Official Bio

Black Lion pilot and voice of Shiro, Josh is no stranger to heroing. He has voiced young Hercules in the Disney Animated film Hercules, Spider-Man in The Spectacular Spider-Man, Green Lantern Hal-Jordan in Green Lantern: The Animated Series and the Flash in DC Girls to name a few.

Voice Roles

Initially, Keaton auditioned for Shiro, Keith, and Lance, but did not get any roles until he was called back a second time 6 months later after the first voice actor for Shiro did not fit.[2] Keaton did not believe he would not be replaced, even after recording some episodes to see how his voice meshed with the rest of the cast, because no one gave him a clear answer on whether or not he earned the role of voicing Shiro. It was not until they were doing press releases that Keaton felt secured on the series cast.[2]

Keaton feels he can connect with Shiro thanks to being a father and sharing the responsibility of looking out for the life of another being, because Shiro must act as leader of the Paladins and protect the lives of Team Voltron.[2] Growing older and having kids has made Keaton gain patience that he feels he can mirror in Shiro, and he thinks of Shiro's method of helping the team work together rather than force anyone to cooperate or stay reflects the way Keaton "leads" his family.[2]


  • Keaton is a fan of Voltron: Defender of the Universe and has a Black Lion toy from childhood; it is the only Lion from that generation he has and ever got to play with, so the Black Lion is his favorite.[2]
  • Keaton acknowledges Shiro's fan nickname of "Space Dad" and has adopted it as his own moniker.
