Flashes of light zoomed across the sky. Then disappeared.

Among strange wreckage, two hedgehogs panted from the heavy-duty fight that they just had. Sonic grunted and held his arm in pain, and Silver quickly helped his partner. "He's tougher than we thought!" Sonic thought to himself. "Silver and I better finish this!"

The two hedgehogs stared at the newest villain. It held up his sword. With just one swipe, the two hedgehogs were sent flying away.

"Your defeat is certain." The monster huffed. "Give me the Chaos Emeralds and I will spare your life,"

Sonic and Silver looked at each other and nodded. The two raised their golden arms as the emeralds came up to their call. "CHAOS CONTROL!" They yelled in unison.

All seven emeralds glowed in response, and they flew off in different directions to different planets.

The Metarex turned to face the tough hedgehogs. They just smirked, but lost all senses and fell to the ground, unconscious

The Metarex looked down at his injured side, the place where Sonic and Silver had attacked.

"Sonic and Silver have only delayed my triumph!" The Metarex growled in annoyance. "Those emeralds will be mine!" He looked over at the planet where Sonic and Silver had fallen to. "Alert my forces across the galaxy. Begin the search for the Chaos Emeralds at once. Do not rest until you bring them all to me!"

Soon, he was joined by more Metarex. "Bring the Egg Planet to me." He ordered.

...

"How much longer do we have to wait, Tails?" The little bunny asked, excitement in her voice.

"I'm itching with excitement here!" Penny squealed.

"I'm not exactly sure, Cream. And don't worry, Penny. It won't be too long." Tails said, adjusting his camera.

"This would be so romantic if Sonic were here to see it with me!" Amy smiled happily to herself, clasping her hands together in excitement at the thought of sharing a meteor shower with Sonic. Beside her, a lemur with a long tail rolled her eyes. "Yeah, I'm sure he'll be happy." She said.

Penny only frowned at Amy.

"Say all you want, Tangle, but I think that would be super romantic!" Amy smiled, waving off the lemur. Tangle switched her long tail anxiously. "Soon the whole sky will be filled with shooting stars!"

"According to the astronomers, we only get a meteor shower this humongous once every five hundred years or so!"

"Wow!" Tangle said, clearly impressed. "Then we're really lucky to be here!"

"I sure wouldn't want me to wait that long to see it again! Won't you?" Cream asked.

"We should all make a wish!" Amy smiled.

"Why should we do that?" Tangle asked. Blaze smiled. "Penny, Kat, and Chris told us if we wish upon a shooting star, it'll come true!"

"Remember Tails?" Cream asked. Tails sighed. "Yeah." He said. "It's too bad Kat, Chris, and Chuck aren't here to see this with us."

"I miss them." Cream said.

"Hiro has been awful lonely since he left Kat behind on Earth." Blaze said. "I wonder how they're doing now..."

"I wish we can go back to your world for a visit!" Cream told Penny with a smile. Penny grinned back.

"You seem to love these Kat and Chris characters." Tangle smiled at the group.

"Well, Kat and Chris were close friends to us..." Tails smiled, looking down.

"And Chris was my little brother. And Kat is my BEST friend. The two people I had to leave behind." Penny said sadly, looking down. Cream gave the now fourteen-year-old girl a hug. Tangle even looked sorry for her.

"I wish Whisper was here." Tangle said, looking around for the female wolf. "I wonder if she'd found Silver yet... She must be worried about him..."

"He'll be fine." Blaze smiled. "After all, Silver and Sonic have handled themselves quite a bunch of times..." Tangle looked up and gasped in excitement. "It's starting!"

"It's beautiful!" Cream cried.

"I never saw a meteor shower like this back at home!" Penny exclaimed excitedly.

"I'm sure glad we got a camera!" Tails smiled.

The meteor shower was soon growing, and a meteor flew right towards them.

"That's a huge looking meteor!" Amy said, eyes wide.

"So bright!" Penny gasped.

"If I didn't know any better, I'd say that it's headed straight towards us!" Cream pointed out.

"Hey, she's right!" Tails said, his eyes wide.

"GET DOWN!" Tangle yelled, and she used her long tail to keep her friends safe from danger. They yelped in shock. After a moment, an explosion was heard. The gang ran as fast as they could towards the scene.

"That's no shooting star!" Blaze said, her golden eyes widening with surprise.

It was a ship. And there was a person... a young girl... lying next to it, unconscious. It seemed like she got knocked out when the ship crashed.

