Dimension D

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

- Dimentio

Dimension D is a small, green dimension created by Dimentio in the game Super Paper Mario. Originally intended to multiply the power of Dimentio by 256, the feat was unintentionally granted to all who entered, meaning that relatively speaking everyone's stats remained the same (Although Dimentio implies after their first encounter that he may have actually hoped for that to happen in regards to Mario and his party). Dimension D was also created as a dimension that could not be escaped, although this did not work out as intended either.

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 twice here. In the second fight he has been brainwashed and is called O'Cabbage. In Dimension D during the last stage of Floro Caverns. When Count Bleck is defeated, Dimentio sends him, an injured Nastasia, and Tippi to this dimension 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.
 * 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.
