Metal Sonic was created in the image of Sonic the Hedgehog and is thus mostly built of blue metal. He has a yellow circular depression in his chest with a black center, mirroring the peach skin on Sonic's chest. His head has metal fins resembling Sonic's quills and a pair of triangular "ears." Metal Sonic has a muzzle, shoulder plates, upper arms, legs, and fingers made out of silvery metal. His palms are black, while the backs of his hands are square yellow plates. His forearms and lower legs are blue metal like his head and torso, and he has red feet with white stripes designed to resemble Sonic's shoes. To simulate the hedgehog's eyes, he has a black Visor with cameras behind it, giving it 2 red scleras. Classic Metal Sonic is 76.5 centimeters (2 ft 6.1 in) tall, while Modern Metal Sonic's height is 100 centimeters (3 ft 3 in). Since his creation, he weights 125.2 kilograms (276 lb).
