X-Men Unlimited #23

In "Lessons," Professor X confronts the growing cracks in his X-Men team after Magneto’s rise to power over Genosha leaves the mutant cause in disarray. With discipline and skill tested, the professor sets out to reevaluate and reshape his team—before they’re left behind in a world that no longer tolerates weakness. Written by Ben Raab and illustrated by Al Rio, with inks by John Livesay and Jon Holdredge, colors by Kevin Somers, and letters by Comicraft and RS, the issue’s striking cover by Claudio Castellini captures the weight of this pivotal moment.
