Nokama

Nokama was the Toa of Water on Metru Nui.

Toa Metru
Nokama is the Toa Metru of Water and guardian of Ga-Metru. Before becoming a Toa, Nokama was originally a teacher. Although she is now a heroine, she has not lost the habit of trying to instruct others. This is particularly annoying to Matau, who says she should listen more and “speak-teach” less. Nokama takes her responsibilities as a Toa very seriously, and believes they have a duty to the Great Spirit to meet any challenge. She does sometimes miss her old Matoran friends, though, who now do not seem to know how to act toward her. Nokama is wise and extremely resourceful, having once managed to defeat three Rahkshi single-handedly. She is very good at seeing the big picture and making connections between seemingly unrelated events. Along with Onewa, she is the best tactician among the Toa Metru.

Nokama wears the Kanohi Rau, the Great Mask of Translation, which allows her to read ancient Matoran dialects and understand spoken languages, including those spoken by Rahi beasts. Her Toa tools are twin Hydro blades, which can pull her through the Protodermis canals at high speed. They are also strong enough to shatter solid rock, and can channel her power to control water.

Toa Hordika
Of all the Toa Hordika, Nokama is the most comfortable with her new form because of its connection to nature. Her tools are twin Fin Barbs, which can dig through most substances and charge up her Water Rhotuka spinner.

Turaga
As a turaga Nokama was allways telling people what the turaga say they should keep secret(Nokama's carving in the cave;Telling Jaller where the Toa Nuva).
