In the 1987 cartoon series the Trans-Dimensional Portal is a form of teleporter technology that can open dimensional barriers allowing individuals to travel from one dimension to another with relative ease. Usually the portal was used to travel between Dimension X and Earth, but has been used to travel to Dimension Z, the Dimensional Limbo, the 2003 Turtles Dimension, and to Turtle Prime (The Mirage Turtles dimension). Donatello built a small portal that he kept in his lab in the lair. It never worked very well, but occasionally would open long enough for them to get to and from Dimension-X.
