The First Rahi are a collection of enormous marine Rahi.


The First Rahi were created over 100,000 years ago by the Great Beings to inhabit the Matoran Universe.[2][3]

Several of these Rahi eventually made it to the shores of Metru Nui, where they were kept in the Archives sub-levels to be studied. Due to the damage they caused to the Archives, Turaga Dume exiled the Rahi and gave the Vahki permission to kill any that approached the city. Mavrah refused to let his research end, and left Metru Nui with the Rahi, who took shelter in watery tunnels within the Great Barrier, where they periodically ate one another.[4]

While the Toa Metru were attempting to reach the island of Mata Nui aboard The Lhikan, they passed through the tunnels, where the Rahi attacked them. The Toa fought back until they were captured by Mavrah's Kralhi. While the Toa Metru were trying to escape, several Vahki Vorzakh, which had pursued the Toa Metru, attacked them, agitating the Rahi and causing a frenzy in the tunnels. Several of the Rahi perished, either by the Vorzakh 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.[4]

After the Great Spirit Robot was critically damaged in the Battle of Bara Magna, the remaining first Rahi were evacuated to Spherus Magna.[1]
