Avengers #23

Part of the sweeping "Infinity" crossover, this 2014 installment of Jonathan Hickman's Avengers run brings together a striking assembly of heroes surging forward against a storm-lit void. Leinil Francis Yu's cover captures Captain America, Thor, and a white-hooded blue-skinned figure at the center of the charge, flanked by a crimson-costumed warrior and a long-haired gunslinger below — a full ensemble braced for something enormous. Colorists Sunny Gho and Paul Mounts pour electric tension into every panel, making this one of the run's most visually charged chapter covers.
