From Mobius to Equestria

Sonic

Sonic, Shadow and Silver were in the middle of a fight against Dr. Ivo Robotnik, AKA Eggman. Eggman had already collected all seven of the Chaos Emeralds, and was using them as a power source for a “Space Bridge” which could be used to cross dimensions. If Eggman used this portal he could wreak unlimited amounts of havoc throughout the Dimensional Plane. So the three hedgehogs were here to shut it down.

After a long battle with Badniks they eventually reached the engine room of the Space Bridge. Eggman had already activated the portal but it takes time to artificially punch holes in dimensions. Before the portal could form completely, Sonic Dashed through the power cell, which had unfortunately charged enough of the energy from the Chaos Emeralds to cause a small scale explosion. The bridge was operational before the explosion and the portal sent Eggman, Silver, Shadow and Sonic, along with the Chaos Emeralds to an entirely different world.

Rainbow Dash

Rainbow Dash was sunbathing on a cloud above the library in Ponyville. Below her she knew that her friend Twilight Sparkle was doing some form of research as usual. She heard an explosion from the Everfree Forest, just past Fluttershy’s cottage. When she turned her head to the sound, she saw four figures, along with seven Rock-Like things dropping right out of the sky.

Being the fastest thing in Equestria, she could check out what fell and be back in five minutes. Rainbow jumped off the cloud and flew five miles before landing and running the rest of the way without losing momentum. She found the spot where one of the objects landed and skidded to a stop at the edge of a crater. What she found was the oddest creature that she had seen in her life. And in a place that’s crawling with Dragons, Hydras and Manticores, that’s saying a lot. The first thing Rainbow thought she should do was bring this thing to Fluttershy’s. She was, after all, an Animal Caretaker.

Sonic

Sonic woke up in a small cottage, like one you’d find in old stories. The bed he was laying on was a little long for him, but it was comfortable. He looked around and found a lot of animals in the house with him. He heard voices coming from the other room, talking about a “strange creature” one of them found.

“Rainbow Dash, I don’t think I can do much for him,” One of them said. It was a girl, maybe as old as he was, but he wasn’t sure.

“Just make sure it doesn’t wake up hostile, Fluttershy,” The other said, it was a girl too, maybe that was Rainbow Dash? “I gotta go find the other things, and see if they’re Alright, if they’re anything like this thing.”

Sonic realized that they were most likely talking about him and the others. He sat up and felt nauseated. The room started spinning, almost like he had a Drink, but he knew he had to be Sober, because he didn’t drink anything since he got… wherever he was. And he never had that kind of Drink in his life. He did hear the door close, and the voice, Fluttershy came into the room.

“Oh! You’re awake, little guy!” He looked to the voice, and saw… a yellow horse… with wings… and a long head of light pink mane. “You must be very dizzy after crashing into the ground like that. Are you alright?”

Sonic let out a yelp at seeing a Talking Pegasus right in front of him.

“You Okay?” she asked.

“You’re… talking!” Sonic yelled. At this, Fluttershy started to look amazed, and smiled.

“Wow you can talk! Just what are you? I’ve never seen anything like you before.”

“I’m Sonic, Sonic the Hedgehog.”

“Well, Sonic, I’m Fluttershy, Animal Caretaker of Ponyville.”

“How did I get here?”

“You were unconscious from falling out of the sky, and Rainbow Dash brought you here to see if I could help. She’s out looking for everything else that fell with you.”

For the record I wrote this a while ago... I just had to share, I know I said i wouldn't put anything out anymore... but things came up and i decided to take another shot at it.

Fear for the First Time

Rainbow Dash

Rainbow went back to the Everfree Forest to look for… whatever came crashing down with that other thing. She found three other craters, one bigger than the others, but there was nothing in any of them. Before she could leave the Forest, she found herself so much further in than she ever went in her life. Normally, in circumstances like these, she’d gain some altitude and find her way back from there, but another thing about being a Pegasus, is you can feel the air current stability above you, and it was too violent for flight since those things fell.

Even this far in, Rainbow knew that her friend Zecora the Zebra’s place was not too far away. If Applebloom was there she would be in luck. Applebloom was the only pony besides Zecora (If you count her as a pony) who could navigate the Everfree Forest like a Professional. Suddenly, seemingly out of nowhere, Rainbow was attacked by Basilisks, serpent-like creatures with limbs and frills on the side of the face that turned anything that looked at the wrong moment to stone. There were five of them that she could see, but it was so dark in the forest she couldn’t tell how many there actually were. They had her cornered against the side of a cliff one moment, and the last thing she saw of them, they were ganging up on her.

