Sabretooth

Sabretooth is just one of the several man-made killers created by the Weapon-X project. Once an ally of Wolverine, he is now one of the most vicious of the X-Men's foes. He has an incredible healing factor that makes him immune to most drugs and poisons, and he has greater endurance than most human beings. With his fearsome claws, sharp teeth and innate savagery, Sabretooth has a bloodlust that is rivaled only by his hate for Wolverine!
