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 Mr. L, 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, Peach's, or Bowser'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 imperiousness and starting the real final battle. Super Dimentio had many attacks, including smashing his hexagonal appendages on the ground, activating a homing blast, and doing a super jump and smashing onto the ground. Super Dimentio was finally defeated in a magnificent explosion, releasing Luigi and the Chaos Heart from control, and leaving Dimentio dying. However, Dimentio leaves one last portion of his power behind to control the Chaos Heart and ensure that all of existence will die with him, and explodes, still smiling.

Powers and abilities
Super Dimentio seems to have physical (as opposed to Dimentio's magical) abilities in the game, which include a giant punch to the ground, jumping, and when its health is low, sliding along the ground from one end of the arena to the other. Other abilities seem to be based on Luigi's, including his signature super jump. The platforms around the arena gain a demonic grin reminiscent of Dimentio and move horizontally, in order to make jumping on Super Dimentio's head more difficult (though this can be used advantageously). Each platform can help Super Dimentio by shooting a flashing square projectile and, when signaled by Super Dimentio, a select few will fire at Mario one after the other (the projectile will be identified by a crosshair that appears where Mario was at the time). Flipping to 3D makes avoiding them easier and also makes the ones fired prior to flipping completely harmless. He also seems to possess an ability similar to the Pal Pill item, in that, should he be provoked by guarding techniques, Super Dimentio will then create several grunts that resemble 8-bit Luigis, that run and jump in the direction the player was when they were summoned, although they are incredibly weak enemies that die if they hit anything, including the walls surrounding the arena.

Trivia
🇵🇲
 * The battle theme of Super Dimentio are the themes of Dimentio, Mr. L, and the Chaos Heart remixed together. According to the InterNed, this theme is called "The Ultimate Show."
 * This is the third Mario RPG where one of the main characters of the Mario series is possessed or brainwashed and used as a puppet to take role of the final boss, not counting Shrowser, as he is still in control of his mind.
 * At the beginning of the fight, Super Dimentio is invincible until the power of the Pure Hearts is used to make him vulnerable again. This was the case with Bowser when he was the final boss of the first Paper Mario, and Shadow Queen's final form when she was the final boss in Paper Mario: The Thousand-Year Door. It was also the case with Count Bleck.
 * This is the only final boss in the Paper Mario series that does not refill his HP.
 * This is the only final boss in the Paper Mario series that doesn't change songs after the intermission.
 * When Super Dimentio extends his neck and the player jumps on his shoulders, they can keep on jumping until he is defeated.
 * For some unknown reason, Super Dimentio slightly resembles Dimentio prior to Dimentio fusing with it, which at first was only a fusion between Luigi and the Chaos Heart.
 * Super Dimentio also bears resemblance to the Brobots, specifically Brobot L-Type, though its attacks are different.
 * Despite being the final boss, the Dark Muth is stronger than Super Dimentio.
 * The official Super Paper Mario player's guide refers Super Dimentio as Dimentio/Mr. L.
