Danny, Frances, and Helen were at school playing basketball.

"No way! Two points!" students said.

The basketball landed through the net. Nearby, Mr. Stewart was secretly contacting his superiors.

"This is Chalkboard Charlie calling Homeroom. Chris Thorndyke is still absent from school." he said when the basketball stopped rolling when it collided with his right leg.

"Get the ball, Frances." Danny said.

"Mr. Stewart? Can you throw me the ball, please?" Frances asked and he picked up the ball.

"Hey, Mr. Stewart! Why don't you come and play?" Danny asked.

"Uh... me?" Mr. Steward said.

"Yeah, it'll be fun!" Frances said.

"All right." he said then took the ball and dribbled it toward the net.

Then he dunk the ball through the net.

"Right in the net! That was an awesome shot, Mr. Stewart!" Danny said.

"Well, I was an alternate in the practice squad back in college..." he said and Helen giggled. "Did I... say something funny, Helen?"

"I was just thinking that I'm happy we got you as our teacher." Helen said.

"Really?"

"We wasn't sure about you at first but you're cool." Danny said.

"Thanks, Danny."

Meanwhile Chris was at Tails workshop searching for him.

"I thought Tails and Sonic would be here in the workshop. I wonder where they are. Maybe they took the X-Tornado out and I guess I just missed them. I can't wait to show them what I got! Sonic's gonna be really proud of me when he sees that I found a Chaos Emerald!" Chris said.

Meanwhile Sonic and Tails were walking together. Then they spotted Knuckles, who had his back to them.

"It's Knuckles." Tails said.

Knuckles smirked standing over an unconscious Eggman.

"Eggman." Sonic said.

"Hm." Knuckles said and Sonic and Tails appeared.

"What'd you do to him?"

"Nothing. I found him this way."

Tails poked Eggman with a stick to see if Eggman was alive, and was surprised when Eggman sat up.

"Whaah! He's alive!" Tails said.

"Of course I am." Eggman said.

"What happened?" Sonic asked.

"Chaos turned against me."

"How come?"

"Because... it wants to use the power of the Chaos Emeralds all for itself."

Knuckles reached for Eggman's throat.

"Tell us where Chaos is or else!" he said.

"Take it easy, Knuckles!" Sonic said.

"How dare you threaten me! I'd love to teach you a lesson, but unfortunately I have to fly!" Eggman said and mysteriously rose into the air.

"He's getting away." Tails said.

It is revealed that Eggman is being airlifted by a hot-air balloon manned by Bocoe and Decoe.

"Okay, start reeling him up." Decoe said.

"The winch is jammed!" Bocoe said.

"We can pull him up ourselves."

"No way. All that weight will burn out our motors."

"Don't just leave me hanging here like a salami!" Eggman said.

"Try not to get agitated. The cable could break." Decoe said.

"Just enjoy the ride." Bocoe said.

"There's not time to lose. My plans for world domination depend on Chaos. We have to track down that renegade right away!" Eggman said.

"Roger!" Decoe said.

Eggman cries out as his hench-bots fly him away.

"If Eggman was telling the truth, we have to find Chaos fast and stop it. The second it gets a hold of all seven Chaos Emeralds, it will become too powerful to defeat." Knuckles said.

"You're right." Sonic said.

Suddenly a bright light enveloped Sonic and Knuckles.

"What's goin' on here?" Sonic said.

They studied their surroundings and saw they were at a vision.

"Quiet... I've been here before. We're back in the past." Knuckles said.

They see Chief Pachacamac and his clan in front of the Master Emerald shrine. Tikal and several Chao block the way to the temple.

"Tikal, the clan needs those seven Emeralds. It is the only way to protect ourselves from our enemies." Pachacamac said.

"But taking the Emeralds isn't the way! Please stop! You'll regret it forever!" Tikal said.

"The clan has made its choice, and we'll seize the Emeralds now. Warriors, attack!" he said and they raced toward the shrine, trampling Tikal.

"Stop it!"

