Dr. Eggman is a cruel, ruthless, cunning, egotistical, arrogant, tyrannical and megalomaniacal person. Dr. Eggman has a complete disregard for anyone but himself and is disrespectful in nature, happily mass producing his legion of robots while emitting smog into the atmosphere and pouring oil into the oceans. His I.Q of three hundred gives him a self-important personality, making him a vain and egotistical narcissist. However, this is his greatest weakness, as it can cause him to spend too much time being a blabbermouth and overlooking crucial flaws in his plans. He also has an inability to see his own flaws, considering himself to be the true form of genius.
