Doctor Robotnik, formerly known as Julian, is the main antagonist of the Sonic the Hedgehog television series. He is a human and the arch-enemy of Sonic the Hedgehog. Initially serving as the head of the King of Mobotropolis's War Ministry, Robotnik eventually organized a coup that allowed him to seize power over Mobotropolis, which he renamed as "Robotropolis", becoming the dictator of Mobius. Through the use of roboticization, Robotnik would turn the majority of the world's population into his mindless Worker-Bots while seeking to spread his pollution and destroy the environment. He is assisted by his conniving nephew Snively, his massive army of Swat-Bots, and his pet robot chicken Cluck. His rule is opposed only by the Freedom Fighters, particularly Sonic the Hedgehog.
