Wolverine is a fictional Canadian superhero who appears in comic books published by Marvel Comics. Born James Howlett and commonly known as Logan, Wolverine is a mutant, possessing animal-keen senses, enhanced physical capabilities, retracting bone claws, and a healing factor that allows him to quickly recover from virtually any wound, disease or toxin, also enabling him to live beyond a normal human lifespan. This healing ability enabled the supersoldier program Weapon X to bond the near indestructible metal alloy adamantium to his skeleton and claws without killing him. He is most often depicted as a member of the X-Men.
