Author's Note: I'm currently rewriting and editing this story. The changes are radical and the story will be much different (and much better) when the revisions are done. As of 1/27/20, everything up to Episode 70 is finished. I strongly suggest not reading further until I delete this message. If you do, be aware that the other chapters that haven't been mentioned are highly incomplete.

I do not own Sonic and friends as well as the Metarex and Sonic X, they are all owned by Sega, Sonic Team, and all respective owners.

Sonic X: Dark Chaos

Episode 53: The Cosmic Messenger

Super Sonic dodged and weaved around the relentless attacks of his mysterious opponent, several hundred miles above his home planet of Mobius. With no earthly physical limits, the cold vacuum had become his arena.

A jet-black fox, Sonic's utterly dogged opponent, let up on his attacks and floated still. With apparently limitless determination, this opponent was so powerful that not even Super Sonic could defeat him.

I gotta finish this quick, Sonic thought, as he prepared to fight again. The black fox also readied himself for yet another barrage of aggression.

After a short pause, they both flew at each other with extreme power, lighting up the sky with their impact. Sonic was thrown back, and he felt his power draining as he got more tired by the second. Unfortunately, his enemy looked completely unaffected.

Sonic knew the only way he could save the Emeralds. He stretched out his hands, and the seven glowing Chaos Emeralds appeared around him.

"Chaos Control!"Sonic yelled across the heavens, and at his command ever single gem shot across space to parts unknown. The black fox seemed unfazed by Sonic's move.

Sonic, all out of energy, lost his super form and collapsed, his body hurtling through the atmosphere. The black fox, however, remained. He looked down on the planet with loathing in his eyes.

That's when he noticed a blow. He put his gloved hand to the sparking hole in his side. Blue-tinted ichor stained his hand. From the deepest recesses of his mind, a voice called out to him as if the speaker stood nearby.

"You vitals have dropped. What is your condition?" It spoke in an arcane tongue that cannot be written with human vocabulary, but the recipient understood.

"A yellow hedgehog ambushed me," The fox replied, "Filled with the power of Chaos and ferocious in wrath."

"Repair yourself. Do not go further. Leave this world untouched. This hedgehog is not to be underestimated."

Without responding, the fox turned and flew away.

...

Down on Mobius, it was a quiet night, and Tails, Amy, and Cream were all on a hilltop. Tails had set up a video camera, as there were about to observe a beautiful meteor shower.

"How much longer do we have to wait?" Cream asked.

"I'm not sure, Cream. Not long I think," Tails assured.

"This is so romantic... if only Sonic was here to see it with me!" Amy fantasized. "Soon the whole sky will be filled with shooting stars!"

"According to the astronomers, we only get a meteor shower this large only every five hundred years or so. We're really lucky to be here." Tails explained.

"I surely wouldn't want to wait that long to see it again. Would you?" Cream said to her chaos, Cheese. Cheese replied with a little reply of "Chao!"

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

Tails turned around. "Why?"

"Chris told us that if you wish whenever you see a shooting star, it'll come true! Remember?" Cream explained.

"Yeah... It's too bad Chris and Chuck aren't here to see this with us," Tails said sadly.

"I miss them. I wish I could go back to their world," Cream wished.

That's when they all spotted a white ball streaking across the sky. Then another. Then more.

"Hey, it's starting!" Tails said, and readied the video camera. Instantly, what seemed to be thousands of bright-white streaks filled the sky in a stunning display of light.

"They look like fireworks," Cream commented.

"I'm sure glad I brought a camera." Tails also commented. That's when they noticed a meteor that almost seemed like it was coming straight towards them.

"That sure is a strange one..." Amy commented.

"It looks like it's-" Cream added.

"Get down!"

All three instinctively ducked as the "meteor" sailed over their heads behind a nearby hill. A gigantic explosion, accompanied by a mighty rumbling blast, echoed over the horizon as the "meteor" hit the ground.

Surprised, Amy, Cream, and Tails ran over to the impact site, weaving around flattened trees laying all about. They saw that it wasn't a meteor at all; it was a tiny spacecraft, obviously damaged beyond repair thanks to the copious amounts of smoke billowing from the hull.

However, the most interesting discovery lay a few feet in front of it. A small girl with green hair lay motionless in front of the wreck. Tails ran over to her and held her, checking her vitals; she made a small moan in response.

"It looks like she needs help," commented Tails.

"Here, let's take her to Cream's house," Amy suggested.

...

Sonic woke up to find himself lying on a bed; he was weak, and he felt morbidly tired. However, his alertness overcame him, and his eyes snapped open.

"It's about time that you finally came to," Sonic heard a familiar voice from his right. Sure enough, in a nearby revolving chair sat the burly Dr. Ivo Robotnik.

"Eggman... What happened?" Sonic asked the man.

