Archives Beast

"I hope we're ready for this. The last Archivist that came down here hasn't spoken a word since. Screams a lot, though."

- Toa Metru Whenua, Trial by Fire

The Archives Beast was a bizarre Rahi contained in a locked chamber in the lower levels of the Great Archives. Upon entering its chamber, one would see nothing but an empty room. Then one would quickly discover that the Rahi supposedly inside was in fact the room itself, being able to take on any appearance. Matoran that survived an encounter with this Rahi never came out quite the same. The Onu-Matoran theorized that the Archives Beast's strange ability had some connection to the random reconstitution Kanoka power.

When Toa Whenua and Toa Nuju came into the Archives Beast's cell in search of the Onu-Metru Great Disk, the Rahi had taken on the appearance of an empty room. Toa Nuju dissuaded the Rahi from trapping them by creating a blizzard in the cell, as the beast disliked the cold.
