The Defenders first appeared as a feature in "Marvel Feature" #1 (December 1971), where the founding members gather to battle the alien techno-wizard Yandroth and remain as a team afterward. Editor Stan Lee, wanting to write all of the Silver Surfer's stories personally, had asked other writers not to use the character, and suggested that Thomas use Doctor Strange instead. Thomas has also speculated that Lee came up with the team's name: "The 'Defenders' is far too passive a name for my taste. I prefer more aggressive-sounding names like the 'Avengers' or the 'Invaders,' so Stan probably came up with that one." Due to the popularity of their tryout in "Marvel Feature", Marvel soon began publishing "The Defenders" with Steve Englehart writing and Sal Buscema penciling, while Thomas moved into the editor's seat. Despite Lee's continuing edict on the use of the Silver Surfer, he approved Englehart's pitch to include the Silver Surfer in the story.
