Takanuva

Takanuva (voiced by Jason Michas) is the only Toa to face Makuta in a Kohlii match and combine with him. He was once a young Matoran called Takua, The Chronicler of Ta-Koro, who then became The Seventh Toa of Mata Nui. He wears The Great Mask of Light, which allows him to turn darkness into Light, and is the one one that defeated Teridax and freed his brother.

Trivia

 * Takanuva will be the only toa to battle when it comes to kohlii against Teridax
