I've seen this idea done before, but as a fan of Sonic and MLP: FiM, I wanted to give it a go myself.

This, basically, is the story of Sonic Generations, but crossed over with the MLP:FiM universe, with Spike and the Main Six taking the place of Classic Sonic and Classic Tails with other MLP characters also appearing (most aren't listed to prevent spoilers). Except for Green Hill, there will be different areas explored, as well as pony rivals and different era bosses. So while it will have its similarities to the console and 3DS versions of the actual game, it will definitely have its differences too.

Also, in case anyone was wondering, there will NOT be any shipping in this story. At the very least, no crossover shippings. No SonicxRD, TailsxTwilight, TailsxFluttershy, or anything like that. If there is any shipping at all, it will only be between characters from the same universe. And the only humans in this story are Dr. Eggman and the ones that appear in the "Sonic Unleashed" level.

A big thanks goes to bvge on Deviantart for creating the new logo on the cover art. It's a vast improvement over the old cover art.

The TV Tropes page can be found here.

NOTE: Due to the length of many of the chapters in this story, most of them have been broken up into smaller parts of roughly 10,000 words or less to make the story easier to read.

Hey everyone! I know this particular crossover isn't very popular, considering what I've seen on the few others on this site. However, I've had an idea like this for a while now and I want to know if I can do a good StHxMLP:FiM crossover or if I'm doomed to end up in that same pit of failure.

Anyway, this chapter is just the intro, setting things up. The event that Twilight and Spike talk about will be referenced again later on. And I know about the whole issue with Derpy, but as long as there's a version of "The Last Roundup" with the original scene out there, like in "The Friendship Express" DVD, I'm going to go with that instead of the altered version. If there are any complaints, I can change her name, but I still want her to be in this story.

I think that's about it. I'm interested in hearing what you think, as long as it's meaningful.

Before I read this, may I just say that your image could use a lot of work. It's like whoever made it didn't even attempt to make it look good; even MS Paint lets you paste things without having that kind of artifacting.

All right, it seems like a pretty okay story so far. I look forward to seeing where you go with this.

Can I use the Sonic part for one of my stories? It's really good.

Really good so far, hope you write next chapter soon.


Okay, I admit that was a rough attempt on my part to create a cover image. But I did my research after I saw your comment and I gave it another shot. I hope it looks better now.


Yeah, go ahead. I don't have a problem with that.


Yes, that looks much better. I'd personally use a different font for the subtitle, with possibly a border, but it looks fine in its current state.

Mm, I don't know about this one. I think it's a good chapter, but I'm not sure how I feel about it. It just... I don't know.

Anyway, I think the song "Metropolis Zone Vs. Pinkie Pie's Pinkie Party" might be a good remix to listen to for this chapter: http://www.youtube.com/watch?v=TpuYom4KM30

It looks good. I wonder what is going to be next. :eeyup:

Great job, I wonder who you'll pair up with next ? :pinkiehappy:

Please do keep up the good work upon such a great storyline like this one. :rainbowkiss:

I'm terribly sorry about the long wait for this chapter, everybody. Most of my classes last week had exams, so I had to spend some time studying for them. Not to mention this turned out to be a long chapter. I hope the length makes up for how late it is.

Now, a few notes for this chapter. The radar that Tails builds looks basically like a Nintendo 3DS. I got the idea from Issue 219 of the Archie StH series, which featured a "Sonic Colors" adaptation. In the adaptation, the device Tails used to translate what Yacker was saying looks nothing like his Miles Electronic from the games.

The numbers that Tails' radar displays are the original North American release dates for Sonic 1, 2, and 3.

The move Sonic and Tails perform to escape the ice cave is the Rolling Combo from the upcoming "Sonic 4: Episode 2".

Sonic's explanation for his shoes is based off of "Adventures of Sonic the Hedgehog". AoStH described them as friction-proof and joked that Sonic will burn his feet if he tries to run without them.

I think the following Ice Cap remix would be great for this chapter: http://www.youtube.com/watch?v=efq_35xi53M

Okay, that's about it from me. Next chapter will feature the first rivals!

So far, so good.

I have a suggestion: when it comes time for Shadow the Hedghog to appear, have him working with Gilda the Griffin, like Rainbow Dash is with Sonic. It be two vs. two. Four types of speed/cool. You get what I mean? =3


Hm, yeah, I get what you mean. It's just... I was planning on bringing in Gilda in the next chapter.


