First Rahi

"Monstrous Rahi, ancient when Metru Nui was young... driven from their home waters... jaws opened wide... tentacles reaching, reaching..."

- Toa Metru Vakama's thoughts, Voyage of Fear

The First Rahi were prehistoric sea beasts of enormous size, created by the Great Beings. Several of these Rahi eventually made it to the shores of Metru Nui, where they were put into the Archives sub-levels to be studied. However, they proved to be too destructive, shattering stasis tubes in other chambers of the Archives, causing many exhibit Rahi to be set free. Alarmed by the catastrophe, Turaga Dume ordered the Rahi to be exiled and gave the Vahki permission to kill any that approached the city. The Onu-Matoran Mavrah, who was part of the study, refused to let his research end, however, and followed the Rahi and chose to live with them in an area near the Great Barrier.

While the Toa Metru were attempting to reach the island of Mata Nui, they fought these creatures, along with Mavrah and some Kralhi the researcher had befriended. Some of the Rahi perished, either by Vahki Vorzakh which had pursued the Toa Metru or by their hungry compatriots. By the battle's end, the remaining Rahi were driven back underwater and their path to the surface was frozen by Nuju.
