Water

"A wall of water a thousand feet high crashes into the realm of Karzahni, shattering buildings, leveling everything and everyone in its path."

Water is an Elemental Power.

Spherus Magna/Bara Magna
Element Lords
 * The Element Lord of Water has the ability to create and control Water.

Matoran Universe
In the Matoran Universe, Water is often represented by the Matoran prefix Ga- as well as the color blue. Here, the only naturally occurring water is Liquid Protodermis. Despite this, these beings are able to control the water of Aqua Magna, because the substances are alike in composition and behave similarly in the life processes of Matoran Universe denizens.

Matoran
 * Ga-Matoran represent the Element of Water and come in varying shades of blue. Ga-Matoran also contain a very minuscule amount of Elemental Water Energy, to the extent that they are great swimmers, and can hold their breath longer than other Matoran. All Matoran, Toa, and Turaga of Water are female.
 * Toa of Water possess the Elemental Power of Water, allowing them to create, control and absorb water and similar substances, as well as to channel the healing energy of their own Toa Power or the relinquished Toa Power of other Toa. Their only real limitation is that when they run out of Elemental Water Energy, they must wait for it to recharge.
 * Turaga of Water possess small traces of Elemental Water power, along with very limited healing abilities.

Bohrok
 * Gahlok have a very limited range of Water powers.
 * The Bahrag have a wider range of Water powers than the Gahlok.

Skakdi
 * A Skakdi of Water would only be able to access their power if they worked with another Skakdi, or if they carried a weapon (like Vezok's Water Harpoon) that would allow them to focus their Water power individually.

Examples

 * Creating bursts or focused beams of water/Liquid Protodermis.
 * Forming objects out of water.
 * Manipulation of standing water/Liquid Protodermis or moisture in the atmosphere. (i.e. clouds)
 * Drawing water out of the atmosphere.
 * Absorbing water/Liquid Protodermis.
 * Setting a timed blast of Water. (Toa Nuva-exclusive)
 * Unleashing a Water Nova Blast.

Combinations

 * When combined with the Elemental Power of Air, it can be used to create a storm.
 * When combined with the Elemental Power of Ice, it can be used to create a hailstorm.
 * When combined with the Elemental Power of Fire, it can be used to make steam.
 * When combined with the Elemental Power of Earth, it can be used to make mud.
 * When combined with any other five different Elements by Toa or when 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.
