They're Fast, they're blue, they're cocky, they're loyal, and they're coming together. (Wow that was lame, but who cares?)

Rainbow Dash had just engaged in battle with King Sombra in an effort to help free Equestria from his evil grasp as well as help The Cutie Mark Crusaders, she and her friends held their own, however Sombra in a last ditch effort had seperated the Elements of Harmony by sending them through different portals leading to different worlds.

Rainbow Dash had flown through the portal for a while before landing on the other side, in a world strange to her.

"Huh!? Never seen this place before, looks a bit Jungle like" she flew around a bit, looking for signs of life, "Wonder if I'll find anypony around here...I wonder if there's even ponies in this world at all?"

She searched around a bit and then found the strangest thing, "Is that a...blue hedgehog? And is he fighting...robots?"

Indeed Rainbow Dash had spotted Sonic the Hedgehog attempting to liberate a village from control of Dr. Eggman.

Sonic attacked each of the robots with his homing attack, much to Rainbow Dash's amazement.

"Wow that hedgehog has skills!"

The robots fired lasers at Sonic but he dodged them flawlessly and destroyed the robots.

"Man, where's the challenge?" he asked.

One robot tried to sneak up on Sonic with a lance sword but Sonic jumped and back flipped to the other side and then did a sweep kick and then jumped and slammed down with a bounce attack.

"What does Eggman use to build you guys? This is the cheapest metal I've ever seen", at that point Eggman himself attempted to sneak up behind Sonic.

"Look out hedgehog guy!"

"Hedgehog guy?" Sonic turned around and saw Eggman attempt to blast him but he managed to move and hit a homing attack on Eggman, knocking his pod back.

Eggman retreated, "I'll get you next time Hedgehog!"

He flew off with Sonic just watching, "Yeah when my back's turned open season but once I'm ready for a fight just fly away", Sonic sighed, "Typical Eggman, though I do owe some credit to whoever warned me".

Sonic looked around to see if he can find whoever helped him then noticed Rainbow Dash in the sky, "Huh? Is that a Pegasus? That's new"

Rainbow waved at Sonic when he caught glance of her.

"Hey! You the one who warned me?" Sonic asked.

Rainbow nodded and flew up to him, "Yeah, that dude was going in for a sneak attack, I wasn't gonna let that happen"

"Thanks, really owe you one"

Rainbow waved it off, "It's no big deal, though I could use your help with something important"

"Sure thing, what do you need help with?"

"Well this might sound crazy but I'm from another world, or basically another dimension"

Sonic chuckled a bit, "Hey I've been to different worlds and different dimensions before, so I believe you, that would explain you being a Pegasus, not that common in this world, you don't even look Mobian, you don't have hands or feet, you look like an Earth Pony"

Rainbow got confused, "Huh? How can I be an Earth Pony? We just established I'm a Pegasus"

"I know, I meant a pony from Earth, another planet, what did you think I meant?"

"Where I'm from, an Earth Pony is a type of pony that doesn't have wings or horns, they make up for it by being physically stronger though"

"Makes sense', Sonic tapped his chin, then realized, "Wait horns? You have unicorns too?"

"Yeah, don't you?"

"No, those are rare too, I don't think I've ever seen one"

"Wow, I guess I'm one of a kind in this world"

"Nothing wrong with being one of a kind"

"Well I need to find a way back to my world, I don't suppose you can help, you said you're familiar with multi-dimensions"

"I think I can figure something out, might be a bit hard though, but after everything I've done in my time, I think it's very possible, I'll take you back to a village where my friends can help you out"

"Sweet, that would be really helpful"

"No prob, so mind telling me your name?"

"Sure, the name's Rainbow Dash, fastest flyer in Equestria!" Rainbow said while posing.

"Fastest flyer huh? I gotta see that sometime"

"So what's your name hot shot?"

"The name's Sonic, Sonic the Hedgehog, I'm known as the fastest thing alive", Sonic said with a pose of his own.

"Yeah I saw your speed, I'm impressed by that"

"Well I'd like to see your speed"

"Sure, hop on my back and I'll show you", Rainbow said and lowered herself so Sonic can sit.

"Really? You don't mind? I mean I don't think I'm heavy but..."

"It's cool, climb on"

Sonic shrugged, "Alright, if you say so" he got on her back and sat down.

"Where's this village of yours?" Rainbow asked.

"About 20 miles Northeast", Sonic answered.

"Good, Hold on tight", Rainbow said as she got into a starting position.

"Hold on to what?" Sonic said, then Rainbow took off at high speeds in the direction Sonic pointed her to.

Sonic couldn't believe it, she WAS fast, probably as fast as him, he grabbed onto her neck, though made sure not to pull to tight and crush her neck.

They arrived at the location within minutes, Sonic got off, "Whoa that was something, if I weren't so used to running at top speed I would probably be a little dizzy"

Rainbow rubbed her chest, "Thanks, I practice my skills a lot, one day I'm gonna get into The Wonderbolts"

"Wonderbolts? What's that?"

