Ivo Robotnik

Doctor Ivo "Eggman" Robotnik, or Doctor Eggman, is an evil genius and Sonic's main enemy on the planet Mobius.

## Appearance

Dr. Eggman is depicted as a man with a round and portly appearance, with his torso and head connected in an ovoid shape. He has no visible neck, a bald head, a bright red nose, and a very bushy mahogany mustache. He also has long, almost disproportionately thin arms and legs.

In terms of clothing, Eggman wears a dark blue pince-nez with tinted lenses and glasses with green lenses as his headdress, as well as an elegant red jacket with two square metal buttons on either side of the chest, trimmed in gold. These buttons had white straps that ran down the sides of the coat to identical buttons on the back. The coat also had silver zipper linings on the back, sleeves and front, yellow cuffs and two front panels with large silver buttons. In addition, Eggman also wore white, uncuffed gloves on his hands and a pair of black pants with matching boots seemingly attached to them, with round plates on either side of his ankles and three square plates on his shins.

## Personality

Dr. Eggman is a power-hungry megalomaniac who wanted to conquer the world. He apparently has no problem with kidnappings and threats to harm, however he believes that harming people is actually going too far and he doesn't like harming both people and animals; for example, when the Metarex begin to beat up the captive Chris and Cosmo, Eggman criticizes them for their malicious behavior towards the two of them. Earlier in the series, when the Eggsterminator was brutally beating Sonic, Eggman couldn't watch calmly and even ordered the robot to stop and give Sonic a break. He also has a certain degree of respect and even care for Sonic and his attitude, as in "Trial Time", Eggman not only came to Sonic's aid, but also showed no fear of Sonic's dark transformation and is in fact the one who talks him out of said condition , showing genuine disappointment at his sworn enemy for such cruel actions.

Especially compared to his colleagues, Eggman is more flamboyant, as he is often seen showing off, although he retains some traits of his normal version of personality, such as immaturity. He has a tendency to occasionally make egg-related puns, such as "egg-receptive" or "egg-receptive". He also appears to be a baseball fan, as he once forced his enemies to play baseball against him and his team for the Chaos Emerald.

## Story

Dr. Eggman was born on Earth, but under unknown circumstances was transported to Mobius. Throughout his life, he attempted many times to fulfill his ambitions of achieving world domination, but was thwarted by the heroic efforts of Sonic the Hedgehog and his friends. And it seems that he has long known the same evil genius as Doctor Hell. What’s strange is that he also knew about the existence of the Mycenaean Gods and for him Mazinger Z is quite familiar.

Since Chaos Control emerged from him, he has returned to Earth. However, despite the fact that he was the only member of his own Empire, he began to rebuild it from scratch alone, and at the same time was able to easily deal with other parties to the conflict, not in quality, but in quantity. Gradually, when he begins to fight on the side of the Alliance against the Metarex, he becomes more loyal, although he still dreamed of his own empire.

After Big Concept Change, his memory of past events was erased, causing him to even forget who is Koji Kabuto the Mazinger Z's pilot, was. Although he gradually regained his memories, and then completely returned to the Alliance with a new robot.
