Once again creating a completely different origin story, DiC choose to produce an animated series having nothing to do with either of their previous efforts. Born into a royal family, Sonic and his two siblings, Manic and Sonia, are separated from their mother because of the intervention of Dr. Robotnik, who overthrows the kingdom. Maintaining his rule by appealing to the upper class, Dr. Robotnik's role as dictator forces the three hedgehog siblings to be raised by other families, and are only reunited once they reach their teenage years. Sonic, Sonia, and Manic then decide to form an underground rock group, appropriately named Sonic Underground. They use the band as a front to gather intelligence and to one day reunite with their mother, Queen Aleena, and overthrow Dr. Robotnik once and for all.
