Krang (1987 TV series)

Krang is a character loosely based on the Utrom race from the original comic, and is an ally of Shredder. In Dimension X he was a powerful dictator/warlord who led brutal campaigns of Rock Soldiers, with fanatically loyal-to-Krang General Traag as his direct subordinate. He also took the completed Technodrome, a powerful mobile battle fortress, and banished Drakus who helped Krang build it to Earth.

One day, an unexplained, bizarre incident occurred that caused Krang to be stripped of his body and reduced to a brain-like form, also resulting in his exile from Dimension X to Earth. After he was banished from his original dimension, along with his operative fortress the Technodrome, they somehow found their way into the hands of Oroku Saki. Krang allied himself with the Shredder, who, along with his robotic Foot Soldier army, moved into the Technodrome.

Krang pleaded for a new body in exchange for his developed technology and help in conquering the world. Shredder resisted, fearing that his ally could come to rival him; however he finally submitted once he lost hope for defeating the TMNT himself and needed Krang's help, he finally constructed the android body from Krang's own blueprints named Bangerang in the season 1 episode Shredder & Splintered. Krang returned to his megalomaniac personality as he dreamed to bring an army of Rock soldiers to Earth and rule it alongside (or maybe without) The Shredder. Indeed, in the season 3 episode Shredderville the Turtles have a dream of a parallel world in which they never lived, and Shredder had no problem taking over the world. In this world, Shredder abandoned Krang after his conquest was complete, leaving him with no body and a heavily-damaged Technodrome.

Krang rarely joined in actual combat with the turtles. Usually the only times he was directly involved with a fight was when the Technodrome was fully up and running. For seven years he organized the plots of the Foot Clan to conquer earth, it probably only became his objective after he was exiled on the Earth, but this point is never made clear, most involved the short-term objective of re-powering the Technodrome. He does not share Shredder's obsession with the Turtles and Splinter; while Shredder sees them as mortal enemies, Krang seems to regard them more like annoyances to be destroyed when they interfere in his plans.

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.

Eventually the Turtles managed to banish the Technodrome back to Dimension X without Krang and Shredder. At that point they began operating out of an old science building. Due to damage to Krang's android body, he was forced to use his bubble walker while on earth. Krang and Shredder eventually returned to the Technodrome, only to see it into its final battle in the season 8 episode Turtle Trek, where the Turtles destroy the engines of the Technodrome, trapping it and its inhabitants in Dimension X and putting an end to Krang's plans. Krang's Android body was left in the remains of the Technodrome when it was abandoned. Krang was only seen once again, when he and Shredder were briefly transported to earth by Lord Dregg.

Krang spent the next two years in Dimension X, until he was contacted by Lord Dregg. Dregg arranged for him and Shredder to come back to Earth, to help him fight the Turtles. However, Dregg betrays them, and drains Krang's intelligence. Shredder escapes and restores Krang, but Dregg captures them again. Finally, the Turtles spoil his plan and transport Shredder and Krang back to Dimension X.

In the series finale, Divide and Conquer, the Turtles return to the Technodrome to take Krang's android body, which they need to fight Dregg. Krang is nowhere to be seen, but it is assumed that he is still somewhere in Dimension X.

Turtles Forever
Krang is a major character in the special Turtles Forever in which he, Shredder and the turtles from the 1987 show end up in the 2003 universe. Although Shredder was able to find his 2003 counterpart, he was unable to find Krang's, even though he exists in this universe (albeit as a regular, non-evil Utrom). He appears alongside Shredder and is present when he resurrects the Utrom Shredder. At first Krang thinks Ch'rell Shredder isn't that bad, since he physically resembles Krang himself. However, Krang quickly becomes annoyed after Ch'rell takes over the Technodrome and won't allow anyone else to use the Trans-Dimensional portal. Karai quickly pulls Krang from his android body and orders him to not bother Ch'rell Shredder again.

When Ch'rell completely turns on Krang and the "1988 Shredder", they both join forces with the Turtles once Karai frees them and Splinter. Ch'rell, using the same technology Krang designed for his android body, grows to an immense size. So Krang does the same with his android body, and attempts to fight Ch'rell, but is quickly defeated. This is only the third time Krang takes his android body into battle.

At the end of the story, after Ch'rell is defeated, Shredder and Krang say they are going to use a new Giggle ray Krang invented on the Turtles once they return to their own universe.
