Duos Stone

The Duos Stone is a set of two stones created by the Meiu, allowing Matoran to merge into Toa.

The Stones were created by the Meiu in order to help Matoran be able to protect themselves. The Stones contain Toa Energies and an unknown power. Both halves are one-fifth of a bio tall, and one-tenth of a bio wide.

Two Matoran stand within one bio of each other and hold their Stone facing the other Matoran. Energy flows between the stones and creates an axis of energy between the two Matoran. The axis pulls the two together, merging them into a single Toa.

This Toa is not a Kaita, but a new sort of being. Two Matoran controlling one Toa's body. The unique function of the Duos Stones allows both minds to be in control, and each Matoran's innate Elemental Powers become active within the Toa, for whichever side each Matoran is on.

The bonding process is incredibly painful, and only the strongest can survive it. Anyone of weak constitution or body will be killed by the power. Only some can use it, and only two Matoran have been known to be able to use it.
