Robotnik[12] (ロボトニック[12] Robotonikku?), better known by his nickname Doctor Eggman[12] (ドクター・エッグマン[12] Dokutā Egguman?), is the main antagonist of the anime series Sonic X and its comic series published by Archie Comics. He is a mad scientist whose ambition was universal domination and the establishment of his Eggman Empire. He is aided in his schemes by two sidekick robots, Decoe and Bocoe, his messenger Bokkun, and his arsenal of ruthless robots and high-tech terrornauts.[13] Despite his efforts, though, Eggman's plans are always put to a stop by his arch-nemesis, Sonic and his friends.
