Uncanny X-Force #21

Leinil Francis Yu's cover for Uncanny X-Force #21 drops Wolverine — claws bared in his black tactical suit — and a pink-energy-wreathed, sword-wielding figure into the chaos of what looks like a supernatural battlefield, with fallen warriors, scattered blades, and a massive skull strewn across the foreground. A ghostly, robed figure looms in the fiery background, arrows piercing its form against an ominous sky of smoldering orbs. Rick Remender and Greg Tocchini's "Otherworld Chapter Two" promises a team pushed deep into unearthly territory, and this 2012 Marvel issue makes clear the stakes have never felt more mythic.
