Toa Seal

A Toa Seal was a cage of Protodermis that could be made by the combination of six different elemental powers from six different Toa.

There have been only two known cages, the seal of Makuta Teridax, 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 Teridax.

Beings other than Toa and Krahka 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.

 * It is believed that Toa Hordika could also make a Toa Seal. However, it would be considerably harder due to to their constant mental struggle.
