Wolverine is a superhero appearing in American comic books published by Marvel Comics, often in association with the X-Men. He is a mutant with animal-keen senses, enhanced physical capabilities, a powerful regenerative ability known as a healing factor, a skeleton reinforced with the unbreakable fictional metal adamantium, and three retractable claws in each hand. In addition to the X-Men, Wolverine has been depicted as a member of X-Force, Alpha Flight, the Fantastic Four, and the Avengers. The common depiction of Wolverine is multifaceted; he is portrayed at once as a gruff loner, susceptible to animalistic “berserker rages” despite his best efforts, while simultaneously being an incredibly knowledgeable and intelligent polyglot, strategist, and martial artist, partially due to his extended lifespan and expansive lived experiences. He has been featured in comic books, films, animation, and video games.

Christopher S. Claremont is an American comic book writer and novelist, known for his 16-year stint on Uncanny X-Men from 1975 to 1991, far longer than that of any other writer, during which he is credited with developing strong female characters as well as introducing complex literary themes into superhero narratives, turning the once underachieving comic into one of Marvel's most popular series.
