Karen Page was a young woman whom was hired as a secretary for Matt Murdock and Foggy Nelson's law firm. From the very start of her career, Karen fell in love with Matt, as did the blind man with her. Page saw Murdock as an incapacitated man who needed help, although he was the very opposite. Matt never had the guts to reveal his feelings for the girl during the first years. Matt and Foggy immediately began competing for her attention which caused tension between the two friends (Foggy once pretended he was the Man Without Fear) until she revealed to them that she was in love with Daredevil. This caused an even weirder vibe, since Matt's secret identity was actually Daredevil. Eventually Karen found out Daredevil's secret identity and she and Matt Murdock fell in love. The relationship however was a rocky one and did not last long. After their relationship had ended, Karen soon moved to Los Angeles to become a soap opera star. In this time she also briefly dated Johnny Blaze (better known as the Ghost Rider) for a short period of time.
Stan Lee and Bill Everett created Karen Page in April 1964.
