Based on the movie: Sonic the Hedgehog, but with some changes.

After fleeing to planet Earth, Sonic the Hedgehog has been secretly living in Canterlot City as his new home for the past decade along with his incredible power of super speed. Things went well for him, until he accidentally knocks out the power grid, getting the attention of the military organization, G.U.N., along with the evil genius, Dr. Robotnik.

Meanwhile, the Equestria Girls was preparing for their upcoming graduation, leaving Sunset Shimmer unsure of her future. When the power grid near their school was knocked down, CHS was in suspicion by G.U.N., sending in a special agent to investigate as a result.

When the two groups meet up due to circumstances, Sonic and The Equestria Girls must team up to retrieve Sonic's rings and stop Robotnik from using Sonic's power for world domination while fleeing from the government.

After a good day passed crusading, Scootaloo is napping before returning to her home when a rift suddenly opens before her. Out of the rift comes a strange ruby followed by a bipedal mustachioed being. Scootaloo quickly discovers that the ruby possesses great powers but before she knows it, she accidentally merges with it.

Now, she has to learn to control her new phenomenal powers, fight the mustachioed being who reveals to be a mad scientist who wants to use the power of the ruby to return home (and conquer Equestria on the way), and deal with the spirit of a sicko trapped in the ruby calling himself Infinite.

Perfect setting for the rising of a new, awesome super hero: Zero.

Crossover with Sonic the Hedgehog. Starts during season 4 of My Little Pony and after the events of Sonic Mania Plus.

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.

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.

This story is a sequel to Equestria Girls: Sonic the Hedgehog

Based on the movie: Sonic the Hedgehog 2, but with some changes.

Eight months after settling in Canterlot City, Sonic is eager to prove that he has what it takes to be a true hero. His ultimate test comes however when the evil Dr. Robotnik returns, along with his new partner, Knuckles, searching for a mysterious mystical emerald that has the power to wipe out civilizations.

Meanwhile, graduation is growing near for CHS, but the upcoming ceremony and pre-graduation party were ruined due to an “incident” by the CMCs. Luckily, the whole school, including the Equestria Girls, were invited to a trip to Hoofolulu, Hoovaii to have their graduation there by none other than Twilight’s favorite astrophysicist, Rosette Nebula. 

But there is just one problem. The Dazzlings were hired as music entertainment for the event instead.

While the Equestria Girls investigate the Dazzlings' sinister plans, Sonic teams up with the CMCs, Spike, Tempest Shadow, and their new allies, Miles "Tails" Prower and a mysterious new man who called himself, “Prism”. And together, they all race across the globe to locate the emerald before it falls into the wrong hands.

Thanks everyone!

Sonic, Shadow, and Silver have been sent to the world of Canterlot High along with the seven Chaos Emeralds by the Master Emerald after hearing of a prophecy about the fate of worlds. They will have to go through school again if they are to regain the seven Chaos Emeralds and saved the worlds from the eternal darkness, for the emeralds have been claimed by some of the students of Canterlot High.

Long ago in a distant land, Ivo Robotnik, the egg-shaped master of science, unleashed an unspeakable evil. But a brave blue hedgehog wielding supersonic speed stepped forth to oppose him time and time again. Before their latest confrontation reached its climax, the villain tore open a portal through time and space, and flung him into another world where magic and fantasy are everyday reality. Now the hero seeks to return to his world, and stop the mad doctor from conquering this one too. Along the way he'll meet new friends, new enemies, and just maybe something a little more. All while the fate of two worlds hangs in the balance.

Hang on to your seats boys and girls, cause we're breaking down the walls between dimensions.

Now on TV Tropes.

After some inspiration from from my good pal Gunflame, I'm throwing my hat into the ring for a good Sonic/MLP crossover. And I aim to give it the much needed improvement in quality that's so desperately needed with this particular crossover genre. I'll strive to make this one of the premier Sonic/MLP crossover stories on the web.

Thank you and enjoy.

A factory worker with no future and a bored dimension hopping vampiric troll. Two beings who would have never met by anything but a sheer 1000000 to 1 chance.
The chances of said vampiric troll taking an interest were just as low.

Yet somehow, despite all odds, I caught the attention of Kischur Zelretch Shweinorg, the master of the kaleidoscope magic. And rather than troll me, he decided to help me. He gave me a chance to start over, and I couldn't be more grateful.

Though he could have told me what was in these coffins!

I may be in a world that if far from home on my own with concepts that I have not entirely grasped yet for 200 years, But there is a new threat in this world, the elements won't stop it, the powers of the sun and moon won't stop it, heck, not even Discord can stop it.

But I know I can beat him, But I have to get the Chaos Emeralds first before I know I'm ready.

I may not be beloved by all of Equestria, but I can't deny I have a duty to defend those who can not defend themselves. Even If I have to give it my all.

So for the love of Equestria, I won't give up, no matter what you throw at me! Even if I have run from the rulers of this world themselves, I will never be brought down.

So let's get this show on the road!

Emerl Displaced.

Not gonna be ready for crossovers for a few chapters.

Also takes place between Season 4 and 5.

Set between MLP:FiM Season 3 and 4.

Sonic, Tails, and Knuckles find themselves against Dr. Eggman once again, the scientist wanting to use the Chaos Emeralds for an unknown plan.

Unfortunately, the plan involved sending the trio to another world, which he plans to conquer as well as seek what are known as the Elements of Harmony. The fate of Equestria hangs in the balance as the heroes of both worlds must join forces against Eggman's robot army.

Can Team Sonic and the Elements foil Eggman’s latest scheme or will they fail?
