Piruk

Piruk could sneak in and out of enemy bases to gather information for the Voya Nui Resistance Team very easily. Though this Le-Matoran was not the bravest of Matoran, he was loyal to his friends and more capable than he gave himself credit for. He was the group's best spy. If he was caught, his Shredder Claws could rip through solid metal and make an escape route. Piruk often sharpened them as a nervous habit. The claws were attached to his hands; he could not remove them. Piruk found Zaktan's canister washed up on the beach. The Piraka did nothing to help his poor nerves with his cold voice and strange, shifting body, and Piruk ran away, telling the Piraka he would get someone to help. After all but six of the Matoran had been enslaved, the newly formed resistance team decided on sending Piruk into the Piraka Stronghold where he witnessed Zaktan in conversation with the contents of the Crystal Vat and then Zaktan attacking Avak who disturbed him. Piruk returned to the group's hideout with this disturbing information. The Resistance Team then stole a Zamor Sphere from Vezok. While the group was hiding waiting for Balta to return with the Zamor. After the Toa Nuva fought the Piraka and lost, The Resistance team, without Balta, then did battle with the Toa Nuva whom they did not trust until Balta arrived and stopped the fighting. The 12 heros then joined forces and headed for the Piraka Stronghold. They then burst into the virus chamber where the Brutaka and five Piraka were. Brutaka then brought down all twelve heroes in a single attack, strengthened by the power of the Antidermis.

Piruk was interrogated with the others in the Chamber of Truth. They managed to escape and met up with the new Toa Inika. Together, they split up and headed in three teams to cure the infected Matoran of the Antidermis virus. Piruk went with Velika, Kongu, and Nuparu. They were successful in infiltrating the stronghold, and met up inside. When the Piraka and Brutaka attacked again, this time the Voya Nui Resistance Team separated and began to search for the Toa Nuva. The Matoran found and freed the Toa Nuva. Afterwards, Axonn summoned the entire Matoran population of Voya Nui, leading them into the Nui Caves in preparation for the descent of Voya Nui to the Southern Continent after the Toa Mahri destroyed The Cord. He is currently with the other Matoran of Voya Nui.

Trivia
The infected Matoran the Piraka used seem to look like Piruk, but in brown and black, with a touch of red. Kanohi for these figures seemed to be corrupted color patterns.
