A subplot between Ivo Robotnik and Agent Stone in Sonic the Hedgehog 3 is surprisingly emotional. The story of Sonic the Hedgehog 3 follows Sonic, Tails, and Knuckles as they get recruited by the Guardian Unit of Nations (GUN) to fight Shadow the Hedgehog after he escapes from Prison Island in Tokyo Bay, Japan. However, Shadow proves to be far too formidable of an opponent for Team Sonic, which leads them back to Ivo Robotnik, the villain from the first two Sonic movies.
