- "I asked Vakama about this beast. The Kanohi Dragon had evidently not been seen for generations. According to Vakama, Toa Lhikan and ten of his comrades fought a great battle against the creature and drove it away long, long ago. More than that, he did not know, and Lhikan never cared to share more of the tale. Such silence says a lot about what an awful battle it must have been."

The Kanohi Dragon was a powerful creature that dwelled near Ta-Metru and would fly around Metru Nui, causing the skies to blacken and soot to fall from its body as it snaked through the heavens. Fused to its body were supposed Kanohi Masks. It is believed by some that these scale-like objects are actual Kanohi, meant to lure in unsuspecting victims, while others think that they are nothing more than scales.
Approximately 4,000 years prior to the Great Cataclysm, the Kanohi Dragon was unleashed on Metru Nui. It was freed from its ice cave by Reidak, Vezok, and Avak on orders from the Shadowed One. The goal was for the three Dark Hunters to offer Turaga Dume protection from the beast, in exchange for him allowing for a Dark Hunter base to be created on Metru Nui. Turaga Dume refused, and Lhikan's Team came to fight off the Dragon. After a month of fighting, the dragon was finally defeated, with special help from the 4 Toa of Ice who froze it.
After Botar moved the Tahtorak to Xia, the Tahtorak began fighting it. It destroyed most of Xia during the battle until it was interrupted by the Toa Hagah. The Tahtorak seriously wounded the dragon until Toa Norik used a slowness Rhotuka to slow it down, and Toa Kualus stopped it with some ice blasts. Iruini then moved the Kanohi Dragon's legs away from The Mountain.
It was later released onto Spherus Magna.
