Daredevil is a superhero appearing in American comic books published by Marvel Comics. Created by writer-editor Stan Lee and artist Bill Everett, with some input from Jack Kirby, the character first appeared in Daredevil #1 (April 1964).

Daredevil is the alias of Matthew Michael Murdock, a lawyer from Hell's Kitchen who was blinded in childhood in a chemical accident that enhanced his other senses. After his father Jack is killed by gangsters, Matt hones his physical abilities and superhuman senses under his mentor, the blind and mysterious Stick, becoming an expert martial artist. Eventually, in ironic contrast to his Catholic upbringing and beliefs, Matt dons a devil-like costume and takes up a dual life of fighting against the criminal underworld in New York City. This puts him in conflict with many super-villains, including his arch-enemies Bullseye and the Kingpin. He also becomes a skilled and respected lawyer who forms a law firm with Franklin Foggy Nelson, his best friend and college roommate. He establishes a long relationship with co-worker Karen Page, who experiences many hardships before her eventual murder by Bullseye. Daredevil also has a relationship with Elektra Natchios, a fearsome ninja assassin who is murdered by Bullseye before being resurrected.
