Plot

To try and steal six chaos emeralds located in South Island, Dr. Ivo Robotnik (the villain) has trapped the animals living on South Island in robots. The player is controlling Sonic, who's goal is to free the animals and obtaining the emeralds himself.

If you have collected all the emeralds, you will be rewarded with a good ending. If you do not collect all of the emeralds, the ending will show Robotnik juggling the emeralds that you have not collected.
