The Defenders, comicdom's No. 1 non-team, are back - and things are about to get weird in all the best ways! As we begin, the Defenders confront Nebulon and the other-dimensional Squadron Sinister. It's an encounter that will bring Nighthawk into the fold and change the team forever! Magneto and his Ultimate Mutant strike, the Wrecking Crew debuts, Luke Cage and Daredevil join up, and Valkyrie continues the search for answers to her fractured identity! Then, Steve Gerber takes the writing reins, injecting the series with knowing absurdity and cutting social commentary in the form of the bizarre Headmen and the bigoted Sons of the Serpent! Gerber crafted challenging stories that set the tone for the Defenders going forward - and define them even today!
