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 Titans manage to find and free the Doom Patrol, largely due to Beast Boy's participation, but his willingness to save his friends has enabled the Brotherhood of Evil to claim "the most devastating power in the cosmos", endangering the entire planet, and possibly beyond, which Mento blames on Beast Boy for his disobedience.
