Kotu

Kotu was a Ga-Matoran who was an advisor to Nokama and a Rahi Herder.

Pre-Cataclysm
Before the Great Cataclysm, Kotu inhabited Ga-Metru, a Metru of Metru Nui. Her occupation there was unknown, but one day a Bordakh captured her and brought her to the Coliseum. There, she was put into a Matoran Pod on the order of the Makuta.

Post-Cataclysm
Kotu's pod was captured by the Visorak Horde during their takeover of Metru Nui. After the Battle for Metru Nui, Nokama recovered the pod and took it back to Mata Nui with her. When Kotu awoke, she had no recollection of her past, but had the same determination nevertheless. She quickly rose in status to become one of Nokama's personal aides. She also had the elite job of caring for Rahi that had been freed from Makuta's power.

After the Bohrok Kal Crisis, Nokama announced that there would be a Kohlii Tournament to honor the time of peace (which would turn out to last for not very long). Kotu immediatly assumed she would be picked to team up with Macku, as the two were good friends. But Nokama picked Hahli, something that aroused jealousy in Kotu.

Kotu returned to Metru Nui with the rest of the Matoran, and is now helping rebuild Ga-Metru.