"Oh, no!" Penny gasped, covering her mouth in shock.

Tails was the first to run over to her, with Penny close behind. He picked the girl in his arms. She groaned in pain.

"She needs help." Tails mumbled, not taking his eyes off her.

"Your house is the closest one around here, Cream," Amy said to the young girl. "I think we should take her there."

"I'll go tell Mother you're coming!" Cream said, and using her long strong ears, she flew away, and Cheese followed her.

Tails stared at her in shock and bewilderment. "I wonder who she is. And where she came from..." He thought. He looked up at the stars and wondered.

...

Sonic and Silver laid down next to each other, exhausted. When they opened their eyes, they darted awake when they realized where they were. They looked around to see Dr. Eggman.

"Eggman!" Sonic spoke first. "What happened?!"

"I've been sitting here for the better part of the week waiting for you two to wake up and tell me!" Eggman growled. "I was out jogging to maintain my perfect physique when I spotted something. You two were in pretty bad shapes, Sonic, and Silver." Eggman said. "You were battered like a fish stick! It was a tough decision. I didn't know whether to save you or wait for the tide to come in!" Eggman hooted with laughter.

"You were in terrible shapes, Sonic and Silver!" Bocoe pointed out. "Dr. Eggman saved your life!"

"If he hadn't, he wouldn't have anybody to pick on!" Decoe said, sheepishly rubbing the back of his head.

"What happened to have you get passed out on the beach anyway?" Bokkun asked curiously, handing Sonic and Silver a drink.

"I don't know," Sonic said. "Silver and I were fighting somebody." He sat up a little too quickly and bumped into Bokkun, who spilled the drink all over himself. "Hey, sorry." Sonic chuckled nervously. Silver grabbed Sonic's arm. "But we can't say anymore!"

The two darted off.

"You're leaving?" Eggman asked curiously.

Sonic and Silver smirked at each other. "See you later, Eggman!" They said, and they dashed out together.

"HEY!" Decoe yelled. "You owe us, Sonic and Silver!"

"You two may run fast, but when it comes to paying your debts you sure are a slowpoke!" Bocoe growled.

"YEAH!" Decoe cried.

"That is the last time we help you!"

Watching the whole thing once again from an air vent, Rouge smirked to herself. "Ah..." She smiled.

...

At Cream's house, the whole sky was still full of shooting stars. The young girl they found was shuddering in her sleep. She was having a nightmare... no, more of recalling a memory of what happened.

She was running as fast as she could as the whole building looked like it was about to collapse on her. An explosion shook right in front of her, causing the girl to fall down. Shuddering, the girl looked in the smoke to see a monster. Its gleaming eyes shown at her, and she heard her family yelling. "COSMO! RUN AWAY!"

Cosmo yelped as she opened her eyes.

"She's waking up!" Vanilla whispered.

Cosmo groaned as she gained her senses. She looked around her to find worried faces all around her. She groaned as she tried to sit up. "Careful, dear, don't try to sit up," Vanilla warned gently.

Cosmo smiled a little at them.

"Are you okay?" The strange girl with reddish-brown hair and bright blue eyes asked worriedly.

"You were in a big crash." The pink girl said. "You're really lucky that you didn't have any serious injuries."

The bunny looked at her. "Maybe you can tell us where you and your ship came from!"

"I..." Cosmo began, but she placed her hands on her mouth.

"I can't." She whispered. Penny's eyes widened and she placed a hand on Cosmo's shoulder.

"You mean... you can't remember?" Cream asked.

"I can, but I... I can't tell you," Cosmo whispered, clutching the blanket.

"Why?" Tails asked.

Cosmo looked up at him. "I'm looking for someone on this planet named Sonic the Hedgehog. It's very important, that I speak with him as soon as possible. Before it's too late!"

"You can talk to us." Tangle said softly to the girl, though her tail was twitching with excitement behind her. "We'll help you if we can."

"What's the matter?" Tails asked the girl.

"I can't tell you." Cosmo whispered.

Amy was getting furious. "Well, have the right to know!" She snapped.

"Amy!" Penny snapped.

Amy continued, ignoring Penny. "Sonic's my boyfriend, and you better not try to move in on him!"

"He's not your boyfriend, cotton candy!" Penny snapped, but luckily Tangle and Blaze held her back.

"Amy, she didn't come here to date him! Please leave Penny alone!" Cream cried, holding Amy back as well.

