The Death Egg, Dr. Ivo Robotnik's space station, has once again crashed on Angel Island after the events of Sonic the Hedgehog 3. Robotnik needs power the Chaos Emeralds to power it up again, and because of this, Sonic and Tails have to find the Chaos Emeralds before him so they can stop his plans of world domination. However, Knuckles, the guardian of Angel Island and the Master Emerald, was tricked by Robotnik into thinking that Sonic and Tails are after the Master Emerald, so he is equally determined to stop the duo. But while all 3 are going round with each other, who's gonna stop Robotnik? Written by
