Avak

Avak (a.k.a the Trigger) was the Piraka's weapons-crafter.

Dark Hunters
Avak was origially the target of a Dark Hunter mission. A Hunter had been captured and imprisoned, and Avak was the jailer. Avak was deafeted and brought back to the Shadowed One and recruited.

Missions and Activities
4,000 Years Ago: Vezok, Reidak, and Avak free the Kanohi Dragon from its prison in order to pressure Turaga Dume into allowing a Dark Hunter base in Metru Nui. At Dume's refusal, Vezok tries to kill him but Toa Lhikan, Toa Nidhiki, and nine other Toa (one of them most likely Tuyet) intervene. With neither side willing to pick a fight at the moment, the Hunters leave and let the Toa deal with the dragon.

Ignition
Zaktan eventualy decided to go rouge with another 5 of his species: Hakann, Vezok, Reidak, Avak, and Thok.

After Makuta was defeated by Takanuva, rumours began to cuirculate, so Zaktan and the Piraka journeyed to Makuta's lair, to loot it. They found something interseting: the Spear of Fusion. Due to misuse, it split Vezok in two, the other half named Vezon.

While still in Makuta's Lair, Zaktan and the other Piraka suddenly gained knowlege of the Mask of Life. They all wondered how this happened, but only Zaktan knew that Makuta's spirit told them this. Zaktan led the others to the exit,when they were attacked by two Mana-Ko. Vezon escapes,and the other Piraka find the Toa Mata's Toa Canisters,and decided to use them to get to Voya Nui,where the mask was. When they arrived, they acted as Toa to fool all but six Matoran.

After their battles with the Toa Nuva and Toa Inika, Avak and the other Piraka made their way down the staircase leading to the Ignika, fighting their way past guardians and trails along the way. After arriving in the Mask of Life chamber, they encountered Vezon. when the Inika arrived and began to fight Vezon and Fenrakk, the Piraka woke up and stayed out of the way.

Soon after the MoLi flew out of the chamber and into the sea surrounding the island suface. After the Inika went after it Zaktan decided the Piraka should lay low for awhile.

Powers and Weapons
Avak's Elemental power was that of Stone (though he could only activate this power when with another Piraka), and his weapon was a combination Pickaxe and Jackhammer known as a Seismic Pickaxe. In the animated comics this also doubled as a firearm. He could create a prison cell out of thin air that was specifically designed to counter a foe's powers, this took some concentration and the prisons would disappear should Avak be knocked unconscious. He also had X-ray and Telescopic vision

Personality
Avak is a weapon expert and is extremely trigger-happy. However, he is terrible at hand-to-hand combat and rather useless when unarmed. Because of this, he goes to great lengths to protect his weapons from Reidak, who can reduce them to scraps in seconds. He is the only other Piraka besides Zaktan to suspect that something is up regarding the Antidermis.
