Toa Seal

There have been only two known cages, the seal of the Makuta, made by the Toa Metru and the seal of the Bahrag, made by the Toa Mata.

The only known way to free a being from the cage is to take a piece of the Protodermis and feed the same elemental powers that created it onto the piece. This method has been used by Roodaka to free the Makuta of Metru Nui.

Beings other than Toa cannot combine powers of any sort to create a Protodermis cage. In addition, as long as each wields a different element, any six Toa can create a Protodermis cage.
