Robo appears as a somewhat bulky metallic android, standing at about 5'5" and weighing about a quarter of a ton, built in such a way that he is impervious to gunfire or explosives. Though he may look invincible this way, repeated exposure to explosives seem to knock him out or make him dizzy nonetheless. Alternative weapons such as energy or electromagnetic fields tend to deal the most damage to his system, but as Robo goes through repeated upgrades through the years, he develops some amount of immunity to them. His most prominent feature is his face, which are only two glowing, light-blue eyes, with a line going down on a symmetrical pattern from his forehead to his chin.
