Dr. Robotnik

Dr. Robotnik is a rotund mad scientist who plans to conquer the world to build his own Eggman Empire. While he has gone through several major and minor appearance changes throughout the series, his in-game designs retain several basic characteristics, such as his egg-shaped body, red-black-yellow clothing, pince-nez sunglasses, and large mustache. Robotnik commonly creates machines and robots, including a wide variety of Badniks. Notably in early games, he has also served as a recurring boss, appearing in almost every level piloting one of his created vehicles. His mother is Momma Robotnik.
