Earth, a planet home to millions of people and animals. But it harbors a secret no one else knows of. Except for few.

High above in space, a fleet of ships was stirring and floating above the blue planet. This was the fleet of an evil man.

The notorious Dr Ivo "Eggman' Robotnik. He has been planning this for months now. With his upgraded fleet, he was ready to invade Earth and take what is rightfully his. He laughed, knowing he cannot be stopped.

However, his laugh was cut off, when the alarms went off and something exploded at the edge of the docks.

It was an anthro type of animal. A blue hedgehog, with red sneakers and emerald green eyes.

For this was the one thing that could ever stop Eggman. The fastest thing alive.

Call him the blue blur, call him a speedster, the freedom fighter of his home and the earth. But he much rather prefers Sonic. Sonic the Hedgehog.

Eggman wasted no time in deploying his robots. Thousands of his new Egg Fighters swarmed up in front of his arch-nemesis. All of the cannons locked and loaded and took aim at the speedy Blue hedgehog.

"FIRE!" Eggman bellowed, throwing his arm out. At the command, all the cannons fired. Shells rained down on the dock like a hailstorm. Though, this was nothing to the hedgehog.

Moving faster than the speed of sound, Sonic rushed forward, dodging the hail of bullets that came after him. He then charged into the wake of the countless robots, hammering each one and evading their strikes with his homing attack. He then stunned a larger one and boosted into another wave, making them explode into junk pieces.

It was at this moment Eggman decided to enter the battle himself, crashing down in his own personal Egg Dragoon. He unloaded a barrage of bullets from the twin machine guns. Like the others, Sonic evaded the bullets like it was nothing. He peered around the giant machine and zipped further into the ship.

"You're not getting away!" Eggman said changing one of the gatling guns into a hand as it rocketed forth like a gassed up harpoon.

"Whuh-oh!" Sonic grunted as the hand grabbed him and pulled him back. Just when Eggman had him right then and there, Sonic closed his eyes and made seven colored jewels appeared.

"What?" Eggman knew what they were. They were the most powerful source of energy that is known to the world. The seven Chaos Emeralds. Knowing that Sonic has them, he knew he was in trouble big time. Trying to trap him, he was too late as sonic exploded outward in a flash of yellow light. He now was golden and flying in the air.

Sonic had become Super Sonic. With his incredible power, Sonic blasted forward and destroyed the robot like it was wet tissue paper.

"Uh oh, time to go!" Eggman said ejecting his Egg Mobile. He quickly closed the doors to give him some more time, but like his robot, Sonic blasted right through them like it was nothing. Behind him, the ship started to explode.

As the two made it out, Eggman's fleet was beginning to collapse. All that stood was a lone satellite. Eggman made it there, but he was soon cornered. Sonic blasted through the floor and smirked in triumph.

"S-Sonic!" The evil Doctor shouted. "I-I'm sorry! L-Look, go easy on me! I'll turn over a new leaf, I swear! Just give me a chance!" Eggman begged, bowing to the super charged hero.

"Well, this is new, showing remorse, Eggman? If you'd play nice, I wouldn't have had to break all your toys." Sonic said.

Sonic had been in many situations like this before. He always turned up and smashed whatever eggman was doing. But he didn't know that Eggman grinned and held something. That was the one thing Sonic never learned from all his battles with Eggman.

He always had an ace up his sleeve.

"Gotcha!" Eggman pushed the device he had in his hand. Different pieces of tech sprung out and binded Sonic in an energy ring. Not even his Super form was able to break him free.

Eggman laughed in triumph and he stood up. Soon, purple light shot out and shocked the hero, making him scream in pain. The pain was so intense, the seven Chaos Emeralds even responded to the massive amount of Negative energy.

Outside, the satellite opened up. It wasn't an ordinary satellite at all. It was an orbital cannon, and it was ready to blast all that energy right at the planet.

"Oh, i've waited a long time for this!" Eggman laughed.

As the cannon was being charged up, Sonic felt his body changing, and the Emeralds were losing their color and power.

"Fire!" Eggman said blasting the energy straight into the earth and spreading all a cross it. In the next instant, with a huge roar and splitting earthquakes, the planet ripped up into seven pieces. At the instant, massive tentacles of energy formed.

The electrical energy continue to blast through Sonic's body. He grunted in pain, and his body slowly started to shift. His muscular density increased, his fur doubled in capacity and thickened. Sharp claws and fangs formed in his hands and mouth. Where sonic was now, he had black fur and his sneakers were spiked at the bottom and rings.

Sonic was now a Werehog. He then roared loudly, as something formed out of the planet and roared as well. It was a being that existed at the very beginning of time when the planet was formed.

It was Dark Gaia.

With the plan a success, the machine's powered down and the emeralds dropped to the ground. They lost all of their power and were now black and dull, no sense of energy left in them.

"Success! A brilliant success! It's just as the Gaia Manuscripts foretold! The entity that was sealed within the planet has awakened!" Eggman explained. "Now, I just need to harness its power, and Eggman Land will finally come to be!"

