Kopaka (Untold Chapters)

Kopaka is a Toa of Ice from Mata Nui. He seems to be level-headed and acts as the deputy of the Toa Mata. In Fire & Ice, he takes Tahu through the cold in order to get to Kini Nui. When they're attacked by a Bohrok, Tahu destroys Kopaka's sword out of anger. Kopaka responds by taking Tahu's sword and freezing it. He then creates a sword out of ice and kills the Bohrok. Kopaka then hits Tahu in the head with his shield after Tahu compliments him on defeating the Bohrok.
