Toa Maximus

Formation
It is unknown how or exactly when the Toa Maximus was formed - most likely from a preceeding Toa team. All that is known about the team's formation is that all members were chosen from the six main elements: Fire, Water, Air, Earth, Stone, and Ice.

Demise
The Toa Maximus were sent to hunt down Nexus, Emperor of the Makuta Empire, yet Rahkshi and Vahki soldiers prevented this and drained their Toa powers. Leniod was able to save herself and and gave her power (as well as her fellow Toas' powers) up to be stored in the Toa Dome, inside the Great Toa Temple, thus making every Toa Maximus a Turaga.

Toa Neon
A new group of Matoran came to claim the Toa Maximus power in order to become the new Toa team. They were given the power, and set out to defeat Nexus at Tareta's command. The team was not heard from again for several weeks.

Deaths
Nexus' goons, Yosi and Rimnon, came to the Turaga's home in search of the Toa. When they did not find them, all the Turaga were killed, with the exception of Tareta, who was able to hide. Later that day, the new Toa Neon came in search for advice from the Turaga. Tareta took them to the Great Toa Temple, where she sacrificed herself to give Toa power to new members of the Toa Neon and the element of Light for the Toa of Fire and leader of the Toa Neon, Avonan.
