The Defenders #39

The Defenders face a crisis on multiple fronts in this September 1976 Marvel issue, with the cover — penciled by Rich Buckler and inked by Dan Adkins — showing Doctor Strange, Luke Cage, and a red-costumed figure in urgent action while a looming, distorted Hulk visage dominates the background. A figure wielding what appears to be mystic energy hovers above, and the cover copy shouts that Clea must not be stopped — and that she's turning the sun into a fireball. With the Hulk seemingly undergoing something alarming and the whole team stretched across a fiery cityscape, this issue captures the wonderfully chaotic energy that made the Defenders one of Marvel's most unpredictable teams of the era.
