Krang is later separated from his body and banished to Earth himself along with the Technodrome.

Although menacing at first glance, through the course of the series the Technodrome is almost always powerless and stuck at some remote location ( be it encased in ice, sunken under the ocean, embedded in the Earth's core, or trapped in Dimension X ), making its full capabilities never realized.

Though the Technodrome often manages to acquire enough power to operate, it is always deactivated by the Turtles before any real havoc can ensue.

The Technodrome is capable of surface, subterranean, or underwater travel.

The Technodrome is also equipped with a super portal that can transport the structure through dimensions.

The Technodrome gets trapped in Dimension X for good, and it is pulled into the pit of a ferocious tentacled alien animal whose size rivals the Technodrome itself.

This finally renders it inoperable, and it is not seen again for the remainder of the series until the final episode, in which Donatello and Michaelangelo enter it to retrieve Krang's android body ; by that point, the Technodrome has been irreparably damaged and long abandoned.

This Technodrome is destroyed by the Turtles when they returned in a spaceship equipped with a pulverizer ray, leaving Shredder to retreat back to the original Technodrome.

; Season 1 ( 1987 ): The Technodrome is first encountered under New York City.

In the last episode of the season, Return of the Technodrome, the Technodrome is powered up by diverting power from the power plant at Niagara Falls, and returns to Earth.

; Season 3 ( 1989 ): For most of the season, the Technodrome is nearly powerless near the Earth's core.

The one exception was in the episode Shredderville, where the Turtles dream of a world ruled by Shredder, the Technodrome is above the surface in a very run down New York City.

In the final episode of the season, The Big Blow Out, the Technodrome is in New York City and has opened a giant portal to Dimension X in the sky over it.

; Season 4 ( 1990 ): In the first episode of the season, Plan 6 from Outer Space, it is learned that the Technodrome landed on an asteroid in Dimension X.

; Season 7 ( 1993 ): In the first thirteen episodes of the season ( the " Vacation in Europe " Sideseason, which takes place during season four ) the Technodrome is back in Dimension X, but once the up-to-date episodes begin, the Technodrome is beneath the ocean, where it has remained since the sixth season.

It is implied Krang's Rock Soldiers somehow free the Technodrome and transport it to the planet Balaraphon off-screen prior to the events of the final episode Turtle Trek.

The Technodrome is motionless as it is dragged into the pit of a tentacled monster.

Prior to the start of the 1987 Teenage Mutant Ninja Turtles cartoon, Krang was in command of an army of Rock Soldiers under the leadership of General Traag, and took the completed Technodrome, a powerful mobile battle fortress, and banished Von Drakus who helped Krang build it to Earth.

Much of their quest for world domination hinges on bringing the Technodrome ( Krang's mobile fortress, and his and The Shredder's base of operation ) to the surface as it was either stuck in the earth's core, Dimension X, the arctic, or Arctic Ocean.

Counting from the first meeting between the Turtles and Shredder and Krang, Krang spent seven seasons in the Technodrome, either somewhere on Earth or in Dimension X, scheming to power up his battle fortress and take over the Earth.

" episode of 1987 Teenage Mutant Ninja Turtles show, Shredder and Krang use an abandoned building from the 1964 World's Fair as their hideout when they lose access to the Technodrome, which has ended up stuck in Dimension X.

The Technodrome was designed and built by Krang and his main engineer, Drakus, in Dimension X, Krang's home.

At some point before the series, Krang took the completed Technodrome and banished Drakus to Earth.

Krang utilized this to bring the Technodrome back to Earth, but the Turtles later used this to banish the Technodrome permanently to Dimension X.

; Mini Technodrome: In the two part episode Planet of the Turtleoids, Shredder and Krang build a smaller version of the technodrome.

But Donatello reverses the generator, and when Krang activates it again, the Technodrome burrow itself further underground, and goes all the way down to the core of the Earth.

In the third-to-last episode of the season, The Big Rip-Off, Krang and Shredder manage to steal power cells and recharge the Technodrome.

; Season 6 ( 1992 ): In the first episode of the season, Rock Around the Block, Krang sets up a super-laser to free the Technodrome from its icy prison.

Then, Krang steals some Regenerative Power Cells and uses them to re-power the Technodrome, and move it to New York City.

Donatello re-programs the Technodrome's dimensional portal and sends the Technodrome to Dimension X via remote control, leaving Krang and Shredder stuck on Earth in the process.

; Season 8 ( 1994 ): In the second episode of the season, Wrath of the Rat King, Krang finds out that the Technodrome fell into a black hole in Dimension X.

In that episode, Krang and Shredder finally make their way back to the Technodrome.

After his defeat, Krang and 80's Shredder and Turtles use the still upgraded Technodrome to go back in their own universe.

When Krang was defeated and sent to Morbus, the Technodrome was never seen again in this version.

The transport modules are the vehicles used by Krang, Shredder, Bebop and Rocksteady to move from the Technodrome to New York when the Technodrome is located on the Earth.

The portal allowed Shredder, Krang, Bebop and Rocksteady to travel between Dimension X and Earth during the seasons where the Technodrome is located in Dimension X and allowed Krang to bring his army of Rock Soldiers to Earth when the Technodrome is located on Earth.

The video screen was often used to allow Shredder and Krang to watch the Channel 6 news presented by April O ' Neil even when the Technodrome was located in Dimension X.

In many of the older TMNT video games, the Technodrome is the final level of the game and that the Turtles must fight their way through the various sections of the Technodrome to get to the final boss, alternatively either Shredder or Krang ( or both in succession ) depending on the game.

The closest the Technodrome came to show its full capabilities was in the finale of season three ( Big Blow Out ), and to a lesser extent the season 7 finale " Shredder Triumphant!

In the last episode of the season, The Shredder Is Splintered, Donatello reverses the Technodrome's dimensional portal, and causes the Technodrome to be sucked into Dimension X.

The Turtles manage to trick Shredder into positioning the Technodrome over a sewer, where they had set up a missile they borrowed from the US Army.

The Technodrome remains trapped until the final episode of the season, Shredder Triumphant.

After it arrives in the 2003 cartoon universe following damage sustained to its dimensional portal, the 1987 Shredder uses its technology to find and recover the Utrom Shredder ( Ch ' rell ), Ch ' rell and his foot henchmen subsequently augmenting the Technodrome with Utrom technology, Ch ' rell noting that the Utrom and Dimension X technology work well together despite the ' childish ' nature of Dimension X's technology by comparison.

In the episode A Thing About Rats, the Shredder uses a kind of transport elevator which extends, but remains connected to, the Technodrome.

The portal could be opened at any location on Earth when the Technodrome was in Dimension X and vice versa when the Technodrome was located in Earth, however as Shredder and his gang didn't know the location of the Turtles Lair they were unable to travel there.
