The Joker

He killed Batman's parents. So without him there would not be a Batman. Batman also created the Joker.

the joker is hte best hands down. no one beats him. read the dark knight series and then get back to me on who is the nubmer one villain.

the joker is the best super villain he's a psychotic killer

The Joker is the ONLY villain on this list (that I know of) that has NO purpose. It's this trait that makes him the scariest. He isn't trying to destroy Batman, or destroy the world, or get lots of money or anything. He just finds it funny when people suffer. He has found ways to destroy Batman and Bruce Wayne, and I would gaurantee he could take on any hero out there, and probably win.

The sickest, most twisted, villian in the comic universe...

The best Villain of all times.

he is cool and freaky

the joker is insane, evil, crazy mastermind and doesn't care who he hurts

HE IS PURE CRAZY/EVIL/GROTESQUE/DISTURBING. AAAAAAAAHHHH HA HA HA HA HA!!!!!!!
