Dimentio is an enigmatic magician, trickster, and one of the primary antagonists of Super Paper Mario. Exceptionally intelligent and manipulative, he carefully orchestrates events from behind the scenes while maintaining a playful, courteous personality. His true motives are rarely revealed until the final stages of his plans, making him one of the series' most deceptive villains. Dimentio specializes in dimensional magic, allowing him to teleport, duplicate himself, create barriers, manipulate space, summon powerful attacks, and trap opponents in illusions. Despite his cheerful speech and theatrical flair, he possesses a cold and calculating mind, viewing others as disposable tools for achieving ultimate power. His appearance resembles a colorful jester, featuring a split black-and-white mask with a constant smile, a vibrant purple outfit decorated with diamond-shaped patterns, oversized petal-like collars, yellow horns, and a magician's elegance that reflects both comedy and menace.
