Ultimate X-Men #86

Part three of the "Sentinels" arc finds the Ultimate X-Men squaring off against one of Marvel's most imposing mechanical threats, and Yanick Paquette and Serge LaPointe's cover captures the tension beautifully. Center stage, a young X-Men member in a white X-logo uniform delivers a fierce punch directly into a looming Sentinel, energy bursting at the point of impact, while a winged teammate swoops in from above against a rubble-strewn urban backdrop. Robert Kirkman's five-part story is building momentum, and this 2007 chapter looks like a thrilling escalation of the conflict.
