The Terrifics #21 (Year of the Villains)
Bizarro and the Terribles have invaded Earth-0 with a mission: turn back the clock. Armed with a time machine given to him by Lex Luthor, the one and only Man of YesterdayTM is determined to reverse progress in the Multiverse to a simpler time, a stupider time you might say. A bizarre time. So who's going to stop this regression transgression? The Terrifics, that's who!
