The man called Logan has walked many paths, not all of them the path of a hero. In the Ultimate universe, he was an assassin for the Brotherhood before joining the X-Men. While living in Japan, he suppressed his savage instincts in the name of love, until they overwhelmed him. And when he bonded with a symbiote from space, his most primal urges were unleashed. Yet he has proven himself time and again, traveling to the moon and beyond to protect his friends, his home and the Earth.
