Dimension D

"In this Dimension my attacks are 256 times more powerful!"

- Dimentio

Dimension D(imentio) is a small, green realm created by Dimentio in the game Super Paper Mario. Originally intended to multiply the attack power of Dimentio by 256, the feat was unintentionally granted to all who entered. However, it was claimed by the Heros that everyone who enters Dimension D will gain that amount of power. In actuality, it does nothing at all. Dimension D was really intended to prevent the player from escaping.

Dimentio first challenges the heroes of the game at Dimension D in the Dotwood Tree of The Bitlands. The player also fights a powerful, mind-controlled O'Chunks, called O'Cabbage, a form which was granted added power by Dimentio, here during the last stage in Floro Caverns. When Count Bleck is defeated, Dimentio sends him, a fallen Nastasia (she blocked Dimentio's attack) and Tippi here but all of them escape later.

Trivia

 * The power of everyone's attacks is unaffected by the dimension's powers; this is likely a homage to the data storage abilities of classic consoles. The maximum number for items and other collectibles was usually 255; therefore, 256 would revert back one. Or it could be that everyone's defence was changed as well. 256 could also be referencing the 256-color scheme, which is used in all Paper Mario games as the main colors for all things game-related. It could also be referencing the most common USB stick size in current production, 256 MB.
 * The number 256 features prominently in Super Paper Mario. It is the number of Catch Cards in the game, and in Chapter 5, Flint Cragley's crew members say they have heard his story about the Rainbowzilla 256 times.
 * In the battles with O´Chunks in Chapter 5, Dimension D was used so the player wouldn't be able to escape from the battle.
