Overview
Cain Marko, aka the Juggernaut, is a supervillain and one of the X-Men's most dangerous enemies. Initially appearing as a stepbrother to Charles Xavier, Marko's transformation into Juggernaut came after he encountered the Crimson Gem of Cyttorak. Empowered by this mystical gem, Cain gained immense strength and near-invulnerability, becoming a formidable adversary to the X-Men and other heroes. Despite his immense power, Juggernaut has struggled with his inner demons and often finds himself torn between serving villainous forces and his personal vendettas.
