Sonic the Hedgehog () is an American-Italian animated television series based on the video game series of the same name. 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. in association with Telecinco. It is the second of DiC's "Sonic" cartoons, following "Adventures of Sonic the Hedgehog". 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. 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.
