Young Matt Murdock hurled himself into the path of an oncoming truck to rescue an elderly blind man about to be run down. Ironically Murdock was himself blinded when a barrel of radioactive waste fell from the truck splashing into his eyes. As a side effect, the radiation mutagenically heightened his remaining senses and activated a strange radar sense.
After his blinding, Matt was mentored by a mysterious blind man known only as 'Stick', who taught him to use his newly augmented senses and trained him in the fighting arts of Ninjitsu and Judo.
Pressed by his father, a Hells Kitchen boxer named "Battling" Jack Murdock, Matt went on to college and then law school. When Jack was killed by mobsters after refusing to throw a fight against a much younger boxer, Matt sought justice in vain. Disillusioned by the legal system, he assumed the guise of the man without fear, Daredevil.
