The son of a prize fighter named Battlin' Jack, Matt grew up in the relative poverty of Hell's Kitchen   As a boy, Matt witnessed a man about to be hit by a truck, and pushed him out of the way, just as the truck crashed and spilled its cargo, extremely toxic chemicals, into his face.  He awoke in the hospital, now blind from the toxins, and learned that his other senses were amplified as a result of his loss of sight. He was able to see by a radar-like sense using natural sounds around him, giving him ultimate confidence in his surroundings.   He would later become a lawyer, opening a law firm with Foggy Nelson, and taking on the mantle of 'Daredevil' after his father's death, in order to protect the citizens of Hell's Kitchen and bring justice to the streets as well as the courtroom.
