Daredevil

Matthew Michael "Matt" Murdock, also known as Daredevil, is one of the major characters from the Marvel comics.

As a child, Matt Murdock was blinded by radioactive waste while trying to save an elderly stranger about to get hit by a truck carrying the dangerous material. In turn, his other senses were heightened to superhuman sharpness and he gained a form of "radar sense". By day, he is a successful trial lawyer; but by night, he guards Hell's Kitchen as Daredevil: the Man Without Fear.

Personality
Daredevil was a morally righteous individual with a strong sense of law and justice. This also influenced him to become a lawyer. Daredevil objected to total violence and preferred to keep his enemies alive and thus defeated them rather than killed them; however, Daredevil did have a dark side, and would not hesitate to badly injure foes under certain circumstances, often when he was under a period of stress.

As a young lad, Matthew was instilled with high morals by his father, Jack, who encouraged the boy to focus on his studies and not to play or fight with other kids. Matt took his father's lessons to heart and was thought to be an exemplary of good nature by figures of authority. Despite all this Matt did have a mischievous side and one occasion stole the baton of a police officer. Matt was incredibly selfless which led to him performing many heroic deeds in his life, such as saving a blind man from an oncoming truck, which lead to Matt's blindness. In the early stages of his disability Matt suffered increased frustration, feelings of helplessness, and self-loathing; however, due to training under Stick, Matt managed to conquer the struggles which boosted his confidence and he eventually developed a fearless attitude.

As Daredevil, he has displayed a heavy sense of humor and snarky remarks in various life-threatening situations, especially early in his career. Throughout his long tenure, however, his various trials have made Daredevil a grimmer and less light-hearted vigilante. Despite all his great virtues, Daredevil is not without his flaws, and has shown extreme ruthlessness especially when those close to him have been threatened or targeted by his enemies. An example of this would be willing to torture Ox for information on his boss that had targeted his wife. Matt also suffered from severe clinical depression, which has led him to indulge himself in self-destructive tendencies.

Abilities
Although blind, Daredevil's remaining four senses function with high levels of superhuman accuracy and sensitivity, giving him abilities far beyond the limits of a sighted person.

He also has a great ability to remember smells, so he can identify people by smell alone.
 * Lie Detection - Daredevil can tell whether a person is lying by listening to changes in their heartbeat or by smelling their sweat when they are under pressure.
