Exo-Toa

Exo-Toa were special suits of powered armor that were invented by the Nynrah Ghosts. Toa could wear and control them, or they could be programmed to act on their own. Each Exo-Toa was equipped with a claw arm, an Electro rocket, and 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 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 being made entirely out of antidermis exhibited. Exo-Toa are one of the kinds of things Makuta can possess along with other robots, such as Maxilos Robots. Also, when Mata Nui fell into his deep sleep, the ground shook, cracking the armor of a Makuta, but that Makuta was placed inside an Exo-Toa suit to keep him alive.

During the Reign of Shadows, Exo-Toa were used by Teridax to hunt down fugitives and return them to Metru Nui. One such army of Exo-Toa attacked Tahu's team in Karzahni; but were defeated by Onua who then joined the team.

The Exo toa were rarely used as soldiers for Mata Nui, as they have been used as forces for evil.

Set Information

 * The Exo-Toa set would actually allow four Toa Mata sets to fit into it, Tahu, Gali, Lewa and Kopaka. However, because of Pohatu's upside-down torso, he couldn't fit in one due to an error on LEGO's part. (Bionicle fans later discovered a way to modify the set for it to fit Pohatu.) Onua was unable to fit concernining his "head placement" on his set.
