Powers: Wolverine is blessed with animal-keen senses that enable him to track people and objects with an impressive degree of success. In addition, his accelerated healing factor allows him to survive wounds that would prove fatal to most humans and mutants.

Until his first recorded encounter with the green-skinned behemoth called the Hulk as an agent of Canada's Department H, Wolverine's past remains shrouded in mystery. Due to extensive memory implants, even his own recollections are suspect: Was he a samurai in Japan? A mercenary operative for the Central Intelligence Agency? A "wild man" living off the Canadian wilderness? At least one of Logan's earlier memories -- meeting Captain America, the star-spangled Super-Soldier, during World War II -- has been verified as true. It's possible his healing factor affords him an extended life span and has granted him the physical condition of a man in his prime, despite his age.

Some time after World War II, Logan was drafted into the Canadian government's Weapon X project by a group of scientists who had been hired to perfect and implement a technique that would graft the indestructible metal Adamantium to human bone cells. The Adamantium was bonded with Logan's skeleton during a procedure he survived thanks only to his accelerated healing factor; he was indoctrinated into the program as an assassin, codename Wolverine.
