    Comic Adaption

    Ever hear of the magazine Disney Adventures? If so then you may be in for a quaint little surprise....Before there was Archie and Egmont Fleetway, or any of the cartoons, produced was the first TRUE Sonic comic, a 15 page promo for Sonic The Hedgehog 1. Sega Of America was planning to leave its mark on the videogaming world. However, there was only one problem - They needed a mascot. Nintendo had Mario , Atari had Pac Man, so what did Service Games use? Thier answer was a little red, white, and blue Hedgehog named Sonic and his adversary and mortal nemesis - The evil Doctor Robotnik, aka Doctor Eggman! Written And Drawn By Francis Mao, most noteably this is the story that set the basis for the entire Fleetway Sonic Universe and introduced the "Kintobor" concept used in both Archie AND Fleetway....
