Wolverine was the code-name of a mutant Human, given name Logan, who existed on Earth in another reality. He was born with a mutant ability to heal nearly instantly, and was the subject of an experiment that bio-chemically bonded a metal, adamantium, to his skeletal structure. He became good friends with Commander Worf of the USS Enterprise-E, who respected his prowess as a warrior. In 2374 he helped defeat the Draa'kon in orbit of Xhaldia before returning to his home reality. His enemies include Sabretooth. (TNG novel: Planet X)
