Concept and inspiration

In April of 1990, Sega requested a game capable of selling over one million copies and a character to replace Alex Kidd as the company's mascot, as well as to rival Nintendo's flagship character, Mario. Several character designs were submitted by its AM8 research & development department, including an armadillo (who was later developed into Mighty the Armadillo), a dog, a spiky hedgehog (which would later become Sonic the Hedgehog), and a rabbit (intended to use its extending ears to collect objects; these aspects were later incorporated into Ristar). A caricature of Theodore Roosevelt was also one of the possible designs, but it lost to Sonic the Hedgehog, and eventually became the basis for Eggman.

Ivo, the character's first name, is reverse of Ovi, a prefix based on the Latin word for "eggs". Robotnik, the character's surname, is the generic Polish word for a worker. As such, it was used as a title by a number of leftist magazines throughout 19th and 20th centuries.
