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.

During an encounter with Dr. Eggman, Sonic activates a machine that wasn't ready yet, just as the evil scientist planned out. Endowed with the power of the Chaos Emeralds, which Sonic conveniently brought with him, the machine swallows the hedgehog and sends him into a new world, a world that has been divided for centuries and has lost all its magic. Now teaming up with a very optimistic unicorn named Izzy, Sonic will embark on a journey through the uncharted land of Equestria, to unite all the ponies, reclaim the magic, and hopefully find his way back home.

The battle against evil. A never ending cause that spans across infinite universe. Despite how different each and every reality may be, there is one constant. Good vs Evil.

But what happens when the evil forces of two separate worlds come together? Can one world's heroes handle another world's villains? The Elements of Harmony can handle any magical foe, but what will they do when their foe sends legions of mechanical monsters against them? And while the Freedom Fighters can smash through any machine, can they stand against the darkest of spells and darkest of souls? Can the heroes, who have such different tactics and stories, overcome their differences to take on the task at hand?

But above all else...is there enough room in this crossover to fit both Rainbow Dash and Sonic's egos? I hope so.

Spin-off story to "Sonic Generations: Friendship is Timeless", taking place between chapters fifteen and sixteen during the train ride to Canterlot.

Everyone knows that Sonic, Tails, Spike, the Main Six, Shining Armor, and Princess Cadance set out for and arrived at Canterlot aboard the Friendship Express to find and stop the monster that had intertwined two worlds and their fates together, but what happened along the way? While Princess Celestia and Princess Luna went on ahead and prepared for their arrival, Equestria and Earth's heroes had to go through more adventures in order to get to Equestria's capital city. Now, the story of their lesser known adventures shall be told.

So climb aboard the Friendship Express, grab a seat, and get comfortable. It's going to be quite a ride.

This story is a sequel to Sonic Generations: Friendship is Timeless

Everything seemed to be going so well since the fall of The Last Ancient. Twilight and Starlight's time in Sunset Shimmer's world had granted them what they thought would be the final piece of the puzzle that they needed to reach the world that Equestria had almost joined with due to the disruption of time and space. And then Princess Celestia and Princess Luna announced that they would be stepping down.

In her efforts to restore the Warp Ring in the hopes of seeing Sonic and his friends one last time, Twilight inadvertently provided an easy back door to Equestria, allowing Dr. Eggman's chief enforcer to reach it and eliminate any threats the land may pose to the Eggman Empire. As part of his revenge for foiling his plans in the past, Eggman gave strict orders to drag Twilight and her friends to his world so they might see his glorious reign before he ends them for good. Luck proved to be in their favor, however, as the arrival of two friends who haven't been seen in a long time threw a wrench in the works and allowed them to be found by a band of freedom fighters known as the Resistance, led by more of their old friends from that world.

Now part of the uprising to reclaim the world, the Equestrians are hoping to help their allies, new and old, win their war, but time is not on their side. It is the darkest of times for the world, but their efforts may prove to be for naught against their seemingly unstoppable enemy.

Will their friendship and the smallest amount of courage be enough to turn the tides of war?

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 Sonic Generations: Friendship is Timeless

Totally not a spin-off to "Sonic Generations: Friendship is Timeless"; it is a sequel.

When an old, Ancient enemy resurfaces in the world of the Blue Bomber and his heroic friends, craziness ensues when they try to stop him that ends up sending everyone to a whole other world.

Stranded far from home, Team Sonic must make new allies and attempt to fit in in this new world while also trying to gain the trust of its inhabitants and reclaim the Lost Crystal of Power before their foes do.

Will Team Sonic be able to balance a life of their typical heroics with going to school? Will their new friends be able to show them new powers they'd never imagined were real before? Will Amy finally get her new snakeskin boots? And will Sticks eventually stop messing with the author?

"Don't count on it."

Find out in this, the ultimate crossover of awesomeness!

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.
