to get to hell? Years later, he came to earth, made himself a human body, and started creeping on New Mutants team member Boom-Boom. When he mentioned that he could destroy the universe if he felt like it, Boom-Boom freaked and went to the Avengers.

He would later kill Death, but he brought her back when everyone else got all pissed at him. Such a weirdo.
