Lex Luthor will make his Supergirl debut in the fifteenth episode of the show's fourth season (titled "O Brother, Where Art Thou?") when the villain attempts to enlist Lena in a plan which will see him "stop at nothing to get her on board, even if that means leveraging the life of one of her friends."
Jon Cryer is, of course, playing Lex and a first look at him behind bars has now been revealed!
It's certainly easy enough to picture him as one of Superman's greatest foes and executive producer Jessica Queller promises that he's portraying a comic accurate version of Lex. "The character is not that dissimilar to what we’ve seen in canon. He just [has] a sparkle in his eye and is smarter than everybody in the room and 12 steps ahead of everyone, and just a large, delicious villain."
"He’s the biggest supervillain we’ve had on the show, and his plans will kind of touch every character and impact the entire season moving forward once he arrives."
