Sonic Underground

Sonic Underground aired in syndication in 1999, an animated series spun off from the Sonic the Hedgehog video game franchise following Sonic and his previously unknown royal siblings Sonia and Manic as they search for their long lost mother while battling the villainous Dr. Robotnik. It arrived during a period when Sonic had already appeared in several other cartoon adaptations, which has left it somewhat overshadowed even among dedicated Sonic fans.
