In DC Comics lore, the Doom Patrol is a team of superheroes who have been outcast as freaks and misfits.
The first incarnation of the group debuted way back in 1963, and Beast Boy was an original member.
They devote their lives to protecting a society that doesn’t accept them for who they are, led by a man who may not be exactly what he seems.
Unfortunately, there’s not much else we can say about the Titans version of the Doom Patrol based on just this one image, but the odds are pretty good that the group’s appearance will have something to do with Beast Boy, who will be played by Big Hero 6’s Ryan Potter.
