Drax

Drax is an evil Kryptonian and a former prisoner of the Phantom Zone around the era of the Legion of Superheroes, when a younger version of Superman accidentally released Drax from his prison the malicious alien went on a spiteful rampage designed purely to cause havoc, he was suggested at being criminally insane and refered to himself as evil (though this may of been the result of brainwashing from an early age).

He is strongly suggested at being either the son or clone of Zod and like Zod is a formidable and dark mirror to the "Man of Steel" - having all of his powers but using them solely for cruelty.
