Krakua

"Six heroes will one day be called upon to make a perilous journey into the darkest place you can imagine. They will brave the lightning...they will walk through the fire...they will stare into the eyes of evil, and if they waver even once, they will die. And you, Vakama, will have to send them on this quest, knowing they may never return...and knowing that you can do nothing for them but wait and hope."

- Krakua to Toa Metru Vakama, BIONICLE Adventures 10: Time Trap

Krakua was a Toa of Sonics and member of the Order of Mata Nui. Some time in the future, he will be the lone defender of an unknown island fortress.

Matoran
10 years ago, Krakua, a De-Matoran, lived in a secluded village located in the Tren Krom Peninsula. His village despised noise and didn't allow Toa, since Toa were "loud and noisy" and attracted even louder and noisier creatures to fight, creating even more noise. Krakua was different, though, since he apparently liked sound, he usually hummed to himself. Because of his "noisy nature", he never interacted with the other villagers.

Five years ago, Krakua met Mazeka, a servant to the Order of Mata Nui, who tried to help him. After a moment of hurried interaction, Vultraz appeared and attacked his village with a sonic device, felling the other De-Matoran. Jerbraz arrived and saved him while Mazeka was busy battling Vultraz.

After this, Krakua was trained by the Order in fighting and learned how to control the Sonic power he would soon be able to use as a Toa.

Toa
Around the time the Toa Inika were transformed into the Toa Mahri, the Order of Mata Nui, badly needing new allies, arranged for Krakua, who was still a Matoran, to become a Toa. He then served the Order and, at some point, met Lesovikk, who was hunting down the tyrant Karzahni. He gave Lesovikk information about the Pit and told him that if Karzahni was defeated, someone would come to take him away.

Lately, he was sent to Voya Nui to summon Axonn by Toa Helryx. Axonn attacked Krakua on sight but, after he subdued him, Axonn realized that Krakua was an Order of Mata Nui servant.

At some point, he traveled with Helryx to Metru Nui to inform Takanuva of the Energy Storm that would occur in Karda Nui. In the battle between the Order and the Brotherhood in Metru Nui, Krakua became a full member to aid in the war between the Order of Mata Nui and the Brotherhood of Makuta. He used his sonic powers to create a pitch that would awaken the Bohrok, which distracted the Rahkshi long enough for the Toa and Order to destroy the ones that had broken through the defenses. After Teridax's death, he evacuated Metru Nui and is currently living on Spherus Magna.

At some point in the future, he will defend an unknown fortress. Krakua will then be able to communicate across time with Toa Metru Vakama, who was having a vision of the future. Krakua will tell Vakama that if he failed his mission, Krakua would never exist and that, to succeed, Vakama would have to be willing to destroy the future to stop evil from spreading. He also will tell him that Vakama would one day have to send a group of heroes into danger and not be able to do anything about it. It is known he will be referring to Vakama indirectly, causing Jaller, Kongu, Hahli, Matoro, Hewkii, and Nuparu to become the Toa Inika.

Dark Mirror
In the Parallel Universe, Krakua was a member of Pohatu and Lesovikk's rebel group. During a fierce battle at the Coliseum, Krakua and Ahkmou killed the corrupt Toa Gali.

Powers and Equipment
Krakua controlled Sonics, and had sound-related powers, such as creating shockwaves of sound powerful enough to shatter stone and metallic protodermis. He carried a sonic sword that he used to channel his power.

Krakua also wore a Kanohi Suletu, the Great Mask of Telepathy, which enabled him to stay one step ahead of his enemies by listening to their thoughts.
