When Beast Boy's former team, The Doom Patrol, is in trouble, the Titans must embark on a daring mission to save them. Beast Boy explains that this can only mean one thing: the Doom Patrol's greatest foes are back: The brotherhood of evil has returned.
The Doom Patrol has been saved, but the sinister Brotherhood of Evil is still on the loose. It's just like old times for Beast Boy when he finds himself back on the team for one last mission -- to stop the Brotherhood once and for all.
Evil has begun its master plan to eliminate all of the young superheroes around the globe, starting with honorary Titans Wildebeest and Hotspot. This new threat brings Robin to Morocco. But with an unknown enemy, how can anyone know whom to trust?
The Titans ask Titans East to protect the city while they go on a mission up North. Control Freak has specific weapons for the regular team. The East Coast team easily foils his first attempt, then he comes back with new challenges meant to foil the East coast team.
The Titans find Dr Light trying to increase his powers by tapping into the Aurora Borealis. But his equipment can't handle the power and he flees, and falls through a hole. The Titans chase him into a prehistoric world where they encounter Kole, a girl with the ability to change into crystal, and her companion. Dr Light wants to use Kole to tap into the Aurora Borealis.
The Titans' mission: to warn their generation's heroes of the Brain continues. Raven's assignment is to bring her three charges to a safe place. It's complicated by the fact that Mallah is after them, and her charges are only a few years old.
The Brain and his army have managed to capture or neutralize many Titans and their honorary members. Beast Boy leads the few remaining honorary members in a desperate attempt to free the captives and stop The Brain once and for all.
The Titans are back from fighting the Brotherhood of Evil. The average criminals are still rampant in the city, but Beast Boy is distracted, and abandons his teammates to pursue a girl that looks like and may even be Terra.
