I'm finally ready, guys. I've been looking for the source material online for months, and I finally found it. I know what you're thinking; "Why didn't you just wait until the movie came out and then looked?" Well, what can I say? The meaning of the phrase "Patience is a virtue" seems to be lost on this generation. Either way, let's get right into it. And just so you know, any text inside parentheses is me, the author talking. Okay, let's go.

When an evil unicorn with a broken horn arrives and takes over Canterlot, Twilight Sparkle and her friends must journey south to the Badlands outside of Equestria to find help from some unusual creatures. Hopefully, it will help to have a hero from another dimension there. That hero, of course, is Sonic the Hedgehog.

Now really quick, a little rundown on the Sonic I'm using here: The design is a more realistic sort of Sonic created by EvanStanley, and I'm making him an absolute badass. Through his career of jumping across the Multiverse as a superhero, he's had plenty of opportunities to train under some of the best combatants in gaming, comic and anime history. In addition to his usual martial art of incorporating high-speed spinning into karate, he's learned Kame-Sennin Ryu from Son Goku in the "Dragon Ball" universe, Goken's variation of the Ansatsuken fighting style from Ryu in the "Street Fighter" universe, the Santoryu Three-Sword style from Roronoa Zoro in the "One Piece" universe, and of course he's learned how to channel the Speed Force thanks to training under the Flash and Quicksilver (I know Quicksilver can't use the Speed Force in canon, but it just makes it a lot easier to say every speedster in the Multiverse shares the same power source). So he's basically unstoppable. Especially when he gets his hands on all seven Chaos Emeralds, which will be in this story.

Speaking of which, let's just get on with it, shall we?

Insert "Monty Python and the Holy Grail" scene here.

Bridgekeeper: Get on with it!

Tim the Enchanter: Yes! Get on with it!

Huge Army: GET ON WITH IT!

Well, I guess a little more exposition wouldn't hurt.

God: GET ON WITH IT!

Okay, okay, fine. Sheesh. There's just no pleasing some people, huh?

Ch. 1: The Hero of Another World

Another beautiful, friend-filled day in the world of Equestria. As one can expect, especially when you live in the capital city of Canterlot, as today was the day of Princess Twilight Sparkle's first ever Friendship Festival. And her assistant, Spike the Dragon of course, who was racing through town with a load of scrolls in his arms as he landed on a blob of gelatin.

"'Scuse me!" he said as he ran through the crowd. "Dragon on the move! Important princess documents comin' through!"

"Whoa!" said an Earth Pony filly. "Everypony from Manehattan to Saddle Arabia is here!"

"I know, filly!" said her friend. "We almost couldn't book a stable!"

"Princess Twilight must have her hooves full with this giant festival," said a Pegasus mare as she and her friend flew past the castle.

"Are you kidding?" asked her friend. "She's smart and organized and cool under pressure. There's nothing she can't handle!" Well, all I can say about that Pegasus' comment is that it was partially true. Princess Twilight is smart and organized, but cool under pressure? Pfft. Extremely rare occurrence to say the least. When she starts rattling off worst-case scenarios, you're not gonna get a word in for at least thirty minutes. And that's if you're lucky. This is behavior we will now observe, as we slip through her plate-glass window in the castle hallway up to the throne room.

"Ommmmm…" she said to herself. (Huh. That's funny. Guess this is one of those rare occurrences). "Ohhh, mmmy goodness! I can't handle this!" (Ah nope, there we go). "Ooh! Nothing is working! I just have to keep it together. Just go in there. And ask. This is your Friendship Festival. Everypony's happiness rests in your hooves." Then she just smacked her face with her hoof and groaned as Spike ran in.

"Okay, Twilight," he said, showing her the charts in his arms. "Got all your charts and graphs."

"Oh, thank goodness you're here Spike!" said Twilight. "I'm just so nervous about this meeting."

"Whatchoo talkin' 'bout?" the dragon asked in a gangster tone.

Twilight sighed. "I'm about to ask the three most royal princesses of Equestria for a huge favor," she said. "What if they reject me?"

"It'll be fine," said Spike reassuringly. "Just remember the most important thing."

