Codename: Wolverine
Real name: Logan
Height: 5'3"
Weight: (without adamantium skeleton) 200 lbs, (with adamantium skeleton) 300 lbs
Place of Birth: Unknown (presumed to be in Canada somewhere)
Relatives: Amiko (foster-daughter), Viper (wife)
Past: Logan's past is largely unknown, mostly because many of his memories were altered and faked when he was part of the Weapon X program, the program in which he received the adamantium in the first place. Years ago, probably before the adamantium but possibly after, Logan was a government Black Ops agent along with Sabretooth, Maverick, Wraith, Silver Fox and Mastodon. Part of the program included various memory implants. As a result, it is difficult to know what events from Logan's past are real, and what are fake. Even Logan himself is uncertain about much of his life. It appears that he did have a relationship with Silver Fox that predated the program, and that he met and fought with Captain America and Natasha Romanoff, the girl who would become the Black Widow, against the Nazis in Madripoor during WWII. After fleeing the Weapon X Program, Logan was pretty feral, but he happened upon Heather and James Hudson on their honeymoon camping trip, and the two took him in. The Hudsons helped Logan reclaim his humanity, although he sometimes relapsed into his "berserker rage." Like Mac (Hudson), Logan became an operative of the Canadian government, and traveled all over the globe. He fought both the Hulk and the Wendigo, and was even slated to lead the original Alpha Flight. However, when Professor Xavier offered Wolverine the chance to join the X-Men, he took it, if only, as he said "to get out from under all the red tape." Logan became a charter member of the new team, although his rebellious nature and attraction to Jean Grey  caused a lot of tension between him and the team leader, Cyclops. Still, his skills made him a valuable asset to the X-Men, especially when he kept surprising his teammates with new ones, such as his ability to read and speak Japanese. Over time, they began to see him as less of a bestial animal-man and as more of a gruff but honorable, fun-loving guy, who would kill if he had to. On the X-Men's first visit to Japan, Logan met and fell in love with Mariko Yashida. Although their time together was short, Logan felt so strongly that he returned to Japan a few months later, only to find that Mariko's crimelord father Shingen had returned and had married her off to another minor boss, who was abusing her. Logan challenged Shingen, but Shingen cheated and goaded him into a berserker rage, proving that he was little more than a beast. Bereft of his honor and his love, Logan fell into company with Yukio, an assassin who was hired by Shingen to kill him, but who instead fell in love with her target. Yukio eventually turned on her employer, allowing Logan to kill Mariko's husband and challenge Shingen again. This time Logan killed him, and without restorting to his animal rage. Logan then proposed to Mariko, and the X-Men flew to Japan for the wedding. Unfortunately, Mastermind, who was conductinG a vendetta against the X-Men at the time, forced Mariko to break off the engagement. Although she was later freed from his control, she felt that she still could not marry Logan until her father's debts to the Yakuza (Japanese mob) had been paid. Logan remained with the X-Men, but returned to Japan with the team after the first Secret Wars. In that trip, a small dragon who had traveled with Lockheed somehow grew to monstrous size, and began wreaking havoc in Tokyo. Logan saved a woman and her child from a destroyed building, but the woman was critically injured and made Logan promise to care for her child Amiko (Akiko). Logan agreed, and became the child's foster-father, but left her with Mariko. Later, when Ogun captured Kitty Pryde and turned her into a demon ninja, Logan, who had become very close with her, and was training her in the martial arts, again traveled to Japan to rescue her. He was forced to resort to his berserker rage, but this time it was under control. Wolverine returned to the States, and was a core part of the team until the Mutant Massacre, when he began to mistrust his senses (he had smelled Jean Grey in the Alley and thought she was still dead), and took a leave of absence. Soon, however, Storm  tracked him down and asked him to lead the X-Men while she tried to get Forge to restore her powers. Logan accepted, but led the team to Dallas to find Storm when she didn't return. In the ensuing Fall of the Mutants, Wolverine led the X-Men first against Freedom Force, and then with them against the chaos unleashed by the Adversary. He died with his team in Forge's spirit spell, but was resurrected with them by Roma. When the X-Men moved to Australia, Logan went with them, but used Gateway's portals to renew his associations on Madripoor. After a while, Logan felt he needed some time alone, and left. He returned to find the team's base abandoned, and was captured by the Reavers and crucified. Luckily, Jubilee, an orphan who had snuck through one of Gateway's portals some weeks before, was able to help his escape the Reavers and get to Madripoor, where they quickly formed a close, almost father-daughter relationship. While in Madripoor, they encountered Psylocke, who had been transplanted into an Asian body and brainwashed, and freed her from the Mandarin's control. When the X-Men and the New Mutants were captured by Genoshan Magistrates and put on trial, the trio journeyed to that island to try and attempt a rescue, but were themselves captured. Logan's powers were negated by Wipeout, and the injuries he sustained while under the Reavers' tender care nearly killed him without his healing factor. After that ordeal ended and his powers were returned, Wolverine rejoined the X-Men, and eventually became a core member of the Blue Team. About this time Logan discovered the secret base where he, Sabretooth, Maverick, and the rest were brainwashed, and he encountered the failsafe robot Shiva. That little trip down memory lane made things very difficult for him, because he could no longer tell what was real. Soon after, another big blow came when Mariko was poisoned by an assassin, and Logan