Dimension X was home of several characters who often create difficulties for the Turtles on Earth, most notably one of the main antagonists the evil alien warlord Krang in the 1987 series. Characters usually use the Trans-Dimensional Portal inside the Technodrome for transportation between Dimension X and the Earth, though other portals and other means of travel are occasionally seen.
Dimension or galaxy controversy
A bit of controversy exists on whether Dimension X really is an alternate dimension, or if it is a distant galaxy. It is not explained where this place is and whether it really is a parallel dimension, as the name suggests, or possibly another galaxy. The cartoon provides arguments for both sides but a definitive determination is never revealed.
Whenever a character refers to it directly, it is called Dimension X. The device used to travel between Earth and Dimension X is called a "dimensional portal", meaning that it allows travel between dimensions. In the cartoon episode Splinter No More , The Shredder tried to use an ancient magic spell to open a portal to Dimension X, Krang warned him that there are other, more terrifying dimensions that he could accidentally access. In the episode Bye Bye Fly , it is explained that travel to Dimension X can also be achieved using a "dimensional warp drive". At many places interplanetary space in Dimension X has a red-orange color. Furthermore, several characters are seen outdoors walking on asteroids without any form of protective gear, something that would kill them in normal space.
There is also sound in space in Dimension X, something that is impossible in normal space. However, also other science fiction makes the mistake of having sound in space, so this argument taken alone is unconvincing.
Although it is never referred to as Galaxy X, some lines of dialogue hint that it is a galaxy called Dimension X. For example, when Shredder takes the crystal from the two children in the episode It Came from Beneath the Sewers , one of the children asks him from where he came. He answers "from Dimension X, in a far off galaxy". Additionally, Krang tries to take energy for the Technodrome in the episode Super Hero for a Day , he says that they need energy from power plants too, because of the distance. There is no distance between alternate dimensions. The Technodrome is located in Dimension X in this episode.
In the episode Bye-Bye Fly. Baxter Stockman tries to use a damaged pan-dimensional warp drive to fly to Dimension-X in an alien spaceship. He fails to reach Dimension-X but ends up in another galaxy where he faces an alien spider.. Krang said he "could fly the Technodrome anywhere, even Dimension X" with the pan-dimensional warp drive.
One possible answer to the controversy is that the name Dimension X means two different things. Since Dimension X is a parallel universe, Krang might come from a spiral galaxy that's both far away from Earth and also located in Dimension X, and this galaxy is also being referred to simply as Dimension X.
In any case, Dimension X is a place in which there are numerous inhabited (or habitable) worlds. In contrast to earthly space, space in Dimension X is colored reddish-orange and various forms of life are guaranteed to be able to survive without any protection or breathing equipment.
- Antrax: He looks like a giant ant wearing the executioner's hood and outfit, and armed with an appropriate axe. In the show he's labeled as "Krang's royal executioner from Dimension X" which makes him an alien rather than another mutant.
- Dregma Brothers
- The Grybyx
- Lord Dregg: Lord Dregg was the villain who replaced Shredder as the Turtles' main enemy in the last two seasons of the 1987 cartoon, voiced by Tony Jay. Along with him came his loyal second-in-command and science officer, Mung (voiced by Cam Clarke), who would always be the subject of Dregg's anger. Lord Dregg was an alien who attempted to take over the world, but his plans were constantly foiled by the Turtles. Eventually, he started a smear campaign against them, which turned the citizens of New York against them and in favor of him; however, this all came to an end in the episode "Doomquest", in which he is unable to fight the titular villain and flees in fear when the Turtles do so, and the populace finally discovered that the Turtles were heroes and Dregg was the villain after April showed them a tape of his true motives. His last attempt involved using a robotic suit to absorb the powers of several other aliens, and kill the Turtles. His plan failed after Donatello and Michelangelo used Krang's android body to shrink him down and banish him to Dimension X.
- Neutrinos: The Neutrinos are the three and a half hipster, flying hotrod driving, teenagers from Dimension X introduced in the 1987 series episode "Hot Rodding Teenagers from Dimension X". They joined the Turtles on multiple adventures up to the 1993 season, after which they did not appear.
- Rock Soldiers
- General Traag: General Traag is the leader of Krang's loyal Rock Soldiers from Dimension X. In the 1987 TV series, Traag (voiced by Peter Renaday) came following the Neutrinos through the dimensional portal. After a small skirmish with the Turtles, the Neutrinos teamed up with them and Michelangelo and Donatello sent both Traag and Granitor back through the portal and to their own dimension.
- Sergeant Granitor: Granitor (voiced by Pat Fraley) is General Tragg's right hand man, and one of Krang's loyal Rock Soldiers from Dimension X.