**Acts like Chris Pine** "DO IT! DO IT! DO IT!!!"

Uh, sorry about the wait for this chapter. Aside from the Metal Sonic battle, I'm worried that I didn't get Scootaloo and Gilda right. I hope they turned out okay.

So... notes. Gilda having the Element of Loyalty is meant to be a reference to an AU fanfic I read where Gilda is the Element of Loyalty instead of Rainbow Dash.

Tails facing off against Metal Sonic in Stardust Speedway is a reference to his inclusion as a playable character in the digital re-release of "Sonic CD".

If there's anything else that catches your eye, feel free to mention it.

This story is awesome!!:pinkiehappy:
But why does it have 9 thumbs-down?:fluttershysad:
This deserves more thumbs-up than down ones. I already favorite, liked, and tracked this fanfic.
This has got to be the most epic Sonic and MLP crossover story I have ever read.:pinkiesmile:

Great song choices for the story.

Although, from the title, I was hoping Sonic and Rainbow Dash would race both Metal Sonic and Gilda together like a tag-team race or 2 vs. 2 or something. But this works out well, cause it shows that this story just ain't just about Sonic & RD kicking ass/flank, it's everybody/everypony fighting for what's right and restoring both their worlds to normal together as one complete team. :rainbowdetermined2:

If I may ask a question: If this were an actual anime OVA, what japanese opening & closing themes would you give this? The Sonic X japanese themes, or something esle that has that "racing beat"? I can imagion a TV Sized version of "Super Sonic Racing" being a closing theme.

Anywho, I also have another question: Well we be seeing the Daimond Dogs, Trixie, Photo Finish, and Prince Blueblood as villians in this story like Gilda was, like as future bosses?

Anyways, keep up the good work. I've been a fan of Sonic for a long time, and never seen a good Sonic/MLP crossover as good as this one. There was one or two on Fanfiction.net that were interesting, but I quickly lost interest. But this keeps me going. After watching the walkthrough of the Sonic Generations game (I have only a SuperNES & PS2), I would love to see how this crossover plays differently from the offical game story.

Til next chapter. :pinkiehappy:


An anime opening and closing theme, huh? Well... I guess the Japanese opening "Sonic Drive" would work as the opening and either "Cosmic Eternity" or a TV-sized version of "Super Sonic Racing" would make a good closing theme.

Trixie will definitely make an appearance as one of the rivals later on. I was also thinking of having Iron Will appear, but I'll give the rest of them some thought as well. Also, as an early spoiler, the boss in the next chapter is going to be a MLP villain.

Cosmic Eternity - "Believe In Yourself"? from Sonic CD? http://www.youtube.com/watch?v=4R7zb_uTH1U

Anyways, those seem like good choices, but for an opening and closing theme, I was thinking something along the lines of "Hikari" by Koji Wada from Digimon Savers as an opening theme, or some other anime theme that has that adveture-like feel to it. IDK really, I'm just telling what I feel, I'm sure there's an opening theme out there for this story somewhere that fits. This one I was just guessing.

As for the closing theme, I still think a TV sized version of "Super Sonic Racing" would seem nice as both Sonic and Dash are "super-sonic racers" in a way.

Anyways, I have a question of who the next MLP villian will be? Discord or NightMare Moon?

Wait! Here's a thought: Discord & Dr. Eggman working together as the main villians for this story. If I've guessed it's them behind all this, then yay.

But anyhow, My question is Applejack & Knuckels, they should both fighter together against The Flim-Flam Bros. don't you think? =3


I never was good at coming up with opening and ending themes. I only seem to be good at coming up with music to fit specific moments in a story.

Oh, it's going to be a surprise. I'd tell you whether you were right or wrong, but someone else might read this and end up having part of the story spoiled.

Flim and Flam, eh? Hm, maybe if they could find trick Knuckles into giving them something and he and Applejack have to chase them somewhere in order to get it back...

i only read two chapters and knew this was gonna be awsome!:pinkiehappy:

Tails being badass? Aww yeah.

I am REALLY sorry about the long wait for this chapter. It's no excuse, but I kept getting slapped in the face while I was trying to write this, particularly by school and a brief cold. I would've had this up sooner, but... you know, the whole server thing... I hope this chapter makes up somewhat for the long wait. Summer break will be starting in a few weeks, so I should hopefully have fewer heavy things on my mind for at least a few weeks.


Like it's mentioned in the story, the Boss Gate looks like the corridor in Canterlot Castle rather than the Boss Gate in the actual game.

Sonic claiming to not know for a fact that Eggman's real name is Robotnik is a reference to Eggman's Sonic Channel profile, which doesn't give his full name. And I do call him "Robotnik" at times, in case you were wondering.

