Wolverine (the most over used character in comic books) has taken X-Force one step further. Brining in the most violent "heroes" in the Marvel Universe. He has formed the Defenders. Killing the bad guys to save the world. Too bad he's the most wanted man in the world. Hunted by Avengers, X-Men and every government agency in the world. Sometimes you have to be the ultimate bad guy to be a hero.
