Eggman Empire (Sonic the Hedgehog)

The Eggman Empire also known as the Robotnik Empire or the Dr. Eggman Empire is a political body that appears in the Sonic the Hedgehog series. It refers to the totalitarian regime of scientists and robots ruled by the infamous Dr. Eggman that seeks to lay claim to the entire globe. Although it has occasionally been established, the Eggman Empire has never managed to hold its ground, and merely refers to the territories Eggman has claimed and plans to claim. Its main enemies are Sonic the Hedgehog and his allies, and the United Federation, though other factions have opposed it as well.

n his bid to establish the Eggman Empire as the world's dominant superpower, Eggman continuously seeks to establish Eggmanland (エッグマンランド Eggumanrando?) (also referred to as Robotnikland), a city from where the doctor plans to spread his rule from.= Every time Eggman has hatched an evil plan for the Eggman Empire though, Sonic and his friends have been there to stop him.
