Teen Titans, Vol. 3 #25 (2005)

The Insiders - Part Three
[continued from Outsiders #24] The truth is revealed: Lex Luthor slipped programming into Superboy during his creation, and now can control him with a phrase. His plan is to kill the Teen Titans, reasoning that burying their coffins will destroy Superman and the Justice League's heroes in a way nothing else can. This will free Luthor up to cure cancer, or end famine, or any number of other world changing things he can't do while Superman lives. Or so he says. With a tremendous exertion of magical lightning, Wonder Girl breaks Superboy free of his twisted father's influence, but this is fleeting. And before she can try again, Indigo (now Brainiac 8) intends to kill Wonder Girl, as she already killed her predecessor Donna Troy, by reprogramming a Superman robot!
