Air

Air is the substance in which the Matoran breathe. It is usually controlled by a Toa of Air. It can used to create gusts and hurricanes. Some toa of air can even absorb the air in an area and let it go for a powerful attack called a Nova Blast. If the Air power is combined with a Toa of Water's, it can create a thunderstorm. A Toa of Air could also remove the air from an area to suffocate a target.
