Dr. Ivo Robotnik is a scientist and the main villain of the Sonic the Hedgehog series. The thing he hates the

Dr. Eggman, or Robotnik in Japanese.

most is the blue hedgehog Sonic.


He is a short-tempered, loud, pompous, bad-tempered and cruel evil genius who is constantly planning to take over the world. However, his plans have always failed thanks to Sonic and his allies. Despite his intelligence, Dr. Eggman is horribly immature, throwing temper tantrums when Sonic throws the proverbial wrench into his plans, and, at times, seems to overlook crucial details in his plans, such as in the opening sequence of Sonic's story in the 2006 video game when he orders his robots to fire on Sonic while he is escaping with Princess Elise, failing to realize that they could possibly injure or kill Elise if they land a direct hit on Sonic. An example of his immaturity is in the ending of Sonic Unleashed, when one of his robots begins to insult him over his constant failures and calls him a loser; Eggman screams "Oh, shut up!!", attempts to kick him only to comically fail, and then chases him through the desert.
