Iron

Iron is an Elemental Power.

Examples

 * Creating iron.
 * Controlling iron.
 * Absorbing iron from the surrounding environment.
 * Unleashing an enormous blast of iron called a "Nova Blast".

Combinations
It has been confirmed by Greg Farshtey that beings other than Toa cannot 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.

Species Wielders
Matoran
 * Matoran of Iron represent the Element of Iron. They also contain a very minuscule amount of Elemental Iron energy.
 * 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.

Users
All of the following beings/objects have or had the Element of Iron:
 * A Toa of Iron from the first Toa team - Deceased
 * All Matoran of Iron - (They have the power, but can't use it.)

Trivia

 * All Toa, Turaga, and Matoran of Iron are male.
