Wolverine

Wolverine is a mutant with a number of both natural and artificial improvements to his physiology. His primary mutant power is an accelerated healing process, typically referred to as his mutant healing factor, that regenerates damaged or destroyed areas of his body far beyond the capabilities of an ordinary human. This power facilitated the artificial improvements he was subjected to under the Weapon X program, in which his skeleton was reinforced with the nearly-indestructible metal adamantium.
