Corps Stone

The Corps Stone is a stone filled with energy that allows a Matoran to briefly become a Toa.

Creation
The Vortixx found vials of virus on Xia shortly before the Great Cataclysm. These vials contained Elemental Powers and Toa Power, and were soon ordered to be transferred into stone form to be used as special weaponry. The original intent of the Vortixx was to create a team of Matoran commandos, each equipped with a stone, approximately one-fifth of a bio tall, and one-eighth of a bio wide, to infiltrate and destroy. The plan was going to be to have the commando teams become Toa and utilize their newfound powers and Kanohi to destroy any opposition they encountered during infiltration.

After the Great Cataclysm, the plan was scrapped. A few still saw potential in it, and began selling the many completed Stones to various Makuta. Some of these Makuta saw their potential, and used powers, such as Darkness or Anger to taint the Stones, making them useful in corrupting Matoran into being their minions by rewiring their tainted minds. Giving them the Stones would then create an instant fighting force for the Makuta, making them valuable weapons for Makuta seeking an army that could work as a psychological weapon, as well as a physical weapon. The project was redubbed "Project: Toa Corps".

Powers
The Stones allow the Matoran holding it - as long as the Stone and Matoran element match - to become a Toa for about ten minutes at a time. As a Toa, they have full access of their powers, such as elements and Kanohi. The Stones also contain three forms of power within.
 * Corps Niveau Un - "Level One" - the "initial" form, giving the user all powers of a standard Toa.
 * Corps Niveau Deux - "Level Two" - the "bestial" form, taken after Un fails, much more powerful in all regards, faster, stronger, and more deadly. The instincts of the user start to devolve to an extent, however, and they become more Rahi-like.  The body begins to change in this form, becoming more of a beast to match their instinctual change.
 * Corps Niveau Trois - "Level Three" - the "concept" form, one that should never be taken, for once used, nothing can stop it. Even the creators of the Corps Stones and the Makuta themselves fear this. In concept, the user becomes a massive beast, towering over any structure on the island - approximately half the size of the Coliseum of Metru Nui. This form's powers are relatively unknown, but what is assumed that the mind would be completely shattered, and replaced by that of nothing more than a wild Rahi.
