Dr. Eggman

Dr. Ivo Robotnik (ドクター・ロボトニック Dokutā Robotonikku?, lit. "Doctor Robotnik"), better known by the alias Dr. Eggman[1]  (ドクター・エッグマン Dokutā Egguman?), is a fictional human character from the Sonic the Hedgehog series. He is the arch-nemesis of Sonic the Hedgehog and the primary antagonist of the franchise. As an obese scientist with an IQ of 300 who dreams of dominating the world, his constant plots to create his Eggman Empire are endlessly thwarted by Sonic and his friends.

While the doctor's plans initially consisted of building up incredible armies by turning animals into robots and using them to dominate the land, Dr. Eggman's schemes have since branched into much more global threats as he built war machines, used nuclear devices to threaten entire nations, and even relied on mythological and ancient deities bent on destruction to achieve his goals. Eventually, the mad scientist has gone as far as to target the entire universe and cooked up schemes to control time and space itself.

While all these plans end in failure thanks to the continued efforts of Sonic and his friends, the mad doctor somehow is always able to slip away from certain death or imprisonment and escape at the last moment, making him a constant threat to the universe and a thorn in Sonic's side.

Early Life
In childhood, the young Robotnik looked up to his grandfather, Prof. Gerald Robotnik as a hero, and believed him to be a great man who had done his best to help mankind. Thus the doctor decided to follow in his grandfather's footsteps and became a scientist, as well as pursue a teaching degree (apparently because he liked telling people what to do). However, he became obsessed with the idea of an entire world under his rule, and using his unmatched genius, began his plans.

At some point after setting out on his quest for global domination, Dr. Robotnik met Sonic the Hedgehog. While the nature of their meeting is unknown, the two of them eventually became rivals, with Sonic proving to be Dr. Robotnik's greatest enemy. After their meeting, Dr. Robotnik made several attempts to conquer the world, but at every turn, his plans were laid to waste by Sonic.

After years of countless failures....
As many would already had known, Eggman, while being a very well known villain, hasn't exactly been, even remotely successful. He tried robots, anicent monsters and powers, and pretty much often the same stragity with them every time. He even tried to alter time, and that bit him very badly in the ass. Eventally, Eggman was met with a disguised Nega-Zeus that offered him a chance to finally be great then Sonic indiffently. Eggman accepted, and was told everything The Guild of Thunder is dedicated to do. He is like the Captain Hook of the Main council, very critical torwords the heores their up against and quick to be made at a certain Witch from Rareware. He used to be the owner of Team Nefarious' own Scratch and Grounder, but he forsaked them cause "He was going through a phase at the time and grew out of it", implying he perfers to avoid his "surreal pasts" beyond the video games.
