Well, this is my first story ever on this site. I was inspired by and have borrowed some ideas from JudasFM's stories based off of the second and third Sonic games. Enjoy.

Edit: It has come to my attention that some people are confused by the character's ages in this story. Well, simply take the ages of the new generation characters and subtract by 2 to get the ages in this story, therefore, Sonic is 13, Amy is 10, Tails is 6, Knuckles is 14, and so on and so forth. This was done for two reasons; one, because It helps merge the two generations, and two, It was about two years before Sonic Adventure when I first played sonic CD ;).

It was finally the long expected day on South Island. The dwarf planet dubbed, The Little Planet, was soon to re-enter Mobius' atmosphere. Only returning once every 10 years, The Little Planet's atmosphere and climate was nearly identical to Mobius's, ideal for colonization. People from all over Mobius would flock to South Island to enjoy the Planet Festival that was held there, visit the planet, and to join the colonies. The colonies were already well established, even to the point where the traditional 7 zones of an island had been established. The many amazing sights to see on the planet had many people visiting the planet and even staying on during it's venture back into space. In order to keep the planet from leaving while tourists were still on board, a massive chain would attach the planet to South Island, preventing it from leaving till all the tourists had left.

While the Cosmic festival was still in it's beginning stages, three rather famous Mobians were on their way to the party.

"I don't know how on Mobius you convinced me to leave my island AND the Master Emerald to come to a stupid party." Knuckles grumbled to Sonic as they walked towards the small desert between Green Hill Zone and Marble Zone where the planet would come closest to Mobius.

"I highly doubt anyone will miss seeing the Little Planet's return to Mobius to fly all the way up to Angel Island and try to steal the Master Emerald." Sonic replied " And if you weren't so stubborn, we could have made it to the festival earlier."

"Yeah!" Tails put in "Besides those traps and cameras I set up'll stop any thieves who try to swipe the emerald."

"I still don't trust those fancy gizmos." Knuckles muttered.

"You'll enjoy the festival, trust me. It only happens every ten years, so it has to be awesome."

"How would YOU know? You were only three when the last one happened."

"True, but Mighty was six, and he remembered enough to tell me. He said it was awesome, there were huge rides, lots of food, and you could ride up a space elevator and look around the zones up on the planet."

"Big whoop…" Knuckles muttered. "I don't need to come to South Island to see the planet. My ancestors could see the planet from Angel Island just fine. Besides, if I wanted rides, I'd just go to Carnival Night Zone."

"Ah hush up." Sonic replied, "We're here!"

"Wow!" Tails exclaimed in awe of the awesome sight before them. There was a standard fair ground with rides and food kiosks, but there was also a huge stage for concerts and other entertainments, many booths where people from all over Mobius would sell merchandise from their home zones, and smack in the center of the festival, the massive chain that connected Little Planet to Mobius. And even Knuckles was silenced by the impressive sight of the Little Planet's enormous bulk floating over the festival.

"I heard it's even more impressive at night when all the lights are on." Sonic remarked as they neared the entrance.

"Gee Sonic, really?" A female voice from behind them said. Upon hearing the voice, Sonic froze completely stiff.

"No. Please no." Sonic moaned. "Not her. Not now."

"Hi Amy!" Tails called, oblivious to Sonic's misery.

"Oh Sonic, I knew I'd find you here." Amy Rose said as she locked him in an awkward hug, (Much to the amusement of Knuckles) "I knew you wouldn't miss something this big."

"Yeah, you were right." Sonic said as he franticly gestured to Tails to get her off of him. But Tails just innocently stared and Knuckles was too busy trying not to burst with laughter. "Um, can you please let go now?" Sonic asked.

"Will you promise not to run away?" Amy asked.

"Oh sure." Sonic said, crossing his fingers. As soon as Amy released Sonic, He took off at top speed, leaving behind a bewildered Tails, a hysterical Knuckles, and a furious Amy.

"Ooohhh, Sonic!" She grumbled "I should have known he'd do something like this." As she stormed off to the fair to find him, Knuckles finally recovered enough to start off himself.

"Maybe coming here wasn't such a bad idea after all." he chuckled to himself as Tails tagged along behind.

