Brutaka was a member of the Order of Mata Nui.
Brutaka was once a loyal guardian of the Matoran and Axonn's best friend. Convinced that Mata Nui had abandoned his people, Brutaka turned selfish and corrupt. Powerful and enough to defeat six Toa with one blow of his double-bladed weapon, Brutaka alone was as great a threat as all of the Piraka combined. He wore the Kanohi Olmak, the Mask of Dimensional Gates.
After Brutaka was mutated by the waters of the Pit, twisted spikes jutted out of his armor, and what looked like a long dorsal fin ran down his back. He could fire blasts of raw power from his hands and from his sword.
He was a seasoned warrior, having a longer history of battle than even Makuta. He could break through stasis fields with his sword.
Whereas Axonn was a warrior, Brutaka was more of a scholar, versed in the art of the sword. His intelligence and ability to analyze facts quickly were seen as a good combination with Axonn's raw power.
Brutaka began his life as a lieutenant in the army of Makuta but rapidly grew dissatisfied with the regimented existence he led. He was recruited by the Order of Mata Nui and turned into a roving troubleshooter, achieving many great things but also causing his share of trouble. For instance, he once used his mask power to transport a Tahtorak from its home island to Metru Nui.
Brutaka and Axonn defeated a number of enemies who tried to claim the Kanohi Ignika.
Brutaka turned against the Order and was banished to the Pit.
Brutaka carried a twin-bladed sword and wore the Kanohi Olmak. Exposure to antidermis had the strange effect of strengthening him rather than enslaving his mind. The extent of his powers is unknown, but he had enormous strength, had the ability to shoot energy from his sword, and was formidable enough to have defeated Axonn on one occasion.
In the alternate universe of the Toa Empire, Krika had heard Matoran legends of a Brutaka. It was said that he was a great hero who guarded a valuable treasure.
After being the Pit, Brutaka was tall, lean, and strong. He wore a domed helmet and carried a wicked double-bladed sword.
Brutaka could hurl bolts of energy from his sword.
After falling into the pool where the Makuta species was created, Brutaka floated three feet off the floor. Green fire crackled from his eyes and the tips of his fingers. His armor had cracked in numerous places as the tissue it covered expanded. An aura of pure power surrounded him that was so bright that Axonn had to cover his eyes. It was Brutaka's body and Brutaka's voice, but the words he spoke came from the "essence of the Makuta species." Brutaka had a grip of iron, and his touch burned. The changed Brutaka had a voice like thunder.
Makuta antidermis had an effect on Brutaka. Absorbing it somehow made him stronger.
Brutaka's mask was shattered by a bolt of energy from Makuta Teridax. Even without his mask, Brutaka seemed frighteningly powerful. He glowed green and floated several inches off the floor. He claimed to know all that Teridax had forgotten.
Brutaka's mind was well-shielded against mental attack.
Brutaka and Axonn were members of the Order of Mata Nui and long-time friends. Both Brutaka and Axonn had enormous power. Brutaka wore the Kanohi Olmak, the Mask of Dimensional Gates, and carried a twin-bladed sword.
Brutaka's powered-up state after being immersed in the Makuta pool was going to last for a while. He was closer to the power level of a Makuta than that of Tren Krom. Brutaka's changes were long-lasting but not permanent.
Brutaka got his Olmak from the Order of Mata Nui.
After falling into the Makuta pool, Brutaka possessed the powers of a Makuta.
