Joshua Luis Weiner, better known as Josh Keaton, is the voice actor of Shiro. Keaton is not only a voice actor, but is also an actor and singer. He is known for his roles as Young Hercules from Disney's Hercules, Jack Darby from Transformers Prime, and Peter Parker from The Spectacular Spider-Man.

Voice Roles

Initially, Keaton auditioned for Shiro, Keith, and Lance, but did not get any roles until he was called back a second time sixth months later after the first voice actor for Shiro did not fit.[1] 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.[1]

Keaton is a fan of Defender of the Universe, having watched it as a kid and rewatched it as an adult, and loves how Legendary Defender pays homage to both the original Voltron show and Beast King GoLion.[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.[1] 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.[1]


  • Keaton 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.[1]
  • Keaton also has a Gladiator Voltron toy that was given to him by his father, who received it from one of his students while teaching English as second language.[1]
  • Keaton acknowledges Shiro's fan nickname of "Space Dad" and has adopted it as his own moniker.
