VIDEO: Bradley Cooper's Raccoon Superhero Gets an Origin Story in 'Guardians of the Galaxy Volume 3' Trailer

The universe’s least likely group of superheroes strap in for one last adventure in Marvel’s “Guardians of the Galaxy Volume 3,” arriving in May.

Set to Spacehog’s classic alternative track “In the Meantime,” the official trailer (above) sees Peter Quill (Chris Pratt) and his crew — Groot (Vin Diesel), Drax (Dave Bautista), Nebula (Karen Gillan), Mantis (Pom Klementieff), and Rocket (Bradley Cooper) — encounter a variety of the galaxy’s most deadly threats, from supervillain Adam Warlock (Will Poulter) to their former ally Gamora (Zoe Saldaña). The clip also highlights the origin stories of a few crew members, including Cooper’s character Rocket, a genetically modified raccoon with a penchant for big guns and crude comments.

“We have been running our whole lives,” Pratt’s character says at one point.

“Pete, I’m done running,” Cooper’s raccoon responds.

Written and directed once again by James Gunn, “Guardians of the Galaxy Volume 3” co-stars franchise veterans Elizabeth Debicki, Sean Gunn, and Sylvester Stallone as well as newcomer Maria Bakalova (“Borat Subsequent Moviefilm”), who voices Cosmo the Space Dog. While voice acting may sound simple to some, Cooper told Howard it took two years to record all his lines for the first “Guardians of the Galaxy” film.
