Daredevil (aka Matthew Michael Murdock/ Matt Murdock) first appeared in Daredevil #1 (1964), created bul Stan Lee and Bill Everett.
Murdock's origin leads to Hell's Kitchen in New York City, where he was blinded by a radioactive substance that falls from an oncoming vehicle while pushing a man to safety from the oncoming truck. While he no longer can see, the radioactive exposure heightens his remaining senses beyond normal human ability and gives him a "radar sense".
As an adult, Matt Murdock became a lawyer and is commonly known as the Man Without Fear, when he is donning his crimefighting gear.
It was rumoured that Jack Kirby was the original artist who designed the Daredevil's debut costume in Yellow, Black & Red. The story tells that Murdock had donned in those colours of his late father's boxing outfit, while setting off to seek out his killers.
The blinded hero's outfit was redesigned into today's crimson red in the iconic issue 7, where he had one fearsome fight with Namor, the submariner.
Unknown to many, Spiderman is one of the few hero friends he has, whom he would occassionally confide in, team up to fight crime, and remain good friend till this very day.
However, there was a time, when a letter from Spidey unintentionally exposed Daredevil's secret identity, compelling him to adopt a third identity as his twin brother Mike Murdock, whose carefree, wisecracking personality much more closely resembled that of the Daredevil guise than the stern, studious, and emotionally withdrawn Matt Murdock did. The "Mike Murdock" scheme was used to highlight the character's quasi-multiple personality disorder. So much so, at one point the character wonders whether Matt or Mike/Daredevil "is the real me".
Following this, let's explore some of the more notable characters revolving the colourful life of this Devil from Hell's Kitchen:
In 1970, Matt Murdock moved to San Francisco. There, he met Black Widow (aka Natalia Alianovna "Natasha" Romanova), and shortly after started dating her for almost 4 years, from 1971 to 1975. Seriously.
In issue 124, the Russian assassin left the heartbroken Murdock, with the latter returning to Hell's Kitchen.
Subsequently, he found his new love interest in a livelier & party-loving Heather Glenn, whom he parted ways eventually due to her alcoholic problems. The poor girl dated the alcoholic Tony Stark briefly after that, and later committed suicide.
Approaching the 80s, Murdock's martial art sensei (Stick) found his way back into his life, so did Murdock's ex-girlfriend Elektra Natchios.
She was depicted as the love of his life for Murdock, but he eventually failed to rekindle the relationship with her, due to her violent personality.
She was eventually killed by an arch-enemy of Daredevil, Bullseye.
Towards the end of the 80s, the Daredevil suffered several changes and challenges, so drastic that we could see him at a point of time becoming a drifter in upstate New York.
It was not until he reunited with his loyal friend, Franklin P. Nelson (better known as Foggy Nelson), when he regained his attorney license.
Entering the millenium proves to be eventful for the crimson crimefighter, when his publication received a reboot into Volume 2, where he met his wife Milla Donovan (modeled after her creator's wife), assumed leadership to the Ninja group The Hand, fell out with his buddy Foggy, accepted an apprentice in Blindspot, and during one unfortunate event he was even possessed by a demon.
