Nynrah Ghosts

The Nynrah Ghosts were a group of Matoran crafters from the island of Nynrah. Little is known about them, except that they modified the Makuta's armor when the Makuta evolved. They also created the Nynrah Ghostblasters, hence the name..

Other devices they made were the Exo-Toa, Zamor Launchers, and Fohrok. However, they secretly sabotaged the Fohrok, and upon learning of this, the Brotherhood of Makuta hired multiple Dark Hunters to execute the Matoran responsible. One Nynrah Ghost eventually became a Dark Hunter named Phantom.

In the Parallel Universe, the Nynrah Ghosts were wiped out by a team of Toa led by Nidhiki.
