Dr. Robotnik has finished his latest creation Hyper Metal Sonic in an attempt to end Sonic the Hedgehog. However, according to Robotnik, the one thing he needs to complete Metal's AI is to infuse it with Sonic's life data. On a lonely island located in Land of the Sky, Sonic is relaxing on a beach chair and listening to radio outside the ruins of a crashed Boeing 747 and USS Enterprise, which serves as his house. Tails comes out to test his new, jet-propelled body-board, asking Sonic to give it a try, but Sonic declines due to his dislike of water. While testing the body-board, Tails collides with Old Man Owl who is flying around the island in small aircraft. Afterwards, Old Man Owl gives Sonic and Tails emergency news from the President, who wants to meet Sonic right away. As they arrive at the presidential house, Sonic and Tails encounter Dr. Robotnik and his robotic guards who hold the President and his daughter, Sara, hostage. Sonic and Tails enter the Land of Darkness, Sonic and Tails would face off Crawlton and a swarm of Buzz Bombers, Sonic and Tails get attacked by Metal Robotnik's glue projectiles which get Tails stuck on a fence. Before Metal Robotnik can finish Sonic. Knuckles enters the battle and frees Tails from the glue projectile. Sonic, with help of Tails and Knuckles, manages to destroy Metal Robotnik completely. Eventually, the trio would come across Metal Sonic, who is powered by Sonic’s DNA data. After taking down Metal Sonic, the trio would rescue everyone and Robotnik plans fail once again.

Sonic: Well everyone we did it.

Tails: Yeah we did. We rescued everyone and saved the day. :D

Knuckles: Glad I was able to step in myself since you both looked like you were having trouble with the battle.
