Metal Sonic was created by Dr. Eggman to destroy Sonic, but always ended up failing. He tried one last time. He transformed into the Metal Overlord, a combination of Chaos, Team Sonic, and Shadow the Hedgehog's data, and took on Super Sonic. Once again, he failed at this task. He fell to the deck of the Egg Fleet.

After the last defeat, he decided to move to the Mushroom Kingdom. Metal Sonic is hiding somewhere, with a computer. He is storing energy, hoping he can take on Mario and defeat him. One day, Mushroom Kingdom will suffer an attack worse than Bowser. They will face... METAL OVERLORD.
