Ussalry

The Ussalry was an Onu-Matoran branch of the Mata Nui Military on Mata Nui. It rode Ussal crabs, such as Pewku. These allowed them to move quickly and carry messages between themselves with ease. It is unknown whether it stayed together on Metru Nui or Spherus Magna.

They participated in the Matoran-Rahi War and the The Battle of Kini-Nui I with the Chronicler's Company. The Ussalry was hard-pressed during this war, to the point that it was unable to spare Ta-Koro even a single regiment. The forces of the Ussalry were divided into regiments.

The Ussalry was the third largest force on the island of Mata Nui, behind the Ta-Koro Guard and Gukko Force. Its leader was High Captain Onepu, and two of its members were Damek and Kaj.

Trivia

 * It is possible that only Onu-Matoran members of the Ussalry could wear purple, as all three of its members were the only ones that did. However Akamu did too.