Sonic

Sonic ran into the forest, to look for Rainbow Dash or whoever it was who saved him. He heard her voice from the south, in a very loud shout for help. Following her voice he saw another Pegasus, this one with blue fur and rainbow mane, cornered against a cliff by… what looked like Hybrid Snake/Lizard things. Before they could tear her apart, Sonic Dashed a way through to the front, knocking… Whatever they were out of the way.

Sonic charged whatever Dash Power he could, and shot through the rest of them, either in spin dash, or just head first. There were enough of those things that, by the time he got through the last one and skidded to a stop in front of the horse, he was lightly panting. Then there was a movement from the cliff. What came over the side was the first thing EVER to paralyze Sonic with fear.

Rainbow Dash

Rainbow Dash looked up at what the blue thing was scared of. It looked like Spike did when he grew up that one time and nearly brought Ponyville to the ground. The only difference was this thing was made entirely of stone, with eyes that glowed white… all six of them. Rainbow couldn’t bring herself to assure the blue thing that it was going to be okay; she wasn’t as kind as Fluttershy, or as honest as Applejack. Loyalty couldn’t do anything here; she just looked up at the golem, afraid for her life for the first time ever.

Then she heard a deep voice say something she didn’t understand, not like Zecora’s Nursery Rhymes from her home, more like one of Twilight’s Explanations.

“Chaos… Control!” a black form shot right up into the Golem’s Face Knocking it back a few miles. Then the form landed in front of her, and the other thing. The blue creature looked more relived at this than she felt, mostly because this thing was shaped very closely to the Blue thing.

“Shadow!” the blue one said.

“Sorry I’m late, Sonic,” Shadow said. “Ready to double team this thing?”

“As ever!” Sonic said. They grabbed each other’s hand and shot themselves right for the head of the monster. It was in this confusion, that Rainbow saw a small chip missing from the chest of the creature. She found herself backing up far enough to run up and use the Buccaneer Blaze on this weak point. With contact the creature fell apart. And they all landed at the top of the Cliff. mal>

There's gonna be some serious editing I swear. please keep in mind that this is one of my first Fanfics and at the time I wrote this I was very new to writing stories in general

Where in the World ARE WE!?

Sonic

Rainbow Dash had a lot of questions for Sonic and Shadow. Shadow was quiet for the entire trip to the nearest house. Sonic tried to answer all of Rainbow’s questions, but he wasn’t Tails, he didn’t know how he got here, where he was, or even if they could go back to Mobius like this. Turns out they could find the nearest house was in the woods, and it belonged to… a Zebra… a Zebra with the profession… of a Witch Doctor.

“Zecora?” Rainbow Dash asked. “Is Applebloom here?”

The Zebra, Zecora was standing in front of someone. She turned to look at her guests, only when she was done slathering an ointment of some sort on them.

“I’m right here!” the… patient said. Zecora stepped aside revealing a filly with yellow fur and red mane, with a pink bow. There was a slight difference between Rainbow Dash and Fluttershy, and this little thing… Applebloom was missing wings.

“What happened?” Rainbow asked.

“She sprained her ankle running from the Colossus,” Zecora said. “I am amazed of what happened that saved us.”

Sonic looked at Shadow to make sure he wasn’t seeing things. Shadow staring with a look of half as much astonishment as Sonic had… that’s the only way to know that he actually felt more astonished at this. A Zebra was talking to horses in Rhyme, and they completely understood what they were saying!

“Are we… sane?” Sonic asked Shadow.

“If you see a blue Pegasus with a rainbow haircut, a yellow horse kid with a pink bow, and a zebra all talking in a language we understand…” Shadow said. “Yeah we’re sane.”

Zecora and Applebloom noticed them just as Shadow said the word “sane.”

“Um, Rainbow Dash?” Applebloom started. “Who… and what are those… things with you?”

“I’m… Sonic the Hedgehog,” he was regaining some of his calm by now.

“I’m Shadow… the Hedgehog,” Shadow was still having a little trouble… but he was getting there.