was forced to kill her in his arms to prevent her from dying in pain. Later, when Mastodon's anti-aging factor failed, Logan and the rest of the Weapon X subjects found out more or less which of their memories were real, and which were implants in a battle with the Psi-Borg who had brainwashed them years before. Although it took some adjustment, Logan settled back into his routine as an X-Man. Then, when Magneto returned, Wolverine was part of the strike force that invaded Avalon to stop Magnus once and for all. In the heat of battle, Logan slashed Magneto, who responded with visceral fury, and ripped every ounce of adamantium out of Logan's skeleton. Wolverine barely survived, even after Xavier shut down Magneto's mind. On the way back to Earth in the Blackbird, Wolverine hallucinated while Xavier and Jean tried to keep him telepathically alive. At death's door, Logan was turned back by a vision of the recently deceased Illyana Rasputin, and brought himself back far enough to save jean, who was falling out of the plane. A few days later, a stunning revelation shocked both Logan and the X-Men: the claws which everyone had thought were pure metal, and not a natural part of Wolverine's body, were actually bone, and were part of his mutation. In addition, the lack of adamantium for his immune system to fight appeared to enhance his mutation, and he became increasingly feral in nature. He left the X-Men to try and heal body and soul, and returned only for Scott and Jean's wedding, and to guard Sabretooth when the X-Men were fighting Legion in Israel. That night, Sabretooth got Logan all riled up, to the point where Logan, believing that Creed would try to kill his friends, plunged a claw through his brain, reducing Creed to the mentality of a child. After that incident, Logan moved out of the Mansion, believing that he was no longer in control. Some time later, the madman Genesis hoped to re-bond the adamantium to Wolverine's bones and brainwash him into a new Horseman of Death. Logan was captured and hooked into a transfer apparatus, and the procedure was underway when Cannonball, who had followed his teammate to Egypt, was discovered and severely beaten. Seeing that Sam was in trouble, Wolverine consciously accelerated his healing factor to forcibly expel the adamantium, which freed him and killed many of the Dark Riders. Logan finished the rest off by himself, and escaped into the desert. The battle exacted a heavy tool on Logan, however, as his feral nature was exacerbated by his conscious use of power, and he was left as little more than a beast, unable to speak, and guided by instinct. The X-Men came after him, and discovered him in the lair of Ozymandias, from which they rescued him. Slowly, Logan began to reclaim his humanity, so that by the time Onslaught appeared, he was in almost complete control of his faculties. Wolverine was also helped by the assassin Elektra, whose mentor Stick had exhorted her to get Logan "back on the path." At this time, Logan moved to SoHo for a while, to get back to the people, and be in a freer environment that gelled more with his feral nature. After being captured by Operation: Zero Tolerance, Logan returned to the Mansion, and tried to help some of the new X-Men adjust. When Scott and Jean left the team, Scott asked Logan to take charge of the school, which he did, for a short time, until the recent return of Professor X. Then, when Magneto resurfaced, all of Wolverine's old ferocity returned, spurred by the memory of the pain Magnus put him through, although he refused to admit it. After Joseph's  and the ceding of Genosha to Magneto, Logan really went ballistic and began plotting an assassination attempt. However, during a mission to stop Juggernaut in another dimension, Wolverine merged with Xavier's astral form and the two came to better understand each other and reach a sort of detente. After returning from the Skrull Homeworld, though, Logan kept saying that he thought Xavier was losing it. Eventually the Professor disbanded the X-Men, even rejecting Logan's offer to stay. Logan still joined up with the team that formed to help the Mannites, who were being hunted by Death III. Unfortunately, to save the Mannites, Logan sacrificed his life. His death sent shockwaves rippling through all the X-Teams, but the commotion was quickly replaced by confusion when the dead Logan was revealed to be a Skrull! Even worse, during a raid by the X-Men on a Skrull lair, they found out that Death III was really the true Logan! It is now known that Logan was captured and replaced by the Skrulls when the X-Men returned a week early from their eight-year trip back to Earth from the Skrull world. The Skrulls attacked the X-Men's ship, sending all of the mutants into stasis again as the impostor infiltrated their ranks. Wolverine was handed over to Apocalypse, who forced him to fight the adamantium-laced Sabretooth. Logan was losing until Creed told him why they were fighting: the winner would become Apocalypse's next Horseman. Logan realized that if he lost, Creed would become a destructive force that no one could ever stop, becuase he would relish his role and never fight it. So Logan pulled out all the stops and kicked Sabretooth's butt, figuring that he might eventually be able to break Apocalypse's brainwashing. The adamantium was then siphoned out of Creed's body and put back into Logan's, making him as indestructible as ever. Then, after Death spirited Mikhail Rasputin away to his master, and set a bomb in the Mansion, a group of X-Men took off after him to stop him. Pursuing him through the tunnels, they confronted and attacked him while Psylocke used Cerebro to peel away his brainwashing. Eventually they succeeded, and Death III was no more. Logan returned to the X-Men basically healed from his ordeal just in time to become human thanks to the High Evolutionary's de-mutating beam. His adamantium began to poison him, but he refused to take away his friends' chances at normal lives by complaining, so he avoided them.
Present: For the last few months, Wolverine has been visiting Japan and his foster-daughter Amiko, and also went on a solo mission to find out who was destroying Sinister's labs before rejoining the team.
