This was it. Sonic knew it was now or never. He had to do this. To save his friends, his enemies, his home. The last his friends saw of him was the super-powered hedgehog being launched from a giant rifle, straight through Supreme, and through the fake moon in the sky.

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.

After saving her friends from the evil Metarex, a Seedrian named Cosmo has been sent to Equestria instead of the death she was expecting. When she arrives, she is found and brought in by Princess Twilight Sparkle, who was preparing to take the throne and rule Equestria alongside her friends. While trying to find a way to make it back home and to Tails and her friends, Cosmo settles in to her new home in Equestria and makes new friends and memories with the new world's many inhabitants.

This is a story set during the ninth season of My Little Pony: Friendship is Magic, and after the events of the third season of Sonic X. All characters belong to Hasbro and SEGA, respectively.

This is also my own contribution to the #SaveCosmo campaign, and is a separate entity compared to my previous entries. If you're a fan of Sonic X's Cosmo the Seedrian and would like to support the cause, you can check out the campaign by clicking this link.

This story is a sequel to Harmony of Chaos

Sequel to "Harmony of Chaos". 15 years after Discord's defeat and rehabilitation, the scattered mane 6 regather at last in Canterlot...along with their children. As new friendships are formed and old pains are addressed, a great darkness arises, as past nightmares return to haunt our heroes. Can their children grow into their new roles and save all?

After the Phantom Ruby had been destroyed, Sonic the Hedgehog had expected to land back into his own world and finally find some time to relax. Instead, the blue blur managed to ended up into the magical world of Equestria during the middle of the first ever Festival of Friendship.

However, things quickly take a turn for the worse as the fearsome Storm Army attacks, enslaving everyone in the city and turning three of the four princesses to stone.

Now tasked with collecting the Chaos Emeralds, protecting Equestria, and finding a way back home once more, Sonic will set out on brand new adventures from a grand world expedition beyond Equestria to teaching at the first School of Friendship, but not without the help of some new friends along the way.

On the Eve of the Summer Sun Celebration, the forsaken Princess, Nightmare Moon returns to claim her vengeance upon the ones who had shunned her and her night. As Nightmare appears and lashes out at Twilight, a rushed defense spelled causes an unknown being to crash onto the scene right after Nightmare, saving the lavender unicorn in the process. With a cocky grin and devil don’t care attitude, the unknown blue creature smirks and challenges the Nightmare without a second thought.

The first rule of sending someone to another dimension against their will is to make sure it isn't done in front of their loved ones.

Apparently Infinite and Eggman never learned this rule.

A change in plans for Sonic's fate after Eggman's first attack combined with a desperate intervention from Tails sends Sonic to Equestria, where Rainbow Dash finds him after he interrupts a catnap... she wasn't exactly expecting him to start calling her "Mama."

Part of the Multiquestria series.

Now on AO3!

Questions I'm sure are going to be asked/points that are probably going to be raised, and my answers

Why Sonic Forces? You should have used [other Sonic media]!
Very simple, dear reader... I don't own any games other than Forces, I haven't watched much of Sonic X, and Sonic Boom and the 2020 movie would be hard to work in the return home arc.

This is awfully similar to the stories in Tatsurou's PWNY-Verse...
That's intentional! This is a tribute fan spin-off story thing to the PWNY-Verse... Although if you're comparing the actual writing to Tatsurou's then that's probably the biggest compliment I could receive for this :D

Are there gonna be more of these?
There’s one already been one published featuring Dipper and Mabel Pines from Gravity Falls as raised by the Apple family and there’s a few others planned. You can check out the full planned list and make your own suggestions on this forum post.

Why'd you even write this?
1, it's the anniversary of the publishing of Fortresshy, the first PWNY-Verse story, and I really love the series and wanted to celebrate it somehow, and 2, I had a couple scenes pop up and by the time I'd finished typing them up in Google Docs I had a bit over 9,000 words that I wasn't quite willing to waste.

This story is a sequel to Sonic The Hedgehog & My Little Pony The Movie

After defeating the Storm King the mane 6 open up a school with the purpose of spreading friendship to other creatures, meanwhile Sonic tries to get used to his new life in Ponyville and even attends the new friendship school.

But along the way there will be some problems, including a skilled hunter who´s after Sonic but it’s nothing the heroes can’t handle… right?

This story is a sequel to Through The Multiverse

One year. It has been one year since the defeat of The Exiled and the restoration of the Foundation of all Dimensions. In that time things have drastically changed for one Twilight Sparkle. She ascended to Princesshood, gained a new castle and a new student on top of that in the form of Starlight Glimmer.

Things couldn’t be more perfect for her.

But when the evil speedster known only as The Reverse-Flash assembles a team of villains to scour the Multiverse in search of a weapon capable of changing the very fabric of reality, The Guardians of the Multiverse must reunite once again to stop this Legion of Doom from changing their very existence.

Can Twilight and the other Guardians stop the Legion from changing reality, as well as help Starlight Glimmer find her place in the grand scheme of things?

Or will the Multiverse be forever changed?

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!