"I've been sitting here for the better part of a week waiting for you to wake up and tell me," Eggman said, "I went out for a jog along the beach, but I spotted you nearly dead on the sand. It was a difficult choice; I had to decide whether to save you, or wait for the tide to come in. Ohohoho!"

"You were in terrible shape, Sonic. Dr. Eggman saved your life," the small gray robot known as Becoe popped out of nowhere.

"If he hadn't, he wouldn't have had anyone to fight," Decoe also popped up. For some reason, Decoe and Eggman shrugged. Bokkun, holding a glass of something, flew down in front of Sonic.

"So how did you end up on the beach, anyway?" Bokkun asked.

"... I... I was fighting somebody in my Super form." Sonic answered. He stood up; by accident, he knocked Bokkun's drink out of his hand, which splattered all over the robot's face.

"Hey, sorry, but I can't say anymore!" Sonic apologized, and started to speed away.

"You're leaving already?" Robotnik asked.

"See ya later, Eggman!" Sonic said, and sped off.

"Hey, you owe us, Sonic!" Decoe yelled after him.

"Get him!" Bokkun yelled.

While all three of his worker robots just kept shouting and yelling at Sonic, Eggman simply wondered who Sonic got in a battle with; whoever it was, it was certainly more powerful any other, for Sonic had never been defeated as Super Sonic. He was intrigued, and part of him wished his nemesis had said more.

From the vent just above him, unbeknownst to Eggman, he was being watched by a familiar treasure-hunting bat.

...

Cosmo was running through the dark corridor of a ship; running from what, she did not know. She ran and ran, and felt like her lungs would burst.

Suddenly, an blue-colored explosion in front of her knocked her back. In the smoke, she saw the very one she was fleeing from; a black fox, stoic and ruthless. As the fox turned its head around, its dark-blue eyes full of hatred and loathing turning towards her, and they glowed blue, indicating that the fox was about to use some kind of Chaos power.

Cosmo was shocked; she couldn't to anything but cower. She was too scared to even move.

"COSMO, RUN!"

She regained consciousness and snapped out of her dream. Her vision was blurry. She heard a voices by her, but she couldn't understand them in her condition.

Cosmo slowly got up, feeling tired and weak. She noticed several figures beside her bed; a pink hedgehog and two rabbits; one tall, one short. However, she then noticed what she was fearing the most; a fox with two tails.

"GAAH!" She screamed in fright as she locked eyes with Tails; she thought it was none other than her worst nightmare.

Tails, along with the others, recoiled in surprise from her reflexive reaction. "Whoa! Are you okay?"

Cosmo then realized that this fox couldn't possibly be her nemesis; he didn't have his voice nor his mannerisms. She calmed down slightly, relieved that her first impression was wrong. "Wait... You're not Tsali..."

"Tsali?" Tails asked, not recognizing the name.

"You were in a big crash. You're really lucky you came out of that crash alive," Amy changed the subject.

"Maybe you could tell us your name and where you and your ship came from?" Cream suggested.

Cosmo seemed a bit scared, "I can't say..."

"You mean, you can't remember?" asked the rabbit.

"I can remember, but I... can't tell you." Cosmo answered shyly.

"Why?" Tails asked.

"I am looking for someone on this planet named Sonic the Hedgehog. It's crucial that I speak to him before it's too late." Cosmo answered.

"You can talk to us. We'll help you if we can. What's the matter?" The fox offered.

"I... I can't tell you," Cosmo rebutted him.

"Well, I have a right to know what this is all about! Sonic's my boyfriend, and you better not try anything," The pink hedgehog shouted. Cosmo was just stared at her.

"Amy! Don't be rude. I don't think she came here to date him," Cream held back the hedgehog.

"We're friends of Sonic, so maybe we can help," said Tails.

"Friends?" Cosmo asked.

"My name is Miles Prower, but everybody calls me by my nickname, Tails." Tails introduced himself.

"And I'm Cream. It's very nice to meet you," The small rabbit introduced herself.

"And my name is Amy Rose! You're not gonna be here long, are you?" The pink hedgehog said in a still-stern voice. Cosmo just felt a bit scared, while Tails and Vanilla sweatdropped.

Suddenly, everybody heard a rumble, and everybody went to look out the window. The dark night sky suddenly glowed a bright blue as a shimmering ball of blue light streaked across the sky towards the planet.

When it impacted the top of a nearby mountain, a large blue explosion bloomed over the rocks, and from that explosion, a strange black fox appeared, floating in the air. It appeared to be looking about for something.

"What is that?" Cream asked.

"I don't know. It looks like a strange black fox..." Tails replied, trying to get a better look, "And... and he has two tails, just like me!"

