Guardians of the Galaxy #12

Part four of six in "The Trial of Jean Grey" brings the cosmic and mutant worlds together in striking fashion. Sara Pichelli's cover captures a fierce Gamora mid-battle, blade raised high above a field of shattered robot enemies, while a determined Jean Grey in her X-Men uniform stands resolute at her side. It's a compelling image of two powerful women fighting back-to-back against impossible odds, and with Brian Michael Bendis writing alongside the artistic talents of Stuart Immonen and Justin Ponsor on interiors, this 2014 Marvel crossover has plenty of firepower behind it.
