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.

Description
Brutaka wears the Kanohi Olmak - Mask of Dimensional Gates, allowing him to open portals to other places, including pocket dimensions attached to the Bionicle universe (such as the Zone of Darkness) but not alternate realities. He also carries a large, double ended blade, which Axonn gave him. It will give an electric shock and take away the ability to move your hand off of it to anyone who touches it other than Brutaka. He also has two additional blades hidden on his back. His strength is so great that he can wound six Toa Nuva and six Matoran in one blow, and he becomes stronger and meaner when he absorbs the Antidermis virus into his system. His mind is shielded against telepathy and mental attack.

Before Brutaka was an Order member, he once teleported a Tahtorak to Metru Nui just for the fun of it. This Tahtorak ended up playing a big part in the 2005 storyline.

History
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 was carried away by a giant squid.
