Wolverine

Wolverine is the X-Men's greatest fighter! A master of hand-to-hand combat, Wolverine also has a fearsome secret weapon -- razor sharp retractable adamantium claws that can slice through anything. Wolverine also has an adamantium reinforced skeleton and a mutant healing ability that lets him recover from wounds in minutes. Nobody, not even his fellow X-Men, knows anything about his past. All they know is that in battle, Wolverine is unstoppable!
