Powers: Sabretooth can regenerate damaged or destroyed cells at an accelerated rate, and his healing factor renders him virtually immune to poisons and most drugs. Sabretooth's superhumanly acute senses are comparable to those of certain animals; he can track a person or object by smell in a manner similar to that of a dog or wolf. Also, his claws and teeth are strong enough to rend substances as durable as bone.

Weapons: Sabretooth's skeleton has been bonded with the indestructible metal Adamantium.

History: Confined to a dark basement and subjected to other forms of psychological abuse by his father, Victor Creed survived to become the ultimate warrior. Sabretooth is driven by a psychotic need to hunt, fight and kill; previous marks have included both humans and mutants.

As a special operative for the Central Intelligence Agency, Creed frequently worked in partnership with the mysterious loner known only as Logan. Codenamed Sabretooth and Wolverine, both were products of the mysterious Weapon X project -- a government-sponsored initiative to breed the ultimate team of super-soldiers. In addition, the Weapon X scientists implanted false memories in their subjects for reasons that remain unclear. Uneasy allies at best, Creed and Logan had a falling out during a mission in Berlin; the two have been mortal enemies ever since.

Creed fathered a child with the sinister mutant shape-shifter called Mystique. Ironically, their son grew up to become a staunch anti-mutant advocate, establishing the organization known as the Friends of Humanity. Prior to his assassination, Graydon Creed even ran for president of the United States.

In Sabretooth's first recorded exploit as a costumed criminal, he kidnapped the celebrated lawyer Jeryn Hogarth. Defeated by Iron Fist, a superhuman martial artist, Sabretooth next chose to run with a pack: the Marauders, a team of assassins employed by the mysterious Mr. Sinister, an obsessed geneticist working to create the world's most powerful mutant. Helping carry out the massacre of the Morlocks, an underground community of mutant outcasts, Sabretooth again encountered Wolverine -- now a member of the X-Men, an outlaw team of mutant heroes.

In the wake of several brutal skirmishes, the X-Men finally captured Sabretooth. Always mindful of the potential for good in others, Professor Charles Xavier -- the team's mentor, as well as an enormously powerful telepath -- attempted to help Creed overcome his psychotic impulses. Infuriated upon discovering Sabretooth at Xavier's mansion, Wolverine attacked his nemesis and injured Creed's brain with one of his extensible Adamantium claws. Following his forced lobotomy, Sabretooth seemed unusually passive and peaceful. However, he recovered his true personality while pretending to remain docile and turned against the X-Men, mortally wounding the telepath Psylocke.

Sabretooth's former employer, the U.S. government, came calling once again -- conscripting him to serve with Mystique as a member of the second version of X-Factor, its team of superhuman mutant operatives. Creed was forced to wear an electronic restraining collar containing a nerve inhibitor that would administer a severe shock if he turned aggressive toward another person or attempted to remove the device. Eventually, Sabretooth succeeded in shedding the restraint. He savagely assaulted several other members of X-Factor, then escaped. Later, Sabretooth signed on with a newly revivified, government-sanctioned Weapon X program. But is he merely a pawn, or does the mutant murder machine have a plan of his own?
