Personality: Logan is a fierce, ruthless fighter struggling to keep his bestial nature in check. Although brutal and humourless with both friends and enemies, Logan has an old fashioned chivalrous streak when it comes to women. He is a loner at heart and he is much older than he looks.

Strength: 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.

Fighting Skills: Wolverine is an extremely accomplished fighter, well versed in all manner of martial arts and fighting techniques. When in control, he displays all the fighting prowess and martial honour of a modern day Samurai. But when he loses control, whether deliberately or not, his animal instincts and bestial strength more than compensate, he isn't called Wolverine for nothing.

Special Skills and 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, markmanship, and vehicles. He is also a trained expert in computers, explosives, tracking, survival, espionage and assassination techniques. He is also a student of the Japanese culture and can speak the language fluently. He also speaks Russian.

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.

He possesses retractable bone claws that are housed in his forearms, they are part of his skeleton system. 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. Due to his adamantium skeleton, his claws are 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.

Special Limitations: At times, Wolverine can fall into a wild, berserk state in combat. He prefers not to, trying to retain his human side most of the time (he does see himself as a Samurai after all, the epitomy of controlled aggresion), but will deliberately frenzy, should the need arise in a fight (such as a foe weaker against wild illogical attacks).

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.

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 have been fruitless. He is currently a member of the X-Men.
