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