Lessee…
- Texas Battle as Carey Fuller: A high school bully. He is an original character created for the film.
- Luis Arrieta as Weaver: A classmate and friend of Goku. He is an original character created for the film.[11][unreliable source?]
- Shavon Kirksey as Emi: One of Goku and Weaver's friends and classmates. She is another original character created just for the film.
Yup, all real. Very minor roles though.
- Randall Duk Kim as Grandpa Gohan: The adoptive father and grandfather of Goku who teaches Goku everything he knows about martial arts.
Real. Only thing I know him from is as the Keymaker in the Matrix, but he seems good for the role. But we haven't seen any pics of him in costume, and not much info about him otherwise. Makes sense, since he apparently dies early on in the movie.
- Christopher Sabat as Shenron: The wish granting dragon summoned when all seven of the Dragon Balls are gathered.[2]
Don't know where this came from (Wiki's the first I've seen of it too). But it would be cool if it's true. If they gotta get someone to do Shenlong's voice, they might as well make it the guy who's been voicing him for about 10 years. (Fixed :P)
- Ernie Hudson as Master Mutaito: Master Roshi's former sensei and the one who sealed Lord Piccolo away for centuries.
Also true. Straight from the man himself's mouth.
