Rainbow Dash and Sonic's Adventure

Rainbow Dash pursued the light-gold hedgehog in front of her. He resembled Sonic, except for the fact that his spikes were sticking up and he wore skates. There was also another unusual characteristic about him, he wore rings on his wrists and ankles.

"I wonder if he's from Sonic's world..." Rainbow Dash muttered to herself.

Suddenly, the hedgehog came to halt in front of an echidna. Rainbow Dash hid in the forest below.

"So, you're the reason I'm here." the light-gold hedgehog growled.

"Yes, Shadow." the echidna chuckled.

The echidna was purple with a peach-colored iris. He was dressed in some type of ancient tribe clothing. It was strange that it could fly, but, Rainbow Dash just watched.

"How do you know my name!?" Shadow gasped.

"All in due time... so, I'm assuming you came here to face me." the echidna snickered.

"Enough talk!" Shadow replied, charging up a sphere of energy.

"Well, you my friend, will not get far!" the echidna still spoke in his snide, yet, confident tone.

"Chaos Sphere!" Shadow shouted, unleashing the attack.

The echidna slammed the attack with his bare fist, reflecting it back on Shadow. The hedgehog was hit causing him to fall into the forest with the Chaos Emeralds.

"Ah... such a waste of powerful Chaos energy." the echidna sighed. "Now, to go look for that pony the legend foretold of."

He flew away, not seeming caring about the Chaos Emeralds below him. Rainbow Dash quickly gathered up the emeralds before Shadow could recover. She flew back to the castle. Sonic was still lying outside, the same place that he was killed. Princess Celestia, Shining Armor, and Princess Cadance hadn't left his side.

"You have them?" she asked.

Rainbow Dash nodded, and didn't waste any time placing the Chaos Emeralds in a circle around Sonic. She backed up, waiting for them to work their magic, nothing happened.

"Why isn't it working!?" she demanded.

""The servers are the seven Chaos. Chaos is power, power enriched by the heart. The controller is the one that unifies the Chaos." Princess Celestia recited. "I cannot help you beyond there."

The Chaos Emeralds floated up, along with Sonic's body. Princess Celestia motioned Rainbow Dash to do her job. She nodded and walked up to Sonic.

"Power that is unified by the heart..." she whispered.

She then carefully kissed Sonic on the lips. The two were covered in a blinding, white light.

"The magic of friendship..." Princess Celestia murmured, her eyes closed.

All of Ponyville was now outside, their mouths dropped in awe. It's no secret now that there is something big at work. As soon as quickly as it has started, the light faded. Sonic was floating, his fur was gleaming a gold light. He was surrounded in a light-gold aura. His emerald eyes had turned red. He was in his super form! Rainbow Dash's eyes filled up with tears as she looked at the revived hedgehog.

"Thank you, Dashy..." Super Sonic muttered as he hugged her.

"Sonic!" a deep voice called.

Super Sonic looked towards the voice. It was Shadow, who looked as ready to go as ever. Super Sonic flew over to him, and then shared his super energy. Shadow turned back into his super form.

"Wait! So we're teaming up with the bad guy?" Rainbow Dash asked.

"No, the real enemy is the echidna." Shadow said.

"Then what are we standing around for!? Let's kick some echidna butt!" Sonic shouted.

"Let's do this!" Shadow replied.

"I'm ready!" Rainbow Dash said determinedly.

The three fighters sped off into the sky.

"Princess Celestia! I just got word that the Crystal Empire has just lost all power! The ponies are exposed to the freezing cold and they're acting just like they did just before we defeated King Sombra!" Shining Armor informed.

"You and Princess Cadance go aid them." Princess Celestia replied gravely.

Shining Armor nodded, and then ran out of the castle grounds with his wife.

"Good luck, Sonic and Rainbow Dash..." Princess Celestia murmured.

***

The trio arrived at the now snow-covered Crystal Empire. The blizzard was harsh, but they ignored it.

"He's here... I can feel his Chaos aura." Super Shadow said.

"So, you've returned for me." a voice sneered. "And in your super forms too."

It was the mysterious echidna.

"Who are you!?" Super Sonic demanded.

"If you must know, my name is Taimuwāpu*." the echidna sighed like it was nothing.

"You must be the ancient evil! You're going to pay for what you've done to Equestria!" Sonic growled.

He zoomed over to Taimuwāpu and landed a punch right on his forehead, blowing him backwards. Taimuwāpu stopped himself in midair with a large shockwave, pushing Super Sonic backwards. Super Shadow grabbed his wrist and stopped his backwards journey.

"Hmph! You're weakness disgusts me!" he mocked.

"You two can pull any trick you please, but, I've seen it all before." Taimuwāpu shook his head.

"Sonic's moves may be predictable, but I'm the ultimate life form!" Super Shadow exclaimed as he charged up in a circular blue light.

