Debuting in the Silver Age of Comic Books (1956 - c. 1970), the character has appeared in both comic books and graphic novels, and other DC Comics-related products such as animated and live-action television series, trading cards, toys, and video games.
Bizarro debuted in Superboy #68 (Oct. 1958), writer Otto Binder casting the character as a Frankenstein's monster pastiche that possessed all the powers of Superboy. Shunned for his grotesque appearance, the teen version of Bizarro only appeared in a single comic book story. An adult version, however, followed soon after: debuting in the Superman daily newspaper comic strip, featuring in Episode 105: "The Battle With Bizarro" (Strips 6147-6242 :Aug. 25, 1958 to Dec. 13, 1958). This storyline also introduced the strange speech patterns that became synonymous with the character, with all of Bizarro's comments meaning the opposite (e.g.. "bad" means "good"). The newspaper version also wore a "B" on his chest, as opposed to the distinctive "S".
