Bizarro is a fictional character from the Superman universe, often portrayed as the imperfect clone of Superman. Created by Lex Luthor in various storylines, Bizarro possesses many of Superman's powers, but they often manifest in bizarre ways, such as freeze vision instead of heat vision. He speaks in reverse and often acts in a misguided attempt to be a hero. Bizarro's role in the series is as both a tragic figure and a formidable adversary, challenging Superman with his unique abilities and distorted sense of justice.