The seven Chaos Emeralds appeared around the Master Emeralds as the echidnas reached the top of the shrine. Chaos emerged from the Master Emerald.

"What is this thing?!" he said.

Chaos raised its hands, and the Master Emerald started to glow brightly. The echidnas were forced to shield their eyes. The Master Emerald glowed intensely, and suddenly there was a white glow that enveloped everything. When it died down, the Master Emerald's glow died down, and the shrine was on fire.

"They're gone. All of them." Knuckles said.

"Not all." Sonic said and rushed over to an unconscious Tikal. "Are you okay?" he asked as Tikal slowly sat up.

Opening her eyes, she saw the burning shrine.

"I knew this would end in disaster. Why, Father, why didn't you listen to me?" she said and got up and dashed toward the shrine.

"Hey, hold on!" Sonic said and they followed her to the top of the shrine, where she started to pray.

"You must understand. The servers are the seven chaos. Our hearts intensify their power. The controller serves to unify the chaos. The seven Chaos Emeralds take what is in our hearts and turn it into power. Hmph... But if the heart that wields the Emeralds is full of nothing but angry and fear... then that power will being pain and destruction to the world. Oh, please, you must stop Chaos!" she said and spread forth her arms as the Master Emerald glows, ending the vision bringing them back to Mystic Ruins.

"She's gone." Knuckles said.

"Knuckles, did you understand what she meant about Chaos?" Sonic asked.

"We have to stop Chaos from getting hold of the last Emerald.

"Hey, you guys! Look!" someone said.

Knuckles panicked when he saw Chris approaching him, white Chaos Emerald in hand. Suddenly, the ground directly underneath Chris rumbled, and a huge geyser of water launched into the air.

"Chris!" Sonic said then leapt into the geyser and took his hand. "Hold tight, buddy!"

With his energy sapped, Chris let go of the Chaos Emerald.

"Just hang on!" Knuckles said then leapt into the air, and karate-kicked the geyser, releasing Sonic and Chris.

Sonic landed on the ground, still carrying Chris. The ground started to crack, swallowing the Chaos Emeralds and Knuckles' bag of Master Emerald sharded. Tails flew out of the way just in time as a massive geyser of water burst out of the ground, then fell back in.

"So Chaos has all seven Emeralds now." Knuckles said.

"I'm sorry, Knuckles. It's all my fault." Chris said.

"That creature is more powerful than all of us. It can't be stopped."

"But we have to try." Sonic said.

'If I have to I'll use my guitar.' he thought with a hand on his medallion.

Nearby, a few sad Chao floated down.

Meanwhile dark clouds gathered above Station Square. Everyone stopped as the ground started to rumble. Water rushed through the sewers.

Sam was giving someone a speeding ticket.

"You were doing fifty in a 35 mph zone. But since you did ask me for my autograph, I'll let you off the warning this time." he said.

Suddenly the nearby manhole exploded into the air as water gushed out like a geyser.

"Whoa! Must be a water main break!" he said.

But that wasn't the only incident. Across the entire city, manholes were launched into the air by the sheer force of water, sending people screaming and running.

"Let's get out of here!" people said.

"Weird."

Then a giant crack formed in one of the streets, and water gushed out of it. It even burst out of the tops of skyscrapers. People fled into one of the buildings.

"You'll be safe here! Hurry!" Sam said.

Suddenly a wave swept him away. One of the waves of water exploded out of one of the buildings and formed into a giant head. The creature's eyes opened, and it roared. Perfect Chaos was born.

At the White House the President, Christina, Topaz, and Rouge were watching Scarlet on TV reporting the breaking story from a helicopter.

"Station Square is flooded! We don't know the exact cause of the disaster yet, but eyewitnesses reported that something went horribly wrong in the city's water system. As you can see, there's complete devastati- Oh my.. There's something down there..." she said then saw Perfect Chaos moving through the city and started to panic. "It's appears to be some kind of monster!"

At the SSTV Newsroom. "Tell that pilot to fly closer to the monster!" the Technician said.

At the White Houe the President and Christina took frantic calls from officials as Topaz and Rouge stood by.

