Brutaka

Brutaka has 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 has recently betrayed the Order after losing faith in Mata Nui when his species ended up living miserably. He also used to be another member, Axonn's friend, but after his betrayal, they have become fierce enemies.

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 but not alternate realities. He also carries a large, double ended blade, which Axonn gave him. It also has electrical powers, which he used on Axonn. He also has two additional blades hidden on his back. His strength is so great that he can wound six Toa 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.

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 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 seems to be bothered that this decency still exists.

While the Inika were below ground, Brutaka battled his former-friend, Axxon, who defeated Brutaka and Botar took him to the Pit, where he presumably meets the Barraki.