"Smile?!" asked Twilight nervously, giving a huge toothy smile that obviously creeped Spike out. Either that or the twitch under her eye, but the jury's still out.

"Eh… no," he said. "You're a princess too."

"Right!" said Twilight in a tone that I still cannot place. I'm pretty sure it's that one when you give a wrong answer to the class and get called out for it but don't want to sound angry or anything like that, but the jury's out on that one too. Anyway, back to the story. Twilight let out a deep exhale as she opened the doors to the throne room and was welcomed by the warm smiles of Princesses Celestia, Luna, and Cadence. "Good morning, princesses. Thank you all for seeing me. I have an idea that I think will make our Friendship Festival the most wonderful celebration Equestria has ever seen."

"Yes, Twilight," said Celestia happily. "We are very excited."

"Ponies have been arriving from all over all morning," said Cadence as she glanced out the window.

"I'd like to think it was to see us," said Luna before she chuckled. "But Songbird Serenade might be the bigger attraction."

"Yes, she is the 'mane' event," she said before giggling. (God, I hate puns). "And to make it extra special, I could use your help. Spike?" Spike then wheeled a whiteboard over and hummed a fanfare.

Just then, before Twilight could say anything else, a soldier of the Royal Guard entered. Cadence recognized him almost instantly.

"Knight Watch?" she asked. "What's going on?"

"Forgive the intrusion, Princess Cadence, but I've come with rather dire news," said the guard.

"What's wrong?" asked Twilight. "Songbird Serenade didn't cancel already, did she?"

"No, your Highness," said Knight Watch. "The Guards have captured an intruder in the city, but we're not sure what to make of it. We don't even know what it is."

"I resent being called 'it', just so you know, ya jackass!" called a male voice from beyond the door. Then they heard a donkey bray also outside. "Ooh, no offense, dude."

"None taken," said another voice.

"Anyway, we brought him here so that you might be able to give us some sort of idea," said Knight Watch. "Bring in the prisoner." Then two Pegasus guards walked in pulling some sort of creature in chains. Whatever he was, he had blue fur all over his body except on his chest, arms, muzzle and inside his large ears, which was tan, evident collarbones and ribs in his chest, long limber legs with feet encased in bright red soapbox shoes with white straps held down by gold buckles, along with small green lights in his heels. On his hands were large white gloves with the cuffs rolled up to his wrists. On his back and the back of his head were large spikes, and he had a small black nose and bright emerald green eyes. Celestia, Luna, Cadence, and Spike were a bit frightened, but Twilight was just fascinated.

"What in Equestria are you?" she asked.

"Equestria? So that's what this universe is called," said the creature. "Good to know. Now I'd be more than happy to inform you of who I am and where I'm from as long as your guards let me go. Seriously, these chains are actually surprisingly itchy."

"Well, you heard him, Knight Watch," said Twilight. "Release him."

"Trust me, your Highness, I would, but we found him wearing this belt," he said, levitating a belt out from behind him. "We're unsure of what these are, but we believe they might be weapons."

"You guys seriously do not understand Multiverse Theory or science, do you?" asked Sonic.

"No, we have Multiverse Theory, but we've just never seen items like these before," said Celestia as she levitated Sonic's belt in front of her.

"Okay, good to know," said the creature. "Now if you'll excuse me, I'll just liberate myself from these chains and I'll be more than happy to tell you everything."

"And how exactly do you hope to do that?" asked Knight Watch.

"With this," said the being as he closed his right hand into a fist, and then when he opened it, a large blue gem was revealed in it. "Chaos Control!" Then in a bright flash of blue light, the being disappeared and reappeared in front of Celestia, taking his belt back and snapping it around his waist. Then he slipped the gem into the spikes on his head. Everyone was amazed.

"How did you do that?" asked Celestia.

"That, my lady, is the power of the Chaos Emerald," said the creature as he pulled the gem back out of his spikes. "There are seven of these jewels in total, each one a different color, and each one containing the power of the cosmos. When all seven are gathered together in one place, one of two things can happen. Either A: When used by someone with an evil heart, they could bring about the apocalypse. Or B: When used by someone with a pure heart, i.e. me, they empower that individual with enough energy for them to be comparable to Gods."