"In my world, The Wonderbolts are a top premiere flying group, the best acrobatic flyers in Equestria"

"That's cool, I bet my friend Tails would like them, he's a flyer too"

Rainbow looked curious, "Tails? Kind of a strange name"

"Well it's his nickname, his real name is Miles Prower, but we all just call him Tails since he has two tails"

"Two tails? How did that happen?"

Sonic shrugged, "No one really knows, some say it's just a birth defect from the pollution that was in this world"

"Wow, so is he a hedgehog like you or..."

Sonic shook his head, "No, he's a fox, all my friends are different species, I'll show you once I introduce you"

Sonic entered the village with Rainbow Dash, several of the citizens not just noticing him, but noticing Rainbow, some even whispered and muttered then Sonic called their attention.

"Sup everyone, this is a new friend, her name is Rainbow Dash, she needs out help so I would like for all of you to be kind and courteous to her"

Everyone waved at Rainbow and she waved back, then did a few poses for the crowd.

"Easy there Dash, don't be a show off...that's my job", Sonic said with a cocky grin.

"Nothing wrong with a little competition", Rainbow said with a cocky grin of her own.

Sonic chuckled and nodded his head, "I guess not"

Soon Sally Acorn had arrived, "Sonic, who is she? Where'd she come from?"

"What no 'Hi Sonic, how you doing'?" Sonic asked, earning a glare from Sally so he decided to simply answer, "Her name is Rainbow Dash, she said she's from another dimension, she needs help getting back to her world"

Sally took a good look at Rainbow, she's not used to seeing Pegusai, "You're from another world?"

Rainbow nodded, "Yeah...is there an issue here or something?"

Sally looked a little displeased at that statement, "Well for one, how did you even get here?"

"I got banished here by an evil King, he did the same to my other friends, except they went to other world, I need to find a way home soon"

Sally took a moment to register that, "An evil King banished you? I hope he really was evil and you're not really a a troublemaker who was banished for any crime you may have committed"

Rainbow got annoyed, "Listen you I'm not gonna just let you say that stuff about-" Rainbow as interrupted when Sonic moved her back a little so he can tell her something privately.

"Hey take it easy Rainbow", Sonic said.

"I'm not gonna let her say crap about me, who does she think she is?"

"Rainbow...that's the princess of this world"

Rainbow felt really awkward now, then turned her attention to Sally, who was standing there with arms crossed and a judgemental face.

"Princess? Wow...awkward"

Sonic nodded, "Yeah...and I know her pretty well and I can safely say that if you annoy her any further...she's probably gonna blow her top and banish you, then you're out of luck"

"Banish me? How? Where to?"

"Don't know, just don't get on her bad side, let her trust you and I guarantee she'll practically be your best friend, she's really nice but years of terror on Eggman left her very cautious about those she doesn't know, a while ago someone in our group had betrayed us, so she's extra cautious around others, especially when it comes to me and Tails"

"Why you and your friend? Any reason?"

"She's kinda my girlfriend...well it's on again-off again, I have commitment issues, and she can't seem to handle that, but she still tries to make it work on occasion, and Tails is like a little brother to her"

Rainbow went wide-eyed, "Your girlfriend's the princess? And you can't commit? That's a sweet deal Sonic, you should commit to that!"

Sonic gave her a 'seriously' look, "I'm not in it cause she's royalty, I'm in it cause I like her, I'd never be shallow enough to date someone just for royalty perks!"

"I still think you're nuts, if someone of royalty liked me I'd definitely commit, well if they're good looking, seems like a sweet deal, and that girl there doesn't seem bad looking, why not just stick with her?"

Sally groaned, "I can hear what you're both saying! Rainbow pony, I would appreciate it if you didn't delve into my personal love life, and Sonic, get over here before you blurt out something stupid!"

Both Sonic and Rainbow Dash groaned as they walked back to Sally.

"Now then, as Sonic told you Rainbow Pony-"

"My name is Rainbow Dash", Rainbow put plainly.

Sally growled a bit, "Ok...Rainbow Dash, as Sonic told you I am the Princess of this world, now I'm not really one to brag about my title but I do demand some degree of respect, both from my people and from outsiders in my world, now if you're story is true and you were banished here by an evil king then I suppose with some of our resources we can locate your dimension and get you back home, until then you're gonna need a place to stay so Sonic..."

Sonic did the gun point with the click noise, "Sally?"

Sally was not amused but she continued, "I'm gonna task you to keep an eye on Rainbow Dash, don't let her out of your sight, she will be bunking with you"

Sonic grinned, "You won't get jealous of a pretty girl staying at my place?"

Rainbow blushed a bit at the pretty girl comment, though she turned her head so no one would see it.

"If you use the term 'pretty girl' loosely then don't worry, I won't be jealous"

Rainbow looked annoyed and got in Sally's face, "You trying to say something to me Princess?"

Sally wasn't intimidated, "Get out of my face before I break yours"

Sonic got in between the two, "Girls, come on, can't we just get along?" Sonic chuckled nervously as Sally and Rainbow turned away from each other.

Sonic sighed, he was gonna have his hands full with this.

That's the start, soon Rainbow Dash will meet the rest of Sonic's friends, including his best friend Tails, how will the rest of them react to Rainbow Dash?
