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 (also known as Logan), 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.

As a member of the X-Men, Wolverine has built strong relationships with many of his teammates, being close friends with Nightcrawler and Storm, with whom he also has an on-again, off-again relationship. He has also harbored feelings for Jean Grey, which has led to clashes with her husband and X-Men leader Cyclops. Across his life, Wolverine has had a son, Daken, his daughter X-23, and been a mentor to Kitty Pryde and Jubilee. His archenemy is fellow mutant and Weapon X participant Sabretooth, with whom he shares similar abilities. Alternate iterations of the character have included variations in origin, morality, and sexual orientation.
