Sonic Underground synopsisEdit
In a parallel universe similar to the SatAm version, the evil Dr. Robotnik has conquered Mobotropolis and turned it into Robotropolis. Queen Aleena, it's ruler, took her three children named Sonic, Sonia and Manic and went into hiding. A prophet called the Oracle of Delphius informs the queen that the only way to defeat Robotnik is to give up each of her children separately, so that they would grow up and meet with each other to overthrow Robotnik, reunite with their mother and regain their rightful place as rulers.
