Kolhii

Koli, later known as Kolhii was a popular Matoran sport originally played by Po-Matoran and later played by all Matoran on Mata Nui. Originally made by Turaga Whenua and Onewa to settle arguments between Onu-Matoran and Po-Matoran, Koli was reinvented (and renamed 'Kolhii') later when Hewkii saved Macku from an airborne rock during the Bohrok invasion of Ga-Koro.

Players and icons
Hewkii was the reigning champion and best Koli player on Mata Nui. He won many Copper Masks. The icon of Koli was Pohatu, the Toa Mata of Stone. Hahli and Macku eventually won the tournament.

History
Koli was first invented by Turaga Whenua and Onewa to settle disputes between their villagers. It was mainly played by Po-Matoran. During the Battle of Ga-Koro, Hewkii saved Macku from a flying rock, which became the idea behind the reinvention of the sport. The new version was named 'Kolhii' and all Matoran played it. Each village had their own Kolhii team, consisting of two Matoran.

When Takanuva challenged the Makuta in his lair, Makuta challenged Takanuva to a game of Kolhii with balls of light and shadow energy. In the end, Takanuva and Makuta fell into a pool of Energized Protodermis and fused into Takutanuva.

Trivia
The Mask of Light was revealed to the population of Mata Nui during the post-ceremony of a Kolhii game celebrating the new Ta-Koro Kolhii Stadium.
