What If...? #13

In What If...? #13, writer Kurt Busiek and artist Vince Mielcarek explore a chilling alternate reality where Professor X—rather than Cain Marko—becomes the Juggernaut after touching the ruby of Cyttorak. Trapped under rubble in Korea for years, Xavier survives, observing the world’s cruelty toward mutants, until he emerges to seize control with a force of mutant X-Men. When Cyclops and a defiant few break away, teaming with Magneto and the original Juggernaut, they plot to stop the man who was once their mentor—now a tyrant beyond reason. Jim Lee’s striking cover captures the moment of transformation, while the story unfolds with tense, morally complex stakes.
