S2, E8: When Rev hacks into Tech's computer, he and Lexi play what they believe is a simulated video war game. Instead, it turns out to be Tech's new defense system. Without realizing, Lexi has launched an attack against an unknown target that turns out to be MELVIN THE MARTIAN, who offers a deal with the Loonatics: He'll give them his word that he won't destroy Acmetropolis, and they will give him Lexi!
