"Ernie Hudson has recently been cast in the film as a sort of “Altar boy who helps Goku and friends in their journey.” It’s very likely he will be cast as Kami, the good half of Piccolo and the guardian of earth, or Mr. Popo, Kami’s assistant.
There is also a very good chance that he has been cast as “Sifu Norris,” which is very likely a codename for Kami (or they might have changed Kami’s name.)
MOVIE-MADE CHARACTERS OR CODE-NAMES
Weaver is Goku’s school friend. It has been said his role is very short in the film, though could be more important if there are sequels. There is a likely possibility that Weaver is the code name or replacement for Krillin, Goku’s martial arts friend.
Texas Battle (Carey Fuller), Shirvon Kirksey (Emi), and Richard Blake (Agundus) will have very short roles in the film. Shirvon will be Chi-Chi’s school friend, and Texas will be a school bully. That’s all we really know about these casting additions so far."
