(Cue Sonic X intro theme)

(Rainbow Dash's dream world)

We come to the dream world of the cyan pegasus, and see nothing but darkness around her. "Where am I?" RD thought. looking around. She kept looking around, until seeing a black pegasus with a gray mane and tail, that looked exactly like her, except the this mare's Cutie Mark was that of a gray cloud and lightning bolt. "Why, hello there Rainbow Dash." The pegasus said in Rainbow Dash's voice, except it sounded evil. "Who are you?" RD asked, getting into battle position. The black pegasus just snickered at hearing the cyan speedster's question. "You'll know soon enough, Rainbow Dash, but until you do, I bid you farewell." The pegasus says. Suddenly, the black pegasus disappears from Rainbow Dash's view, and a sudden bright light from the darkness blinds her.

(Later that day in the real world)

After dealing with what Rainbow Dash saw in her dream, we find her walking around Ponyville. Though, after just barely entering the town, the rainbow pegasus sees something she despised...

Sonic and Amy... TOGETHER.

As per usual, the pink hedgehog was trying to convince the blue blur to date her. "Sonic, come on! Why won't you date me!" Amy complained. "For the last time Amy, I don't want to be in a relationship with you!" Sonic shot back. Of course, this annoyed Amy, and she brought out her Piko Piko Hammer. "You will date me Sonic the Hedgehog!" Amy exclaimed, pulling out her hammer. The second Sonic saw the pink hedgehog pull out her hammer, his eyes shrunk. He didn't wanna be squished! So as quick as a flash, the blue blur pulled out his Power Ring from his quills, before transforming into his pegasus form, and flying off, with an now angry Amy Rose on his tail. "YOU GET BACK HERE SONIC THE HEDGEHOG!" Amy yelled out, chasing the blue pegasus. Though, both hedgehogs were unaware that Rainbow Dash was watching the both of them, and this angered the cyan pegasus a lot...

AND I MEAN A LOT.

She was about to charge over there, and slam the pink hedgehog into the ground for chasing the one she loves, but she instantly stopped herself. Rainbow Dash didn't wanna have death in her hands! She was the Element of Loyalty for crying out loud! So without another thought, the cyan pegasus flew off to her cloud home.

(Sonic and Amy)

We join the two hedgehogs (even though Sonic is now still a pegasus...), and see that Amy hasn't given up her chase of Sonic. "Sonic the Hedgehog! You stop this instant and date me!" Amy cried out. Sonic looked back at the pink hedgehog from the air, and quickly retaliated. "No!" Sonic shot back. Of course, even with the blue stallion saying no, the pink hedgehog still continued her chase of him. It is until, Sonic suddenly turns back to his hedgehog form, and crashes onto the ground. "GAH!" Sonic exclaims, slamming onto the ground. The blue blur quickly gets back onto his feet, and runs off, trying to still avoid Amy. "Damn good time to run out of energy Power Ring..." Sonic mutters to himself. As Sonic continues to run, he picks up the pace to try and outrun Amy Rose like he always has. Finally, after awhile, the blue hedgehog finally hears the pink hedgehog from a distance. "YOU WILL BE MINE SOMEDAY, SONIC THE HEDGEHOG!" Amy yells out. Noticing this, Sonic finally screeches to a halt, and looks back from where he came from. Amy was nowhere near him. With this in mind, the blur blur ran off towards Twilight's Library, hoping to have Tails recharge his Power Ring...

(Meanwhile, at Rainbow's house)

After eventually arriving at her home, Rainbow Dash flew into her room, and slammed the door. Fortunately enough, Light Dash was there, and she quickly rushed over to her sister's room door. "Hey Dash, are you okay?" LD asked from outside the closed room. It was silent for a few seconds, before Light Dash managed to get an answer from her sister. "NO! LEAVE ME ALONE LIGHT DASH!" RD yelled back to her sister. Hearing her sister, the Alicorn complies with her wishes, much to her dismay. Inside Rainbow Dash's room though, things aren't getting better. The cyan pegasus is crying into her pillow, sad that she competition in order to get to Sonic. As she is doing this though, anger that was bottled up with Rainbow Dash has finally gotten to her, and her cyan coat was starting to turn black. It wasn't until her mane and tail were grayed out, until the pegasus looked up from her pillow, her eyes now fully white. "That pink hedgehog is dead..." RD growls under her breath...

