Doctor Ivo "Eggman" Robotnik, is the anthesis of Sonic the Hedgehog, Wanting to rule the world the world and see him and his image, Eggman is a Egotistical, Cunning, and Malicious Enemy with a recorded IQ of over 300, Whilst he can act childish at times, he has shown time and again that he can be as Evil as necessary, whether that means Deceiving allies or tricking enemies, he has his way around every Scenario, whether that be by his own qualities, or his machine's qualities.

How Eggman should sound: Eggman can sound like either interpretation of the character, from the Adventure era/4kids era. While Eggman can be somewhat goofy, he can also be just as terrifying, he should be a mix of formidable but also light hearted at times. He should mainly sound deeper Malicious, Cunning, Intelligent, and When he's almost won He should gloat to himself and act fairly egotistical, But when he's on the back ropes, he should sound desperate, tired, defeated, and in some cases he should even shriek in fear and or try to run away.

This is a lead role for Sonic onset Adventure.
