Wolverine is a fictional character, a superhero that appears in comic books published by Marvel Comics.
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.Depictions of the speed and extent of injury to which Wolverine can heal vary. Originally, this was portrayed as accelerated healing of minor wounds, but writers have steadily increased this ability over the years. After several years, Wolverine's healing factor was depicted as healing severe wounds within a matter of days or hours. Other writers went on to increase Wolverine's healing factor to the point that it could fully regenerate nearly any damaged or destroyed bodily tissues within seconds. Among the more extreme depictions of Wolverine's healing factor include fully healing after being caught near the center of an atomic explosion and the total regeneration of his soft body tissue, within a matter of minutes, after having it incinerated from his skeleton. It has been stated in the Xavier Protocols, a series of profiles created by Xavier that lists the strengths and weaknesses of the X-Men, that Wolverine's healing factor is increased to "incredible levels" and theorizes that the only way to stop him is to decapitate him and remove his head from the vicinity of his body. If an object composed of carbonadium is inserted and remains lodged within his body, his healing powers are slowed dramatically though they are not fully suppressed. His healing factor also dramatically slows his aging process. Despite being born in the late 1800s, he has the appearance and vitality of a man in his physical prime. Though he now has all of his memories, his healing abilities can provide increased recovery from psychological trauma by suppressing memories in which he experiences profound duress.
Wolverine's senses of sight, smell, and hearing are all superhumanly acute. He can see with perfect clarity at greater distances than an ordinary human, even in near-total darkness. His hearing is enhanced in a similar manner, allowing him to both hear sounds ordinary humans can't and also hear to greater distances. Wolverine is able to use his sense of smell to track targets by scent, even if the scent has been eroded somewhat over time by natural factors. This sense also allows him to identify shapeshifting mutants despite other forms they may take.Due to high level psionic shields implanted by Professor Charles Xavier, Wolverine's mind is highly resistant to telepathic assault and probing. Wolverine's mind also possesses what he refers to as "psychic scar tissue" created by so many traumatic events over the course of his life. It acts as a type of natural defense, even against a telepath as powerful as EMMA FROST
Wolverine is frequently depicted as a gruff loner, often taking leave from the X-Men to deal with personal issues or problems. He is often irreverent and rebellious towards authority figures, though he is a reliable ally and capable leader. He has been a mentor and father figure to several younger women, especially Jubilee and Kitty Pryde, and has had romantic relationships with numerous women (most notably Mariko Yashida), as well as a mutual but unrequited attraction to Jean Grey, leading to jealous run-ins with her boyfriend (later husband), Scott Summers.Though he is a skilled combatant, Wolverine is frequently depicted entering combat situations in which he willingly allows himself to sustain injuries that would permanently cripple or kill those without sufficiently enhanced healing capabilities. In such situations, he relies on his healing factor and adamantium skeleton to handle the damage. He is also depicted on occasion deliberately injuring himself or allowing himself to be injured for varying reasons including freeing himself from capture, intimidation, strategy, or simply indulging his feral nature. Despite having an almost superhuman pain tolerance, he does not enjoy being hurt and sometimes has to work himself up for situations where extreme pain is certain
