Young Matthew Michael "Matt" Murdock lost his sense of sight after saving a blind old man from being hit by a truck which contained radioactive waste compound which fell in his eyes after the truck crashed. While recovering in the hospital, Matt discovered his hearing, smell, taste, and touch were amplified to superhuman degrees. He also developed a "radar sense" that formed a mental picture of his surroundings. With the help of the ninja master Stick, Matt learned how to control his new abilities and honed his skills in acrobatics and martial arts. After his father died, Matt tracked down his killers and later used his skills to fight crime and injustice in his neighborhood, Hell's Kitchen, as a lawyer by day, and as a superhero known as Daredevil at night.
