Toa Kaita

Toa Kaita were fusions of three Toa into one single being.

History
The first Toa known to combine into a Toa Kaita are the Toa Mata after they descended from the Kini-Nui into Makuta's Lair. However, merging bodies and minds has been known for a while, as Nuhrii, Vhisola, Orkahm, Tehutti, Ahkmou, and Ehrye demonstrated while the Toa Metru were fighting the King Root on Metru Nui, by forming the Matoran Nui as did Jaller, Onepu, Macku, Matoro, Kongu, and Hewkii to fight a Nui-Jaga before the rebuild.

The first two known Toa Kaita, Akamai and Wairuha, were created from Tahu, Onua, and Pohatu and Lewa, Gali, and Kopaka respectively. These two Toa Kaita defeated the Manas crabs guarding Teridax's Mangaia lair, but were torn back apart into Toa Mata upon entry into the heart of the lair due to being so close to a being of great evil.

When the Toa Mata became Toa Nuva, they were still able to become Toa Kaita. Wairuha Nuva battled the Bohrok-Kal Kaita Ja, but was defeated. Akamai Nuva was never formed, but is assumed to be able to be. So far, the only Kaita that have been formed from two combinations of Toa are Stone, Earth, and Fire; and Water, Air, and Ice. It is possible to form Kaita of different Elements, but none have been seen yet. However they must have different elements (three Toa of Magnetism could not form a Kaita). If the Toa Nuva ever formed Toa Kaita while wearing Adaptive Armor, the Toa Kaita would possess the armor as well.

Trivia

 * It has been confirmed that Toa Hordika cannot merge into Toa Kaita forms. This is because of their mental battle with their inner Rahi.
 * The Toa Metru could have formed Toa Kaita, but they simply did not know how.
 * If only female Toa are merged, the Toa Kaita would most likely be female, though this event has never occurred.
