Character History
Rocket was recovered by alien scientists and brought to the planet Halfworld, where he was genetically and cybernetically enhanced so that he was given sentient levels of intelligence. However, years of abuse and repetitive genetic rewrite caused him to develop a vain and chaotic personality, driving him into becoming a gun slinging mercenary.
