ROCKET RACCOON - #1 (1985 - CONDITION VF)
Rocket and his animal companions were genetically manipulated animals with human level intelligence and a bipedal body construction. They were created to be caretakers of the inmates (or "loonies") on the verdant side of halfworld. Rocket was a guard who protected the colony against various threats.
Rocket and his friends ultimately cured the inmates of their mental illnesses and then took off into space for their own adventures.
