EARTH: Edison Rex

A world where Edison Rex, the greatest supervillain on Earth, succeeds in killing the planet's greatest superhero, Valiant, only to find himself compelled to take up the role of protector in Valiant's absence. Rex applies the same formidable intellect and ruthlessness he used as a villain to defending humanity, assisted by his android companion Eli. Valiant and Edison are clearly alternate version of DC's Superman and Lex Luthor.
