Warning: Spoilers for Superman & Lois Season 3, episode 5 below!Superman & Lois is honoring the widely varying origin stories of one of the Man of Steel's long-standing villains on the show. Superman & Lois season 3 picks up with Clark Kent (Tyler Hoechlin) facing a new collection of villains, including Bruno Mannheim (Chad L. Coleman), his villainous cabal known as Intergang, and the mysterious Onomatopeia. Meanwhile, the ending of season 3's episode "Head On" sets up the return of another villain from Superman's past.
Specifically, the final scene of "Head On" sees Bruno Mannheim in possession of the body of the deceased Bizarro Superman. The scene implies that Bizarro is likely to be resurrected through some kind of laboratory experimentation by Mannheim and Intergang in order to pit him against Superman again. With this and Bizarro's origin story in Superman & Lois season 2, the show is going to great lengths to incorporate every facet of Bizarro's complex background into his role on the show.
