Wairuha

"Welcome, Toa of Water. Do not be afraid-- your body is safe in the ocean's embrace. Only your mind has journeyed here to behold your future. [...] We are what you and the other Toa shall become. When each of you has found all the Great Masks of Power, then shall you be ready to join together and defeat Makuta."

- Toa Kaita Wairuha and Akamai, Comic 3: Triumph of the Toa

Wairuha was the Toa Kaita of Wisdom. He could be formed out of Gali, Kopaka, and Lewa.

Biography
When the Toa Mata were being beaten by Manas in Mangaia, they formed two Toa Kaita. Tahu, Onua, and Pohatu formed Akamai, while Gali, Lewa, and Kopaka formed Wairuha.

Wairuha, along with Akamai, defeated the Manas in Teridax's lair. However, upon approaching Makuta's inner sanctum, Wairuha was then ripped apart back into Lewa, Gali and Kopaka by Makuta's aura of darkness.

After having trouble defeating Kohrak-Kal, Lewa met with Kopaka and Gali, and the three merged into Wairuha Nuva. However, Kohrak-Kal soon teamed up with Gahlok-Kal and Lehvak-Kal, and the Bohrok-Kal merged into the Bohrok-Kal Kaita Ja. Combining its powers, the Bohrok-Kal Kaita overwhelmed Wairuha, and he split into the three Toa Nuva that formed him.

Powers and Equipment
Wairuha wore the Kanohi Rua, The Mask of Wisdom. It gave him the powers of levitation, x-ray vision, and water breathing. When the Toa Mata turned into the Toa Nuva, they could form Wairuha Nuva, who wore the Kanohi Rua Nuva. Wairuha had the powers of Air, Ice, and Water, and these were enhanced as Wairuha Nuva. He carried a dual axe-and-sword, and a shield.

Set Information
Wairuha could be created as a combiner set out of the parts of Gali, Lewa, and Kopaka. Wairuha Nuva could be created out of parts from Kopaka Nuva, Gali Nuva, and Lewa Nuva.
