Though the character was rejected, the concept was revisited by the development team, which wanted an egg-shaped character to be featured in Sonic the Hedgehog. The man with a mustache was the second favorite, losing to a hedgehog character that would become Sonic the Hedgehog. There, he went to Central Park, where he would ask locals for their opinions on them. Eventually, Ohshima went on vacation to New York, taking sketches with him. However, it was stated that the resemblance to Roosevelt was unintentional, the character taking inspiration from other characters instead. Amongst the proposed designs was a mustachioed man wearing pajamas that bore resemblance to Theodore Roosevelt, drawn by Naoto Ohshima. Several character designs were submitted by its AM8 research and development department. Sega had previously used Alex Kidd as their mascot, but because he was considered too similar to Mario, he was deemed unsatisfactory. They wanted a character to rival Nintendo's flagship mascot Mario Sega president Hayao Nakayama in particular wanted a character as iconic as Mickey Mouse. In April 1990, Sega requested a game that involved a mascot for their company. This character would later be slightly modified to become the main antagonist of the game, Dr. One of the concepts for the hero of what eventually would be known as Sonic the Hedgehog. Eggman's immature character and self-centered thoughts have led to evil deeds, making him the most dangerous threat to ever appear in the universe. While all of these plans end in failure due to the continued efforts of Sonic and his friends, the mad doctor is somehow always able to slip away from certain death or imprisonment and escape at the last moment. At times, Eggman has even gone as far as to target the entire universe and hatched schemes to control spacetime itself. His ambitions and schemes ever growing, his plans have varied from using Animals to power his robots to making incredibly dangerous global threats that have involved building war machines, using doomsday devices to threaten entire nations, and relying on ancient mythological deities or eldritch abominations bent on destruction, all in the name of achieving his goals. Never discouraged by his defeats, Eggman is always able to come up with a seemingly endless supply of plots to make his ambitions a reality.

For all his brilliance though, his plans are constantly foiled by his arch-nemesis, Sonic the Hedgehog, and his friends. Eggman dreams of conquering the world to establish a global empire to build his utopia, Eggmanland. He is a human scientist who boasts a remarkable IQ of 300 and a passion for machines. Now witness the beginning of the greatest empire of all time! Hahahaha!ĭoctor Ivo Robotnik ( ドクター・イヴォ・ロボトニック, Dokutā Ivo Robotonikku ?), better known by the alias Doctor Eggman ( ドクター・エッグマン, Dokutā Egguman ?), is the main antagonist of the Sonic the Hedgehog series. Hahaha! Citizens of earth, lend me your ears and listen to me very carefully! My name is Doctor Eggman, the world's greatest scientist, and soon to be the world's greatest ruler.
