Giant-Size X-Men by Jonathan Hickman

A single oversized issue from 2020, Giant-Size X-Men by writer Jonathan Hickman and artist Russell Dauterman is a Marvel one-shot that expands the scope of Hickman's "Dawn of X" era. The story follows Jean Grey and a team of X-Men on a cosmic mission, blending the franchise's mutant soap opera with high-concept sci-fi. It matters as a showcase for Dauterman's lush, detailed art and as a key, standalone moment in Hickman's reimagining of the X-Men's place in the Marvel Universe.
