The Ussanui was a vehicle constructed by Takanuva and the Toa Nuva for transport to Makuta's lair. It was built using Rahkshi parts and was powered by Kraata. The vehicle was wrecked when Takanuva used it to break into the lair.
Takanuva rode the Ussanui, a powerful vehicle energized by kraata that could track down Makuta wherever he lurked.
The Ussanui was made from Rahkshi parts, Bohrok parts, and various other materials. No Toa tools were part of its construction.
