In the comic-book series, Sonic was just a usual hedgehog until he was discovered by 'Doctor Ovi Kintobor', who sees that Sonic can run quite quickly. Sonic is put on a treadmill in Kinobor's lab, and eventually allows him to run so fast that he exceeds the speed of sound. Sonic turns blue and begins to help the doctor, until an experiment to trap all the evil of the world in the Chaos Emeralds backfires, thus creating Doctor Ivo Robotnik, the main protagonist of the series. It is unknown where, exactly, this takes place. We only know that this event occurs on the planet Mobius.
