Dr. Robotnik is a comically obese human with a ragged orange mustache, a conical head, a drooping pink nose, conjoined black eyes with red irises and black pupils, he has (almost) no visible ears, a round body and wiry legs. He wears a red, black, and yellow crossed bodysuit with a circular buckle in the center, alongside having gray circles on the sleeves of his top, gray tights and a pair of gray gloves with metal gauntlets and red boots. Very rarely, Robotnik also wears a yellow cape.
