Tahtorak

Tahtorak were a species of sentient Rahi that inhabited the Matoran Universe.

Original Universe
The Tahtorak species was created by the Brotherhood of Makuta as part of their mission to populate the Matoran Universe with Rahi.

Tahtorak were among the Rahi that Vultran kept in Bay 3 of the Ironclad, along with multiple Kanohi Dragons, Kardas Dragons, Más Pequeños, Zahgargak, and the Rahi Nui. In 150,082 CMT, Vultran released all of these Rahi from their enclosures in the Ironclad and deployed them against the attacking ZFT forces in the Battle of Shinobi-Nui. Orion Pax jumped out of one of the ZFT airships and launched repeated blasts of light and ice at a Tahtorak before travelling through a portal and emerging on the roof of the Cabana. The ZFT aircraft then dropped bombs on the Makuta Anima's Rahi, and the rest were scattered by the arrival of Blade Glitchin.

Shattered Mirror Universe
In the Shattered Mirror Universe's Battle of Destral, SM Ynot dragged SM Trantoshen into the path of a rampaging Tahtorak. SM Trantoshen used a Kanohi Komau to force the Tahtorak to attack the Zivon instead, but was crushed in the process and recovered by Spiriah. After the battle was over, SM Ynot ordered SM Sasuken to help out in the cleanup by teleporting the Tahtorak off the island.
