Freak is a bizarre creature who makes his debut as a minor character in the episode "Booty Scooty".
Deep inside the stranded island where the Titans Tower is, Robin locked away Freak, an unexplainable, hideous "freak" of nature in a dark cell, the reason being that he was just disgusting and weird. When the Titans came upon him after looking for treasure, they started insulting him because of his ungratefulness. Robin had gone through the trouble of buying the most expensive chains, giving him a single sock puppet program to watch on TV, and food *barely* out of reach.
But Beast Boy felt sorry for the Freak, and he offered him friendship and a delicious turnip. Freak happily ate it up, but grew angry when Beastie ran out of food for him. He broke loose from his bonds and preceded to chase the Titans throughout the caves.
After running into Freak multiple times throughout the pirate caverns, the Titans were ejected from the cave. Back at the Tower, where they decided to just sell the map for money, Freak reappeared. Beast Boy was welcoming of his friend, but Cyborg reminded him of the initiation dance... Freak reluctantly started doing the Booty Scooty Dance to prove himself, and Beast Boy loved it.
The Titans later visited Freak, who was still residing in the cave with chains on his arms and legs and entertaining himself by watching puppet shows, after Robin lost his butt. Beast Boy was pleased to see Freak again even though Freak couldn't adapt into the society proven by how he made a chaos in Beast Boy's room last time he stayed in the tower. He then volunteered to help the Titans search for Robin's lost butt, until he fell into a spiky pit. However, he somehow managed to survive and assisted the Titans to escape from the falling boulders by using his butt to slow down a boulder from crushing them. He was last seen leaving the cave by sailing on a boat made out of butts.
