Toa of Stone was a title given to a Toa who wielded the Element of Stone. Toa of Stone were almost always transformed from a Matoran of Stone, although Pohatu was an exception. Should a Toa of Stone fulfill his destiny, they were given the option of sacrificing their Toa Power and becoming a Turaga of Stone. If a Toa of Stone lost their Kanohi, their Elemental powers would be halved and their overall strength greatly weakened.
