Oozaru (大猿, Ōzaru; Literally meaning "Great Monkey") is a fictional character in the Dragon Ball franchise. He makes his debut in the 2009 film Dragonball: Evolution, the first of a purported three installments of 20th Century Fox's live-action film series. He is an adaptation of the Great Ape, a transformation assumed by members of the Saiyan race in Akira Toriyama's franchise, and is portrayed by Justin Chatwin. Unlike in Toriyama's original franchise, the transformation in Dragonball: Evolution is triggered by a solar eclipse rather than staring into a full moon, and its user does not require the tail of a Saiyan to transform. Its size is also dramatically reduced from the original series.
Roshi describes Oozaru as one of two gods who, along with Piccolo, nearly destroyed the Earth two-thousand years prior. However, Piccolo and his disciple Oozaru's reign ended after seven mystics used the Mafūba to seal Piccolo inside of a container. While Oozaru's whereabouts after this are uncertain, a prophecy asserts that he will return during a solar eclipse, and as Piccolo reveals, during this eclipse Goku, who "traveled by meteor to hide among the vermin until [his] eighteenth birthday," will be reborn as Oozaru. When Piccolo's explanation becomes true, Goku, as Oozaru, attacks Bulma, Yamcha, and then Roshi before coming to his senses and regressing to normal. Goku accepts that Oozaru is inside him, and a battle between he and Piccolo ensues.
Oozaru makes his first playable appearance in a Dragon Ball video game spin-off in Dragonball the Movie. In the game, Oozaru fights against Roshi before fighting against Goku in a space-like environment in Goku's mind.
