Knuckles' Story

The story begins with the Egg Carrier flying over to Angel Island. Eggman with Orbot and Cubot is scheming on his latest plot to take over the world and that is to release a mysterious creature from the Master Emerald. Following the instructions of the ancient tablets, Eggman plans to use the chants to release the beast within the Master Emerald.

Resting on the shrine of the Master Emerald is Knuckles who is thinking over his duty to guard the Master Emerald, he is disturbed by a shattering Chaos next to the shattered Master Emerald. Unaware that this is Eggman's doing, Knuckles assumes that Chaos is behind the shattering of the Emerald and goes on to attack it. However, the beast blindsides him with a punch and escapes, and suddenly Angel Island falls into the sea next to the Mystic Ruins.

Morning time came, and Knuckles arrives in Station Square to find the pieces of the Master Emerald.

Confident in taking on Chaos 2, Knuckles is ready to fight.

Later, Knuckles is sent back to his time...right in front of the altar. He remembers to restore the piece of the Master Emerald. He puts the Emerald shards to its rightful place. It turns out that only 85% of it is restored, and the last three shards are on the Egg Carrier. Knuckles has no idea where the flying fortress is.