Cosmo just looked confused.

"We're friends of Sonic, so maybe we can help!" Penny smiled, turning back to her.

"Friends?" Cosmo whispered.

"My name's Myles Prower!" Tails smiled. "But everybody calls me by my nickname, Tails!"

"And I'm Cream, we're very happy to meet you!"

"I'm Blaze." The purple cat said, smiling at her.

"I'm Tangle!" Tangle said cheekily with excitement, shaking the girl's hand. "And this is my best friend, Penny! She's also new here."

"Hi!" Penny smiled warmly at Cosmo. Cosmo smiled back at Penny... she had a feeling that she and Penny were going to be great friends.

"And my name's Amy Rose!" Amy shot at the girl. "You're not going to be here long, are you?"

Penny glared at Amy.

Cosmo moaned a tiny bit, her gaze going back to the blanket.

That's when a noise startled them. Penny ran to the window first, and immediately wished that she didn't. She quickly looked away, looking sick, along with panic on her face.

"Penny?" Tails asked with worry. "What did you see?" He, Blaze, Tangle, Cream, and Amy hurried over to the window, and their eyes widened as they saw a strange robot sailing downwards.

"What's that?" Cream asked.

"It's something big!" Tails said.

"Like robot big!" Tangle said with excitement. "I was wondering when a little adventure would come in!"

"You should stay in bed." Vanilla's worried voice suddenly broke the tension. Penny and the others turned to see Cosmo staggering towards the window where Penny had spotted the new danger. Cosmo stopped short, and Penny saw real fear in the newcomer's eyes.

"It's another Metarex." Cosmo whispered in fear.

...

While all of this was happening, Knuckles had been sleeping near the Master Emerald when a strange sense caused him to wake up. Knuckles sat up, and his gaze turned to shock when he saw the new monstrous robot slowly and menacingly moving down towards Earth. He watched as the monster lowered itself into the forest, and then an explosion from where the monster landed was followed soon after.

"This looks like... trouble." The echidna said, sweat dropping a little at the sight.

"Preparing Planet Egg removal." The monster said. It shot lasers from the top of its helmet, and soon the forest caught on fire.

Knuckles growled at the sight of it. "If that thing isn't stopped, it's gonna burn up every tree in the forest!" He cried. He hopped down and ran towards the monster. "HEY!" He yelled, getting the creep's attention. "Knock it off, you fire butt!" At that, Knuckles raised his leg and readied his fist, and tried to punch it, but to his shock, the punch didn't even leave a dent! Knuckles gave a yell as the monster tossed him away into the forest.

Luckily, thanks to Knuckles's training, the echidna landed swiftly on his two feet. After he landed, missiles started shooting at the monster.

"KNUCKLES!" Tails hollered from the X Tornado.

"All right!" Knuckles growled. "Maybe we can stop him together!"

"This doesn't look good..." Tails gulped.

Cosmo could only watch.

"Looks like our only choice is to keep pounding away!" Knuckles growled, dashing at the beast again.

"We're going on the attack! Are you ready?" Tails asked Cosmo.

Cosmo nodded. "Yes." She answered.

And at that, Tails fired.

...

"The whole forest is on fire!" Cream whimpered, and Blaze put a comforting hand on the girl's shoulder.

"Oh, no!" Penny cried.

"This can't be a coincidence..." Amy mumbled as she watched the destruction. She looked up at the X Tornado, where Tails, Tangle, and Penny, especially Cosmo, were in. "I bet that girl knows why this is happening." She said. "I wish there was a way to convince her to talk to us."

"Yeah..." Tangle said.

...

"Our lasers have no affect!" Tails said with worry.

"You need to use much stronger attacks if you're ever going to beat a Metarex." Cosmo explained, her face lined with worry.

Tails looked curious about this. "Do you know why it came here? Or why it's destroying all the trees?"

Cosmo looked up, her face full of fear. "Its mission is to find the life force of this planet and steal it away."

"That's not good." Tails said.

"It's not." Cosmo said in agreement. Tails was about to ask Cosmo more questions when two familiar spinning balls darted past them. With a furious punch, the two knocked the Metarex down.

"He's back!" Tails gasped.

Cosmo gasped, her eyes wide, and she stood up, and then groaned. She bumped her head on the ceiling. Tails looked at Cosmo with worry. "Are you okay?" Tails asked.

"Yes." Cosmo said. She held her head and looked down at Sonic and Silver. "So that's Sonic and Silver. Our final hopes."

