Toa Kaita 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 Layer. However, merging bodies and minds has been known for a while, as Nuhrii, Vhisola, Orkham, Tehutii, Ahkmou, and Erye demonstrated while the Toa Metru were fighting the King Root on Metru Nui, by forming the Matoran Nui.

The first two known Toa Kaita, Akamai and Wairuha, were created from Tahu, Onua, and Pohatu and Lewa, Gali, and Kopaka respectivley. These two Toa Kaita defeted the Manas, but were taken apart into Toa Mata again upon entery into the heart of Makuta's Layer.

When the Toa Mata became Toa Nuva, they were still able to become Toa Kaita. Wairuha battled a Bohrok-Kal Kaita, but was defeated.
