Logan Howlett - Wolverine

Logan appears to be the ultimate personification of manliness and masculinity. While he appears to be perpetually angry, he is a rather complicated man, due to his violent and mysterious past. He has very little patience for those around him, and this quality adds to his gruff demeanor and solo attitude. Indeed, Logan prefers to be alone due to him disliking and distrusting the company of others. Despite his disgruntled nature, he has a very dry sense of humor, constantly insulting others and giving them demeaning nicknames. Logan does not hesitate to harm or kill and seems not to harbor any true remorse or guilt over any violent actions he has done in the past, with the exception of Jean Grey in the erased timeline. His past has, in fact, emotionally scarred and forced him to make himself numb to the pain and suffering he has endured, from his childhood trauma to his several lifetimes as a soldier in many of the most violent wars in modern history. His is therefore less inclined to show mercy towards his opponents, anyone else that attacks him, or those who he thinks deserve it, such as when he tried to kill Noburo Mori since he was corrupt and took part in Mariko's kidnapping to be paid a fortune.

Despite his willingness to use violence, he is still a moral person who does not do so needlessly, nor does he attack innocent people. While he is described as cynical and pessimistic, Logan is nonetheless a good person and will always stand up for those who can't defend themselves, or at the very least be willing to avenge them, as such as his killing of Agent Zero for attacking him and killing the elderly couple that sheltered him. While hiding in a well from the Nagasaki nuclear bombing, he was not fazed by the destruction going on outside since he could do nothing about it, but was still willing to save Ichirō Yashida when he had the chance to, unable to leave the man to die. However, when Yashida proved himself to be evil and repeatedly tried killing Logan to gain his healing as Silver Samurai, Logan tore the suit open, pulling the wires that kept Yashida alive, before stabbing his chest and dropped him off a cliff to his death in a rage. Logan has grown some restraint and perhaps mercy over the years presumably because of his prolonged exposure to the X-Men. Although he has no restraint or regret for unleashing his animal side on those deserving of such violence, he does not show cruelty to those who do not deserve it, for example, he shows mercy to the the Pentagon guards by non-lethally incapacitating them while attempting to free Magneto with Charles and Beast.

Although officially an X-Man, Logan prefers to be alone. He has a deep distrust and an inherent lack of respect for people, regardless of whether they are both human and mutant, having seen nearly 200 years of violence, prejudice, and war. This attitude also stems from having people he trusted betray him, such as Kayla, and his brother, Victor. However, the true reason for Logan's wanting to be alone is due to the fact that so many people tend to die around him, such as friends and loved ones. He also shows signs of self loathing for the violent life he has lived and the pain he has endured.

Logan is extremely loyal to and protective over the few who can gain his trust and respect. He is completely ready to sacrifice his life if it will save someone he loves, and will stop at nothing to protect his friends and family. Despite his blunt personality, Logan has made many friends with the X-Men, but most notably Rogue, becoming almost a father figure to her, after realizing that both of them are outcasts. His is also one of Xavier's most trusted allies, with Xavier even having a mentor role to Logan. He grew attached to Charles to the point of breaking down when he was disintegrated by Dark Phoenix. He is also greatly attached to Mariko Yashida, having found a chance of happiness with her, to the point of risking his life to defend her while his healing factor was disabled, fight an army of Black Clan ninjas, and even torture a member of the Yakuza to find her.

Logan is a man of vice; he loves to drink alcohol and smoke cigars, knowing that neither can effect his health due to his powers. He is also an adamant motorcycle rider and has shown to have a hatred/fear of flying in planes.

His most famous traits are his temper and attitude. Logan seems constantly angry and has a very short temper. Though he is capable of deep thought, he has said himself that he has an animalistic side to his personality. This side of him is feral and primal, causing him to become instinctual and go berserk, especially in combat. It is caused by his animalistic mutation and triggered by rage, fear, frustration, great annoyance, general distress, or pain. It results in him becoming highly aggressive and mindlessly brutal, similar to an animal, as he is prone to roar with rage in most of these cases. In some cases, it is this brute-like side of Logan that make it easy for him kill and harm without hesitation.

After the events of 2029, having long since lost all of his loved ones (excluding Charles), combined with his gradually weakening body, Logan's outlook on life has become bleak at best. More hostile than ever, Logan cares little for helping others and seeks only to find a small measure of personal peace by becoming a drifter on the sea. With his healing powers so weak that he is no longer immune to toxins, he has taken solace in drinking. However, upon learning of his estranged biological daughter/clone, Laura, and a series of events that would help her, Wolverine ultimately regains his compassion and hope from years ago.
