The New Teen Titans, Vol. 2 Annual

Jericho reads up about a case from the Titans’ past. A team of super-powered beings which traverses the universe helping worlds who need them, The Vanguard arrived on Earth, battling and attempting to capture Superman. Before they could abduct the Man of Steel, the New Teen ‘Titans intervened, but quickly realized that this could not be the real Superman. As it turned out, the Superman that was captured was a robot. The combined might of the Titans and the Vanguard proved enough to overcome Brainiac and his re-channeled super-energy. They rescued Superman after Brainiac’s own energy was scattered across the cosmos. The Titans and the Man of Steel turned to Earth and The Vanguard continued Its travels.
