Doctor Eggman (Sonic Boom)

"I'll be back! With a new robot! Who has an accurate name! And super laser eyes! And he'll feed me ham! Evil ham..."

- Doctor Eggman, "The Sidekick"

Doctor Eggman is the main antagonist in the Sonic Boom series. He is a human scientist and arch enemy of Sonic the Hedgehog, who seeks to conquer the world and enslave the population, and plots evil schemes against Sonic and his crew from his evil fortress.

Concept and Creation
When developing the character designs, the designers went with a very formal, military-esque attire for Eggman to emphasize his vanity and concern for his own and his robots' appearances, which is an attribute quite fitting for villains.

Appearance
Unlike his main series counterpart, which is more round on the lower portion of the torso (the stomach), Dr. Eggman's torso is more round at the top, like an upside-down egg, and he has more smooth, yet still broad shoulder. His mustache is also shorter and smoother, and a bit darker, and his legs are slightly shorter with significantly smaller feet.

Compared to his main series counterpart, the doctor's outfit has been dramatically redesigned, having been given a more militaristic appearance. He still wears a red jacket with yellow cuffs, blue pince-nez glasses, white gloves and a set of grey goggles with green lenses on top of his head. However, his goggles are slightly thicker and smaller, and his jacket has a front flap that is attached to one of the jacket's buttons and two flap hanging from the back. He also carries a device on his right wrist and wears grey pants and a pair of black boots with high rims.

Sonic Boom: Rise of Lyric
Eggman is set to appear in Sonic Boom: Rise of Lyric as a secondary antagonist, since Lyric the Last Ancient is the principal antagonist of the game, and the two of them will have an uneasy partnership.

Archie Comics
On a bright day on the beach, Eggman was facing Sonic in battle with his Giga-Mech, but was unable to get him. Shortly after, Tails, Knuckles and Amy came to Sonic's aid, and besides from stomping Knuckles into the ground, he was outmatched. In the end, Eggman was beaten when Sonic and his friends attacked his mech at critical points, making it collapse and Eggman retreated to his lair. Meanwhile, Team Sonic had to deal with the Rock-cyborg, a robot planted beneath Tails' house by Eggman. The next day, as Eggman was having his breakfast served, Knuckles arrived at his doorstep and asked if he wanted to team up.

Personality
Eggman is a short-tempered, raucous and pompous evil genius, and has all the qualities of a classic villain. He looks, talks, and dresses like a bad guy and possess the psychotic belief of self entitlement of enslaving the world, the destruction of his enemies or both. Because of his constant desire to enslave the world, Dr. Eggman will do whatever it takes to achieve his goals, even if that means teaming up with an enemy more powerful than he is.

Despite his intelligence, Eggman is immature and hates when Sonic gets his name wrong and/or gives him nicknames. He is also self-deluded and somewhat of a doofus, not using necessary parts for his robots in the belief that they are spare part, geeking out with Tails in the midst of a battle, and sneaking in on his enemies to plant a robot rather than using the opportunity to attack them in their sleep.

Eggman has an extreme hunger for power, and desires attention, adulation, and a little respect. While things might not always work out for him initially, he is always working behind the scenes to get the upper hand and come out on top.

Orbot and Cubot
Orbot and Cubot are the closest things Dr. Eggman has to friends. While they are loyal to him, they are not perfect and they have a tendency to say things he does not want to hear.

Trivia
