A self-centered, selfish, self-proclaimed evil genius scientist. He loves mechs more than three meals a day.

He is incredibly confident and proud, prone to sudden temper tantrums.

With a genius IQ of 300, he is an excellent scientist, but he plots to turn the world into "Eggmanland" without regard for the trouble he causes others. No matter how many times he fails, he never gives up—a man who never learns his lesson. His schemes are constantly thwarted by Sonic, and defeating Sonic is his greatest wish, though deep down, there seems to be a part of him that doesn't entirely hate Sonic.

His real name is "Ivo Robotnik."

Eggman was a nickname Sonic gave him to tease him, but he decided to start calling himself that before anyone could make fun of him, and he continues to do so to this day.

First person: I (Washi - arrogant, old-fashioned).

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 rarely goes out of his way to intentionally hurt others' feelings.

He sometimes takes actions that one wouldn't expect from a villain.

A very lovable character.

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 that connects to a corresponding button on the back.

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

He wears black pants with matching boots; the boots have 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'."

"I, too, have an ambition to make the universe my ideal!"

"It is time to carve this genius's name into history forever!"

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

He always keeps his promises and never betrays others.
