Iron

Iron is an Elemental Power.

Species Wielders
Matoran
 * Fe-Matoran represent the Element of Iron. They also contain a very minuscule amount of Elemental Iron energy, just enough that they have incredible strength.
 * Toa of Iron have the Elemental Ability of Iron, allowing the wielder to essentially create, manipulate, and absorb Iron. Their only real limitation is that when they run out of Elemental Iron Energy, they must wait for it to recharge.
 * A Turaga of Iron would hypothetically have small traces of Elemental Iron energy.

Examples

 * Creating any type of metal.
 * Controlling any type of metal.
 * Absorbing any type of metal.
 * Unleashing an Iron Nova Blast.
 * Extreme strength also comes with this Element (Iron grants greater physical strength than the strength offered by stone and earth)

Combinations
It has been confirmed by Greg Farshtey that beings other than Toa couldn't combine powers of any sort to create a Protodermis cage. It has also been confirmed that as long as each of them wields a different Element, any six Toa can create a Protodermis cage.

Users
All of the following beings/objects have or had the Element of Iron:
 * A Toa of Iron from the first Toa team - Deceased
 * Fe-Matoran - Inaccessable
 * An unnamed Toa in the Toa Empire that defended the Coliseum.

Trivia

 * All Toa, Turaga, and Matoran of Iron are male.
 * Most Toa of Iron are were killed by the Makuta because their powers would pose a threat to them.
 * Fe is the chemical symbol for iron on the periodic table