Rouge was starting to wonder if Sonic will be able to fight this one.

"Counter attack is impossible!" Caller 1 said.

"Our missile launcher was caught in the flooding." Caller 2 said.

"What about fighter jets? How many do we have in the area?" Christina asked.

"Throw everything we got at it. As commanding chief, I authorize you to do whatever it takes stop that thing." the president said.

In Station Square Perfect Chaos slashed a building in half with one of its tentacles.

Meanwhile Ella, Cream, and Cheese were in the living room watching the breaking story.

"Much of the city is now in ruins! The only good news is that nobody has been seriously hurt. But the monster is still attacking us!" Scarlet said.

Suddenly Cheese started freaking out.

"What are you trying to say, Cheese, huh?" she asked.

"Don't worry, that blob would hurt you." Ella said.

"Right, we're going up to the mountains where it's safe." she said but Cheese refused to calm down. Chuck entered.

"What are you waiting for? We have to get out of here fast!" he said.

"But we can't go yet because Mister Chris still hasn't come back home." Ella said.

"Where is he?!"

Meanwhile at the X-Tornado.

"We've gotta stop Chaos somehow. Faster! We don't have much time." Chris said.

"Better hang on!" Tails said.

Below them, Sonic was running toward the city.

"If I don't get to the city fast, there won't be anything left to save." he said.

At Station Square the digital billboard showed Perfect Chaos's rampage.

"The monster is downtown, leaving a wave of destruction in its wake!" Scarlet said then Perfect Chaos destroyed the billboard.

Perfect Chaos destroyed the billboard.

At Chris' school the students were being evacuated.

"Children, we're all moving up the slope there." Mr. Stewart said. "Roger, this is Chalkboard Charlie." he said on his communicator.

"We need you back here at headquarters on the double!" and agent said over the wrist communicator.

Mr. Stewart saw Danny and Frances struggling with Helen's wheelchair.

"But I can't leave my students!" he said.

"What?! This is a direct order!"

Mr. Stewart gritted his teeth in frustration, then sighed.

"I'm sorry, I didn't copy that. Can you repeat, Homeroom?"

"Sir?" Frances said.

"Are you the last ones?"

"Yeah, the others went ahead." Danny said.

"That's good. Then follow me!"

"Okay." Danny and Frances said.

Mr. Stewart grabbed Helen's chair and ran with Danny and Frances following.

At Thorndyke Mansion Entry Chuck, Ella, and Cream were ready to leave.

"I'll wait for Chris. As a former water polo champion, I can swim both of us to safety when the flood comes." Tanaka said.

Chuck picked up Cheese, who was still upset, though not as much as before.

"Alright." he said.

Cream opens the door as she, Ella, and Chuck leave the mansion. Tanaka stays to wait for Chris.

At Station Square several people pulled Sam to safety. Among them was Jerome.

"Thanks. That was close." Sam said. "Alright! Hope they send that thing down the drain!"

"Commence attack pattern bravo." Pilot 1 said.

"Copy that, Squad Leader." Pilot 2 said.

"Let's take it down!" Pilot 3 said.

The choppers open fire on Perfect Chaos, but no damage is done.

"Switch to missile fire now." a Pilot said.

Missiles were launched at Perfect Chaos, which absorbed them and breathed them back at the choppers.

"No way!"

Then Sonic arrived in town. Seeing the carnage then a picture of Mobotropolis before beating Robotnik, he gritted his teeth and sped off into the wrecked city. Meanwhile, the helicopters were destroyed by their own missiles. The citizens watch helplessly.

"Oh my gosh! The islands are okay! We need Sonic." people said.

Eggman, Decoe, and Bocoe were sitting in a giant cockpit of some sort. The lights slowly turn on.

"Systems are go." Bocoe said.

"Let's take off!" Eggman said and a large door opened, and the giant cruiser they were sitting in started to rise. "A successful evil genius always have a Plan B. That's why I have the Egg Carrier 2. Chaos better watch out. Things are about to get really chaotic. Hahaha!"

