Zaria

Zaria is a Toa of IronToa of IronToa of Iron were the rare Toa drawn from Fe-Matoran stock, commanding metal at a scale that let them tear open Makuta armor and forced the Brotherhood to hunt them across the Matoran Universe., transformed from a Fe-MatoranFe-MatoranIron-aligned Matoran known for exceptional endurance. The only confirmed member, Zaria, became a Toa of Iron., the only named member of that group to be recorded. Like all Fe-Matoran, Zaria wore gunmetal gray and burnt orange armor and possessed innate Iron powers that granted great endurance. As a Toa he wields a staff and controls the element of Iron, able to seize and move metal at will. At some point he killed a member of the Brotherhood of MakutaThe Brotherhood of MakutaAn organization of Makuta created by Mata Nui to police his universe and build Rahi, later seized by Teridax and turned into the instrument of the Plan that overthrew the Great Spirit..

After Mata Nui restored Spherus MagnaSpherus MagnaA desert world of ancient conflict that became the merger point of the Matoran Universe and Bionicle's true endpoint. and deactivated himself, Onua, Tahu, and Gali recruited Zaria for a mission to locate the Great BeingsThe Great BeingsScholar-inventors of Spherus Magna whose creations shaped the Matoran Universe and whose absence defined the conflicts that followed. and ask them to return, honoring Mata Nui's wishes. Onua assigned the GlatorianGlatorianTribal warriors of Spherus Magna who settled disputes through arena combat, until the Skrall conquest enslaved most of them. Gelu to guide the party, which also included the Toa Orde and Chiara. The group set out for the Bota Magna region.

When Onua began explaining the mission, Orde read Chiara's mind and finished her thoughts for her, provoking Chiara to electrify his seat. As the two argued, Zaria used his control of Iron to force both Toa to drop to the ground, telling them to sit down and be quiet so he could hear the rest. Onua judged that including a Toa of Iron in the group had been a good idea.

In Bota Magna the team was captured by a band of intelligent Vorox led by Kabrua, who ordered the prisoners taken to the Vorox city. The captives were then escorted to the edge of the woods and released, with the Vorox intending to hunt them as sport. Zaria devised a plan to ambush the hunters: Orde and Gelu would act as bait while he and Chiara struck from a strategic position with their elemental powers. Zaria hid in preparation for the attack.
