Kaj

Kaj is an Onu-Matoran native to Metru Nui.

Metru Nui
Prior to the Great Cataclysm, Kaj lived and worked in Onu-Metru. He was captured by the Vahki under the command of Makuta Teridax, disguised as Turaga Dume. He was then forced into a Matoran Sphere but was later rescued by the Toa Metru and awakened on the shores of Naho Bay on the Isle of Mata Nui when the Toa Metru sacrificed their Toa Power and became Turaga Metru for the Matoran's sake.

Mata Nui
Kaj's size and strength were diminished and he also lost memories of Metru Nui, both resulting from his confinement in a Matoran Sphere. Shortly after arriving on Mata Nui, under Turaga Metru Whenua's direction, he worked for the construction of Onu-Koro, with reused parts from the Airships that had been used by the Toa to transport the Matoran to Mata Nui. On Mata Nui, Kaj became a Guard of the gate to Onu-Koro. He fled the village with the other Onu-Matoran when the Bohrok attacked. He was later rebuilt after the defeat of the Bohrok-Kal. When the Rahkshi attacked Onu-Koro, he was evacuated from the village along with the other Matoran.

Return to Metru Nui
Kaj later aided in the construction of Boats to return to Metru Nui, where he now resides. After Teridax revealed himself following the awakening of Mata Nui, and Rahkshi swarmed the city of Metru Nui, Kaj's fate is unknown.