Back at Station Square Sonic watched Perfect Chaos' relentless rampage.

"That's it, Chaos! Your destroying days are over!" Sonic said and took a mighty leap into the air and spun toward Perfect Chaos' head.

"Hey, look!" someone said.

But the water god used a tentacle to slam him back to earth. Sonic then ran up one of the few skyscrapers standing and flew toward Perfect Chaos. However, he absorbed him, spit him out, and reared up a mighty wave of water to catch him. Sonic was lucky enough to land a floating board of wood, and rode it like a surfboard.

"Sonic!" someone said so he looked up to see the X-Tornado approaching him.

So he took hold of Chris' outstretched hand.

"You all right?" Chris asked.

"Yeah. Thanks, Chris." Sonic said.

"You think.. we'll win?"

"It'll turn out okay. But Chaos is more powerful then ever, so I'll need plenty of help. Can I count on ya?"

"You bet."

"Okay, then. Let's do it!"

Tails flew the X-Tornado into battle avoiding several water spears before buzzing Perfect Chaos. Suddenly, they were overshadowed by the Egg Carrier 2.

"What's this?" Sonic said.

"Back off, Sonic! Chaos double-crossed me. Now it's payback time!" Eggman said.

"Eggman! This time he's fighting on our side?"

The n the Egg Carrier 2 closed in on Perfect Chaos.

On the Egg Carrier 2. "All attack systems are online." Decoe said.

"Blast charges are loaded and ready to fire on your command." Bocoe said.

"You're through, Chaos! The price of disloyalty to the Eggman Empire is annihilation. Front missiles, fire." Eggman said.

Back at Station Square the Egg Carrier 2 fired many missiles at Perfect Chaos, but they were quickly deflected by a force field. Then he fired a giant laser from its mouth, destroying the Egg Carrier 2 and they escaped in the Eggmobile.

Sonic saw this.

"Oh, great! How are we gonna beat it now?" he said.

"You have to try your medallion for this." Knuckles said from nowhere.

"Huh?" people said while Sonic bit his lip knowing he was right.

"You've done this plenty of times in the past and said it was time to keep it on for emergencies. And this is an emergency!"

Sonic knew he was right so he nodded then looked at Chaos, took a deep breath then tapped his medallion and everyone gasped.

Then for the first time in four years got ready for a real fight.

"Let's hope I still got it." he said then raised his guitar and hit it at Chaos causing everyone to gasp again and get it hard but only went through it.

'Oh crud!' he thought and did again and again.

"It's not working!" he said. "It's not gonna work so we need to try and figure something else out."

So he put it away. Then, a bright light moved in, blinding the X-Tornado's occupants. The light surrounded the X-Tornado and safely guided it to a landing position on a bridge. Sonic leapt down from the X-Tornado.

"This just keeps getting freakier and freakier..." Sonic said then a female echidna appeared. "You again!" he said and the light faded.

"Since the day of my father's invasion, I've journeyed across the seas of eternal time with Chaos to help keep its power under control. But some friend woke Chaos for a plan to use its power for an evil purpose." Tikal said.

"Eggman... He must have uncovered the way to revive Chaos somehow so he could use it to take over the world."

Then she saw Eggman and Chaos. Perfect Chaos spit out the Chaos Emeralds. The purple Emerald landed in front of her. It was petrified. Tikal picked it up.

"Chaos has now drained all the Emeralds of their power."

"What?"

"Ever since my clan attacked the temple, Chaos has known only hate and anger. He will use the power of the seven Emeralds to destroy this world. We have to seal Chaos back in the Master Emerald before it's too late!"

"It won't work." she said and she stood up. "If we seal it in the Master Emerald, the same thing will only happen again. We have to solve this problem once and for all."

"Yes... but how can we?"

Sonic didn't know how to answer.

"Sonic! Sonic!" someone said and saw Cream carrying a petrified yellow Chaos Emerald. "Look, I have something for you!" she said and Ella, Tanaka, and Chuck also arrived.

"Cream got the Emerald back after Chaos let them all go." Chuck said.

