The Kingdom of Acorn, based within the city of Mobotropolis, was at war with an unseen enemy.

The series takes place on Mobius, a planet mostly populated by anthropomorphic animals. The show also inspired a video game, Sonic Spinball, and a long-running comic book series of the same name. Despite its cancellation, a fan following has elevated the series to become a cult hit. A third season was planned, but ABC canceled the show, ending it with a cliffhanger. The program aired for two seasons with a total of 26 episodes on ABC from Septemto December 3, 1994, and continued in reruns until 1995. To distinguish it from other Sonic the Hedgehog media, the series is commonly referred to by fans as 'SatAM', in reference to its Saturday morning timeslot. It features a more dramatic and dark story than the lighter Adventures series, depicting Sonic as a member of a band of freedom fighters battling to overthrow Doctor Robotnik, now a despotic dictator who conquered their home planet Mobius years prior, ruling it as a polluted industrial dystopia. It is the second of DiC's Sonic cartoons, following Adventures of Sonic the Hedgehog. It was story edited by Len Janson and produced by DIC Productions, L.P., Sega of America, Inc., and the Italian studio Reteitalia S.p.A. Sonic the Hedgehog is an animated television series based on the video game series of the same name.
