It was a calm and peaceful night in Station Square. Sonic was having a little fun hopping from roof to roof, until he saw the flashing police cars roaring by. He followed them to see what was happening.

"Get ready men! Aim...Fire!" shouted a policemen.

Shots rang out and penatrated through the lifeform's body. The bullets fell to the ground and the Lifeform stood unharmed.

"Oh no! Our weapons are useless! All personel, fall back!" said the same policeman.

Just then Sonic had arrived and saw that the Lifeform. He stood in front of it until it attacked.

Sonic then defeated the Lifeform as it formed itself into a puddle of water and started crawling away.

"C'mon ya big drip, where ya goin'?!"

The puddle of water disappeared as it went through to the sewage lid. Sonic stood there without speaking.

"You fool! It's Choas! The God of Destruction!" HA HA HA HA HA HA HA HA HA!!!" Dr. Robotnik said as he laughed.

The next day, Sonic was relaxing in the hotel of Station Square and suddenly saw a plane. It was Tails! The plane was out of control and getting ready to crash.

"Watch out Tails! You're going to crash! Ahhhhh!" Sonic screamed.

As the plane went out of sight, Sonic heard the huge crash of the plane.

"Tails...." Sonic said disappointed, "what am I gonna do with you?"

Sonic made his way towards Emeral Beach to rescue Tails.

As Sonic and Tails venture through Station Square, the Mystic Ruins, and the Egg Carrier, they meet other people along the way and team up and try to stop Dr. Robotnik from getting all the Choas Emeralds and foil Dr. Robotnik's plans from taking over the world again!
