Avengers #15

Tied into the "Fear Itself" crossover, this 2011 installment of Marvel's flagship team book throws three Avengers — Ms. Marvel firing a blazing energy blast, Protector charging forward with glowing fists, and Spider-Woman bracing herself amid the rubble — against a hulking, armor-clad green behemoth crackling with sinister orange runes. Ed McGuinness's cover bristles with kinetic energy, capturing the sheer scale of the threat bearing down on Earth's Mightiest Heroes. With Brian Michael Bendis writing and Chris Bachalo on interior art, this is a must for fans of the era's big, ambitious Marvel storytelling.
