King was the former leader of the Royal Flush Gang although he still appears like the playing card for which he is named, and is immortal. He joins Lex Luthor's MLF, whose purpose is to heighten tensions between humans and metahumans, so as to reclaim control over world power. He and the other members of the MLF were double-crossed and then apprehended by Batman's Silent Cavalry.
