James Howlett, better known by his alias Logan or by his super-heroic identity Wolverine, is an anti-hero appearing in American comic books published by Marvel Comics, first appearing in Incredible Hulk #180; he has also appeared in multiple TV series, and in the X-Men films produced by 20th Century Fox. A deadly mutant, Wolverine possesses animal-keen senses, enhanced physical capabilities (a healing factor in particular), and retractable claws in his knuckles; coated with Adamantium, the strongest metal in the world, the claws are capable of slashing through almost anything. A loner by nature, Wolverine was recruited by Professor X to serve the X-Men superhero team in their missions to build better relations with ordinary humans and to protect the public from dangerous mutants, including the powerful Magneto. While he has had personal difficulties with the team, Wolverine managed to lead the X-Men on multiple occasions. He appears in Disney vs. Comics as one of the prominent heroes who lead the hero forces into battle against the villains.
