Acid

"Kopaka spun around just in time to avoid a noxious stream of yellowish-green liquid. The stream hit a cluster of boulders instead, and within seconds the solid rocks had melted away into nothing but a bit of greenish steam."

- Narrator, Beware the Bohrok

Acid is a Power, of the tertiary Elemental Power Disintegration, that allows the wielder to create acidic substances.

Murtua
On the planet Murtua, Acid a tertiary Elemental Power of its' own and is often represented by the Matoran prefix Cai- and the colors black and green.

Matoran

 * Cai-Matoran represent the Element of Acid and come in color combinations of black and green. Cai-Matoran also contain a very minuscule amount of Acid energy. Acid allows for equal numbers of both male and female Matoran, Toa, and Turaga.
 * Toa of Acid possess the Elemental Power of Acid, allowing them to control, create, and absorb acidic substances. Their only real limitation is that when they run out of Elemental Acid Energy, they must wait for it to recharge.
 * Turaga of Acid possess small traces of Elemental Acid power.

Bohrok

 * Lehvak have a very limited range of Acid powers.
 * The Bahrag have a wider range of Acid powers than the Lehvak.

Visorak

 * Keelerak have a very limited range of Acid powers.

Examples

 * Absorbing, manipulating, and launching acidic-based attacks.
 * Unleashing a Acid Nova Blast. (Toa-exclusive)

Combinations

 * Beings other than Toa and the Krahka cannot combine powers of any sort to create a Protodermis Cage. As long as each wields a different element, and providing that Light and Shadow are not included at the same time, then any six Toa can create a Protodermis Cage.
