Benders: Benders have the ability to manipulate an element.There are five known bending arts; four of them bend a specific physical element, while the fifth bends the energy within the human body itself. The four elemental bending arts are based on the four classical elements; water, earth, fire, and air, and each are manipulated through certain martial art styles which are reminiscent of the qualities of the element itself. Certain benders are able to effectively manipulate their element with very minimum bodily movement, such as only their head. In even rarer cases, it is possible to perform their bending without the aid of physical movement at all, instead using sheer focus and force of will; a skill known as psychic bending. Benders use the Bending Arts.
Chi Blockers: Chi Blockers are non-benders who block their opponents' chi rendering their muscles useless and temporarily disables a Bender's bending. Theu use Chi Blocking.
Swordsmen: Swordsmen use swords and that is all they use. Swordsmen are very fast and skilled in assassination. They can take on multiple benders at a time due their speed.
