Beast Boy

Beast Boy was a former member of the Doom Patrol, and one of the five founding members of the Teen Titans and Justice League.

He was originally the youngest member of the Doom Patrol. However, Mento's harsh discipline and less-than-encouraging attitude finally alienated him from his surrogate family, and he struck out on his own. Looking for a new place to live, he came to Jump City, where he encountered Robin, Starfire, Raven, and Cyborg and aided them in liberating Starfire from her Gordanian captors. Afterward, the five formed a new team on their own, the Teen Titans.
