Strength Level:
While Wolverine may be of an advanced age, he possesses the normal human strength of a man in his prime with his height and build who engages in intensive regular exercise. While possessing the adamantium skeleton, Wolverine's strength was increased to the human maximum, making him capable of lifting (pressing) 800 lbs.

Abilities:
Due to his extensive training as a CIA operative, a Samurai, and as a member of the Weapon X program, Wolverine is a master of multiple forms of martial arts, weapons, and vehicles. He is also a trained expert in computers, explosives, and assassination techniques.

Known Superhuman Powers:
Wolverine is a mutant with a number of enhancements to his physiology.

Wolverine possesses heightened senses, making him capable of seeing things at a maximum distance greater than that of a normal human. His hearing is enhanced in a similar manner, and he is able to recognize people and objects by scent, even if that person or object is hidden. Logan can use these enhanced senses to track anyone, with an impressive degree of success.

Wolverine possesses retractable bone claws that are housed in his forearms. At will Wolverine can release these claws through his skin between the knuckles on each hand. The skin between the knuckles tears and bleeds, but bleeding is quickly halted by his healing factor. The claws are naturally sharp and tougher than that of normal human bone structure. This allows Wolverine to be able to cut through most types of flesh and natural materials. (Note: While Wolverine possessed his adamantium skeleton, his claws were able to cut through almost any material without any fear of damage to the claws.)

Lastly, Wolverine possesses an accelerated healing factor based on his physiology. While most normal humans heal injuries over a long period of time, Wolverine's healing factor speeds up that natural process. Wolverine's natural healing has been advanced to the point where he can heal extensive injuries (such as broken limbs) in a matter of hours to days. This factor gives him a higher resistance to poisons and toxins, and he can recover from almost any injury. The more extensive the injury, the longer the healing time will be.

Wolverine is not immortal, however. If the injuries are extensive enough, especially if they result in the loss of vital organs, large amounts of blood, and/or loss of physical form (such as having flesh burned away by fire or acid), Logan can die.

Wolverine, again due to his healing factor, has an enhanced resistance to disease, as well as an extended life span. Despite Wolverine's chronological age, he is still as healthy and physically fit as a man in his prime.

Until his first recorded encounter with the Hulk as an agent of Canada's Department H, the past of the man known as Wolverine remains shrouded in mystery.

Logan possesses memories of being a Samurai in Japan, a mercenary operative for the Central Intelligence Agency, and a "wild man" in the Canadian wilderness. Due to the extensive memory implants given to Logan through the Weapon X program, any and all of these memories are suspect. Logan has at least one memory of meeting Captain America in World War II which was verified as true. It is possible that Logan's healing factor grants him an extended life span and has granted him the physical condition of a man in his prime, despite his age.

Sometime after World War II, Logan was taken by a group of scientists led by Dr. Cornelius as part of the Weapon X program. Cornelius was hired to perfect and use a technique that would bond the indestructible element adamantium to human bone cells. Logan's skeleton was bonded to the adamantium, and he was indoctrinated into the Weapon X assassin program.

After his encounter with the Hulk, Wolverine was conscripted by Department H to join and lead Alpha Flight, Canada's government-run super team. During his leadership of Alpha Flight, Wolverine was approached by Professor Charles Xavier, who was looking for mutants to help his students, the X-Men, escape from the island-being known as Krakoa, which had captured them. Wolverine left Alpha Flight to accompany Xavier and rescue the captured X-Men. After Krakoa was defeated, Wolverine decided to stay with the X-Men, for reasons which included that he had fallen for the X-Man known as Marvel Girl (see Phoenix).

Logan remained with the X-Men for quite some time, at one time being their field commander, and encountering adversaries such as Proteus, Magneto, the Brotherhood of Evil Mutants, the Brood, the Reavers, demons from the dimension of Limbo, the Marauders, the Morlocks, and even Dracula on one occasion.

After his encounter with the mutant assassin Omega Red, Logan began to question the memories he possessed, but his searches to find his true identity and memories proved fruitless.

During an encounter with the mutant Magneto on his space station called Avalon, Wolverine attempted to defeat Magneto using the claws presumably given to him by the Weapon X project. Magneto retaliated, using his powers of the magnetic field to tear the adamantium out of Wolverine's skeleton, causing extensive injuries. These injuries shorted out Wolverine's healing factor for a time, and Logan also discovered that the claws that he believed a result of the Weapon X project were in fact a natural mutation. The claws he now possesses are bone, and a natural part of his skeletal structure.

As a result of his injuries, Logan left the X-Men for a time, returning after he was asked by Xavier, who also asked the mutant Cable, to rescue the X-Men in Tibet, where they were captured during the Phalanx invasion.

Recently, Logan was kidnapped by Tyler Dayspring, calling himself Genesis, who wanted to make Wolverine one of his new Horsemen. Genesis had acquired adamantium by destroying the body of the mercenary known as Cyber, and had planned to recreate the bonding process used on Logan years ago. This time, however, Logan's body rejected the adamantium, and he regressed for a time to a feral-like state.

Logan regained his lucidity, rejoined the X-Men, and supervised the team while Cyclops and Phoenix are on leave.

For a period of six months, preceding the final battle with Apocalypse, Logan was kidnapped and replaced with a shapeshifting Skrull who completely assumed his identity, fooling even those closest to him.

During that period of time, Apocalypse transformed Logan into one of his Four Horsemen, Death. The adamantium was re-laced into his bones.

It took the combined efforts of Nightcrawler, Kitty Pryde, Jubilee, Psylocke, and Angel, to break Apocalypse's mental hold on Logan, but they managed to succeed.

Logan once again found himself brainwashed, this time by Hydra, who turned him into a killing machine. SHIELD managed to capture him, and are currently trying to de-program his mind.