"You should stay in bed." Vanilla said behind them. They noticed Cosmo had gotten out of bed, and wanted to see what was the commotion. As soon as she looked out, she almost fell back in fear.

"So, he finally found me..." Cosmo muttered, "Tsali's vengeance... has come to take me."

That's when several lightening bolts appeared, and without warning, areas of the forest exploded into brilliant azure flame. The blue inferno soon spread, spreading everywhere in seconds with a terrible whoosh.

"What the...! What's he doing?" Amy shouted.

Amy, Tails, Cosmo, and Cream all ran out of the door, and ran into the intact woods to see what was going on.

...

Meanwhile, on Angel Island, Knuckles the Echidna slept soundly on the hard stone steps in front of his beloved Master Emerald, but he was awakened by the explosion. He woke a sat up, and stared in wonder as the fox revealed himself in the fire. The fox descended closer to the ground, just above tree level.

"This looks like-" Knuckles muttered. Tsali's eyes glowed.

The black fox held out one of his hands. Without warning, a wave spread across the ground that uprooted and vaporized every tree and shrub in its path. Knuckles covered his eyes, as the ground shook and arcs of blue lightening bolts flashed across the ground. Soon enough, the verdant forest was a now raging conflagration of cobalt flames.

"This guy's gonna burn up every tree in the forest!" Knuckles said. He stood up and immediately leaped in the direction of his new foe. "Hey, knock it off!"

The fox sensed something about to attack him.

Knuckles flew up behind him, preparing for a swift kick. However, without warning, he felt some invisible force yank him backwards, like a magnet repelling another magnet.

Now the fox sensed his prize. He flew up into the air, and from heaven he unleashed a furious torrent of energy bolts. With the sheer power of his strike, the ground shattered, and a small, galaxy-like object inside a crystal was revealed in the crater.

The fox floated down and grasped the object. It glowed in his hands as he leaped off into the woods. He admired his prize; the item he needed as energy harvesters, the fuel for the flames that would burn the galaxy. The crystal glowed slightly, and the glass sphere around it shined in the pre-dawn light.

Suddenly, he sensed a small group of figures approaching his location; in a nearby clearing stood another fox, a pink hedgehog, and small orange rabbit, and... Cosmo.

Cosmo immediately cowered behind Tails and Cream.

"Alright, you two-tailed fire freak!" Knuckles landed next to his friends. The black fox did not say a word. Everybody focused their attention on the new villain.

And just then, a familiar blue blur shot out of the flames and into view.

"Sonic!" Amy cried, her face instantly radiating with joy. Knuckles was the only one who held her back from glomping the blue hedgehog. He jumped down into the clearing, closer to Sonic and his friends.

"Who the hell are you?" Knuckles demanded. He still did not speak.

"... My name is Tsali, and I am the Ultimate Weapon. Do not forget my name as your world burns," The fox introduced himself, and pulled out a strange object. The heroes recognized it as a Chaos Emerald, but it didn't have the same color as any of the Chaos Emeralds. It was jet-black, just like Tsali's fur.

Knuckles suddenly started to glow red with anger, his power increasing sevenfold.

"You'll regret coming here and trashing our planet!" He violently charged towards Tsali with savagery on his mind.

However, as soon as he was about to punch, Knuckles was thrown away by a simple stationary swipe. Tsali didn't even bat an eye.

Sonic took a step forward, but faster than his eye could see or his body could move, Tsali disappeared and suddenly reappeared behind the group. He then disappeared and then reappeared again, teleporting back to where he started.

"He can use Chaos Control...?" Sonic muttered in disbelief. He then gathered his will and, trying to do something to help his friends, charged. However, he felt something stop him, almost like an invisible brick wall. Without warning, he was shunted away with incredible power, much more than he could normally handle. Sonic went flying over the trees.

"Here guys, I'll help!" A loudspeaker-amplified voice came down from above; Tails and Cosmo in the X-Tornado were flying down at them. Tsali simply watched it with almost quiet interest.

The X-Tornado's guns ripped through tree trunks of rocks. Plumes of dust came from the strafing, but Tsali was completely unharmed, even though several bullets hit him. The high-velocity rounds had literally pinged off of his skin harmlessly.

Several missiles shot from the Tornado, but as they hit Tsali, their explosions simply faded off, and Tsali was unharmed. In reply, Tsali held up his right arm so that it was aiming at Tails. A secret hatch that was covered with black fur suddenly opened up in his wrist, and out of it, an extremely tiny multi-barreled personal cannon popped out.

As the back end of the wrist weapon opened, Tsali slipped his black Emerald inside and shut it, the weapon rapidly beginning to glow blue with Chaos Energy. The black fox aimed carefully as his wrist-gun began glowing a bright blue.

Instantly, he opened up; the weapon fired a hurricane of blue Chaos Spears right up at Tails's plane. Tails attempted to dodge the veritable anti-aircraft fire of their enemy as the black fox unleashed a furious storm.

