Little is known of his past. Long ago, he trained as a samurai in Japan; later, he became Weapon X, and operative for the Canadian government. Today, Logan is an X-Man - using his animal-keen senses, healing factor and razor-sharp claws to help protect a world that fears and hates mutants! Wolverine's senses enable him to track people and objects with an impressive degree of success. His accelerated healing factor allows him to survive wounds that would prove fatal to most humans and mutants. Wolverine's skeleton has been bonded with the indestructible metal Adamantium. Also, he possesses Adamantium-laced, retractable claws housed in his forearms. At will, he can release them through the skin on the back of each hand.
