Wolverine

Wolverine (real name James "Logan" Howlett) is a Marvel Comics character who is a mutant super-hero and a member of the X-Men and the Avengers.

Background
Wolverine was born James Howlett in northern Alberta, Canada, during the late 1880s, purportedly to rich farm owners John and Elizabeth Howlett, though he is actually the illegitimate son of the Howletts' groundskeeper, Thomas Logan. After Thomas is thrown off the Howletts' property for an attempted rape perpetrated by his other son, named simply Dog, he returns to the Howlett manor and kills John Howlett. In retaliation, young James kills Thomas with bone claws that emerge from the back of his hands, as his mutation manifests. He flees with his childhood companion, Rose, and grows into manhood on a mining colony in the Yukon, adopting the name "Logan". When Logan accidentally kills Rose with his claws, he flees the colony and lives in the wilderness among wolves, until he is captured and placed in a circus. Saul Creed, brother of Victor Creed, frees Logan, but after he betrays Logan and Clara Creed to Nathaniel Essex, Logan drowns Creed in Essex's potion. Logan returns to civilization, residing with the Blackfoot people. Following the death of his Blackfoot lover, Silver Fox, at the hands of Victor Creed, now known as Sabretooth, he is ushered into the Canadian military during World War I. Logan spends time in Madripoor before settling in Japan, where he marries Itsu and has a son, Daken. Logan is unaware of his son for many years.

During World War II, Logan teams up with Captain America and continues a career as a mercenary. He serves with the 1st Canadian Parachute Battalion during D-Day, and later with the CIA before being recruited by Team X, a black ops unit. As a member of Team X, Logan is given false memory implants. Eventually breaking free of this mental control, he joins the Canadian Defence Ministry. Logan is subsequently kidnapped by the Weapon X program, where he remains captive and experimented on, until he escapes. It is during his imprisonment by Weapon X that he has adamantium forcibly fused onto his bones. James and Heather Hudson help him recover his humanity, and Logan begins work as an intelligence operative for the Canadian government's Department H. He becomes Wolverine, one of Canada's first superheroes. In his first mission, he is dispatched to stop the destruction caused by a brawl between the Hulk and the Wendigo.

Later, Professor Charles Xavier recruits Wolverine to a new iteration of his superhero-mutant team, the X-Men.

Personality
Logan appears to be on his wild and volatile side always growling, while on his other side, he shows to be attracted to redheads because they remind him of Rose, as he spotted Mary Jane and attempted to flirt with her in Peter's body but failed, and in the comics he was shown to have feelings for his teammate, Jean Grey, but could not bring himself to come between her and Cyclops, the man she loved.

From this wild side also sports a berserker-like rage which he uses as his battle cry to strike fear into his enemies. His fierce attitude often makes other heroes like Spider-Man feel uneasy around him.

He has a habit of calling people "Bub". Logan also easily gets annoyed to the point of being short-tempered

Physical Appearance
In Ultimate Spider-Man, Wolverine wears a yellow suit with brown accents; his boots, gloves, mask, and upper chest of his costume are all colored brown. He wears a red belt with a gold buckle. The rims of his eyepiece and boots are pointed upward, and his eyes are white with no pupils. Wolverine's mask is only open at his mouth, where beard stubble is visible. He is also shown to have elongated canine fangs. His appearance resembles the appearance of his Earth-616 counterpart, but with the uniform used in the 1980s comics (including the Secret Wars crossover), designed by John Byrne.

His modern suit has a lighter shade of yellow with dark blue accents instead of brown. The suit is sleeveless and has stripes on the sides of it. The eyepiece is also much more narrow than the Ultimate counterpart. His belt also has an "X" on it to show his affiliation with the X-Men.

 * Immortality: Wolverine's healing factor has also kept him in the physical prime of a normal man and he has been that way for years and he will never age as a result. According to Wolverine himself, the only way to permanently kill him, is to cut off his head from his body, however due to his bones being infused with adamantium; this would be extremely difficult, if not impossible to achieve as only the cartilage between his vertebrae is unprotected by Adamantium. Moreover, it may not even work, as Deadpool has a similar healing factor and can survive having his head cut off.

Wolverine later showed up in New York City, saving Spider-Man from the dinosaurs by killing them. He became the new member of the New Avengers and helped stop Kang from taking over the world.

Wolverine then aided the Avengers to fight the Heralds of Galactus. He battled against the herald Stardust along with the Thing, Wasp, and the Human Torch. He also helped destroy the machine used for devouring the Earth. He later helped the Avengers successfully send Galactus into the Negative Zone. After the fight, he and the other heroes left, leaving the Avengers with civilians who hailed them as Earth's mightiest heroes.

Wolverine arrived in New York to fight other civilians who were mind-controlled by Mesmero. Wolverine believed that Spider-Man was the cause of the civilian's bizarre behavior. Wolverine accidentally cured the bizarre behavior of them and tracked Mesmero was the real cause. Wolverine threatened Mesmero to release the civilians from his control. Wolverine was approached by Nick Fury and got in a discussion with Spider-Man. Before Wolverine left he was remarked by Spider-Man, Wolverine got upset and tried to harm him but Fury stopped him.

The next day, Mesmero switched Peter's and Wolverine's minds. Wolverine was called by Peter where he found out that he switched bodies with Spider-Man. When Sabretooth barged in Logan's apartment, Wolverine explained who he was and told him that he would come over there. Peter persuaded him to stay in school. Wolverine got in touch with his (Parker's) Spider-sense and was angry against Peter's team, beaten Flash Thompson and flirted with Mary Jane Watson. When Peter arrived at school followed by Sabretooth, he told Wolverine to put on his Spider-Man costume. Wolverine objected at first, but, but did so eventually. Together, Wolverine and Spider-Man fought Sabretooth and defeated him.

In the Helicarrier where Mesmero was held, Wolverine advised Peter to focus his powers to control his claws, Spider-Man threatened Mesmero and he putted them back into their bodies.
