Exo-Toa

Exo-Toa were special suits of powered armor that Toa could wear, they could also be programmed to act on their own. Each Exo-Toa was equipped with a claw arm and an Electro rocket, and it could enhance the strength of the Toa wearing it by several times. However, it also blocked 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 then salvaged the scrap, intending to study it, but had little time to do so before becoming a Toa Inika. Makuta Chirox took over an Exo-Toa to 'demonstrate' to mutran the new powers beeing made entirely out of antidermis exhibited. Exo-Toa are one of the kinds of things makuta can posses along with other robots, like pit guard robots, and 'empty shells'.
