Rocket Raccoon is a four-issue comic book limited series that was published in 1985 and featuring the eponymous character.
The series took place in a half-world where Rocket and his anthropomorphic allies fought killer clowns with lethal juggling balls, deadly unicycles, and speak in a stilted language full of alliteration and rhyme.
In November 2008, the Rocket Raccoon limited series was reprinted in the Annihilation Classic books.
Rocket and his friends ultimately cured the inmates of their mental illnesses and then took off into space for their own adventures.
Marvel Age #25 (April 1985): had a preview of the mini-series and featured Rocket Raccoon on the cover.
