Juggernaut
Cain Marko
Xavier's stepbrother, empowered not by mutation but by the mystical Crimson Gem of Cyttorak. Once the Juggernaut starts moving, nothing can stop him. Cain spent decades as a villain driven by hatred of his stepbrother, but has occasionally found redemption as a reluctant ally and even X-Man.

Juggernaut has become a beloved character in recent years, with Jed McKay and Ryan Stegman's current X-Men run earning particular praise for its compelling portrayal of Cain Marko as a reformed hero and X-Men member. His redemption arc and tenure on the team has won over many readers who previously saw him as just a one-note bruiser, though his classic unstoppable villain appearances (especially in the '90s animated series) remain iconic. The character's complexity, particularly his fraught relationship with Charles Xavier and his ongoing struggle between his destructive nature and desire for acceptance, generates consistent fan discussion.
