Wolverine

Wolverine is a fictional character, a superhero who appears in comic books published by Marvel Comics. Born James Howlett and commonly known as Logan, Wolverine is a mutant who possesses animal-keen senses, enhanced physical capabilities, three retracting bone claws on each hand and a healing factor that allows him to recover from virtually any wound, disease, or toxin at an accelerated rate. The healing factor also slows down his aging process, enabling him to live beyond a normal human lifespan. His powerful healing factor enabled the super soldier program Weapon X to bond the near-indestructible metal alloy adamantium to his skeleton and claws without killing him.
