Wolverine

Wolverine is a superhero appearing in American comic books published by Marvel Comics. The character first appeared in the comic book The Incredible Hulk #180 (1974) and is best known as a member of the superhero team the X-Men. Wolverine is the alias of James Howlett, a mutant born in Canada in the late 19th century. He possesses a range of superpowers including highly advanced self-healing abilities, a significantly prolonged lifespan, animal-keen senses, and retractable claws. His skeleton is reinforced with the unbreakable fictional metal adamantium, which he acquired after becoming an unwilling test subject in the Weapon X super soldier program. Wolverine is commonly depicted as a gruff loner susceptible to animalistic "berserker rages" who struggles to reconcile his humanity with his wild nature.