“You don’t look like any hedgehog I’ve ever seen.” Zecora stated. “Would you care to explain just where your kind has been?”

“I said this to Rainbow Dash, I don’t know. But we were the only South Islanders who came through the Portal here, if you don’t count Silver.”

Rainbow Dash

“South Island?” Rainbow asked.

“On Mobius, the planet we’re from, there are four Islands with Creatures who are as intelligent as the dominant species, if not more,” Shadow Explained. “We come from the southern most of these Islands where only the Herbivores and Insectivores are anything near that smart. Anything from these Islands also happens to have extraordinary abilities that others don’t have.”

“Okay, now I’m even more confused,” Rainbow said. All she ever knew as a dominant force in Equestria was magic and even that confused her. This kind of explanation was beyond her comprehension.

“Maybe we should find a translator. I think I’m as lost as you, and I came here with him!”

Translator… for eggheads… one pony came to mind for Rainbow.

“Twilight.”

“What?” Sonic asked.

“Twilight’s a friend of mine, the smartest pony I know. She might be able to explain what kind of Magic brought you here.”

Sonic and Shadow just stared at her. Almost like they didn’t know what magic was. Rainbow just ignored that much, though she wondered what it was about. She asked Applebloom if she could walk, and decided to tell Applejack that she’d be home a little later.

Sonic

“Okay, let’s go see Twilight!” Rainbow Dash said. Sonic was still confused about what Rainbow said about Magic being what brought them here. But he knew better than to question that, he had gone to other places where there were forms of mysticism that couldn’t be explained.

Rainbow decided to live up to her name at that moment, and Dashed out of the forest while hovering five feet off the ground. This got Sonic’s attention.

“See ya’ on the other side, Shadow,” Sonic just ran after Rainbow, eventually catching up to her.

“What!? How did you…!?” Rainbow started, but never finished. Before she could say what else was on her mind they were back in Ponyville, and they ran into a tree. They got up a little dizzy, but they weren’t hurt too badly.

“Wow… that was fast,” Shadow said. As Sonic expected, He used Chaos Control to bring himself closer to Twilight’s house. As if the talking horses weren’t enough, turns out Twilight’s house happened to be the tree they ran into.

“How did YOU beat us!?” Rainbow asked. “I never even saw you run!”

“That’s Chaos Control for ya’,” Sonic said. “It’s basically the ability to slow down Time and bend Space.” Now Rainbow looked even more confused. And that was the first time Sonic ever heard Shadow laugh, even though it was ever so slightly.

Author's Note

Here goes... everything.

Canterlot's Peril

Rainbow Dash

Twilight came out of the Library at the sound of Shadow laughing. She looked more perplexed at this than she did when… you know, Rainbow never saw her perplexed. The only ones more confused at what they were seeing were Sonic and Shadow. I guess it couldn’t be helped since they weren’t use to talking ponies.

“There’s… more of these things?” Twilight asked no-pony in particular.

“More? Does that mean Silver’s here!?” Shadow asked. Speak of the Nightmare, a White hedgehog walked out the door at the mention of the name “Silver.”

“Yeah, I’m here,” he said rolling his shoulder. “I’m still a little sore from that Bad Fall I had, but I’ll be alright.”

“Okay Rainbow Dash,” Twilight said. “Just what are these things?”

“I’d say mutant hedgehogs but this seems to be completely natural where they’re from.”

“Actually, you could call me a mutant,” Shadow said. “I was artificially given the power I have now.”

It seemed like Twilight was going to ask what he meant by that, but Spike had to interrupt.

“Twilight! You’ve got a message from Princess Celestia!” he said. “It’s a Distress call!”

Sonic

According to the Distress Call that this “Celestia” sent, a monster was attacking a city called “Canterlot.” Twilight called the Spirits of Harmony to the library. There was Applejack, Spirit of Honesty, Fluttershy, Spirit of Kindness, Rarity, Spirit of Generosity, Pinkie Pie, Spirit of Laughter and Rainbow Dash, Spirit of Loyalty. Twilight told them about the situation. Sonic turned to ask Silver and Shadow if they should help… but they were already gone.

“Hey where’d they-“ Sonic looked back to find Rainbow Dash was the only one still in the room.

“They all went to Canterlot already,” Rainbow said.

“Why’d you stay behind?”

“I want to see how fast you are, and I could reach Canterlot in five minutes without teleporting.”

