|Colors||Purple and black|
|Occupation||Onu-Koro Guard, Lightstone Miner|
Kaj was an Onu-Matoran.
Nothing is known about his life when he was on Metru Nui, although he could have served as an Archives guard along with Damek. His Huna was apparently damaged when in Onu-Metru. He was captured by Vahki and put in a Matoran Pod until the Toa Metru rescued him.
On Mata Nui, Kaj served as a lightstone miner in the Cavern of Light. He was evacuated from Onu-Koro during the Gahlok attack. He was rebuilt by the Turaga along with all the other Matoran and guarded Onu-Koro with Damek. He may have fought against the Rahkshi when they attacked Onu-Koro in search for Takua.
Return to Metru Nui
Kaj returned to Metru Nui along with all the other Matoran. He helped rebuild it until the Staff of Artakha was used to repair the rest of the city. He was also present during the ceremony for Matoro.
