Wairuha

Wairuha was a Toa Kaita and the Spirit of Wisdom. He wore the Kanohi Rua. He was made of Lewa, Kopaka, and Gali. Wairuha, along with Akamai, defeated the Manas in Makuta's lair. Wairuha was then ripped apart back into Lewa, Gali and Kopaka because Makuta is the spirit of destuction. When the Toa Mata turned into the Toa Nuva, they could form Wairuha Nuva, who wore the Kanohi Rua Nuva.