Sonic's comment about traveling to Earth from the Moon is a reference to "The Moon Zone" from "Sonic Advance".

The crab-like creatures that Nightmare Moon brings to life were inspired by the Gen. V Pokémon, Dwebble.

Applejack using Twilight like a gatling gun was inspired by Pinkie Pie doing the same thing in one of the previews for the season 2 finale, "A Canterlot Wedding".

Let's see, anything else? Uh... nothing comes to mind. Let me know if you have any questions and I'll try to get back on track soon.

Now I've been thinking about what other levels I want to appear in this story. At the moment, I'm not sure what level I want to represent "Sonic Adventure". I've narrowed it down to three choices, but I can't decide. Here's what I've been thinking:

*Windy Valley (Tank the Tortoise could make an appearance here, flying alongside everybody)

*Lost World (Knuckles could come back to help out in a temple excursion worthy of Daring Do)

*Twinkle Park (something a little more lighthearted after the gritty Metropolis Zone and freezing Ice Cap Zone, and those fun house mirrors may not be as innocent as they look...)

Well anyway, that's what I've been thinking. I'll see you all later.

Of those three, Windy Valley would definitely the one I'd pick, seeing as it would be an excellent match for both Tails's and Rainbow Dash's skill sets. Additionally, seeing as the actual stage was right near Tail's workshop in the game, perhaps the Tornado could make an appearance. I wonder how Twilight would react to a giant chunk of metal flying through the sky...

I`m also with SciGuy.

Edit: Also, for the battle against Nightmare Moon I think these might be more appropriate.

Nightmare Moon, Phase 2 - http://www.youtube.com/watch?v=dLjEZW0y6ho

I would choose Windy Valley as it would be a great chance for Scootaloo to bond with her hero Rainbow Dash and for the both of them to learn from the best of buds with Sonic and Tails. :scootangel:

Plus it would be a great chance to see Fluttershy in this level along with Cream and Cheese since they both can fly. :fluttershysad:

I must comment on the clever way you handled Nightmare Moon in this chapter, without the aid of the other Elements. :ajsmug:


Well, Fluttershy and Cream and Cheese will appear next chapter, but they're going to be the next ones to be rescued. So they won't get a chance to fly with everybody just yet.


But, I have another reason why you can choose Windy Valley as your chapter..

The recent Hurricane Fluttershy Episode had ever Peagi pony in Ponyville, except for :scootangel: .

Having Windy Valley be a team up level with Scootaloo and Rainbow Dash along with Sonic and Tails could be a way for them to clear up the air on that moment and finally give out the answer of why Rainbow Dash never did ask Scootaloo to help out.

In a way it could be harsh of Rainbow to admit that Scootaloo can't fly, but only for her to hurt their "bond" and also it could be a moment where both Sonic and Tails could teach the two Peagi a thing or two about idolize a pony and how to truly be a friend to pony. It could be a moment for the two of them to strengthen their bonds together.

Plus, it would be interesting to see Sonic and Tails recall some of their own solo adventures and how much their partnership/friendship really mean to each other.

Do you get what I'm trying to say ? :unsuresweetie:


I do get what you're trying to say. I just think the challenge with Windy Valley is going to be the whole three areas thing. You know, going from the valley itself into a tornado and then up to a bunch of tracks and pieces of land floating in the sky. It's great in the game, obviously, but talking about it and explaining it might be kind of hard.

Then let me try to help you out...

Let's say that the gang find a portal near Fluttershy's cottage and the Everfree Forest, they also find a stoned version of Zecora.
Still, because of their recent battle with Nightmare Moon, Twilight and Applejack sit this one out a bit. Seeing that this could be her chance to work with her idol, Scootaloo volunteers herself into action, with Sonic and Tails encouraging her. Reluctantly Rainbow Dash agrees, as long as she sticks with them.

They enter Windy valley which seems simple enough, along the brief way Sonic ask Dashie about her connection to Scootaloo and she makes some comment on how the little filly looks up her in a way.

While Tails and Scootaloo hang back and let the elder speedsters take point, Tails speaks to Scootaloo a bit and they try to bond, with Scootaoo telling Tails about the other Cutie Mark Crusaders and Tails telling Scootaloo not to worry about not flying and tells her on how Sonic taught him that while flying is great, the journey of using one's speed is better.

Soon they reach the Hurricane moment and Sonic takes the lead of leading them out with quick speed, given the power of the hurricane is a bit too much for even Dashie to fly out.

