Dimentio

"Ah ha ha ha ha ha ha ha ha...Ciao!"

- Dimentio

Dimentio is a major antagonist in the game Super Paper Mario. Initially a minion of Count Bleck, Dimentio is a powerful magician capable of several feats, such as teleportation, duplication, and invisibility. Like Mario, he has the power to flip between dimensions, and is control of a dimension of his own, Dimension D.

Dimentio originally followed the orders of Count Bleck to stop Mario and his friends, but soon after Dimentio decided to "help" them along instead. His plan was to have Mario bring down Count Bleck so he could gain control of the Chaos Heart to destroy all worlds and create perfect ones.

Apparently, Dimentio approached Count Bleck on his own at first, offering to serve him. Bleck turned him down, however. It was only after reading about him in the Dark Prognosticus that he allowed Dimentio into his forces.

Dimentio used his Floro Sprout to gain the support of Luigi and use the Chaos Heart to its full potential, transforming himself into Super Dimentio. His plan fell short when Tippi used the Pure Hearts against him and cut off his power from the Chaos Heart, allowing him to be destroyed by Mario.

It is possible that his "aquaintence" he mentions twice in Chapter 5 could have been King Croacus, for Crocus used Floro Sprouts to control the Cragnons, and Dimentio happened to get two of them.

Mysteriously, Tippi seems to have known Dimentio before the events of Super Paper Mario. She recognizes him immediately on their first encounter in the game, during the dialogue shortly before Mario battles Fracktail.

Trivia

 * Dimentio's name comes from the words "dementia", referring to his twisted personality, and "dimension", because he has the power to control various dimensions.
 * Despite his sinister actions, Dimentio has quite a jolly personality.