Sonic got where this was going, and he liked the idea.

“Alright then, let’s go!”

Rainbow Dash

Rainbow kept her promise and was at Canterlot Five minutes later. Funny thing, so was Sonic. What she saw off in the distance was horrendous. It looked like a Gorilla grew a turtle’s shell with spikes and an extra set of arms.

“Sonic!” Shadow came down from the side of the gate. “I’m sensing a large amount of Chaos Power from that thing!”

“Chaos… Power…? Like Discord?” Rainbow asked.

“No, it’s worse! I use this power for Chaos Control!” Shadow simplified.

“Does that mean it has the Chaos Emeralds!?” Sonic exclaimed. Shadow nodded and Sonic dashed into the distance to do Celestia knows what. So she dashed after him to try and help however she could. When she got there, Sonic was just looking at the thing from over a cliff as something started laughing maniacally. Then it came down on something shaped like an egg. It was another weird creature, not like sonic and the others.

“Well Sonic, seems you’ve found your way to this World too.” It said.

Sonic looked at this thing with some form of amusement. And said the weirdest thing she ever heard.

“Eggman!”

The Werehog Returns

Sonic

Sonic knew one thing for certain. For someone with an IQ of three hundred, Eggman makes the worst creations, whether they’re mechanical or organic in origin. If he was the one responsible for the existence of this… thing, Sonic would have no problem beating it, especially if he could get in close enough to channel the power of the Chaos Emeralds… but Rainbow was in the field as well, and if there’s one thing he couldn’t do, it was leave the innocent to the hands of fate in this situation.

During Sonic’s moment of hesitation the monster had somehow grabbed Rainbow Dash before she could get away. Sonic snapped out of his trance and ran, purposefully getting grabbed by the monster.

“Wow Eggman,” he said. “This is too easy!” Sonic closed his eyes and focused on the Power of Chaos. The Chaos Emeralds just popped out of nowhere. Then Sonic absorbed them as he had done hundreds of times before, and turned into Super Sonic. The explosion of power tore apart the arm of the monster that was holding him. Sonic started flying around the monster, chasing Eggman after he got Rainbow to safety.

Rainbow Dash

Rainbow Dash was astonished. She never saw anything as awesome as Super Sonic. Right now he was the one living up to HER “twenty percent cooler” thing. Then she saw Eggman push a button and something came out of the woods and knocked Sonic down. Then it started to drain whatever power Super Sonic had.

While that thing was draining Sonic of the Chaos Power, Rainbow got a good look at its face. Or should I say “his.” This thing was the more artificial form of a Chimera. Every kind of creature that could be described here could describe this thing.

“Discord!” Rainbow said. Discord turned to Rainbow.

“Rainbow Dash,” Discord said. “You really want to fight me now? Especially considering I have another creature under my power?”

Rainbow knew he had a point, but she wasn’t about to leave Sonic in this kind of agony. Princesses Celestia and Luna had already brought the night around, so she couldn’t really see much of what was happening to Sonic. Finally whatever Discord was doing was over, and he came down to see his new minion.

“Well, it seems I have already made myself your master,” Discord said. Then right where Sonic used to be, a huge fist just popped out and forced Discord into the monster that Eggman was using.

“I have no master!” Sonic said… at least it sounded like Sonic, but it was more ferocious.

Sonic

Sonic recognized what happened to him. It happened before, when Eggman broke Mobius to pieces and Dark Gaia was released. Because Sonic was in Super form when he was being used to power the laser, he got a nightly taste of Dark Gaia’s power and Became Sonic the Werehog every night. This was that form.

Sonic got up and revealed to Rainbow what he had become. The look on Eggman’s face was priceless. Before Eggman or discord could do anything, Sonic used his stretchable arm and grabbed the monster. He threw it over his head like a professional wrestler. Then he brought his arms forward and grabbed Discord and the Eggmobile. He threw them around for five minutes and then he forced them into the ground.

Somehow, when Sonic retracted his arms, Eggman and Discord were gone. Sonic looked to the heavens and remembered the month he spent with Chip in fondness. The fact that Chip turned out to be Light Gaia made the end of that adventure more… depressing. For Chip’s sake Sonic let out a howl that he never thought he’d use again.

“Sonic…?” Rainbow said coming up behind him.

“It’s alright Rainbow,” Sonic said. “I’m still me.”
