He was once one of the two rulers of Hapori-Nui, but he went mad and was imprisoned in battle against his late brother Hapori Tohu, although Tohu was reverted into a Matoran in the process. The Vahki were made in his image.
He assisted Hapori Dume in his battle against Hapori Tohu. Not much is known about him, except his first appearance is in Part 3 of The Third Movie and looks like a giant Pakari/Pakari Nuva-faced Piraka with green armor and claws, a black interior, and a double-bladed sword with one end similar to Superkid11's pizza sword and an Inika weapon merged and the other similar to Lhikan's Skyboard. He flew on the mothership with his zorak minions and destroyed some ships and bz guards with an unknown device.
