Krang

"What do you think I am, I'm Krang! Indisputable ruler of Dimension X!"

- Krang

Krang (along with Shredder and Lord Dregg), is one of the main antagonists of the 1987 Teenage Mutant Ninja Turtles series. He is an alien warlord from Dimension X who seeks to both conquer Earth and his home Dimension. He is also the partner of Shredder, whom he often argues and fights with.

1987-1996 series
Before the series started, Krang was once a feared, powerful warlord from Dimension X, a universe of continuous war. He controlled an army of Rock Soldiers, under the leadership of his right hand man, General Tragg. One day he was captured and was stripped of his body reducing him to a living brain. Krang (or what was left of him) was then banished from Dimension X, along with his mobile fortress, The Technodrome, to Earth, in hopes he would never return. However, during his stay on Earth, General Tragg continued the war against Dimension X natives, The Neutrinos.

Sometime before the Turtles and Splinter were mutated, Krang met the leader of the Foot Clan, Oroku Saki aka The Shredder, the two began an uneasy alliance. Krang allowed Shredder to access his advance technology in exchange for a new body, in which Krang himself designed. Despite this, Shredder did not live up to this deal as he was afraid that Krang would try to overthrow him. It wasn't until Shredder's countless failed attempts to kill Splinter and the Ninja Turtles that new had to create Krang's new body. When Krang's body was complete, he almost was successful in killing the Turtles and bringing his troops to Earth, but the Turtles foiled his plans and sent Krang, Shredder, and The Technodrome back to Dimension X, and from that point forward, Shredder had no choice but to follow Krang's orders.

Other appearances
Krang was one of the main antagonists in the crossover special Turtles Forever, appearing with much of the cast of the 1987 show, crossing over with the 2003 Ninja Turtle series. He is portrayed as ineffectual and easily defeated, though the 2003 Shredder makes use of his Technodrome to try to destroy the Ninja Turtle multiverse. Krang uses his enlargement powers to try to fight 2003 Shredder and save the multiverse, but is quickly defeated.

Krang would appear again in the 2012 Nickelodeon Teenage Mutant Ninja Turtles series. In the episode "Trans-Dimensional Turtles" he is the secondary antagonist (Shredder does not appear because his voice actor, James Avery, died several years prior.) In the special crossover, the 80s turtles summoned the modern turtles to their dimension to help them stop Krang, who had planted a bomb in the city. After a brief fight in the 80s dimension (in which the 80's turtles don't use their weapons), all the turtles and Krang go to the modern dimension and Krang plants another dimensionizer bomb on the channel 6 building. The turtles and Krang fight again, this time the 80's turtles use their weapons and Krang temporarily grows to giant size. After he is repeatedly kicked in the face by all the turtles (after he fell over), he escapes to the Technodrome in Dimension X, while the turtles discover that the bombs he's been planting were powerful enough to destroy their entire dimension and that they had a short amount of time to shut them all off. Unfortunately, Kraang SubPrime hacks their dimension transporter and sends them to the Technodrome, much to Krang's displeasure. It is then revealed that Krang is actually Sub-Prime's cousin and that he was banished to the 80's dimension because Sub-Prime thought he was an idiot. After helping Sub-Prime fight the turtles, Krang is then beaten and re-banished by Sub-Prime after the turtles state that the dimensionizers were meant to destroy the dimensions that the Kraang were planning on mutating, angering Sub-Prime beyond belief.

He is also an antagonist in the 2016 movie Teenage Mutant Ninja Turtles: Out of the Shadows. (see also: Krang (Out of the Shadows).)

Characteristics
Krang is known for being a brilliant scientist, having designed countless weapons, including his well known android body. He is a cold, cunning, manipulative and somewhat a sadist, as he claims that he enjoys watching "people and animals suffer" In the Archie Comics he is known to be responsible for his massacre on the characters Wingnut and Screwloose home world, and destroying all life on a planet known as Hyrobl.

Despite his frail appearance, many other villains fear Krang, including Shredder, who denies this, Bebop, Rocksteady, and Baxter Stockman (before he crossed mutated into a humanoid fly) Krang is known to have several enemies other then the TMNT and Splinter, this includes Shreeka, a Dimension X criminal who is wanted in thirteen galaxies and was Krang's old partner in crime (and possibly an old girlfriend), Maligna the Malignoid queen, and Lord Dregg, an evil alien warlord and villain of the last two seasons of the series. Despite Shredder's obsession with the Turtles and Splinter, Krang doesn't see them as mortal enemies, but as minor setbacks who need to be destroyed.

Physical appearance
Krang was likely based on The Utroms, who unlike Krang, were a benevolent race of natural brain looking aliens. However, Krang is not an Utrom, in the episode Invasion of the Krangezoids, Krang cloned himself and while they appear to be brain like creatures at first, the cloning process allowed the cloned Krangs to "re-grow" their bodies as "Some lizards can re-grow their tails" it was here when the first (and only) time we get to see Krang's natural form, which were 10 to 12 foot tall hunched back lizard-like humanoids with Krang's "brain" as their head.

However when Krang was stripped from this form, he appears as large pink brain around the size of a basketball with large eyes and a wide mouth with sharp pointed teeth two long slimy tentacles, and a ridged forehead, to move around he designed a tall, powerful, bulky human-like android with many built in weapons including a chip where Krang and his body can grow to giant proportions, Krang himself would rest in the stomach controlling his body. When his body isn't in use, he uses a much smaller bipedal machine known as a "bubble walker" which is equipped with several weapons.

''It is unknown why after Krang was stripped from his natural form, that he never tried to find a way to re-gain it, especially after he found out his clones were able to re-grow their bodies. ''

Whenever Krang speaks, he sometimes croaks like that of a lizard, possibly due to his reptile heritage.

Trivia

 * If Krang is the cousin of Kraang Sub-Prime, it should say that there was no other body which means that he lied on this subject.
