His schemes are constantly thwarted by Sonic, and defeating Sonic is his greatest wish, though deep down, he seems to have a certain fondness for him.

His real name is "Ivo Robotnik."

First person: I (washi - arrogant, elderly)

He usually speaks in an arrogant, elderly tone.

Since his ambition is strictly "world conquest," he rarely resorts to excessive methods like unnecessary city destruction, planetary annihilation, or murder, and he seldom goes out of his way to hurt others' feelings.

He is tall and obese, with a small bald head. He has a distinctive pinkish nose and a bushy mahogany mustache.

His eyes, which are rarely seen, are blue.

He wears a red coat with four gold ingot-like buttons on each side of the chest; each button has a white strap connected to a matching button on the back.

The coat has silver lining on the back, arms, and front, yellow cuffs, and two extensions on the front with large silver buttons.

He wears black pants and matching boots, with circular plates on both sides of the ankles and three square plates on the shins.

"Curse you, Sonic! Just you wait!"

"Indeed! It is I, the world's unparalleled genius scientist, the great Dr. Eggman!"

"Let me give you a piece of advice: those involved in science should not use words like 'magic.'"

He views life as a series of incidents and adventures, living by his own rules rather than society's rules or common sense.

He always keeps his promises and never betrays others.
