Ninja
In Japanese history, a Ninja (忍者, ninja) was one who was specially trained in a variety of unorthodox arts of war. The methods used by ninja included assassination, espionage, and a variety of martial arts. They are akin to the spies of today.
It is said that a ninja had amazing physical abilities, which they acquired through daily training and dedication to their art. Some of these abilities include a fast stride and a high jump. The ninja also used the elements in their 'arts of concealment and espionage'. The mastering of these elemental arts allowed them to create illusions or distractions, allowing them to disappear freely.
