Iron Man #115

The cover of this 1978 Marvel issue says it all — Iron Man's imposing armored visage looms large while a suited Tony Stark scrambles helplessly below, menaced by the swooping, shadowy Ani-Men bearing down on him before he can don his armor. John Romita Jr.'s cover pencils and Bruce Patterson's inks deliver a real sense of vulnerability and urgency, framing the "Betrayal!" blurb with sharp dramatic tension. With Bill Mantlo scripting and John Romita Jr. on interior art, this issue looks like a compelling test of just how dangerous Tony Stark is without his iron shell.
