Wolverine (real name James Logan Howlett) is a fictional character in the Marvel Comics comic book universe. He made his first appearance as a villain fighting The Incredible Hulk. He was known as "Weapon X" back then. Since then, he has had a long and varied career, most notably working with The X-Men.
Wolverine has both natural and man-made abilities. His natural abilities include his heightened senses and his rapid healing ability which makes him very difficult to kill. His man-made ability is the Adamantium in his body, which makes up his claws and laces his skeleton. As a result, his retractable claws can slice through almost anything, and his bones are almost unbreakable.
Wolverine is renowned for his gruffness and sheer savagery. He's one of the few X-Men who has no compunctions about killing and has been frequently at odds with his fellow teammates. He also has a dark past that involves the Canadian government and some of the X-Men's biggest foes.
He was also (at one point in time) in love with Jean Gray.
His voice was provided by Cathal J. Dodd[?] in the X-Men animated television series, and in a series of video games through the 1990s. In the animated television series X-Men: Evolution[?], his voice was provided by Scott McNeil[?]. In the movies, he was played by Hugh Jackman[?]. In the movie tie-in computer game X2: Wolverine's Revenge, his voice was provided by Mark Hamill.
The University of Michigan's sports teams are called the Wolverines.
