Kyrehx

Kyrehx was a Mahri Nui Ga-Matoran sentinel assigned to guard Hydruka pens in case of attack.

History
Kyrehx lived a normal life until being sent to Karzahni to be repaired. However, he failed to do so, and Kyrehx was sent to the Southern Continent. During the Great Cataclysm, she was on the land mass that was named Voya Nui. She was one of the inhabitants of the village near the ocean, which sank below into the waters. That city was renamed Mahri Nui.

Years later, Kyrehx saw a glowing object falling from the surface. She swam out to get it, and quickly discovered the plantlife was trying to kill her, the curse the mask gave her. She was saved by Dekar, who managed to pull her back into the city. She then gave the mask to Dekar.

As soon as she left, Kyrehx was captured by Carapar, and brought to Takadox. The latter then used his hypnotic powers on her, tricking her into telling him everything she witnessed.

Before destroying the Stone Cord, the Toa Mahri then led her and all of the Mahri Nui Matoran back to Voya Nui. Axonn then led them to the Nui Caves, where they waited until they sank back into place. She lived on the Mainland for a while before evacuating the Matoran Universe and taking up residence on Spherus Magna. She later moved with the other Ga-Matoran and the Water Tribe to the Great Sea.
