Doctor Eggman is a human with an amazing IQ over 300. He uses his scientific genius and robotics expertise to create weapons and gadgets in his bid to take over the world. However, Eggman’s schemes are foiled at every turn by Sonic and his friends. As countless of his plans were ineffective, he has recently become a little more insane than the smart, calm, and evil man he used to be. He is very short-tempered. Eggman is also very arrogant and narcissistic, and even many of his robots and machines bear his likeness to some degree.