Sonic attempted to get him while he wasn't looking, but Tsali sensed him coming; thus, he turned and opened up on Sonic instead. The blue hedgehog took cover from the hail of deadly cobalt bolts, which proceeded to brutally tear up everything behind the hedgehog.

By now, it was almost morning, and the sun was rising. The sky was beginning to turn bright and blue, even as the smoke for the battle began to rise. Tsali suddenly held fire, opened up his personal wrist cannon, took his Emerald out, and closed it. The weapon retracted into Tsali's arm.

Then, as if distracted by something, he paused and held his hand up to his ear.

Unknown to his opponents, he heard the voice again. "I see your disobedience, worm. Depart from this world at once. Do not tempt my displeasure."

Tsali conceded to the command. He crouched, a wave of blue Chaos Energy rippling through the ground in a radius of several feet. He immediately shot up at light-speed into the sky, a blue blur going up and up.

"Hold it!" Sonic said, jumping up after Tsali.

Tsali said nothing in reply, but he pointed his finger down at the hedgehog. Promptly, a dozen azure Chaos Spears appeared from thin air and launched at him. Sonic was hit by one of them and knocked to the ground.

"I got ya!" Knuckles yelled, and, with a football dive, he caught Sonic while skidding on the ground.

Everybody suddenly realized that all the plants and the trees were starting to wither and die. They simply stared dumbstruck as everything began to slowly wilt and turn barren in a few seconds.

"He's got the Planet Egg!" cried Cosmo.

"Planet Egg?" Tails asked.

"It's the life force of your planet. It's the thing that gives your planet the power to sustain life. Without it, everything will soon perish. You have to get him, fast!" Cosmo explained.

"Uhh... Okay then." Tails pushed the throttle as fast as it could go and raised the plane upwards, giving chase to Tsali.

Tsali, with his impressive speed, was very very far ahead of Tails; Tails wasn't sure if his plane could handle the altitude. Slowly but surely, Tsali got farther and farther away, and soon enough, he exited the Mobian atmosphere.

"I can't go any higher, this plane wasn't designed to travel in space." Tails said, but he heard whimpering behind him.

He looked backwards, "Cosmo, are you alright?"

"I'm just... a little... dizzy." Cosmo said, shaking it off.

"Sorry. I just wish I got the Planet Egg back." Tails said. Cosmo, for some reason, was starting to open the cockpit.

"Hey, could you open this? You can open it while you're flying, can't you?" Cosmo asked.

Tails seemed a bit confused by her question. "Yeah, but I'm not sure it's such a good idea at this altitude."

"Please, Tails?"

"Well, if you really want me to." Tails gave in, and opened the cockpit glass. Wind whooshed around, making Tail's fur and Cosmo's green hair whip from the wind.

"There you go!" Tails said, squinting, but to his shock, he saw Cosmo climbing out of the seat. She jumped off the plane, and hurtled through the sky for several seconds before her skirt unfolded and she slowly floated to the ground. Tails was a bit surprised at her maneuver, but he simply shrugged it off and flew back down towards the planet.

He started to fly towards Angel Island, when he noticed something flashing.

"Hey, what's that?" Tails muttered.

He suddenly realized that it was the Master Emerald, glowing on and off for some reason. Tails went off to land his plane and get the news to Sonic.

...

"You didn't put up much of a fight against that guy, Sonic. Are you sure you're feeling okay?" Knuckles asked. They were talking in the black remains of the forest.

"You don't seem like your old self." Amy added with concern.

"It's been a long day, so I guess I'm a little tired... Huh?" Sonic said. Everybody looked up; they saw Cosmo softly descending, using her skirt as a makeshift parachute. She landed and brushed off her skirt.

"There you are. My name is Cosmo. I need to speak with you Sonic." Cosmo said to Sonic.

"... Okay." Sonic said after a short pause.

"I have sought you out because I know you have the power to control the Chaos Emeralds. I came here because I know that you are the one who can save the galaxy from the wrath of Tsali." Cosmo explained.

"Uhhh... I am?" Sonic asked incredulously.

"Hey guys! It's happening!" a voice called out from behind Sonic. From a ways away, Sonic saw Tails running towards them.

"What's happening now?" Knuckles asked.

...

Sonic and his friends were all around the Master Emerald, staring at it as it flashed. Soon enough, a small black figure appeared inside of it. Everybody watched closer.

That's when Sonic and Knuckles realized who it was, and what was happening before their eyes.

"Is that-" Amy wondered.

"... It worked... I-I did it... I actually did it..."A young voice spoke from the Emerald. Without warning, a human boy appeared, and fell down. His oversized clothes sagged all over, now several sizes too big for the person who arrived.

"Chris!"
