Teen Titans Go! (2013)

S1E12 Gorilla

Beast Boy transforms into a boisterous gorilla and stubbornly refuses to revert, much to Robin's frustration. This gorilla version of Beast Boy seizes control of the Titans, creating disorder as he prevents a girl from using his monkey bars, engages in battles with crocodiles, and liberates gorillas from the zoo. Meanwhile, Cyborg steps in to mentor Robin on how to assert himself as an alpha male, aiming to reclaim his position as leader of the Teen Titans.