"Why was Sonic in such a hurry to get away from Amy?" Tails wondered out loud. "I like Amy."

"You'll understand when you're older." Knuckles said as they entered the fair grounds. "Now then, what should we do first?"

"I'm riding the roller coaster" Tails said with decision.

"Well, I suppose, but don't be disappointed if they don't let you ride because you're not tall enough."

"They've gotta let me ride cause I helped Sonic save the world, TWICE."

"I had a hand in that second one you know." Knuckles pointed out.

"Yeah, by dropping us into ravines and trying to drown us and turning off lights and throwing bombs at us and…"

"Yeah yeah, whatever…" Knuckles muttered.

As they neared the rollercoaster, Knuckles noticed three familiar faces in the line ahead. "Hey! Espio, Vector, Charmy!

"Well now, If it isn't Knuckles the Echidna. Good to see you again." Vector said with a smile. "What are you doin' here?"

"Eh, Sonic dragged me down here to see the planet. What are you guys doing here?"

"We were hired as festival security due to our work with you and Mighty protecting Carnival Island." Espio said.

"Yeah!" Charmy exclaimed, "And for our work, we get free food 'n rides!"

"Cool!" Tails said. "If they let you ride, I'm definitely old enough."

"Ah," Vector said, "You must be Tails. Knuckles told us a lot about you and Sonic. He said you're quite the little ball of energy."

"Trust me, He's nothing compared to Charmy." Knuckles chuckled.

"And what's that supposed to mean?" Charmy said huffily.

While Espio and Vector tried to calm Charmy down, Sonic was trying to get to the concert stage without being seen by Amy.

"It figures, The Underground are here live, and she keeps me from seeing them." He muttered as he tried to take routes he thought she thought he wouldn't take. As he was sneaking around, he heard a commotion near where the chain connected the Little Planet to South Island. He hurried over, he saw the cause of the commotion. Doctor Ivo Robotnik with a small army of robots had burrowed under the chain and had taken out the security around it.

"Robotnik!" Sonic exclaimed as he dashed towards his foe.

"Ah, Sonic, fancy meeting you here." The doctor chuckled as his robots moved in towards the massive chain "I should have known you wouldn't miss something as big this."

"I should have thought the same, but you didn't answer my question, what are you doing?"

"I'm here for the Little Planet's chain of course." Robotnik grinned.

"You can't do anything to it. It was designed to be completely unbreakable." Sonic shot back.

"My dear Sonic, whoever said anything about breaking it?" So saying, Robotnik pushed a switch on his dashboard. The robots surrounding the chain began to fire lasers to weld the chain firmly to the device that released the chain when it was time for the planet to leave. "Now the planet cannot escape until I'm finished with it!" he laughed.

"What would you want with the Little Planet?" Sonic questioned "There's nothing of value on it."

"That's where you're wrong my spiky blue friend." Robotnik said turning his Eggmobile to face the planet. "There are seven objects of great value on it."

"What?" Sonic said, startled. "I put all seven of the Chaos Emeralds back in the Special Zone."

"Did I ever say I was after the Chaos Emeralds?" Robotnik laughed as he and his robots began flying towards the planet's surface.

By this time, A large crowd had gathered around the chain. Knuckles, Tails, and the Chaotix just arrived.

"Sonic! What's going on?" Knuckles asked as they ran up.

"Looks like Robotnik's back"

"Aw man." Tails complained, "Now I'm never gonna get to ride the roller coaster."

"Never mind that." Vector said. "We've gotta figure out what he's up to. Chaotix! Let's look for clues."

"We should probably head up to the planet and try to see what he would want up there." Espio said.

"Then let's go Go GO!" Charmy said, buzzing with excitement.

"Wait!" one of the security guards said "Robotnik damaged the elevator so no one could follow him."

"No biggy." Sonic said with a shrug. "We can take the Tornado."

"And we can rent a plane." Vector said.

Then as the crowd cheered them on, The two groups of heroes set out on their quest to save the Little Planet from Dr. Robotnik's latest evil scheme.

Well, That's it for the prologue. Please read and review. I will be more than happy to answer any questions you might have.
