Meeting...Yourself?

Chapter 1: Meeting...Yourself?

"Where's that damn 4th Chaos Emerald?" asked a flying robotic hedgehog. Ever since it lost to it's organic counterpart, this robot had been searching for the 7 mystical Chaos Emeralds. It had already found three emeralds, but was having terrible luck finding the other 4.

"Dang it, if I am to defeat my loathsome copy, then I must obtain all 7 Chaos Emeralds...wait, my emerald tracker is picking up something!" exclaimed the robot as it made it's way to the source of the signal it was getting. After landing in a field, it happened to discover the other 4 emeralds scattered all over the area.

"Something seems off, but this must be my lucky day." the robot said as it made it's way towards the emeralds. Suddenly, however, the emeralds it had as well as the 4 on the ground started glowing. A portal suddenly appeared and all 7 emeralds were sucked into it.

"What!? No, I must have all of the Chaos Emeralds!" it said as the robot sped into the portal, with the portal closing behind it. However, it's rockets started to malfunction, causing the robot to go the wrong way.

"NOOOOO!!!" yelled the robot as it lost track of all 7 emeralds. Wherever it ended up at, it planned on getting all 7 Chaos Emeralds no mater what.

"Ahhhhh, that was a great nap! I feel like a million bits!" said a rainbow maned and tailed pegasus. Rainbow Dash had just woken up from her usual nap and was right now stretching her wings when she saw her old fillyhood friend Fluttershy fly up to her.

"What's up Fluttershy?" asked Rainbow Dash.

"Twilight asked me to find you. She said she found something interesting and asked me and Applejack to get everypony together and meet at the library." said Fluttershy. This got Dash's attention. If whatever her friend Twilight Sparkle found needed her to have all of her friends get together, then it was obviously something big. Without much hesitation, Dash flew at incredible speed towards Twilight's house. When she got there, she saw that everypony else had already arrived. Fluttershy flew in a few seconds later.

"Looks like we're all here now." said Applejack.

"I wonder what Twilight found." asked Rarity, who was obviously curious.

"Oooh, maybe she found some sort of new spell that turns anything into candy!" said Pinkie Pie.

"Pinkie, you're so random!" said Dash, who was quite use to Pinkie's randomness. Soon, after some waiting, Twilight and Spike walked into the room, with Spike carrying 7 different colored gems. Spike set down the emeralds in the following order: red, blue, yellow, white, cyan, purple, and finally green.

"Sorry to make you wait everypony, but I've been trying to figure out what these gems are." said Twilight.

"Whatever they are, I can't even bite into them." said Spike while showing one of his teeth, which looked to be damaged.

"Whoa nelly, if Spike can't even eat these gems, then they must be powerful." said a surprised Applejack.

"I can feel some sort of power come from them too....what are they?" asked Fluttershy. Even she was surprised by what Spike just said, but was right now hiding behind Rainbow Dash, a little scared of the power coming from the emeralds.

"I've read a lot of Daring Do books, but I don't think any of them mention these." said Rainbow Dash as she reached out to pick up a emerald.

"Wait Rainbow, stop!" yelled Twilight, but Dash had already touched one of the emeralds with her hoof and suddenly, all 7 of them started glowing.

"Rainbow Dash, what did you do!?" asked Rarity.

"I don't know! I just touched one of them!" yelled Dash. Suddenly, a bright flash came from the 7 emeralds and enveloped each one of the ponies as well as Spike.

"AHHHHHHHH!!!" all of them screamed as they suddenly disappeared.

"What's this? I sense that a Chaos Control teleportation has just occurred." said the robot. After coming out of the portal that took the Chaos Emeralds away from it, it had been searching for them for a while. The land it was in was unfamiliar to it. It then looked up in the sky and saw another portal open in the sky. Coming out of the portal was 7 figures as well as 7 glows, but the 6 of the glows suddenly scattered away, leaving the 7 falling figures with one glow.

"At least I now know where one emerald is. Time to get what is mine!" the robot said as it sped towards where it sensed the crash was going to be at.

"TWILIGHT, WHAT DO WE DO!?!?" yelled Applejack as her and the others fell towards the ground below them. Both Rainbow Dash and Fluttershy were trying to use their wings to stop themselves from falling, but were having little success.

"I'M TRYING TO STOP THIS!!!" yelled Twilight as she tried to use her magic to stop them from falling, but panic was keeping her from doing so. However, right before they hit the ground, a force field appeared around all of them and slowly lowered them to the ground.

"Thank goodness you stopped it Twilight darling." said Rarity, obviously relieved that she wasn't going to fall to her doom.

"Yeah Twilight, way to go!" said Spike.

"Umm, T-Twilight...Umm, could you please do that a little earlier if there is a next time?" asked Fluttershy, obviously scared after what had just happened.

"Uhh, girls.....I'm not doing this." said Twilight, which obviously confused the others. The force field looked the same as the one Twilight would use, but when they looked at Twilight's horn, it wasn't glowing at all.