When they reach the third part of the level, Sonic tries to teaches Scootaloo a thing or two about Speed, while Rainbow Dash and Tails fly ahead of them.

Soon they reach the end and find Fluttershy turned to stone along with Angel Bunny and Cream and Cheese.

And that's how I would have done the level a bit.

I mean yeah it would be a bit rush but that's the thing when you're dealing with speedsters, they love things fast a bit to enjoy the scenery around them. :rainbowkiss:

Wouldn't you agree ? :scootangel:

Wind Valley +1
Also, if you are going to make Shadow a boss, please make him fight Sonic only because he wants to make sure that Sonic is ready for the Time Eater instead of simply prove that he is stronger like he did in the original game (which doesn't match his personality at all), and after his defeat, he gives Sonic his Chaos Emerald (or just some random Chaos Emerald he found, since his green Chaos Emerald is in the castle ruins for no apparent reason)
Sorry if you can't understand me, English is not my first language

“Chao Emerald? That doesn’t sound like a good thing,” Applejack said.
Chao Emerald? It's a typo, right?


Whoops! You're absolutely right. Okay, fixed.


The green Chaos Emerald was in the castle ruins because both versions of the game list it as the first Emerald that's collected with the violet Chaos Emerald being second. And I agree; Shadow did seem a little darker than normal in the game.

Sorry about the long wait for this chapter. Between finals, moving out of my dorm, and just getting back from a mini vacation, I've been kind of busy. And since both Lost World and Windy Valley had a lot of storytelling potential and I couldn't stand to disappoint anyone, I had to have them both here. I hope that's okay with everybody. And be sure to point out any mistakes you see; I've been working on this for hours and I'm sure my proofreading skills have dwindled since I started.

The Twinkle Park idea I originally had wasn't as good an idea. The only really noteworthy scene I had in mind involved the house of mirrors Amy went through in her version of the level. Sonic and Tails would have seen their classic selves in the mirror and the ponies and Spike would have seen their G1 counterparts instead of their normal reflection (which could have led to a joke about Twilight's mother looking similar to G1 Twilight).

Anyway, proper chapter notes.

Knuckles following Tank is meant to be a reference to the ending of the Sonic OVA/Movie. You know, that scene at the end where everybody is watching the tortoise instead of paying attention to Robotnik/Eggman.

The first part of Lost World is based off of how the temple appeared in "Sonic X" while the rest of it is based on the actual temple from "Sonic Adventure".

Windy Valley has elements of both "Sonic Adventure" and "Mario and Sonic at the London 2012 Olympic Games" in it. The saucers the characters use are based off the discs used in the latter's "Dream Discus" event.

Twilight using a book to attack is a reference to her fighting style in the fangame "My Little Pony: Fighting is Magic".

Hope I didn't hint at too much with the Shadowbolts here...

The time travel scene is obviously based off of the cutscenes that play prior to the Perfect Chaos fight in "Sonic Adventure".

I hope I got Fluttershy down correctly. I was trying to capture how she reacted to meeting Spike in the first episode here, but I may have gone a little overboard here.

Anyway, that's enough out of me. See you all later!

Tails' speech is awesome (especially with the background music) and I love Fluttershy's reaction to Sonic and his friends.
A little suggestion: use Sonic Rush instead of Sonic 06 because Sonic 06 is non-canon so Sonic and friends won't remember it
Also, what do you think you are going to do with Silver's rival fight? Hope it is nothing like "Are you Sonic or an imposter? The only way I can find out is by THROWING CARS AT YOU!!!" (http://www.youtube.com/watch?v=aMBV93bhK1A)
Sadly, Shadow will be the third boss fight, not the fourth, so he can't be the guardian of the DAMN FOURTH CHAOS EMERALD.

“Ooh, you’re a fox! And you’ve got two tails! Are you one of those mystical foxes that I’ve read about?”
Does Fluttershy mean the nine tailed fox from Chinese/Japanese myths?


I'll think about using a level from Sonic Rush or Sonic Rush Adventure. Or maybe I could do level from Sonic Rivals 1 or 2.

I'm still working out how I want Silver to make his entrance, but I've come up with (what I think) will be a very interesting scenario for the Shadow fight.



