David Anthony Kraft's run as writer included "The Scorpio Saga" (issues #46, 48–50) and the "Xenogenesis: Day of the Demons" storyline (issues #58–60). The "Defenders for a Day" storyline in issues #62–64 saw dozens of new applicants attempting to join the Defenders, as well as a number of villains attempting to present themselves as Defenders members in order to confuse the authorities and the public as they commit robberies. Kraft later recalled that reactions to the story's off-beat humor were polarized: "readers were either wildly enthusiastic or absolutely and "very" utterly appalled." Kraft and artist Ed Hannigan explained some of the Valykrie's backstory in "The Defenders" #66–68 (December 1978 – February 1979). At Kraft's request, Hannigan helped write issue #67 but found that he could not handle both writing and artwork at once, and so transitioned to being just the series's writer with the following issue.
