Onua (2001)

Onua was the Toa of Earth on the island of Mata Nui.

Toa Mata
After Onua's Canister landed on the shore of Mata Nui and opened, Onua pieced himself together. After walking around, he met Turaga Whenua. It was at that point that Onua learned of his mission: To collect 6 great masks of power and defeat Makuta and awaken the Great Spirit Mata Nui. Then after a short period of time the Toa all officially meet for the first time. But their task was to find six masks each, so the Toa split, and Onua went searching for Kanohi. So with the help and advice from Whenua, Onua found various masks. During this search, Onua noticed that Lewa was in trouble, so he went underground and rescued Lewa from a Muaka by burying it.

Toa Nuva
Shortly after their transformation, the Toa Nuva chose to split up, though they were called back together just as quickly when their Nuva Symbols, the source of their newfound power, were stolen by the Bohrok Kal, who wished to use the Symbols to free the Bahrag. The Toa Nuva searched for the Kanohi Nuva. During this search, Onua went with Turaga Whenua to find a mask. On this search, they first fought a powerful Worm, which Onua defeated by taking advantage of its sensitive hearing. After later avoiding a swarm of Kofo-Jaga, they discovered the mask, guarded by two Manas. Onua used a nearby pocket of magma to attract the heat-loving Kofo-Jaga, distracting the Manas and allowing Onua to get his mask.

Voya Nui
Onua Nuva, along with the other Toa Nuva, arrived on Voya Nui in Toa Canisters, similar to the ones that they came to Mata Nui with. During the battle with the Piraka, Onua stayed conscious the longest, but before he could make it to his comrades, he was struck by the powers of Zaktan, Hakkan and Thok slowing him down and then was struck down by Vezok and slipped into unconscious and was stripped of his mask and his weapons.

Zaktan, the Piraka's leader, ordered the five other Piraka to throw Onua and the other Toa into Mount Valmai, however a volcano eruption postpones the Piraka's plans and the Nuva escaped. Upon their escape from the Piraka, the Nuva met up with the Voya Nui Resistance Team, into which the Matoran decided to battle the Nuva, untrustworthy of anyone calling themselves Toa, as they had already been tricked by the Piraka. In the end, the Matoran and the Nuva aligned themselves together and tried to raid the Piraka's base. However, Brutaka arrived and defeated the Nuva and the Matoran with one blow. Currently, Onua has been placed in Brutaka's custody with the other Toa Nuva. They were then rescued by the Doomtoran. Onua is currently on a new mission with the other Toa Nuva.
