Protodites were microscopic Rahi which were accidentally freed in the Archives and still infested some sections as of story year 2005. These creatures were being studied by archivists when a Kraawa attempting to escape rocked their container and shattered it. The protodites spread rapidly, kept in check by their sole predator, the Archives mole. It was unknown if protodites ever came to Mata Nui. A unique feature of the protodite was that physical impact caused it to split into two protodites of equal size and strength.
Protodites were one of many creatures in the lower levels of the Archives which the Onu-Matoran could never identify. They were microscopic creatures which escaped their containment cell long before mid-story year 2004 and were on the loose in the Archives ever since.
Protodites were the preferred prey of Archives moles.
