Two of voice actor Josh Keaton’s major roles right now couldn’t be any more different from one another: on the one hand, you have space cop and pilot Hal Jordan over in Green Lantern: The Animated Series, and on the other, you have his regular role as Jack, the teenage sidekick to the Earthbound Autobots in Transformers: Prime.
