—Knight's first line, The Invasion Part One

Knight, aka Kraang SubPrime, is an enemy of the Ninja Turtles. As an Utrom who is the brother of Bishop and cousin of Krang, he was once one of the main members of the Utrom High Council alongside his brother, Queen, Rook, and Pawn. But until an Utrom scientist, Kraang, mutated himself and gained psychic powers, him and a great amount of Utroms were corrupted by the mutant Utrom. Now as the second-in-command of the Kraang Hive Mind, he serves for Kraang Prime to mutate and conquer planets with the Mutagen as their main weapon. Recently, as the Kraang Hive Mind was interested in mutating the Earth, he disguised himself as a teenage, human girl known as Irma Langinstein. He "befriended" April O'Neil, a girl that The Kraang need to perfect their Mutagen, in order to eventually discover the Turtle's Lair to initiate the Kraang Invasion. Once, when the Triceraton Empire arrived to Earth to annihilate The Kraang, him and Kraang were both destroyed inside of the Technodrome by the Triceraton Destroyer's devastator. He wields the Spy Kraangdroid, Mutagen, and a mechanical claw as his signature weapons of choice. He has a rivalry with Bishop, April O'Neil, and Triceraton Empire. Knight debuts in The Invasion Part One.


Nexons ago, Knight was a main member of the Utrom High Council alongside with Bishop (his brother), Queen, Pawn, and Rook in Dimension X. After some time, when the Utrom scientist, Kraang, mutated himself with the Mutagen and became a gigantic, psychic mutant Utrom, he corrupted Knight and a great majority of the Utroms. Knight, now renamed as Kraang SubPrime, became the second-in-command of the Kraang Hive Mind. From there on, he started to invade and mutate other planets with the Mutagen. He eventually became known as a traitor towards the Utrom High Council.
