An android is created on the planet Argon with all the powers of the Justice League members, who is able to utilize the powers of two members at a time, and correspondingly takes a half-and-half appearance of those heroes (i.e., half-Flash / half-J'onn J'onzz); But when he falls in love with that planet's queen, is rejected, and is rocketed to Earth, the android goes on a rampage that even the Flash and the Martian Manhunter seem unable to halt.
