Superman & Lois Season 4‘s final episode has premiered. The stakes were high as it resumed the final showdown between Superman and the mighty Doomsday. However, in a shocking turn of events, the monster ended up killing himself for the Man of Steel.

All El is about to break loose in Smallville as Superman & Lois literally smashes into its series finale tonight. And in TV Insider’s exclusive clip from the hour, “It Went By So Fast,” it becomes clear that our Man of Steel is gonna need some backup if there is any hope of ending the series in one piece.

The character has been adapted by Zack Snyder in his DCEU film Batman v Superman: Dawn of Justice. However, the monster seen in the film was not the real Doomsday, who was found in the depths of Krypton and was only bestowed feelings of hate. In the film, he was the result of experimentation by Lex Luthor on the corpse of General Zod.
