Dimension X was home of several characters who often create difficulties for the Ninja Turtles, most notably one of their main antagonists, Krang, but also some of their allies and friends, like the Neutrinos.
A bit of controversy exists on whether Dimension X is a dimension, or a galaxy in the same universe as the Milky Way. The cartoon provides arguments for both sides but a definitive determination is never revealed.
For example, interplanetary space in Dimension X is often depicted as orange or reddish. However, Shredder when taking the crystal from the children in It Came from Beneath the Sewers, he tells them he came "from Dimension X, in a far off galaxy". In some episodes, like Super Hero for a Day, Krang mentions the distance between Earth and Dimension X.
