Dr. Michael Twoyoungmen was a surgeon who found that modern science was insufficient to accomplish everything he wished to do, and so he turned to mysticism that his grandfather told him about.
Born with super-human senses and the power to heal from almost any wound, Wolverine was captured by a secret Canadian organization and given an unbreakable skeleton and claws. Treated like an animal, it took years for him to control himself. Now, he's a premiere member of both the X-Men and the Avengers.
