Loki: Agent of Asgard #10

Al Ewing and Lee Garbett's Loki: Agent of Asgard #10 delivers one of the most arresting covers of 2015 — a massive, blue-skinned Loki in his horned crown, mouth thrown open in a scream, with a smaller green-skinned Loki caught inside that open maw, screaming in turn. It's a surreal, vertigo-inducing image that captures the trickster god's fractured identity with genuine unease. Nolan Woodard's cool blues and purples give the whole thing an eerie, otherworldly atmosphere that makes "Not Forgiven" feel like a chapter you won't want to skip.
