Super Robot

From Wikipedia:

In manga and anime, a Super Robot (スーパーロボット Sūpā Robotto?) 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.