Amy also ran in carrying a petrified blue Emerald.

"Hey, Sonic!" she said.

Then Big arrived holding up the green Emerald.

"I finally got back the pretty rock that Froggy swallowed. You can borrow it if you want to." he said.

"Sonic! If you collect all the Emeralds, you can defeat Chaos!" Tails said.

Then Knuckles held out the red Emerald.

"Here. You have more experience at being a hero." he said. "I uh, actually forgot I had it. Sorry."

"Thanks, Knuckles." Sonic said. "It was worth a try. I don't know what to do about my medallion after this though."

"Use it. Don't tell them who you are or something but tell them what it can do and where it came from." Sonic sighed but nodded.

Then Knuckles turned to Eggman, knowing he hiding an Emerald.

"Bu-Eggman." he said.

"Oh, all right. Take it." Eggman said and handed over the petrified cyan Emerald.

"We need one more." Tails said.

"Sonic! Look what I found!" someone said.

Chris was coming with the last Emerald: the white one. However, he tripped and fell on his face so Sonic ran over with the big brother from him.

"Chris!" he said and Chris looked up.

"Sonic, look!" he said and held up the Emerald.

"I knew you'd come through."

The crowds cheered for Sonic from the wrecked buildings.

"Go, Sonic! Yeah, Sonic! All right!" the crowd said.

Then the Chaos Emeralds' power started returning.

"The Emeralds are getting their power back!" Chris said.

The Chaos Emeralds started levitating. And then started to orbit Sonic. He closed his eyes and let them change him into Super Sonic. His quills stood up, and he rose into the air.

"I thought that the power of the Chaos Emeralds could only be awakened by hate and anger." Tikal said.

"There are other feelings that are even more powerful." Knuckles said. "And like I am for the Master Emerald, Sonic is the Guardian of the seven Chaos Emeralds.

"When everybody gave their Chaos Emeralds to Sonic, it was because of our friendship. Caring is stronger than hate, and that's how Sonic is gonna beat Chaos." Tails said.

Sonic finished changing into Super Sonic, then turned to Perfect Chaos, who prepared itself for battle. Then he projected a barrier around itself, but it was smashed by Super Sonic. Perfect Chaos then turned its tentacles into drills, but Sonic spun into them, shattering them. Not even Perfect Chaos' laser mouth hurt Super Sonic, so it fired an even stronger laser that headed toward Chris and the others. Super Sonic moved in front of it.

"Aaahhh! ... Sonic!" Chris said but the beam did nothing.

"You can't stop me!" Super Sonic said and the others smiled.

Mr. Stewart and his class cheered Sonic on from a hill far away from the city.

"If anybody can stop that monster, Sonic can." Helen said.

"Go, Sonic!" Danny said.

The kids cheer with chants of "Go, Sonic!" Perfect Chaos whips a tentacle toward Sonic, but he uses a hand to stop it, and then uses Chaos energy to dissolve it.

"Is that the best you can do?" Sonic asked.

Then Perfect Chaos fired a laser beam from its mouth again, but Super Sonic charged headfirst toward it, and forced it back to sender. Once he flew inside he left again as the water god glowed gold and vanished in a bright light. The crowds cheered. Super Sonic had won. Then, the puddle that was Chaos landed on the ground, and reverted to its base form.

"It wasn't destroyed. It survived!" Knuckles said.

"Chao chao chao." Cheese said.

Many other Chao rose from the water and surrounded Chaos, including Cheese. Then they beamed.

"But it doesn't look angry anymore." Knuckles said.

"Yeah. If you ask me, Chaos actually looks kinda happy." Tails said.

"Wow, look at all those Chao!" Cream said.

"I wonder where they came from?" Chris asked.

"It looks to me like those Chao were friends of Chaos who came here to see him." Amy said and Tikal stepped in front of Chaos.

"These are the Chao you kept watch over." she said and Chaos looked around at the Chao.

There was a flashback of Chris, his friends, and the Chao.