"Who the hay are you all?!" yelled an unknown, yet familiar sounding voice.

"Rainbow Dash, why did you say that?" asked Applejack.

"Huh? I didn't say it." said Dash, who was also confused. As they reached the ground and the force field disappeared, they turned around to see who belonged to that voice. They soon saw an unexpected sight. They saw 6 other mares and a dragon looking right back at them. The orange one had on a red bandana and vest with her blonde mane and tail tied back. The lavender one had on a gray coat with an eye patch over one of her eyes and some piercings on her ears and mouth and a horn on her head. The dark pink one looked like she had no eyes and had a flat mane and tail. The yellow mare had on a green sweater and some wings while also having an almost flowing pink mane and tail. The white one also had a horn, but had a diamond shaped hair clip in her purple mane while her tail was curled up. She was also wearing a light purple sweater. A dragon, wearing a black muscle shirt and jeans while also wearing shades, was seen next to the white mare. Finally, the last mare had a cyan color to her body, which was mostly robotic parts. One of her eyes was robotic while the other one, which had a scar over it, had red replacing the white surrounding the magenta eye. What was suppose to be wings was replaced by rockets. The entire left side of this pegasus mare was all machine. But what really stood out from this one was the rainbow mane and tail she had. And when all 14 of them saw each other, the looks on their faces explained it all.

"H-How is this even possible?" asked a very confused Twilight.

"What the hay is going on?" asked the dark pink mare.

"I was about to ask the same thing!" said Pinkie.

"Who are you!?" asked the robot pegasus.

"It can't be..." said Rainbow Dash. All of them then said their next words at the same time.

"You're us!"

The New Threat

"Doctor, we have a problem! It seem the Chaos Emeralds have disappeared!" said a tall yellow robot.

"WHAT!? What do you mean they just disappeared!?" asked the silhouette of a rather large man.

"Take a look for yerself partner!" said another robot with a cube-like body.

"He really needs to get his voice-chip fixed." said a round robot.

"I don't know, I kinda like it." said a robot with a child like voice. The man then took at the screen in front of him and saw that each one of the Chaos Emeralds were no longer on the planet. However, he did see some sort of portal-like thing on the screen.

"Interesting...can we see anything inside this portal?" asked the man.

"We have already done so Doctor. Here's what we saw." said a round gray robot. The screen then showed the image of the 12 ponies and 2 dragons, one of them holding the cyan Chaos Emerald.

"Well now I am really interested." said the man.

"Another thing Doctor, it seems Metal Sonic is also there in that area." said the yellow robot.

"WHAT!? No! I won't let that thing beat me to the Chaos Emeralds if I am to defeat that pesky hedgehog! Now then Decoe, Bocoe, Bokkun, Cubot, Orbot! Prepare my latest creation!" commanded the man, who then got a salute from the 5 robots.

"YES SIR, DOCTOR EGGMAN!" said the robots. Eggman simply smiled afterwards.

"Soon enough, the Chaos Emeralds will be mine and then, the world will be mine! HOHOHOHOHOHOHOHOHOHOHO!!!!!" laughed Eggman. Unknowing to him, a young girl with roses on her head was spying on him and looking at the 14 who were on the screen right now.

"I have to let them know what is going on."

"Okay, this is so weird! How the hay is this happening!?" asked a very confused Rainbow Dash. Apparently her and the others had landed in an Equestria similar to theirs, but the them in this one were much more different. They had gone to this world's Twilight's house to clear some things up. Twilight was busy asking the other her about what was going on, both Rarity's were kind of admiring the cyan emerald they still had as well as fighting over it as well with both Spike's siding with their worlds Rarity, both Fluttershy's were talking about other stuff and the same thing went with the two Applejack's. And this world's Pinkie was trying to calm down a scared regular Pinkie. That only left Rainbow Dash and her robotic counterpart all by themselves. Dash was very confused why this worlds her looked like a robot. She knew that she needed to get answers, so she came up to her other self.

"Uhhhh...hey there." said Dash to her robotic counterpart, who turned around and seemed to glare at her for a minute, but then seemed to calm down and sighed.

"Hi...sorry, I'm just not use to seeing another me here." said robot Dash. She obviously looked just as confused as the real Dash.

"There's something I want to ask you. Why do you look...'different' then me? Hay, what do I even call you? It feels weird to call you 'Rainbow Dash' when I'm Rainbow Dash." said Dash. The robot one sighed a bit and knew that Rainbow should know what had happened to her sometime ago, even if it did seem wrong.

"Okay, I guess it wouldn't hurt to answer those question. First of all, you can call me Rainbot Dash. It's a nickname I got after the incident that made me like this. But we should get everypony together first." said Rainbot, causing Rainbow to nod her head and the 2 rainbow maned pegasi told their friends to gather around. The eyeless Pinkie eventually was finally able to get the real Pinkie to calm down by Pinkie Promising to hold a welcome party and at the sound of the word 'party', the real Pinkie immediately was back to her regular self and was bouncing around until the meeting. As soon as everyone was gathered, this world's Twilight stepped up.

