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... no matter what the cost.

The Brotherhood of 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 who to trust?

The final game has begun. While the Titans are spread out throughout the globe on one last mission, Brotherhood mastermind, the Brain, makes his move. Robin has a strategy of his own, but as all the villains begin taking down all the superheroes all at once, will it be enough to save his friends?

All seems lost for young heroes across the globe: they have been spread far and wide, their lines of communication have been severed, and one by one, the Brotherhood of Evil takes them down. But as The Brain claims his victory is assured, one brave hero manages to slip thorough the Brotherhood of Evil's grasp: Beast Boy.
