Rocket Raccoon, originally known as 89P13, is a superhero and a major character in the Marvel Cinematic Universe. He is a thrill-seeking and wisecracking genetically altered, cybernetically enhanced raccoon who spent a majority of his life as a bounty hunter alongside his sentient tree companion, Groot. He was one of the founding members of the Guardians of the Galaxy, before he officially took over as the new leader of the team.
He is voiced by Bradley Cooper, who also portrayed Phil Wenneck in The Hangover trilogy, Faceman Peck in The A-Team, and Chris Kyle in American Sniper. The character's motion capture on set is done and is voiced as a juvenile by Sean Gunn (who also portrayed Kraglin Obfonteri), and his movement and behavior were modeled after the late Oreo.
