Avengers World #21

Tied into the "Before Time Runs Out" / Secret Wars banner, Avengers World #21 delivers a cover that crackles with desperate energy — a sleek, bare-armed hero hurls himself against a massive armored figure with a snarling, goggled face, the two locked in a fierce mid-air collision against a backdrop of fiery cosmic chaos. Jeff Dekal's painted cover art gives the confrontation a cinematic weight, with the sheer size difference between the two combatants making the smaller fighter's defiance all the more gripping. It's a fitting send-off image for a series heading into Marvel's universe-shaking summer event of 2015.
