Matthew Michael "Matt" Murdock is a lawyer who was blinded as a young boy by a radioactive substance that fell into his eyes from a crashed vehicle. Even though he lost his sight, his other four remaining senses were heightened to superhuman levels. After mobsters killed his father, Murdock was trained by Stick to become a warrior, using his disability as an advantage to fight for the Chaste. However, Murdock's compassion for Elektra led him to be rejected by Stick. He then returned to Columbia University with Foggy Nelson to gain his law degree. Murdock dedicated his life to fighting injustice where he could find it in New York City; by day, as a lawyer with his law firm Nelson and Murdock, and by night, as a vigilante known as the Masked Man. Murdock's actions as a crime fighter eventually put him into conflict with Wilson Fisk. Murdock used his skills to expose Fisk's criminal activities and then had him arrested, with Murdock now being known as Daredevil.
