Hulk #20

Part of the "Fall of the Hulks" saga, this 2010 Marvel issue brings Jeph Loeb and cover artists Ed McGuinness and Mark Farmer together for a genuinely electric image: the massive Red Hulk clashes head-on with a blue-furred Beast, laser beams cutting across the frame while a glowing, water-formed figure crackles with energy below and a winged figure and Storm look on from the edges. The sheer density of heavy-hitters packed onto this cover gives "Man Nor Beast" the feel of a story that isn't pulling any punches.
