answer:Dr.Robotnik(Satam)
Dr. Julian Robotnik is the absolute ruler of a roboticized Mobius, and is a far more chilling incarnation than usual. A ruthless, ambitious backstabber with a series of treacherous moves to his count in the name of self-interest, Robotnik's first betrayal was his sealing of the wizard Naugus in the Void. Later becoming known to the King of Mobius, Robotnik became instrumental in the King's own military victories before deciding to take over Mobius himself. Staging a coup d'état and overthrowing the King from Mobotropolis, Robotnik stole the technologies of the Roboticizer from Charles Hedgehog, and used it to forcefully convert almost all of Mobius into a polluted dystopia. Reducing all of Mobius's inhabitants to his robotic slaves—which they morally object to and fight against—Robotnik made fierce enemies with Charles's son, Sonic, and the rest of the Freedom Fighters. Robotnik would demonstrate his psychopathic nature again and again, attempting to kill, torture, or otherwise roboticize the Freedom Fighters, happily willing to jeopardize the ecosystem in doing so. Robotnik also coldly abuses his own minions, his diminutive, weak-willed nephew Snively among them, and condemns them all to die for the sake of his own life in the finale. An emotion-deficient fear-monger with nary a comedic quirk to his name, Robotnik proved one of the most vicious incarnations of Robotnik seen in the franchise.unlike most Sonic villains,he almost turn sonic into a robot
