Elementals are creatures who have mastered abilities with particular elements such as wind, earth, fire and water. Their appearance differs depending on which element they have mastered. Blaze is the only known elemental, and he has mastered fire; as such he is portrayed as a being of fire. Tremor has the power of an Earth Elemental, and in his Mortal Kombat X ending, he becomes one.
Cetrion can also be considered an Elemental, holding power over all four elements.
