Ostarius is a large colossi "judge" whom was created by JD to protect the Hidden Lands. He is a bit of a hot head, getting angry very easily, so it's not surprising that he's already ticked off whenarrives in his territory. Much like or , he too uses a huge weapon against his enemies. His weapon of choice is a huge mallet, hence the reason of him resembling a Colossi judge.
His first appearance nearly destroys BB when he slams his mallet down where the kid once stood. Ostarius tried time and time again to kill BB but not working. At one point he whacks BB Argentinosaurus form hard, the kid now realizing doing the same strategy isn't gonna work. The colossi keeps chasing him until he ends up in a holed area, where he ends up doing a colossi version of "whack-a-mole" for awhile until BB becomes a gorilla and smashes his head, causing him to fall backwards and lose his chakra orb.
It was thanks to Ostiarius that Beast Boy was able to gain his ultimate form to fight Raviente.
