Sonic SatAM
While Adventures of Sonic the Hedgehog had the “every episode is an entry point” structure of many kids’ cartoons, Sonic the Hedgehog (also known as Sonic SatAM in reference to its Saturday a.m. airtime) had a more narrative-driven approach. Adventures had Sonic defeating Robotnik and thwarting his plans during each episode. In contrast, SatAM leans into a darker tone, evolving character relationships, and an interwoven narrative. The cast of anthropomorphic characters is mostly original and hasn’t continued on, so it still feels like looking into an alternate universe truly distinct from the franchise we know today. Though its vibe is a bit different from what Sonic was doing at the time, it definitely feels like a precursor for the series’ darker pivots in the future.
