Recap: Sonic, Tails, Knuckles, Shadow, Eggman, and Rouge have banded together and saved the world. For a short time, Sonic and his team have allied with Dr. Eggman's. They do not think that they will fight again, but it is very possible that they may. But for the time being, they are allied, and to celebrate this, Dr. Eggman and Tails have built a theme park. Unfortunately, Shadow had fallen apparently to his death, burning through Earth's atmosphere.

"Man..." said Sonic "It sure is a bummer that Shadow's dead. Just as he realized what his purpose was, and became good... He just..." Just then, Sonic heard a rustling in the bushes. "Shadow?" he said, "Is that you? Are you alive?" But it wasn't Shadow. It was Tails.

"Hey, Sonikuu!" said Tails, "I just finished your Final Rush Roller Coaster! Tell me how it works!" Sonic got into the ride. The car was launched into the air and then hooked onto a rail. After the car came off the rail, Sonic could steer the car to go onto the next rail. Then Sonic heard Tails through the car's radio. "Sonikuu," he said, "You can jump from one rail to another by pressing that green button. It was made from a piece of the Chaos Emerald and some AI equipment that Eggman built. Try it! Sonic pressed the button. Something went wrong. Sonic's car went off the rail and plummeted. He was going down faster and faster. "SONIKUU!" yelled Tails, "NO!"

Sonic had to think fast. "I've done it once with a fake one... Now it's time to try with a piece of a real one! CHAOS... CONTROL!" Nothing happened. The car plummeted down to the ground below. "This is it," Sonic thought, "I'm going to die. But at least... I'll know... that Eggman is on our side now..." The car plummeted to the ground and exploded.

Tails went to the spot of the demolished car. "No... Sonikuu..." You survived before... but now... you ARE gone... I'M SORRY SONIKUU!" Tails went to the spot of the lift behind him, where the cars and passengers would be brought up before they started to ride. Also where the passengers would get out. Also where the crash site of Sonikuu the Hejihogu was. Tails left. "Goodbye Sonic..."

Tails heard grinding on the rails of Final Rush. He turned around. "Sonikuu! Is it you?" He saw a hedgehog silhouette. "Sonikuu! It is you! How did you survive? I'm so glad to see you!"

"I'm not Sonic," said the hedgehog. He stepped forward.

"Shadow!" exclaimed Tails, surprised, "How did you survive the fall to earth, burning as you entered the atmosphere?"

"Well, it kind of hurt at first," Shadow started out, "It WAS fire, after all, but I am the ultimate life form. I survived."

Tails looked away. "S... Sonikuu..." he sobbed, "Now I know you're gone FOREVER!"

"What?" gasped Shadow, "Something's wrong with Sonikuu?" Tails pointed to the explosion spot on the ground. "Just as I realized what my purpose was, and became good... He just... died on me... AUGH! It's times like these that I wish that I weren't the ultimate life form! Everyone dies on me! Sonikuu! Maria! Who will be next? I want to give this horrid fate to someone else and be rid of it!"

Just then, a blast of bright light appeared in front of Shadow. Sonic fell to the ground out of the light. Knuckles walked over. "Whoa... deja vu... Didn't this happen before?"

"But the Chaos Control... It didn't work... How am I here?" asked Sonic.

Shadow was limp on the ground. "Did it work, Tails? Does someone else have my horrible fate? Am I dying? It seems so good to finally be able... to..." Shadow stopped.

"What?" exclaimed Sonic, "What are you talking about, Shadow? You are the ultimate life form! You can't just throw it all away!"

"But... I already did..." Shadow struggled to speak.

"No you didn't!" Sonic cried out. "You were just thrown back from the blast of light that I emitted when I chaos controlled! I guess since it was such a small piece there was a large delay..."

"You sure?" asked Shadow.

"I'm positive, buddy!" said Sonic.

Shadow got up. "You're right! I'm the world's ultimate life form! And nobody DID die on me! You're still alive, and Maria was never alive when I was! Professor Gerald only made me have those false memories! I AM THE ULTIMATE!"

"So..." said Sonic, "Does this mean that you don't want to give up your life?"

"Of course not!" said Shadow. "I have nothing to lose!"

"Hey, Shadow..." said Sonic, "I bet I can make my Final Rush coaster go faster than your Final Chase one!"

"You're on!"
