Sonic The Comic

Sonic The Comic was a fortnightly publication of comics featuring Sonic that ran in the UK, published by Fleetway (later a division of Egmont), although localised publications of the comic were temporarily sold in European countries. Interestingly, this comic used elements of the original Sonic bible document, which was never referenced by any other medium (outside of the UK book Stay Sonic).

Overview
Sonic is a denizen of the planet Mobius, and is its self-imposed heroic figure, fighting against Doctor Ivo Robotnik. Sonic is treated with high regard from the other inhabitants, whereas Robotnik is treated with disdain.

Backstory to Robotnik
Some time earlier, Sonic, still a brown hedgehog, burrows into the laboratory of Dr. Ovi Kintobor, a kindly fellow who wishes to finish a machine known as the Retro-Orbital Chaos Compressor (ROCC), which will use rings to condense the planet's evil into six of the seven chaos emeralds, so that good will prevail. Kintobor recruits Sonic to find them, whilst also taking measurements of Sonic's speed.

One such experiment involved Sonic running in a Gyratoscope to test his speed using new friction-reducing sneakers. Sonic's high speeds not only destroyed by the Gyratoscope, but transformed his figure from spiky and brown to streamlined and blue.

The next day, Kintobor, offering to make Sonic food, finds a rotten egg in his fridge. Planning to put salt on it, he trips over a wire, and slams into the ROCC. As the machine explodes, the evil energy and the rotten egg morphs the kindly scientist into the portly Dr Robotnik, the complete polar opposite to Kintobor in every respect (including name).
