"I am Goku. I am Oozaru. To be at one with myself, I must beat you."
Goku (悟空, Gokū) 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 Goku, the longest running protagonist of Akira Toriyama's franchise, and is portrayed by Justin Chatwin.
When he is introduced, Goku is a regular teenager attending high school, and has trouble fitting in. He deals with bullies often and seems to be infatuated with the school's most popular girl, Chi Chi. Although he has been trained in the way of martial arts by his grandfather, Gohan, he opts not to fight back or abuse the skills he has been taught, partly on behalf of his struggle with believing that he can live up to his grandfather's legacy. Gohan gives the four-star Dragon Ball to Goku, shortly before being confronted by Piccolo, who kills him. After the death of his grandfather, Goku embarks on a journey with Bulma Brief, to locate the seven Dragon Balls before Piccolo, who plans to destroy the world using the artifacts.
- Dark Crane Strike, an agile martial arts technique Goku learns from his grandfather.
- Kamehameha, an energy wave technique.
- Ki Blast, the most basic form of energy wave.
- Oozaru, the ability to shapeshift into a large primate.
- "First of all, it's an honor to play Goku, because he is a very important and epic character. He is always seeing the positive side of things, does good things, and always tries to help and take care of the weak, not only pursuing his power. He is a dependable and loving man as well as a boy. So I like Goku. In preparation for the role, of course I read the original manga (all of it), in addition, I read [Journey to the West] a little, because Dragonball is based on [Journey to the West]. And during the break time of shooting, I got into Goku's character, telling jokes with other cast in search of the real communication which can be used in acting. This is the most interesting movie for me. Because I have never fought with anyone though, I trained martial arts and acrobat, and then we shot it. That's fun as well as challenging. Fighting with Eriko (Tamura), she punched me in the face, actually she intended to hit lightly, but... it was a clean hit (laugh) She said "I'm sorry!" and apologized to me, but thanks to her, we could shoot very powerful action scene. Through this work, I think I could learn a lot of things."
