As Night Lantern, he was the leader of the Justice Titans. He and the rest of the team was called to apprehend Batman and Superman. They initially complied, believing them behind a recent crime spree, but they quickly became allies after Superman rescued a bystander that was almost harmed during their battle. With their help, the J.T.s were able to deduce Terranado as an undercover agent; however, this realization came too late, as Terra led the Brotherhood of Injustice into the Justice Tower.
