The half-hour comedy follows three kids who are drafted into a secret world of crime fighting after Mike Fukanaga (Ryan Potter), an average high school student, discovers he is descended from a long line of ninjas. Takei plays Mike's recently deceased grandfather; he appears as an interactive hologram to guide and train the team of "Supah Ninjas" along the way.
"The grandfather has the serious task of instructing the next generation of ninjas, but he also has a lot of funny moments and I find that a refreshing take on the traditional teacher-student relationship," Takei said.
Carlos Knight co-stars as best friend Owen and Gracie Dzienny is Mike's crush, Amanda.
A preview of Supah Ninjas will air Monday, Jan. 17 at 9/8c.
