Crystal is a primary Elemental Power.
In the Matoran Universe, Crystal is represented by the Matoran prefix Ki- as well as the colors blue and white.
- Ki-Matoran represent the Element of Crystal. Ki-Matoran also contain a very minuscule amount of Crystal energy. Matoran, Toa, and Turaga of Crystal can be either male or female.
- Toa of Crystal possess the Elemental Power of Crystal, allowing them to create, control, and absorb Crystalline Protodermis. Their only real limitation is that when they run out of Elemental Crystal Energy, they must wait for it to recharge.
- Turaga of Crystal possess small traces of Elemental Crystal power.
- Krånok have a very limited range of Crystal powers.
- Absorbing, launching, and manipulating Crystalline Protodermis.
- Creating crystals.
- Unleashing a Crystal Nova Blast. (Toa-exclusive)
- When combined with the Elemental Powers of Electricity or Lightning, it can be used to create an electrified latticework matrix.
- 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.
