Earth

"He willed the Earth to rise, to form an impenetrable wall between him and the Rahkshi. He could see the soil beginning to shift, running together and then swirling as if mini cyclones had taken hold."

- Narrator, Mystery of Metru Nui

Earth is an Elemental Power.

Matoran Universe
In the Matoran Universe, Earth is often represented by the Matoran prefix Onu- as well as the color black.

Matoran
 * Onu-Matoran represent the element of Earth and come in shades of black, gray, purple, orange, and tan. Onu-Matoran also contain a very minuscule amount of elemental Earth energy, to the extent that they are able to sense vibrations in the ground and have excellent night vision. They are also physically stronger than other Elemental Types of Matoran. All Matoran, Toa, and Turaga of Earth are male.
 * Toa of Earth possess the Elemental Power of Earth, allowing them to create, control and absorb earth and earth-like substances. Their only real limitation is that when they run out of Elemental Earth Energy, they must wait for it to recharge.
 * Turaga of Earth possess small traces of Elemental Earth power.

Bohrok
 * Nuhvok have a very limited range of Earth powers.
 * The Bahrag have a wider range of Earth powers than the Nuhvok.

Skakdi
 * A Skakdi of Earth would only be able to access their power if they worked with another Skakdi, or if they carried a weapon that would allow them to focus their powers individually.

Examples

 * Creating earth.
 * Manipulating earth and soil.
 * Causing earthquakes.
 * Absorbing earth.
 * Setting a timed Earth blast. (Toa Nuva-exclusive)
 * Unleashing an Earth Nova Blast.

Combinations

 * When combined with the Elemental Power of Fire, it can be used to make lava.
 * When combined with any other five different Elements, or if the powers are manipulated by the Krahka, it creates a Protodermis cage around the target that is only breakable by a second union of the six Elements.
