Book excerpt: Hulk, Dr. Strange, Sub-Mariner, Valkyrie and Nighthawk join up with Luke Cage, Daredevil and Son of Satan to take on the likes of the Wrecking Crew, Satannish and Asmodeus. Then, spinning out of a storyline in Marvel Two-In-One, comes Steve Gerber! Deconstructing genre conventions and adding a healthy dose of absurdity, Gerber's innovative run turned the expectations of readers on their heads, so suitably we're including the original Atlas Era appearances of the Headmen-Gorilla Man, Jerold Morgan and Chondu the Mystic! COLLECTING: DEFENDERS 17-21, GIANT-SIZE DEFENDERS 2-4, MARVEL TWO-IN-ONE 6-7
