Jaa

Jaa was a Ko-Matoran.

Metru Nui
Jaa was a scholar in Metru Nui and lived in Ko-Metru. He was eventually captured by the Vahki and put into Matoran sphere before being rescued by the Toa Metru and brought to Mata Nui.

Mata Nui
After being awakened on Mata Nui he aided in the construction of Ko-Koro. He was a scribe in Ko-Koro and helped to translate Turaga Nuju's language to the Wall of Prophecy. He was willing to speak to Takua when the latter arrived in The Sanctum and showed him the tunnel that led to The Drifts. He was also rebuilt at the Kini Nui into a stronger form after the attack of the Bohrok-Kal. He later aided in the construction of boats for the return trip to Metru Nui.

Return to Metru Nui
After he returned along with the other Matoran to Metru Nui he helped to rebuild the city until the Staff of Artakha did the rest of the work. He was also present during the ceremony for Matoro.

Spherus Magna
Sometime later he evacuated the Matoran Universe and is currently living on Spherus Magna.
