The final 10-episode season picks up from the dramatic cliffhanger ending of season 3, which saw Clark battling with Lex Luthor's monstrous creation Doomsday. Said to be a loose adaptation of the Death of Superman comic, early reviews have described the opening episodes of this final run as both "dark" and "heartbreaking."

Superman and Lois Season 4 has already made use of some of Superman‘s greatest enemies. However, the appearance of Lex Luthor and Doomsday may just be the beginning. An off-hand remark by Lex Luthor may tease the arrival of yet another classic DC Comics villain.

Superman & Lois recently premiered their final installment, Season 4, which answered a long-time question: Is Superman alive? In retrospect, the answer to the ongoing CW show is No, Superman is not alive.
