Tenth Dimension

"All is evil in the 10th dimension... Well, apart from all the evil stuff!"

- Skin description

The Tenth Dimension is the moral opposite of Crash's home dimension. Everything that is considered benevolent in Crash's dimension is malevolent in the Tenth Dimension and vice-versa whereas Crash's dimension is bright and colorful, the Tenth Dimension is dark and gloomy. The Tenth Dimensional equivalent of the luscious N. Sanity Island is the barren Twinsanity Island, where the feral and ferocious Evil Crash resides. The Tenth Dimension had only appeared in Crash Twinsanity, though it is mentioned in the description of Crash's Evil Crash skin in Crash Bandicoot: On the Run!.

History
As a child, Dr. Cortex had accidentally sent his pet parrots Victor and Moritz to the Tenth Dimension while testing his prototype Evolvo-Ray. Victor claimed that the severe "reverso-radiation" in the Tenth Dimension sharpened the skills of the parrots and warped their "fragile, egg-shelled minds", causing them to become the Evil Twins.

Trivia

 * In the cutscene prior to entering the tenth dimension, Cortex breaks the fourth wall and says "It should have been two new dimensions, but we ran out of time.". This is a mocking joke on the game's development, as Traveller's Tales originally planned to include more than one dimension in the game, but this idea was cut due to development deadlines and time issues for the game.
 * The tenth dimension used to look a lot different in an earlier version before the game's release. There used to be an erupting volcano in the background and the sky was filled with clouds.
 * It was meant to be explorable before the game's release.
 * The initial origin behind the character was vastly different, as he was supposed to be Crash Bandicoot himself after undergoing a temporary mutation caused by a malfunctioning Psychetron. His gameplay involved an opposite version of Doc Amok, now named "mock-a-doc" in which he had to trigger hazards to hurt Cortex (who had also been turned into Good Cortex in the process). This was later scrapped to turn them into separate characters, in which only Evil Crash ended up in the Final Game.
