Dimentio (in Japanese: ディメーン, Dimēn) is the main antagonist of the 2007 video game Super Paper Mario. He is a harlequin magician and starts off as one of Count Bleck's minions and fights Mario and his allies several times during their quest to stop the Chaos Heart and the Void before eventually betraying his boss and revealing himself as the real mastermind, having played both sides in order to usurp control of the Chaos Heart and destroy and remake the multiverse in his own design.
His character theme is "Dimentio, Charming Magician", his battle theme is "It's Showtime", and Super Dimentio's theme is "The Ultimate Show".
Apparently, Dimentio approached Count Bleck on his own at first, offering to serve him. However, Bleck turned him down. It was only after reading about him in the Dark Prognosticus that he allowed Dimentio into his forces. Dimentio is seen with O'Chunks, Mimi, and during several of the meetings with Bleck's henchmen. Even before betraying the Count, he holds disdain for all of Bleck's other followers. He takes every opportunity to mock his fellow minions over their failures and even persuades them to disobey the Count's orders on one occasion.
