The Fixer was a boxing organizer who often fixed fights by using blackmail and extortion. Daredevil's father Battlin' Jack Murdock was signed by Fixer - without Murdock's knowledge, Fixer fixed fights to build up Murdock's reputation as a comeback fighter. Eventually, the Fixer ordered Murdock to throw a fight against Rocky Davis. Murdock refused and after winning the fight, Fixer had him murdered. When Daredevil went to seek justice for his father's murder, the Fixer died of a heart attack while running from the costumed hero.
