At the Marvel Panel at Emerald City Comicon 2011, Marvel Big Wig Brian Michael Bendis took a moment for our favorite evolved mammal and member of the Guardians of the Galaxy: Rocket Raccoon
In response to a fan request to see Rocket Raccoon in the future, Bendis replied, "I wouldn't be surprised if Rocket Raccoon turned up in the 'Ultimate Spiderman' cartoon -- that's the level of nerdiness that we're at."

By the way, "BRAKKA" is a classic sound blurb for a big gun.
Click on the pic and read the dialog. It's classic Rocket.
