A mutant, Wolverine possesses animal-keen senses and reflexes and a healing factor that allows him to recover from virtually any wound. This healing ability enabled the supersoldier program Weapon X to bond the near unbreakable metal alloy adamantium to his skeletal system that includes razor-sharp retractable claws. He is also a master of hand-to-hand combat.
Wolverine joined the X-Men's "All New, All Different" roster in Giant-Size X-Men #1 (May 1975).
