Though Victor Creed's mutant healing factor and claws may resemble those of Wolverine, the comparison ends there. Sabretooth is feral, bloodthirsty, and utterly without humanity. These qualities served him well in the Weapon X program, where he and Wolverine forged their mutual hatred. Sabretooth now works for S.H.I.E.L.D., though not by choice; the bomb in his head, implanted by an unknown organization, is the only thing keeping him from killing everyone around him.
