Rahi

The Rahi were the diverse, wide-spread fauna of the Matoran Universe, and biomechanical creatures composed of organic and inorganic Protodermis. The word "Rahi" literally translated to "not us" in the Matoran language, although it was more commonly translated to mean, quite simply, "wildlife". Rahi were generally considered to be possessed of a lower intellectual level than that of the Sapient Species, acting primarily on instinct and out of a desire for basic biological needs such as shelter and sustenance. They are known to have contained very little inner Light; enough to be drained, but not enough to have any notable effect on their judgment.

The majority of the Matoran Universe's Rahi were created by the Brotherhood of Makuta, whose technique involved blending various combinations of viruses in large vats of liquid Protodermis. Later, as the Brotherhood of Makuta became corrupt, they began to design and create more violent Rahi for the organization's own use. A small number of Rahi in the Matoran Universe predated the Makuta, having been created by the Great Beings or other, earlier factions, such as the Hand of Artakha. A few other species of Rahi were the result of Energized Protodermis or other factors acting on preexisting Rahi, sapient beings, or the environment.

Most Rahi migrated to the newly-reformed planet of Spherus Magna after the operating systems of the Matoran Universe were destroyed during the Battle of Bara Magna.
