Mighty Avengers #12

Part of Marvel's 2014 Original Sin crossover, this issue of Mighty Avengers splits its striking cover — by Greg Land — right down the middle, pitting two generations of street-level power against each other. On the left, a younger hero with green goggles charges forward wielding a staff while a gun-toting figure looms behind him; on the right, a black-and-gold armored hero crouches menacingly in front of a battle-ready Luke Cage. Al Ewing's series has consistently celebrated Marvel's legacy of heroism, and with Land's clean, kinetic line work framing this tense face-off, issue #12 promises the kind of hard-hitting team drama that makes Mighty Avengers one of 2014's most energetic ensemble books.
