Sonic Underground (Sonic le Rebelle in French) is an animated series that follows the adventures of Sonic the Hedgehog and his siblings, Sonia and Manic. The cartoon follows a main plot similar to, but heavily reconcepted from, main plot of Sonic the Hedgehog: The Animated Series. The plots are executed using a much less serious format, and the show is aimed at a younger audience than the entire family. The sub-plots of Sonic Underground revolve around the positive-development of younger viewers. The series ran for one forty episode season, and was canceled before any major plots could be resolved.
