Batzarro (Wayne Bruce) is a supervillain in the DC Comics Universe. He is a twisted doppelgänger of Batman, in the same vein as Bizarro, the similar doppelganger to Superman. While a Bizarro version of Batman had first appeared in pre-Crisis continuity in World's Finest Comics #156 (March 1966), his first appearance in post-Crisis continuity occurred in Superman/Batman #20 (June 2005), which was written by Jeph Loeb.
