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.

The life of a Princess of Equestria is always a stressful one, whether you are an experienced one or not. Sometimes you need to get away from it all. That is exactly what Twilight and Cadence thought when they decided to take a trip to the Hoofwian Islands just the two of them. The vacation is suppose to be about having fun, but deep down one of them wants a bit more than that. Their only concern, though, is how the other will react to this.

When your life is as dull a gray as the world that surrounds you, the mundanities can make it all seem meaningless. Sometimes all we need is a little color -- or six -- to reintroduce us to what truly makes life worth living.

This story is a sequel to Past Sins

Side-story to Past Sins - Spike almost lost Twilight to a hangmare's noose, but now Twilight is safe and Nyx is a filly again. Normal life is returning. Still, Spike can't ignore the fact that Nyx just isn't the same as he remembers her. Her temper is more volatile, and, when she gets angry, all he can see is the rage-driven Nightmare Moon of legend.

And thus Spike has to wonder: Is Nyx truly reformed, or is she one bad tantrum away from calling herself Nightmare Moon again?

This story is a sequel to Past Sins

Hearth's Warming is a time for friends and family to come together, celebrate harmony, and welcome the new year. Nyx is looking forward to just this as she rides the train to Canterlot with Spike and Twilight. She's going to meet her extended family for the first time and wants nothing more than to make a good impression. Yet, the sheen of the holidays can't hide the trouble caused by meddling grandparents, relentless reporters, and a paranoid uncle.

This story is a sequel to Past Sins

Side-story to Past Sins - Slowly, the wounds inflicted by Nightmare Moon's reign heal. Ponyville is being reconstructed, and the last refugees are leaving the castle. Nyx is with Twilight. Celestia and Luna rule Equestria and guide the sun and moon once more. Everything is as it should be.

But some things are never washed away. These are the things that remain to remind us of the past. They remind us of the good times we've had with friends and family. They never let us forget the mistakes we've made. Everyone has them. Twilight has them. Nyx has them.

And, on occasion, when you share your scars, your photos, and your trinkets with another, they just might share theirs in return.

Upset about the humiliation she got from the ponies and a former friend of hers, a filly has been chosen to join the evil Apocalypse Ponies. She willingly agreed to join for the sake of destroying all the "blank flanks" and traitors to the "right kind", even if it meant leaving the family she had that supported the ponies.

When Rainbow Dash finds herself lost in a new and unfamiliar village, she reaches out to a certain lavender-hued stranger for help. But to Twilight Sparkle, Rainbow Dash is no stranger; at least until she notice her strange new voice, a lack of wings, and a fondness of the word ‘darling’. Intrigued by the uncanny looks to one of her best friends, she decides to lend the newcomer a helping hoof, but things go from weird to weirder when Pinkie Pie happily announces that she too has met her lookalike. Twilight Sparkle and her friends take it upon themselves to find out the truth behind this mystery: who are these doppelgangers? Could there really be another Ponyville out there? And what does it all have to do with Discord’s lost legacy?

Discord is once again loose, but after using his randomness to find some interesting information on some strange phenomenon in another world that has to do with an island and a bunch of humiliating events, the crazy spirit of disharmony and chaos comes up with a new, sick, twisted, disturbing plan that involves capturing 20 of the most popular ponies (and three non-ponies) and forcing them to play a new game while the rest of Equestria watches in horror (or most likely secret amusement and possibly envy of not being picked themselves).

What does the rotten host Discord have in mind for our 20 unfortunate selections? Well, looks like you'll have to wait and find out! Maybe, just maybe, if Discord is feeling generous, the winner of his new "game" will get a grand prize. Everyone pick a character to root for and let's get it on!
