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.”

Earth was a primordial Elemental Power involving the formation of landmasses in the Matoran Universe and Spherus Magna. This was one of the most common elements, and was used frequently by Toa, Turaga and Matoran.

Toa of Earth had near-perfect command over the element, while Onu-Matoran were simply stronger than most Matoran, and boasted better night-vision. Turaga of Earth had powers somewhere in the middle.

All users of this element were able to passively see in the dark, and were stronger than other beings.

Examples

• Creating earth.
• Manipulating terrain, soil, and clay.
• Absorbing earth.
• Causing earthquakes.
• Setting a delayed reaction of earth (Toa Nuva-exclusive).
• Unleashing an Earth Nova Blast. (Toa exclusive)

Combinations

With all wielding different elements, six Toa could combine their powers to create a Protodermis cage, capable of sealing away powerful beings, such as the likes of Makuta Teridax, or the Bahrag Queens. Freeing trapped entities required a shard of the prison to be charged with the same elemental powers used to construct it. 

Beings other than Toa could not combine their powers at all, making them the only ones able to do so.

• When mixed with Fire, Earth could create lava.
• When mixed with Water, Earth could create mud
