Super Dimentio

"GREEEEEEN!"

- Super Dimentio

Super Dimentio is a colossal clown puppet that serves as the final boss of Super Paper Mario. It was created through a fusion of Luigi, Dimentio and the Chaos Heart. Luigi was stated in the Dark Prognosticus as the ideal host for the Chaos Heart's power. After the giant puppet was created, Dimentio added his own power to the combination of Luigi and the Chaos Heart by having the clown eat him, forming Super Dimentio.

Super Dimentio was born shortly after Dimentio assumed control of the Chaos Heart, which he obtained following the defeat of Count Bleck. Super Dimentio harvested the power of the Chaos Heart, rendering him invincible to any of Mario's attacks and thus putting into motion the destruction of all worlds.

Meanwhile in Dimension D, where Dimentio had imprisoned Count Bleck, Tippi and Nastasia, Bleck and his minions expressed feelings of hope and love, restoring the Pure Hearts. The Pure Hearts were then used upon Super Dimentio to weaken the power of the Chaos Heart, nullifying his imperviousness. Super Dimentio was finally defeated in a magnificent explosion, releasing Luigi and the Chaos Heart from control and sending Dimentio to oblivion.

Trivia

 * Super Dimentio is never referred by that name in Nintendo Power's Super Paper Mario guidebook, instead being called Mr. L and Dimentio, Mr. L/Dimentio, and simply "a Mr. L/Dimentio monster."
 * Interestingly, a typically friendly character being fused with a villain to create a climatic boss is remarkably similar to the events of Paper Mario: The Thousand-Year Door ' s final battle, in which the Shadow Queen possesses Princess Peach and fights Mario through Peach's body. However, while Luigi's boss form actually acted as the very final boss of Super Paper Mario, the Shadow Queen was parted with Peach's body before the final battle of Paper Mario: The Thousand-Year Door ended.
 * Super Dimentio's attack pattern is quite similar to that of Mr. L in the Whoa Zone, consisting of jumping and occasionally performing a Super Jump.
 * The battle theme of Super Dimentio are the themes of Dimentio, Mr. L, and the Chaos Heart remixed together.