"First of all, I know there's a lot of confusion, but I promise all of you we're going to help you. To start off, since it'll be too confusing to just call us by our real names since there's two of us each, my group will have different names. You can just call me Twi Spark for now." said Twi. Before she can continue, Pinkie suddenly came up.

"Ooh ooh, I know! You can call your Fluttershy Fluts, your Rarity R. Belle, your Applejack AJ, your Dashie Rainbot Dash, your Spike Spines and my other self Pinkamena!" said Pinkie, causing Twi to look bewildered. She looked at Pinkamena, who simply smiled.

"I forgot how random I was before." said Pinkamena, causing the others to simply laugh. After they did, Rainbot stepped us.

"I'll take it from here Twi. Now for the reason me and Pinkamena look they way we do, it happened sometime ago, nearly 2 years now. She invited me to bake cupcakes with her." said Rainbot, causing Rainbow to snicker.

"You? Making cupcakes? BWAHAHAHAHAHA!" Dash suddenly started laughing hard, causing Rainbot's face to get more red then the red in her eye.

"I-it's not that funny! Anyway, I thought it was just an innocent baking session, but then Pinkamena fed me a drugged cupcake. When I woke up, I was in the basement underneath Sugarcube Corner and the corpses of other ponies was the first thing I saw before I saw Pinkamena appear in an outfit made of other ponies cutie marks, horns, and wings." said Rainbot, causing Dash to immediately stop laughing and her and most of the others, including Pinkamena, flinched at the mention of what Rainbot just said. Pinkie suddenly had a sad face.

"B-But I would never kill other ponies, since they're my friend!" said Pinkie as she seemed to be on the verge of having her mane and tail deflating.

"I know Pinkie. But please listen to the whole story." said Pinkamena. Rainbot continued her story.

"Anyway, she then started cutting me up and using my parts to make the very cupcakes I was suppose to help her make. I did die, but one pony resurrected me with these robotic body parts. Fluts was the first pony I saw when I woke back up and she had somehow found out that Pinkamena was possessed by a demon that was making her do all those things. With help from Twi, I was able to free her but at the cost of me having to cut out her eyes. The only reason she can see now is because of a spell Twi learned. That demon was defeated eventually, but I have a feeling that wasn't the only time I'll face it." Rainbot finished her story. The others were speechless. Spike was about to be the first to speak up, but was cut off when he suddenly belched up a letter with the royal seal on it.

"What!? A letter from Princess Celestia?" asked Twilight. Spike took the letter and unrolled it to read it out loud.

"'Dear Twilight Sparkle and friends, I've seemed to have picked up a great energy that has left all of you in another Equestria. This turn of events is very unexpected, but I have confidence that you will find new friends to help you with a new threat...'" Spike read aloud, but stopped there after that last part.

"Another threat!? EEP!" yelled both Fluttershy and Fluts, who then got behind the two Rarity's and stayed their out of fear.

"Anyway, '...This new enemy seems to be after the source of power that lead you to this other Equestria. I fear that the only way to beat this new enemy is with the Elements of Harmony. But you must hurry my faithful student. The longer any of you are away, the weaker the stone seal on Discord will get. And I also fear of another attack from the Changelings. But my most worried concern is the return of Nightmare Moon. You must hurry. Your highness, Princess Celestia.' This is really bad!" said Spike.

"You can say that again." said a new voice. Everyone in the room looked around for the source of the voice. But then new thing they knew, AJ was suddenly blasted with an energy blast and knocked into Applejack, causing both of them to slam into the wall. Then the cyan emerald suddenly disappeared.

"What the hay!? Where did it go!?" asked Twi.

"Finally, I've gotten back the first Chaos Emerald." said the voice again. Everyone looked up and saw some sort of robot creature holding the cyan gem in it's metal hand. The robot looked at the 14 looking at him.

"Even though it won't matter for very long, I'll go ahead and introduce myself. I am your new master, Metal Sonic. And once I have gotten back all 7 Chaos Emeralds, I will conquer this pathetic world!" said Metal Sonic.

"In your dreams tin can! Give that back!" yelled Rainbow as she charged at Metal Sonic.

"Child's play.....Chaos Control!" yelled Metal Sonic before he suddenly disappeared, causing Rainbow to slam into a bookshelf, causing all the books to fall down.

"Really!? I just got those put up there!" said Spines. Metal Sonic then appeared outside the began to fly away.

"He's getting away!" yelled Rainbot before she turned on the rockets on her back and blasted off in pursuit of Metal Sonic. At the point, Rainbow recovered and flew off after the two.

'I'm not going to let that tin can show me up like that! Time to show why I am the one and only Rainbow Dash!' thought Rainbow as she flew up high above the clouds for battle.
