Comments: Little is known of his past, save that it was fraught with pain and loss. Long ago he trained as a samurai in Japan; later he became Weapon X, an 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 is blessed with animal-keen senses that enable him to track people and objects with an impressive degree of success. In addition, his accelerated healing factor allows him to survive wounds that would prove fatal to most humans and mutants.
