Tahtorak

Tahtorak are massive 40 foot dragon Rahi that can speak Matoran. Their homeland is an island south of Metru Nui that is also home to Keetongu's species.

Only one Tahtorak has been seen so far, in Metru Nui, and it constantly demands "Give me the answer!" without asking his question which is believed to be "How did I get here?" That Tahtorak was last seen disappearing into the Zone of Darkness with Krahka and Zivon. It has since been revealed that it was Brutaka who dropped it into the center of Metru Nui just for fun.

1,000 years later, a wormhole appeared and Krahka and the Tatorahk apppeared on Voya Nui, but their current location on Voya Nui is unknown. However, it is known the Tahtorak will do battle with the Kardas.

The species is also found on Zakaz, where the Skakdi have been known to use them as mounts. The Tahtorak there plan to overthrow the Skakdi, but are waiting for the right moment.