Sparks of blue energy started to fly from his body. Super Shadow targeted the blue light towards Taimuwāpu and then fired several spheres. Before any of them hit the echidna, he disappeared into thin air.

"What!?" Super Shadow exclaimed.

Suddenly, Taimuwāpu reappeared behind Super Shadow.

"Look out!" Rainbow Dash cried.

But it was too late. Taimuwāpu punched him in the back. However, before Super Shadow was sent flying through the air, he powered down to his normal form. He flew through the intense blizzard. Taimuwāpu powered up in a light-gold aura and then flew after Shadow at a dangerous pace. When he caught up, he kicked Shadow into the icy ground below. The black hedgehog's body left a crater.

"He absorbed his energy and used it at his own advantage!" Rainbow Dash gasped.

"That's right, you foolish pony! So, Sonic! Are you ready to give up your super form to me?" Taimuwāpu sneered.

"No way!" Super Sonic shouted determinedly.

"You're annoyingly stubborn, Sonic, you always have been." Taimuwāpu sighed.

"And that's how I'll stay forever!" Super Sonic retorted.

"We'll see about that!" Taimuwāpu growled.

"Chaos Control!" Super Sonic yelled before disappearing in a blue light.

Taimuwāpu sighed and then disappeared in the same blue light. Both the hedgehog and evil echidna ended up reappearing and colliding together in the middle. Super Sonic dodged punch and kick Taimuwāpu threw at him, being careful not to let him drain his energy. Finally, Super Sonic got ahold of his leg and threw him into an iceberg. Rainbow Dash busted through the block of ice, causing Taimuwāpu to be tossed back to Super Sonic, who just kicked him back to her.

"Dashy! Hold him off!" he yelled.

Rainbow Dash did a quick nod before punching Taimuwāpu in the face. Super Sonic found this as an opportunity to fly into space.

"You're finished!" he shouted before spinning up into a ball.

When the attack was powerful enough, he let himself fall to the planet below him. Just as the enviroment was getting to the slightly sunlight sky, a hand reached out and stopped the ball of fury. Super Sonic could feel himself power down to his normal form and all the Chaos Emeralds fell to the icy plain below.

"Prepare to meet your doom, Sonic the Hedgehog!" Taimuwāpu's voice yelled.

A minute earlier...

Rainbow Dash was trembling from the cold and absolute terror. Would Sonic die? Taimuwāpu had left her stuck in some deep snow, unable to save Sonic. Just as she saw the echidna flying to kill him, she heard a voice.

"Rainbow Dash!"

She turned her head to the sound of the call. It was all of her friends, as well as Shining Armor and Princess Cadance.

"Guys! I need to save Sonic!" Rainbow Dash hollered.

"We know! Shining Armor told us everything!" Twilight's voice replied.

Rainbow Dash saw a necklace float in front of her, it was the Element of Loyality!

"We can't help much, but, we can be of assistance in this matter!" Twilight said.

"Prepare to meet your doom, Sonic the Hedgehog!" Taimuwāpu's voice yelled.

"Hurry!" Rainbow Dash cried.

Back with Sonic...

Before Sonic knew it, he was spiraling down once again in a spin ball. He knew at the rate he was going, as soon as he'd hit the ground, he knew that he'd die from the impact. And judging by how broken the poor hedgehog would be, not even the Chaos Emeralds could fix him. Was he to die right here?

Back with Rainbow Dash...

The Elements of Harmony floated around the pony.

"Element of Kindness!" Fluttershy said in her loudest voice.

The Element of Kindness attached to one of Rainbow Dash's ankles.

"It's happening! Keep going, girls!" Twilight encouraged.

"Element of Generosity!" Rarity yelled.

The same thing happened with the Element of Generosity.

"Element of Honesty!" Applejack shouted.

The apple-encrusted element attracted to one of Rainbow Dash's remaining ankles.

"Element of Laughter!" Pinkie exclaimed in her joking tone.

Despite the way she said it, the Element of Laughter still did its job. The ponies could now see Sonic falling in a rage of fire because of his speed.

"Element of Magic!" Twilight called.

The beautiful tiara flew onto Rainbow Dash's head.

"Element of Loyalty!" Rainbow Dash finished.

Her Element of Harmony attached to her neck. All of the elements lit up at once.

"Ahhhhhhhhhhhhh!" Rainbow Dash screeched as an explosion of gold light boomed from her body.

Sonic was almost to the ground when a circle of gold light sped out of the explosion and caught the falling hedgehog.

"Wha-" Sonic gasped.

The gold light disappeared. Sonic had been saved by Rainbow Dash, who was now completely white and her mane and tail were both sticking straight up. Her magenta eyes had turned red and her wings were way bigger. Also, all the Elements of Harmony were displayed on her body. She had transformed into the never-before-seen Super Rainbow Dash!
