Avatar: The Last Airbender
In the animated series "Avatar: The Last Airbender" and its sequel series, there are only four mystical martial arts, which allows certain people called "benders" to freely have control and manipulation of the four elements through real-life martial arts tradition: Waterbending, Earthbending, Firebending and Airbending. These are more based on the elemental structure of the Western and/or the Japanese elements, without a style based around Aether/Void instead having the fifth bending element be spirit. However, there is some overlap of elements as Blood, Lightning, Plants, and Metal are all uniquely special sub-abilities of the other four main elements.
