Avengers #13

Thor dominates this Avengers: Fear Itself tie-in cover, Mjolnir raised high as he strides across a chaotic battlefield strewn with fallen figures — including what appears to be a downed Iron Man amid the carnage — while robotic or armored enemies loom in the smoke-filled background. The cover art by Alan Davis and Mark Farmer crackles with urgency, capturing the God of Thunder at the center of a desperate, large-scale conflict. Written by Brian Michael Bendis with interior art by Chris Bachalo, this 2011 issue sits squarely in one of Marvel's most ambitious crossover events of that year.
