Kintobor's experiments with the Kinetic Gyratoscope began when Sonic the Hedgehog stumbled upon Kintobor's Laboratory. On learning of Sonic's innate speed, the scientist was keen to test this and encourage Sonic to run even faster. The events within the Kinetic Gyratosphere would be witnessed twice more by future versions of Sonic, alongside both Porker Lewis and the Chaotix Crew, and later Shadow the Hedgehog.
