The time has come once more. In the wake of the remaster to the original "Sonic Generations" game comes this new story adapting its companion story, "Shadow Generations."

While on a mission to investigate a security breach at the ARK, Shadow is confronted by a face from his past and subsequently finds himself drawn into a whole new space where two worlds are colliding. The inhabitants of this other world don't matter to him. They're not part of the world he swore to protect.

Right now, his focus is on confronting this old enemy from his past and dealing with the changes this strange space is causing in his body. And along the way, he'll meet faces, new and old, that just might help him make the choices that will once again determine his destiny.

Will he be able to reconcile his past when confronted with it once again? Are the inhabitants of this new world truly worth nothing to him or will they prove that they are more than they seem? And will he find harmony amongst all the chaos?

Find out in "Shadow Generations: Harmonia in Chao!"

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 moustachioed 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 moustachioed 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.

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.

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.

It all started with a flash, strange beings appearing from out of nowhere. No pony knew where they come from but the pain and anguish wreaked upon them told them that they had been through enough of an ordeal to not refuse their need for help.

Let’s just hope that they had made the right decision.

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?

After being defeated by Sonic and Rookie, Infinite is teleported back to Dr.Eggman's Empire Fortress Tower, however he's send to Equestria, where the Royal Sisters found him.
Unknow to everypony a new threat rises below the horizon, which Infinite's powers maybe come of great use to the Princesses for what's about to happen. Will he agree to aid them?

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.
