Plot Edit

Sometimes, after Sonic defeated Egg Heart with his buddy Miles "Tails" Prower, the entirety of Death Egg Mk. II has been fully destroyed, with the exception of the Master Emerald.

We then cut to Sonic using his propeller shoes. He sees a huge, ruined and completely deserted island. When he reads the sign, the island is known as the Ascquire Island. Knuckles the Echidna, who has a long vacation, searchs where is the island's tropical landscape. Knuckles and Sonic notice that the Master Emerald fell from the sky, from its altar. Knuckles then reveals that Doctor Eggman also taken the Chaos Emeralds, and shattered them into the all-new Special Stages! Sonic covers his face, and sees a giant, sparkly silver armored airship, with a black Eggman's face printed on the side.

Just after the armored airship disappeared, Mecha Sonic took the Master Emerald and placed it in the Skyhigh Skybase Zone. Sonic sets off and starts his adventure through 6 zones and 7 Special Stages. The new addition is that Sonic can hit the Switch Monitor and switch into Knuckles and vice versa.
