Disk Dueling

Disk Dueling was an illegal sport on Metru Nui that involved two Matoran throwing Kanoka at each other. It was very popular. When a Matoran was angry at another for something, they often chose this sport to settle an argument. The results could be disastrous: not only could Matoran be injured by the force of the throw, they could become victim to the Disk's powers. It's relation, if any, to the Kanoka Disk Toss disk-catching sport is unknown.