(Back in Ponyville)

After eventually arriving at Twilight's Library, Sonic stopped at the front door of the library and opened it. Upon doing so, smoke from an explosion was sent into the hedgehog's face. "GAH!" Sonic exclaimed, covering his face from the smoke. After the smoke cleared, the blue blur finally discovered what caused the smoke and explosion...

Tails and Twilight, who were covered in dust.

"He-hey Sonic..." Tails says, nervously. "What happened with you two?" Sonic asked, curious. Sonic was immediately answered by Twilight who was fixing up her mane from the explosion messing it up. "We tried to fix Tails' arm cannon again... It blew up..." Twilight says, smiling nervously. Hearing this, the blue blur face palmed. "Heh, what am I going to do living with you two..." Sonic says, snickering a bit under his breath. Though, his snicker is cut off by the sound of someone screaming...

That scream coming from Amy Rose...

"SONIC! HELP ME!" Amy yelled out. At hearing this, Sonic immediately turned towards the open door of the library (which he hadn't closed...), and saw Amy running from... Something he couldn't see. Though, something came into the blue hedgehog's sight seconds later, and it was chasing the pink hedgehog! The thing was a black pegasus, with a Cutie Mark that was a gray cloud and lighting bolt. What was most mysterious though, is that the pegasus looked like Rainbow Dash! "You're dead Amy Rose!" The pegasus cried out in a voice that was almost similar to Rainbow Dash's. The black pegasus started to pick up speed, and aimed her body towards the pink hedgehog. Without a split second to think, Sonic ran towards Amy Rose, and grabbed her, causing the pegasus to crash into the ground. Anyway, after grabbing the pink hedgehog, the blue blur ran a few feet away from the pegasus, and set her on the ground. "You okay Amy?" Sonic asked worriedly. Amy nodded her head in reply, before running off, not wanting to deal with the black pegasus. Speaking of which, after seeing the pink hedgehog run off, Sonic turned towards the black pegasus, and finally got a good look at her...

The pegasus looked like Rainbow Dash!

"Who are you...?" Sonic asked, clenching his fists, and getting into a battle position. The pegasus snickered at hearing the blue blur, and looked over at him with her pure white eyes, before responding in a voice that sounded like Rainbow Dash's. "Isn't it obvious Sonic? I look like Rainbow Dash, talk like her, and have the same Cutie Mark. I AM RAINBOW DASH, but you may call me Dark Dash." The pegasus now known as Dark Dash responds. Hearing this, Sonic's eyes shrunk. He couldn't believe his ears! This pegasus was Rainbow Dash, but she was evil! "How... How did this happen?" Sonic asked, not leaving his battle position. Dark Dash snickered once again at hearing the blue blur, and simply answered him. "If you want to find that out, you have to beat me." Dark Dash says to Sonic. Hearing this, the blue hedgehog slightly let his guard down, and gasped. He couldn't harm the one he loved! But, if he wanted to protect Amy, and the ponies of Ponyville, he had to fight. "Fine..." Sonic mutters, getting ready for a fight.

