Avengers #6

The Heroic Age continues to deliver with this 2010 entry in Bendis's Avengers run, and John Romita Jr. and Klaus Janson's cover captures the chaos perfectly. A massive green-armored figure with white hair clashes head-on with a long-haired, red-caped Thor, while above them a red-costumed figure grapples with a masked, white-haired opponent — and a winged-helmeted character tumbles through the background. It's a crowd of heavy hitters colliding at full force, exactly the kind of earth-shaking confrontation that defined Marvel's Heroic Age.
