Daredevil, The Man Without Fear!, the son of a boxer Matt Murdock grew up poor in the rough neighbourhood known as Hell’s Kitchen. His father constantly pushed him to study instead of playing with his friends. Which led them to taunt him giving him the nickname Daredevil. Unbeknownst to his father Matt would secretly train in his dad’s basement gym.
One day, Matt spotted a blind man as he was about to be hit by a truck, without a moments thought he pushed him out of the way but the truck crashed and spilt its cargo of extremely toxic chemicals into his face.
He awoke in the hospital blind from the toxins and learned that his other senses were amplified as a result of his loss of sight and was able to see by a radar-like sense using natural sounds around him, giving him ultimate confidence in his surroundings. He met a blind martial arts master named Stick, who taught him to hone his senses and trained him in martial arts among other skills such as free running, meditation and marksmanship.
