UPDATE: It has now been announced that Trevor Devall will supply the voice of Rocket Raccoon in the animated series, having already portrayed the gun-toting Rocket in ‘The Return of the Guardians of the Galaxy’ episode of Ultimate Spider-Man.
If they’re sticking with the cast from that episode, expect Chris Cox as Star-Lord, Nika Futterman as Gamora and David Sobolov as Drax the Destroyer.
