Brutaka

Brutaka lived on Voya Nui since long before the Great Cataclysm broke the island off from the Mainland, having been assigned by the Order of Mata Nui to guard the Ignika Mask of Life.

He recently betrayed the Order of Mata Nui after losing faith in Mata Nui because he believed Mata Nui had abandoned him and his kind. He also used to be the friend of another member, Axonn, but after his betrayal, they became fierce enemies.

In exchange for stopping the Toa Nuva, Brutaka was given the Piraka's Zamor Spheres, and he has personally taken the Toa Nuva captive. However, he showed that he still has a decent streak left in him, as he saved some of the Matoran from a deadly Doom Viper out of force of habit, though he seemed to be bothered that this decency still exists.

Hakann and Thok stole Brutaka's power with a special zamor sphere, and Axonn vowed to stay with Brutaka until the Toa Inika and Piraka were able to get back his power. When he awoke, he and Axonn began battling, but Brutaka was defeated.

Botar took him to The Pit, where he met the Barraki. He tried to convince Dekar into giving him the mask of life but Brutaka was carried away by a giant squid.

Mask and Tools
Brutaka wore the Great Mask of Dimentional Gates, which allowed him to open a portal to another location or pocket dimention attached to the BIONICLE universe. He once used this mask to teleport a Tahtorak to Metru Nui just for fun.

He also weilded a Double Bladed Sword that could produce a powerful blast of electricity. This sword was given to him by his x-friend Axonn. He also had two hidden throwing daggers on his back.