Sonic staggered to get up.

"You've really... gone and done it this time, Eggman." Sonic growled with his voice more deeper and threatening than before.

"Ah, Sonic. That's a good look for you. Festive! Now, so long, friend!" Eggman shouted. He opened the airlock and tossed Sonic and the dead Chaos Emeralds out into the blackness of space, sending him tumbling towards one of the continents. As he did, Dark Gaia dissipated into smoke and spread his influence over the planet.

But it wasn't just limited to Earth. Its power reached across space, inching its way to a place that would always detect such phenomena.

Welcome to the Magical Land of Equestria, a land where Ponies rule, and peace, friendship and harmony thrive. And yet, this is where Dark Gaia's inch of power worms its way into the capital city, canterlot. In the throne room, the darkness reaches the rulers, Princesses Celestia and Luna. As it touches their bodies…

Celestia shuddered as she gasped in response to this surge. Luna too felt this new power, and it felt more dark and dangerous than any negative energy she felt in her life.

"Sister, did you feel that?" Luna said.

"I did. And I know what it is. IT… has resurfaced. Summon Twilight and the others, Hurry!" Celestia said to a guard.

"Yes, your highness!" The soldier saluted and ran off.

Later…

It didn't take long for the ones who guard the realm to get here, six special ponies bearing the most powerful source of magic in the realm. The elements of harmony.

Applejack, the Element of Honesty, a farm earth pony raised in the lands of ponyville and of the Apple family and the most trust worthy.

Fluttershy, the Element of Kindness, a Pegasus raised in Cloudsdale, with the kindest heart anypony can find.

Pinkie Pie, the Element of Laughter, an earth pony who was raised on a dull rock farm, and now a hyper pony, willing to spread joy and laughter to all those around.

Rarity, the Element of Generosity, unicorn and Fashion designer for her own Carousel Boutique. To her, no one in her eyes is one who needs help, be it fashion or otherwise.

Rainbow Dash, The Element of Loyalty, pegasus and one of the most fastest you'll find. She is a but of an egoist, but push comes to shove, she would never leave a friend behind.

And lastly, Twilight Sparkle, the Element of Magic and the Princess of Friendship. Was once a unicorn and was under the wing of princess Celestia herself. Now an alicorn, she is more than willing to carry out more duties than ever. And this one is no different.

"We came as soon as we could Princess Celestia! What's the emergency? Did Tirek break free again? Is Chrysalis back?" Twilight asked her mentor.

Celestia frowned and shook her head. "No, Twilight. I'm afraid there's a crisis that is even far more dangerous than the enemies you all encountered."

"Well, what is it?" Rainbow asked.

"Are any of you familiar with this creature?" Luna asked showing the image of Dark Gaia. The beast roared loudly, sending massive shivers down the backs of the bearers.

"Wh-what is that?!" Fluttershy stuttered, obviously being the most timid and most scared of the ponies in the group.

"I've seen what that thing looks like, but in one of the oldest books from the Royal sister library." Twilight said, looking more closer to the shape of the beast.

"This creature is known as Dark Gaia. It was sealed in the other world Twilight has been to retrieve her crown from Sunset Shimmer." Celestia explained. "However, someone awoken him, and now, he has returned."

"Well, that doesn't sound good at all, dont it?" Applejack said.

"It's not." Luna answered. "Dark Gaia is one of the most powerful beings known. He is strong enough to even rival beyond our own power."

Twilight was shocked to know this. A dark being, surpassing levels far beyond even Nightmare Moon or even the rulers of her world.

"Is there anyway to stop him?" The lavender alicorn asked, hoping there is a weakness.

"There is." Celestia nodded. "Dark Gaia was awakened too early, and he is still weakened. In his state, he is not at his full power."

"Then we still have a chance to take it down right? Then what are we waiting for then?!" Rainbow asked.

"Well, we could use the mirror, but… that'd just take us to where my CHS friends are, not anywhere in this world." Twilight mentioned.

"Actually, Luna and I have been studying the world while you all were arriving. We have discovered there is another gateway to another city that will help you go on the right path to stop Dark Gaia." Celestia said.

"The first city is here." Luna said showing a city on a cliffside near and ocean. It was covered in windmills. "It's name is Atopos."

"I would think this is the greatest threat to anywhere in the worlds. You six must stop this threat and reseal it immediately." Celestia said.

"Or the worlds are doomed, destruction, yadda yadda yadda…" Rainbow said. "We get it. We've done this before."

"Rainbow's right. And when have we ever failed to stop somepony who wants to destroy us or even take over Equestria?" Twilight said.

"Do not take this lightly." Celestia said in a stern voice. The ponies flinched a little by that. "Even if Dark Gaia is weakened, he is still very powerful. He even has an army of dark beings. They will not show you mercy. They will kill you. If any of you encounter him or his army, run. They are not to be taken lightly. Their power is greater than your own."

"I understand." Twilight said. "And we're ready."

"Good luck, all of you." Celestia nodded as the girls walked over to the mirror Celestia readied and they all stepped in.
