Kraang Prime is with him, supervising Subprime's repair of the Techndrome. Subprime finally gets the Technodrome operational and pilots it out of the water. Subprime personally defends an assault led by Bishop, the turtles and Leatherhead, which is when Bishop reveals that Subprime (or "Subsubprime") was originally a fellow Utrom. The Technodrome's show of power is short-lived, as the Triceraton fleet begins their invasion, and the Technodrome is their first target.

It was there that it was revealed that he and Krang are cousins, and apologized for banishing him to the 2D earth of the 1987 ninja turtles. After the collective turtles make short work of their Kraangdroids, he and Krang follow them to the 2D earth to try and stop them. They then teleport back to the Technrodrome, where once again the turtles fight and defeat Sub-Prime's forces. Shortly after, the turtles reveal the that the dimensionizer would've destroyed the realities that the Kraang have been trying to mutate for thousands of years, something Sub-Prime had no idea of.
