Uncanny X-Men #4

Three striking mutant figures dominate this 2015 Marvel collection's cover — a visor-clad Cyclops flanked by two blonde women in sleek uniforms, their confident stances signaling that the X-Men mean serious business against S.H.I.E.L.D. Chris Bachalo's sharp pencils and inks (finished by Tim Townsend) give the trio a bold, graphic energy that perfectly captures the tension baked into that "vs. S.H.I.E.L.D." subtitle. A pull quote calling it "a glorious celebration of a straight-ahead super-hero story" sets the tone for what looks like a genuinely satisfying mutant-versus-espionage showdown.
