1999’s Sonic Underground is a weird show to look back on. The 40-episode series is one of the least recognizable in terms of how it adapts the Sonic world, mainly because it doesn’t feel like a Sonic story to begin with. It takes place in a more sci-fi fantasy setting in which Sonic is a prince who, on top of fighting Dr. Robotnik with his speed, incites rebellion as part of a rock band with his siblings. Yeah, on top of that unorthodox setup, Sonic Underground is also a musical, and a lot of its music is pretty fucking bad. The show has a lot of interesting ideas, but its poor execution means it hasn’t maintained the fandom cache of even the other ‘90s animated shows.
