Exo-Toa

Exo-Toa are special suits of powered armor that Toa can wear, they can also be programmed to act on their own. Each Exo-Toa is equipped with a claw arm and an Electro rocket, and it can enhance the strength of the Toa wearing it by several times. However, it also blocks the Elemental powers of its wearer.

In the time of the Toa Hagah, the Brotherhood of Makuta used Exo-Toa as part of their army, which included Visorak and the Dark Hunters. Thousands of years later, six Exo-Toa were found in the Bohrok's nest by the Toa Mata, the Toa tried to use the armor to defeat the Bohrok Queens, the Bahrag, but found the lack of elemental powers too much of a liability. When the Bohrok-Kal later tried to free the Bahrag, these six Exo-Toa were reduced to scrap metal trying to stop them. Nuparu has since salvaged the scrap intending to study it, but had little time to do so before becoming a Toa Inika.
