History
Prior of the series, Spinax was created by the member of the Hand of Artakha and later became the servant of the Order of Mata Nui following the Hand's disbandment. He and the other Energy Hounds were used by Hydraxon; the jailer of the Pit to help train the Maxilos robots.

Later when Hydraxon was assigned to become the warden of the Pit, Spinax accompanied him there. Hydraxon then gave Spinax to one of the Maxilos.

The Quest on Mahri Nui
When the Great Cataclysm shattered the Pit, most of the prisoners fled into Mahri Nui as at the same time Hydraxon was killed by Takadox. During the ensuring chaos, Spinax and its Maxilos partner fled into the ocean where they were seperated as Spinax was transformed into a water breather.

Spinax begins his search for his partner and he eventually reunited with the Maxilos who was possessed by Makuta Teridax, though Spinax was unaware of this situation.

Some time later, Teridax and Spinax eventually confronted Dekar-Hydraxon and Teridax engaged him into the battle and attacked him. During the battle, the new Hydraxon regained control of Spinax and ordered him to attacked the Makuta with the command "Manas Zya". However, Teridax escapes and both Hydraxon and Spinax tracked him down.

They eventually tracked him down into the Razor Whale's Tooth where the three-way battle between the Toa Mahri, Barraki and a Gadunka took place. Spinax then saw Teridax and the jailer created the landslide, which caused the three of them carried away. However, Teridax got back up on his feet and used his Kraata power of Rahi Control to regain control of Spinax.
