This incarnation of Brainiac meets his final end in the "Whatever Happened to the Man of Tomorrow?" storyline that ended the Pre-"Crisis" Silver/Bronze Age Superman chronology. Lex Luthor finds Brainiac's robotic head unit, with barely any power left. He hopes to team up with the evil living program again, only to become an unwilling host body for Brainiac instead. Fighting Brainiac's control, Luthor begs a superpowered Lana Lang to kill him, who complies by breaking his neck. Luthor dies and Brainiac retains control of the body for a short time until rigor mortis sets in. "Propelled by sheer malice", Brainiac's head unit leaves Luthor's corpse and crawls a few inches before finally running out of power for good.
