Despite only being the villain for The CW’s sole remaining DC show, Superman & Lois’ Lex Luthor may be a character of even greater significance than originally thought. After several episodes of setup in the show’s third season, Superman & Lois finally unveiled its take on the Man of Steel’s greatest enemy. Rather than bring back Jon Cryer who played the character when Tyler Hoechlin’s Superman was part of the Arrowverse, the series elected to go with a whole new interpretation of the villain in the form of Michael Cudlitz.
