Bizarro #1, the weird yet funny Superman doppelganger from Htrae (Bizarro World), uses his duplicator ray to create Bizarro versions of Wonder Woman, Firestorm and Cyborg. These "opposite clones" are then called upon to protect Bizarro World from its many enemies. Unfortunately, the prankish Mr. Mxyzptlk plans to harness the powers of the three Bizarro superheroes in order to wreak havoc upon the earth, in an endless series of nasty pranks and practical jokes specially designed to drive everyone as crazy as HE is! Until the Real Wonder Woman uses the duplicator ray on Mr. Mxyzptlk to create Mr. Kltpzyxm, causing the Bizarro Super Powers team to go back to Bizarro World and stop him, and making Mr. Mxyzptlk accidentally say his name backwards and go back to the 5th dimension.
