"Frustrator" is a Dark Hunter, and formerly a Toa of Ice.

History
As a Matoran, Frustrator lived in At-Norx, a far-away land of the Matoran Universe. He was summoned to the Suva by the Toa of Air of the city along with other Matoran to become a new generation of Toa. After being tranformed and winning the respect of the Matoran, the domains of At-Norx became so extense that soon became difficult to govern, so the Turaga assigned each of the Toa as representatives for remote regions. Frustrator became the representative of one of these regions, and began to exploit his Matoran to expand his domains.

The Turaga warned him that his tyrannical treatment towards the Matoran wasn't going to be tolerated, but Frustrator organized an army and tried to overthrow the Turaga. This boldness did not please the other Toa of his team, who conspired against him and stopped his rebellion. Frustrator was overthrown and expelled from his island, with only a few supplies to survive.

Dark Hunter
After being exiled, Frustrator established in a Matoran village and became the hero of the region.

On one occasion, Roodaka and the Dark Hunter Charger attacked his village. Frustrator froze Charger and wounded Roodaka, frustrating the mission of the attackers. During the fight, he began using his Mask of Kindred to copy the features of a Fusa, but Roodaka attacked him with a Mutation Rhotuka at that moment, mutanting him permanently.

The impact of the mutation left him unconscious, and was captured and taken to Odina to face The Shadowed One. He was forced to join the Dark Hunters and was dubbed as Frustrator for frustrating the mission where he was captured.

The Invasion
After Tahkod's death, Frustrator migrated along with everyone from the Matoran Universe to start a new life in Spherus Magna. In his new home, he assumed the role of law enforcer while the former law enforcers, the Toa, apply their powers to other uses.

When the Chorak invaded Spherus Magna, he was grouped with Deriahk, Brutaka and Peduik to rescue Gryk. The four were separated into two groups, with Frustrator and Deriahk going into the forest. There, they managed to locate Gryk and Tarduk Gryk, who then escorted them to the shelter to save them from the Chorak.

Abilities and Traits
Frustrator is always looking to be in the best position of any situation, giving the least possible effort.

As a Toa, he had control over Ice, but after being mutated his Elemental Powers decomposed and can only now express it in an icy breath. Because of the changes he suffered, is can jump much higher and reach greater distances.

Tools
Frustrator wore a Kanohi Faxon, Mask of Kindred, which allowed him to copy the features of a Rahi temporarily. This mask is fused to his face and lost its powers after his mutation.

He is also equipped with an energy cannon on his right arm, which can fire explosive missiles.
