Sonic R is the only appearance of the characters Metal Knuckles and Tails Doll, and the only playable appearance of Egg Robo.

Story
Sonic and Tails are enjoying a little time off from adventuring. The trip they have planned will be a nice, relaxing vacation. Or so they think...

Tails spots a huge sign alongside the road they are currently traveling on. It is a recruiting advertisement for the World Grand Prix. "Sonic! Sonic! Look! There's going to be a huge race with all the best racers in the world! What a great opportunity for you to show your speed and compete with the other great runners!"

Sonic thinks for a moment. He's the world's fastest runner, but participating in races is not really his interest. Something on the sign, however, catches Sonic's eye. Dr. Robotnik, Sonic's arch-enemy, is participating in the race. Sonic races off into the distance. "Wait Sonic! Wait for me!" Tails shouts to his friend.

Miles above the sign, a spy satellite focuses on Sonic and Tails. Dr. Robotnik snickers in delight. "Now that you have fallen into my trap, Sonic, I will finally have the Chaos Emeralds, and beat you at the same time. With my new hover machine, and these new robots..." Dr. Robotnik looks to his left, and a row of gleaming eyes gaze back at him. "Nothing can go wrong! Hahahahahahaha....." Little does Sonic know that Dr. Robotnik has learned of the location of the Chaos Emeralds.

Sonic is not the only one who will be racing with Dr. Robotnik. Sonic's rival, Knuckles, has learned that Sonic will be participating in a very important race. Knuckles never turns down a chance to be around Sonic when the action starts.

Amy will be there too. After secretly following Sonic to his vacation spot, she joined the race, hoping that winning will impress him.
