A fat old guy from the sonic video game series that is always making robots. He is most likely to 1), get an evil plan, 2), attempt to enslave some legendary power that only he's ever heard of, 3), lose control of said power, and then 4), exclaim that he can't believe he's lost control of said power... then get owned by sonic.
Dr. Eggman is at it again, this time he tried to enslave satan.

His full name is IvoEggmanRobotnik. Dr Robotnik has an IQ of 300 which he uses to kill animals and attempts to drill a hole in Sonic’s forehead. Sometimes he gets creative and once even shot up an entire forest for shits and giggles. He then spent 55 minutes laughing about it and also he finds glee in emaciating animals by shoving their asses into cages and locking them. He also eats 299 eggs every day to keep his Eggman size.
Sonic: Dr Eggman, you won’t get away with this
Dr Eggman: jokes on you fucktard I already planted a bomb in the orphanage.

Sonic: not if I believe in my friends
*gun shots*
Dr Eggman: sonic is no more

Something that you should never ever look up.
Person 1: Don’t look up Dr Eggman Blue
Person 2: Ok
Dr. Ivo "Eggman" Robotnik, more commonly known as Dr. Eggman, is the main antagonist of the Sonic the Hedgehog video game series. Sporting an IQ of 300, the Doctor's ambition is to take over the planet and establish the Eggman Empire. His plans have been so far thwarted by Sonic & friends, or Robotnik's own plans backfiring on him. In the past Robotnik would rely solely on his robots, called Badniks, to defeat Sonic and aid in his gathering of the Chaos Emeralds, which are seven extremely powerful gems, to conquer the world. More recently however, the Doctor has deviated from using armies of robots and instead attempts to unleash various mythical beasts and/or gods to help in his takeover of the planet. These sorts of schemes are the ones to backfire, as Robotnik can't seem to control what he has awoken for very long. The Doctor will then usually choose to flee or assist Sonic & friends in defeating the monster.
