9. Conduit

Kenny Braverman was born in a snow-trapped car in Smallville, Kansas. On that night, a Kryptonian rocket ship containing a baby passed overhead and irradiated the infant.

He had occasional health issues, but Kenny grew up to be quite a young lad, even though that Clark Kent kid always beat him in high school sports. But Kenny slowly began to resent Clark, and was seemingly driven insane by jealousy. At this point, his powers kicked in, and Kenny discovered his own mastery of electricity and technology. He used it to build a suit, and when he discovered that his old rival Clark Kent was secretly Superman, he decided to go off and kill all of Clark's friends and family.

Superman saved Pete Ross, Lana Lang, and his parents. He eventually fought Braverman, who overloaded and died. Poor Kenny.

I always liked him, because the dude is pretty much just a whiny internet nerd whose internet nerdiness became his superpower. And I'm not gonna lie, it's pretty satisfying to watch Superman beat up a glorified internet commenter.
