Tuyet

Tuyet was a Toa of Water that was part of Lhikans team of Toa. She wore the Mask of Intangibility

From what we know, she lived in an island where the Nui Stone hat been sent to. The Dark Hunters were looking for it, and so she escaped with it to Metru Nui when she aided in the capture of the Kanohi Dragon. And so the Dark Hunters sent Devastator, "Gladiator" and a Keetongu(not the one which lives in Metru Nui) to get her.

Some time later, after 8 Toa and Kodan had already disappeared, a Ta Matoran was found dead holding a tablet that said Toa Tuyet. Lhikan and Nidhiki went to investigate. The next day Kongu made that same discovery, this time in Le Metru. So when Lhikan asked Tuyet if she knew she told him the legend of the Nui Stone and revealed to him that the Dark Hunters thought she had it and the deaths of the Matoran were a 7-day countdown. Another Matoran died the next day, until Lhikan discovered the Nui Stone in Tuyet's home. She managed to take it from him, and when she was about to use it, Nidhiki entered and helped to stop her. Then Lhikan destroyed the Nui Stone.

She was put in a chamber in the Coliseum to decide what to do with her, but she disappeared the next day. Those that were on guard said they had seen a gigantic figure appear from nowhere and disappear again with her. Obvously that must have been Botar, but everybody said that suerly it had been a delusion.

She later died in the Great Cataclysm. Rumours say that she helped Hydraxon in stopping prisioners from escaping from The Pit, others say that she herself tried to escape. At least no one knows how she died.