"They are coming into this world now. The Chao will live here in peace, and you can be at peace now too." she said and the flashback ended. "Time to go." she said and spread forth her hands, and she and Chaos rose into the air.

Sonic was now back to plain Sonic and looked at the city in concern. Then Tails broke the silence.

"Huh? Where'd Eggman go?" he said.

"I think he escaped while we were distracted." Tanaka said.

"Yeah, well, he won't get away next time." Knuckles said as Chris approached Chris.

"You did it, Sonic!" Chris said and Sonic turned around.

"We all did." he said and gave him a thumbs with and Chris returned the thumbs up.

"I have one question." Tails said.

"What is it?" Sonic asked a little nervous.

"What happened with your medallion?"

"Yeah, what happened?" someone asked.

Sonic looked at Knuckles who stood next to him for support and then took a deep breath.

"This isn't the first time you've seen this. You, Amy, Cream, Cheese, Chris and Eggman had seen this but I had someone erase your memory for this. This medallion is a weapon me, my sister and brother have. Me and my sister's are lasers and my brother's is an earthquake I guess you could say. But work as a guitar, drum and keyboard to. We used to play them a lot."

Knuckles snickered.

"No kidding. You three talked me into leaving Angel Island to help you with it!" he said.

"Hey, you gave in and probably for Sonia to." Sonic said ending smirking.

Knuckles turned red.

"If I wasn't your friend Chomps would be having you for dinner tonight." he said.

"Chomps?" Topaz said.

"His/my pet dinosaur." Sonic and Knuckles said.

Everyone looked at him in shock.

"What? He's friendly if he likes you and gets along with Sonic, Sonia and Manic just fine." Knuckles said and shrugged.

They were still shocked.

"Anyway, we don't know exactly what it can do but it was our weapon before I left. Then I only had my medallion, speed and tricks. When I left I started using the seven Chaos Emeralds."

While he explained what exactly they can do it shocked them all.

"So there you go. Now you know why I have this medallion on full time like I used to."

They nodded and Knuckles looked at him.

"Play it as a plain guitar and show them what you can do." he said smiling.

"What?"

"Come on. I haven't heard you sing in five years!"

Sonic looked at them all and sighed.

"Fine." he said and tapped it and thought. "Hmmm, I got it!" he said and got ready.

"No one, no one is an island

No one, no one stands alone

No one, no one is an island

No one, no one's on their own

Sooner or later you will understand

When you help others you are helping yourself

You've got to learn to lend a helping hand Learn to take help when it comes from someone else

Whoa... 'cause

No one, no one is an island No one

No one, no one stands alone

Nobody stands alone

No one, no one is an island

No one is an island

No one, no one's on their own

Nobody's on their own

No one, no one is an island No one, no one stands alone" he sang and Knuckles groaned and covered his face.

"Did you have to play that?" he said when people came back and cheered.

"That was awesome!" they heard people.

"Hey, you had me sing." Sonic said smirking.

"Huh?" they all said.

"It's a long story. They played a few when I was with them." Knuckles said.

Suddenly someone appeared causing them all to jump.

"Sonic. Knuckles." Oracle said.

"Oracle? What are you doing here?" Sonic asked.

"To tell you I will not erase the memory this time. They have a right to know what you can do with it. Use it from time to time like you once did."

They stood there in silence.

"Do it." Knuckles said.

"You know what it can do and said you keep it on as an emergency now so use it."

Sonic sighed and nodded.

Then he got close to Oracle.

"But I'm not telling them what I am." Oracle nodded. "For now."

Sonic groaned.

Then Oracle was gone and Sonic shook his head.

"I really hope I don't have to use it again or expose what I really am." he muttered to Knuckles.

"I don't think you will." Knuckles muttered.

Seeing them talk to each other hurt Tails.

Sonic had hid a lot from him and things that Knuckles knows to go with it.

'Do I really know them?' he thought.

"OK, now that that's done I'm headed home to relax and clear my head. Tell Chomps I said hello when you get back to Angel Island." Sonic said and left.

Knuckles was a little worried about him now knowing he was getting close to everyone finding out what and who he really is.