...

Sonic and Silver watched as the Metarex stood up.

"You're the one who's going down in flames now!" Sonic growled threateningly.

"That's right!" Silver said. "No one threatens the forest!"

...

In Chris's world...

Eighteen-year-old Christopher Thorndyke smiled to himself as he typed furiously on his computer. Just a few more tweaks and it was finished.

"Here's a sandwich, Chris," Katrina said with a smile, as she set the plate down in front of him.

"Thanks, Kat," Chris said with a smile, biting into his lunch.

"Is it almost done?" Kat asked, excitement in her voice.

"I think so, there's still one more thing I need to figure out," Chris said, turning back to his laptop.

What was he building? He was building a portal, just like the one Sonic, Penny, and the others used to travel back to Sonic's world. After a few minutes, an idea popped into Chris's head.

"Hey, I know." The teen said. "Maybe if I increase the energy in the transport circuits..."

He typed a little bit more on the computer, and his screen lit up in the color of red. "That's it!" Chris exclaimed. "All right! Kat, it's finally time to try this out!"

"Have you figured it out?" Kat asked.

"Yes." Chris said with a nod. "Let's go." He walked up to the machine. "My machine is like the one Grandpa and Tails built to send Sonic and the others back home. But it doesn't need Chaos Emeralds. If it works, we'll finally be able to see Sonic and Penny again."

"And Hiro, Cloud, Silver, Blaze, and the others!" Kat smiled.

Chris smiled back, and his gaze drifted over to a photograph of himself, Penny, Sonic, Tails, Cloud, Blaze, Amy, Kat, and Hiro. Man, he missed the old times. Most importantly, he missed his older sister. She would be nineteen now if she was still here.

The wind rustled, and the picture fell off the sill. Chris and Kat started at the sudden fall and dashed over to pick up the picture.

It was at that moment that the two friends knew something was wrong. Chris tenderly touched the image of Sonic and Penny. "We're coming..." He mumbled.

...

"Head's up, Sonic and Silver!" Tails called from the plane, shooting out a ring to the two hedgehogs.

"Thanks, Tails!" Sonic and Silver called, and they spun at the Metarex. However, the Metarex started throwing ropes at Sonic and Silver, but the two hedgehogs easily dodged them.

Knuckles growled as he dodged at them, but yelled as the claw pushed him away, and grunted as he landed besides Sonic. "It's...pretty tough!" Knuckles huffed.

Sonic sweatdropped, and looked up at the monster. "Yeah." He said in agreement. "But we can beat him, buddy!"

"Gotta plan?" Knuckles asked.

Sonic and Silver did an anime sweatdrop.

"Triple Team," Sonic said. Silver nodded, and they took off. "Let's go!"

...

"I thought Sonic would move much more quickly than he normally does." Cosmo said as she studied Sonic from the X Tornado.

"Something's not right." Tails said. "Sonic and Silver aren't moving as fast as they normally do." He tried firing at the Metarex again, but no avail.

"This is impossible!" The fox said, sweat dropping. "No matter how hard we hit that thing, it keeps going!"

...

"You'll have to use the Chaos Emeralds to stop this thing!" Knuckles said, turning to the blue and silver hedgehogs. "I'll distract it with a frontal attack so you two could move in and finish it off."

Silver looked even more nervous.

"We'd like to," Sonic said with a shrug. "But I don't happen to have the Chaos Emeralds with me now."

Knuckles turned to him, stunned. "Wh-where are they?"

"Well, Silver and I kinda got into this fight out in space, and the bad guy was going to take them from us, so I sent them away!"

Knuckles looked shocked. "You finally had all seven Chaos Emeralds together... and you threw them away?!"

Sonic shrugged. "Exactly!" and Silver nodded.

Furious, Knuckles grabbed Sonic and started shaking him. "ARE YOU CRAZY?!" He screamed at the two hedgehogs. "WHAT ARE WE GONNA DO?!"

"I guess we're gonna have to find them again!" Silver said.

Their conversation was interrupted when one of the Metarex's claws smashed into them, causing them to fly away. Tangle, Penny, Amy, Blaze, and Cream ducked as a claw headed their way, but was soon destroyed by a familiar wispion.

"Whisper!" Blaze, Tangle, Penny, Amy, and Cream cried.

Whisper said nothing, but placed her mask over her head, and was about to attack it with her wispions when a blue light zoomed out of the center of the planet.

