Gerry Conway took over as writer with issue #72, and turned the series in a pulp science fiction direction: a lengthy story arc centered on a robot from thousands of years in the future trying to change history. Even long-standing arch-villain the Owl was outfitted with futuristic weaponry and vehicles. Conway also moved Daredevil to San Francisco beginning with Daredevil #86, and simultaneously brought on the Black Widow as a co-star for the series. The Black Widow served as Daredevil’s crime-fighting ally as well as his love interest from issue #81–124 (Nov. 1971–Aug. 1975), of which #93-108 were titled Daredevil and the Black Widow.
In a story arc overlapping Wolfman, Shooter, and McKenzie’s runs on the series, Daredevil reveals his identity to Heather Glenn and becomes partially responsible for the suicide of her father; their relationship would persist but would prove increasingly harmful to both of them. Though the Black Widow returned for a dozen issues (#155–166) and attempted to rekindle her romance with Daredevil, he ultimately rejects her in favor of Glenn.