(Cue Egg Emperor Bossfight theme)

Dark Dash opened up the fight, by charging straight towards the blue hero. "Heh, are you trying to make this easy?" Sonic asked aloud. Then, as quick as a flash, Sonic jumped up and Homing Attacked Dark Dash. This would have worked, that is, if the black pegasus didn't manage to grab the blue blur's leg just as the attack was about to make contact. "Uh-oh..." Sonic whispered. Before he could react in time, Sonic was thrown by Dark Dash, straight into the library wall! Though, this barely scratched the hedgehog, as he got back to his feet, and smiled. "You want to do this the hard way? Then lets do this the hard way!" Sonic exclaimed, running towards the black pegasus. "Hey! That's my line!" Dark Dash shot back, flying towards the blue hero. Just as the two speedsters reached each other, they both had disappeared into thin air. The only times they were seen, is when on of the two of them managed to land a punch on the other. It wasn't until Dark Dash released an energy ball upon Sonic, that this ended. "GAAAAAAAH!" Sonic yelled, falling to the ground. Now, the energy ball attack, being close range, did quite a lot of damage to the blue hero, as he struggled to stay on his feet. "Heh,heh... Is that all you got... Darky?" Sonic asked weakly, still trying to keep us his usual cockiness.

Of course, Dark Dash didn't take to kindly to this insult... "You're a dead hedgehog!" Dark Dash cried out, charging towards the blue hero. As she was doing so, the blue blur reached into his quills, and pulled out his Power Ring in an attempt to use its power to finish this fight... Though... He forgot one thing...

THE RING NEEDED TO BE RECHARGED!

Sonic notices this seconds too late, as Dark Dash slams her left forehoof striaght into the hedgehog's gut. This sends him flying back towards the library, and slamming into the outside wall, which sent up a lot of dust. Though, when the dust cleared, Sonic was still standing, though, he was coughing up blood... "That's it?... Nothing special...?" Sknic muttered, coughing up more blood before eventually smiling. "How... How are you still standing!?" Dark Dash asked angrily, looking over at the blue hedgehog. "Heh... That's... Simple... I won't let you... Harm anypony... Including *coughs*... My friends..." Sonic muttered, keeping his smile.

(End Egg Emperor theme)

The black pegasus finally had enough of the blue hero, as she slowly walked towards him, charging up one last energy ball, that will surely kill the hero. Though, just as she was five feet away from him, Rainbow Dash's voice intervened from inside the pegasus. "I.. Won't... Let you... KILL HIM!" RD's voice yelled out from inside Dark Dash's head. Then, just before anyone could react, the black pegasus stood on her hind-hooves, and grabbed her head in pain. "GAAAAAAAH!" Dark Dash screamed. The black pegasus struggled to walk on her hind-hooves for a couple of seconds, before collapsing onto the ground. After this, a black aura surrounded her, and when it disappeared, Rainbow Dash was in the place of the black pegasus. "Heh... She's back..." Sonic muttered, smiling confidently. Though, his smile stops shortly, as the injuries from the fight are to much for the hedgehog, and he collapses, and falls unconscious from his injuries...

(LAAAAAAAAAATER)

That evening, we arrive at Ponyville Hospital (calling it that!), and see Sonic the Hedgehog unconscious, and bandaged up, in one of the patient rooms. Sitting near him, is Twilight Sparkle, for she brought him to the hospital. "When is he going to wake up? He woke up sooner the first time I brought him here!" Twilight thought. Then, just like her thoughts were heard, the blue hedgehog woke up, clucking his head in pain. "Ow... Where am I?" Sonic muttered, opening his eyes, and looking around. After some looking around, Sonic finally saw Twilight, and sighed in annoyance. "Dammit... I'm in the hospital again, aren't I?" Sonic asked. The alicorn nodded in reply, and the blue hedgehog sighed again in annoyance. Though, it only took him a few seconds to realize something...

Why wasn't Rainbow Dash here?

"Hey Twi, where's Rainbow Dash? I would have expected her to be here to apologize for what she did." Sonic said to Twilight. Hearing the hedgehog, Twilight smiled nervously, before answering him. "Well... She would be here... That is... If she didn't run off into the Everfree Forest!" Twilight exclaimed, saying the last part quite quickly. Even though the last part was said quickly, Sonic knew what Twilight said, and his eyes shrunk. "WHAT!?" Sonic yelled.
