Avengers #19

Part of Jonathan Hickman's sweeping "Infinity" crossover, this 2013 issue pulls readers deep into the chaos with a cover by Leinil Francis Yu that centers on Captain Marvel — her hair blazing with energy, eyes glowing white — set against a brooding crimson sky thick with smoke and shadow. She stands poised and resolute, the bold Avengers logo looming behind her, the whole image radiating both power and an unmistakable sense of stakes. Hickman, Yu, and colorist Sunny Gho make even a single cover feel like the weight of the universe is pressing down on Earth's Mightiest Heroes.
