In manga and anime, a is a gigantic robotic, mechanized, or golem-construct, with an arsenal of fantastic super-powered weapons, extreme resistance to damage unless the plot calls for it, sometimes transformable or combined from two or more robots or vehicles usually piloted by young, daring heroes, and often with mystical or legendary origins. This is distinct from a Real Robot, which is a mecha portrayed as a relatively common and plausible item, used by military organizations in the same manner as tanks or aircraft.