"Proceeding with planet egg removal!" The monster drowned.

"Oh, no!" Cosmo cried as she watched the whole scene.

"What is it?!" Penny gasped. The sudden light grew too bright for eyes, and she covered them. When she opened them again, the human girl was stunned to find a giant hole in the ground. A second later, a galaxy like object from the ground appeared, and was encased in a jewel-shaped safe.

"What in the world is that?!" Knuckles gasped.

Up in the air...

"He's found the Planet Egg..." Cosmo whispered.

"What's the Planet Egg?" Tails asked.

"It's the lifeforce that sustains your world," Cosmo explained.

Penny, Tangle, Amy, Cream, Cheese, and Whisper gasped.

The forest had started losing its color.

"The Planet Egg is what gives your world the power to support life." Cosmo continued. "Without it, every living thing here will soon perish."

Everyone gasped at the shocking change of the forest.

"Procedure complete." The monster announced. It lifted off the ground, with the Planet Egg in its hands.

"Hold it!" Sonic and Silver yelled, and was about to destroy it with one blow, but was soon knocked down.

"I gotcha!" Knuckles growled and caught Sonic and Silver as they fell. Whisper, Tangle, Penny, Amy, Blaze, Cream, and Cheese ran up to them.

...

"I'll stop that thing!" Tails growled. However, the Metarex disappeared into the sky before the fox could attack. "I can't go any higher because this plane wasn't designed to travel into space!"

Hearing Cosmo groaning, Tails looked at her. "Are you alright, Cosmo?"

"I'm just... a little... dizzy." The girl whimpered, shaking her head.

"I'm sorry." Tails said apologetically. "I just wish I got the planet egg back."

Tails watched curiously as Cosmo touched the roof of the plane. "Could you... open this for a moment, please?" She asked.

"Hu?" Tails asked.

"You can open it, can you?" Cosmo asked.

"Yeah, but I'm not sure I could do it in this altitude,"

"Please, Tails," Cosmo said.

"Okay, if you really want me to." Tails said, opening the window.

"There you go..." Tails gasped as Cosmo jumped out of the plane, using her dress as a parachute.

...

"Sonic, are you sure you're doing okay?" Penny asked with worry as she looked at her best friend. Sonic shot her a thumbs up. "Of course I'm okay!" He said.

"You didn't put much of a fight against that thing, Sonic. Neither did you, Silver." Knuckles said in agreement, looking at them with worry.

"You don't sound like yourself," Amy said.

"It's been a long day," Sonic said. "So I guess I'm a little tired." He looked up, and Penny followed his gaze. To her surprise, she saw Cosmo floating down towards them. When she landed, the girl straightened out her dress and smiled at Sonic. "My name is Cosmo." She said. "I've come a long way to see you. I need to speak with you, Sonic and Silver."

Both hedgehogs looked curious. "Okay..."

Cosmo clasped her hands. "I have sought you out because I know you two have the power to control the Chaos Emeralds. I have come here because you are the ones who can rescue the galaxy!" She said, bowing respectfully.

"I am?!" Sonic asked.

This would've continued more if Tails hadn't ran up to the small group. The little fox had been running for a while. "GUYS! IT'S HAPPENING!" The fox yelled.

"What's happening?!" Knuckles yelled.

...

"Dear Mom, and Dad, and everybody. Kat and I are sorry to leave without saying goodbye. We knew if we'd said anything, you'd try and stop us from trying to travel to Sonic's world. It's very important to us, so I hope you'll understand. Don't worry. I'll take care of Kat. We'll be fine. I will tell Penny you all say hi and that you miss her. And Kat and I will be back. We'll miss you all. Mom, Dad, Grandpa, Danny, Francis, Helen. I love you. Chris. And Kat. P.S. We'll tell Penny, Sonic and the others you say hi!

...

The Emerald blinked on and off.

Knuckles, Sonic, Penny, Tangle, Whisper, Cloud, Hiro, Cosmo, Silver, Amy, Cream, and Cheese watched with curiosity as two figures emerged from the portal.

"Hey, that's Chris and Kat!" Knuckles, Sonic, Penny, and Hiro gasped.

"I did it!" Chris cried. "I actually did it! Sonic! Penny!"

"Hiro! Penny!" Kat cried as well, looking at their friends' stunned faces. Chris and Kat fell to the ground. They looked at their baggy clothes, and their childish appearance.

Chris and Kat let out a startled scream.
