Karen Page (Earth-18200)

Karen Ann Page was best friends with the lawyers Foggy Nelson and Matt Murdock, the latter whom moonlights as the vigilante Daredevil. She was a reporter working for the Daily Bugle trying to uncover evidence tying mayor Wilson Fisk to several crimes. Wilson Fisk (using his considerable influence) had Karen's entire career discredited, but that didn't deter her from continuing her investigation. She was ultimately assassinated by Stanley Carter. Matt (with the assistance of Spider-Man, who's public identity Peter Parker is employed by the Daily Bugle) avenges Karen, defeating Wilson Fisk and Bullseye, using information she had obtained throughout her investigation to put the two men behind bars permanently.