"And alone, they can let someone teleport?" asked Cadence.

"Well, technically it's not real teleportation," said the being. "I just use this thing to warp the space-time continuum to slow down time and warp myself to another location. Plus, when I use its power, I can enhance my speed, shoot frickin' lasers out of my hands and endure the cold, unforgiving vacuum of space." Then he put the gem away. "But enough about these things, let's get to introductions. Sonic at your service. Superhero, warrior, interuniversal traveler, hedgehog of many talents."

"You're a hedgehog?" asked Luna, confused.

"Mobian, to be precise," said Sonic. "Back in my universe, standard animals like hedgehogs, bats, and foxes have evolved into humanoids, with clothing and insane superpowers."

"Powers? Like what?" asked Spike.

"How bout you ask those guys?" asked Sonic, pointing to the two guards who pulled him in, who looked completely exhausted. "And in case it wasn't obvious, my mother didn't name me Sonic for nothing." Then he zipped out of the room so fast, he just appeared as a cobalt blue blur and sent a huge shockwave echoing through the castle, then he zipped back and stopped with a loud tire-like screech with an ice cream in his hand.

"Whoa! And here I thought Rainbow Dash was the fastest in Equestria," said Spike.

"You would think that, but then again, when you knew her… Rainbow Dash is a her, right?" asked Sonic, to which Twilight nodded. "Okay cool, you did not know I, or my universe, existed."

"You make a fair point," said Twilight. "So then how did you get here?" Sonic scratched the back of his head.

"I'm actually kinda trying to piece that together myself," he said. "Last thing I remember is that I was helping my friend Tails with testing a prototype interdimensional teleporter, I push the wrong button and ba-Boom-ba! Next thing ya know, I'm in a back-alley downtown and there's a bunch of ponies setting up for some sort of fiesta. What's the deal with that anyway?"

"That's my new Friendship Festival," said Twilight. "My friends and I have been planning it for months, and we're finally putting it into action. Oh, by the way, we never did introduce ourselves. I'm Princess Twilight Sparkle, Princess of Friendship. This is my assistant Spike, and these are my fellow princesses; Celestia of the Sun, Luna of the Moon and Cadence of Love."

"Well, nice to meet you all, but if I'm interrupting something, I can easily leave," said Sonic.

"No, please," said Celestia kindly. "I insist. Stay."

"Alright then," said Sonic as he leaned against the wall near a window.

"Now then Twilight," said Luna. "Your plan?"

"Huh? Oh yes, of course," said Twilight, levitating a dry-erase marker to the board and started drawing. "Songbird Serenade's performance is not scheduled to start until after you begin the sunset. And based on my precise calculation, to get the very best lighting for the stage, Princess Celestia, I was hoping you could make sure the sun stays about 28.1º to the south, and, Princess Luna, if you could raise the moon 62º to the north at the same time, it would reflect the sunlight on the other side and really frame the entire stage perfectly!"

"I-" started Luna.

"But wait! There's more!" said Twilight as she continued drawing. "Cadence, if you could use your crystal magic to create an aurora above the stage, the sun and the moon will shine through it and create a truly amazing light show!" Then Spike threw a claw-full of sparkles above the board.

"Introducing…" he said, jumping up to the top of the board with a cut-out of the famous pony pop-star. "Songbird Serenade!" Then he started singing before he lost his balance and fell off. "Ta-da…" he said weakly. Twilight quickly opened her wings to try and hide him from view as she gave a nervous grin. Sonic and the other princesses just stared at the board.

"I'm sorry, what?" asked Sonic, obviously confused.

"So you're saying you want us to move the sun and the moon for the party," said Luna.

"Well, I'd do it myself, except I don't have your magic," said Twilight and she gave a cute snort.

"Can't they just give you their power for the day or something?" asked Sonic.

"Already did that once," said Spike. "And that was an insane emergency."

"Oh okay," said Sonic.

"Twilight, each of us uses our powers to serve Equestria in our own way," said Celestia as she and the other princesses activated their magic around their horns. "You are the Princess of Friendship. You already have all the magic you need."

"So… that'd be a no?" asked Twilight