I have to say, you surprised me in this chapter. I mean I didn't think you could pull off two different Sonic Adventure levels in one chapter, but you proved me wrong. :yay:

And you had specific moments of bonding between the characters in this chapter to boot. I mean Applejack and Knuckles are sort of alike in some ways. :ajsmug:

Plus I loved the talks between Sonic and Rainbow Dash over her actions with Scootaloo along with Tails giving Scootaloo some help on how to be herself and still look up to Rainbow Dash. :scootangel:

What surprised me the most in this chapter was the Shadow Bolts add-on as the enemies of this chapter, as I have always thought of them as part of Nightmare moon's illusions ? :rainbowhuh:

Also, great flashback to the end of Sonic Adventure as well as another mentioning of Chaos. Something tells me he may make an appearance in the physical form in this storyline of yours, am I right ? :twilightsmile:

Still, overall it was a great update and a few nice pieces of music to listen to as well throughout the storyline so far.

Man, I cannot wait to see who you'll save in the next chapter. :pinkiehappy:


You're right. The Shadowbolts in this chapter are illusions, just not specifically Nightmare Moon's illusions. They're the illusions of someone else...

He may, he may not. I haven't decided whether or not I want him to make an appearance yet.


I would love it Chaos made an appearance in the story, just to make a reference or two to the Hurricane Fluttershy episode of Season 2. :rainbowdetermined2:

Once again, you have impressed me.

The character interaction is top-notch, worthy of being made into an actual animated episode or movie cut scene for a game. I totally love how you got Applejack and Knuckles to get along, and I adore how Tails gave Scootaloo advice, the same for Sonic with Rainbow Dash.
And Fluttershy's reaction at the end of the chapter... I didn't really see that coming until I figured, "well, she did react to Spike like that the first time they meet, so yeah, that works!" And it worked beautifully! She reaction was PRICELESS! :pinkiehappy:

For future chapters, I guess you already have this in mind, but please have Rarity team up with Rouge! They be prefect! :raritystarry:

As for Pinkie Pie, I have no idea what to do with her. Maybe she be better off with Charmy Bee? =3 Cause somehow, those two seem like the only logical choice, since Charmy is just as hyper as Pinkie is! LOL! :rainbowlaugh:
I have no idea who should pair up with Blaze, Vector, or Espio.

As for Shadow and Silver...hmmm....

I'm got sure about them at all at the moment. But I do have suggestion: After fighting with them, Shadow and Silver should join the team - just to make it a bit different than the actual game, as they didn't show up to help until the very end (If I remember correctly).

I have another suggestion: have Trixie join forces with Shadow and be two vs two with Sonic and Twilight. That would be a fun idea, as I see Trixie being the "Shadow" of the pony group, when comparing the two casts. Although, I think Gilda would have been a better choice as the speeding bad-ass.

Also, for when getting back Rarity and Rouge, have the bosses for that stage be the Diamond Dogs. Or better yet, after Rarity and Rouge are rescued, have them team up to fight the Diamond Dogs. That seems to sound right, IMO. :twilightsmile:

Anyways, I hope my suggestions help you in writing future chapters. I may not have good ideas all the time, but at least I try. :twilightblush:

Keep up the good work.


Rouge, Rarity, and Sweetie Belle are definitely next on my list.

Well, don't think we won't see Gilda until the end. She will return before then, and there just might be a chance that she gets to work with Shadow in a way.

Yes, you certainly do come up with good ideas. I'll be sure to take everything into consideration while I'm writing future chapters.

I don't think Shadow should be team up with Gilda, it will be much better if he only works with Rouge. Also, Cream always address others as "Mr" or "Miss"(Except for Tails, because they are nearly the same age. And Amy, because they are close friends)


I know that. It's just, when she's rescued in the game, it's one of the few moments where she doesn't refer to Sonic as "Mr. Sonic". And, for some reason, she did call Tails "Mr. Tails" in one cutscene in "Sonic Free Riders".

NO, PLEASE, I beg you. Don't let out Sonic 06! This is the one chapter I'm really looking forward to:applecry:
I'm not telling you how to write your story because you are doing a GREAT job so far, but by letting out Sonic 06, you are ignoring some good story elements
Sure Sonic 06's events were erased, but games such as sonic rush adventure, sonic colors (ds) and sonic generations hints that the sonic 06's events are cannon... just not very good cannon.:pinkiesad2:
Back to the point, I always imagined that you could only pick flame core as the setting and basically, this concept write itself in a good way: Sonic and the mane 6 arrive in a burning wasteland, a subplot could be that they are trying to solve the mystery of how they could arrive there, sonic and his friends could have weird deja vu (but they are not gonna remember it), facing fire monsters, blaze getting a feeling she has been there and they all leave with questions unanswered... this writes itself as a kick-ass story:rainbowkiss:
I therefore asks you to reconcider sonic 06 in your story, because I really love this story so far and you are an amazing writer.
