The Ultimate Kraangdroid is a gigantic 25 foot tall android body used by Kraang Prime. It is hidden in the walls of the Technodrome. Kraang Prime sits inside its broad chest to seek out and kill all who get in his way. Its head has a fork-like antenna on it that that can shoot a laser beam. It was defeated along with its wearer when the Technodrome plunged into the sea.
- It's head closely resembles the head of Kraang's body from the 1987 Series.
