Sonic the Hedgehog must stop the evil Dr. Robotnik from ruining Christmas after Santa Claus disappears.

Sonic, Sonia, and Manic are the children of Queen Aleena Hedgehog, the rightful ruler of Mobius, and are pursued relentlessly by Doctor Robotnik and his bumbling bounty hunters sidekicks, Sleet and Dingo. As infants, the siblings were separated and placed in hiding to fulfill a prophecy made by the Oracle of Delphius that the triplets would grow up to find their estranged mother, overthrow Robotnik, and take their places once more as Mobius' rightful rulers.

A comical, light-hearted and gag-driven adventure series based on the titular character, an arrogant and mischievous yet kind-hearted teenage hedgehog with the power to move at supersonic speeds. Sonic, with his idolizing young friend Tails, regularly oppose the wicked Dr. Ivo Robotnik, his robot henchmen Scratch, Grounder and Coconuts, and thwart their plans to conquer their home planet of Mobius.
