Bizarro is the imperfect duplicate and antagonist of Superman, who made his first appearance in Superboy #68 (1958). There have been many versions of Bizarros after his debut. Pre-Crisis, a scientist accidentally used a duplicator ray on Superman, which created the flawed copy of him. One Post-Crisis origin was that Lex Luthor ordered the science division of LexCorp to create a clone of Superman but the clone was flawed and escapes. Another Bizarro was created by The Joker who had stolen Mr. Mxyzptlk's powers, made to be the Joker's version of Superman. All versions of Bizarros have the abilities of Superman, though some have Superman's 'inverted powers' such as freeze vision and heat breath.
