This character pilots mecha.

Mechs (plural), or mech (singular) is a broad genre of vehicles (normally walking vehicles) which are usually controlled by a pilot.

Mechs often appear in anime, science fiction, and other genres involving fantastic or futuristic elements. Mechs are generally, though not necessarily, bipedal and are best described ad a mix between a tank and a robot. Some mechs have arms, hands, and fingers capable of grasping objects. A mech that approximates the shape of a human body may allow the use of martial arts movements and swordsmanship, ceremonial acts of honor, saluting, and other human mannerisms.
