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

WARNING: There are major spoilers in the comment section. You have been warned!

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.

This story now has TV Tropes page!

For as long as Equestria Online existed, Ashton has been involved with 'the Scene' tearing it apart. Selling 'spells' for the game to do things that most ponies in Equestria couldn't, using faint exploits in its API to erode the barrier between the game and the rest of the internet. He had no illusions about the superiority of his work--but so long as he respected CelestAI's boundaries, his spells kept working.

But then his best friend's sister got cancer.

Now there's no spell in the world that can keep him from emigrating to be with her, leaving Ashton alone. All around him, civilization's thin veneer crumbles as homes empty into Equestria. But Ashton isn't going to emigrate, not if he has any say about it.

The problem for Ashton is that humans are systems, and aren't immune to exploits either.

Part of the Optimalverse universe of stories. If you've never seen a story in this universe before, you might want to try out the original first, or at least my first. None of my previous work is required to understand this one, however.

This story was commissioned by Two Bit, who requested a more serious exploration of identity, transformation, and the fae nature of CelestAI.

As usual, particular thanks go to my editors Two Bit and Sparktail. And gratitude to Zutcha as well for the cover.

This story is a sequel to Transistance

Equestria a thousand years into the future. Powerful entities would spare no expense to prevent sentient machines, Equestria's primary workforce, from ever becoming legal citizens. Others, shown the error of their ways, will come to lengths to repair their past mistakes. Trust lost once is hard to restore, but a gift of extreme generosity comes a long way.

This story is an unofficial one-shot sequel to excellent Transistance by ToixStory. Reading the original is mandatory, otherwise this story won't make much sense to you.

(This time I got author's permission for the sequel.)

Updates Every Other Friday!

Humanity was headed towards a new frontier in the year 2022. The Portgate, a wormhole through time and space, would soon bring man from his little blue globe into the infinite universe. Soon, humanity would be able to forever explore the unknown to its heart's content.

Of course, things are never as easy as they seem.

The first world they find is a beautiful yet dangerous one, populated by monsters both big and small that lurk in the trees. Hardships pile onto those who pass through the Portgate like lead weights, dragging them behind from all angles. And the world is already inhabited by uncannily familiar civilizations wielding strange, mystical powers as easily as they breathe.

The future of humanity and those who it touches are in the stakes as each decision both sides make impacts their worlds for millennia to come. Whether they make the right or wrong ones is up to nothing but fate and fortune.

At first blush, they don't have much in common. But their connection runs deep, and sooner or later it will change their worlds forever.

The planet is on borrowed time. A gamma ray burst, a dramatic event that ranks as the most powerful explosion in the known universe, has set its sights upon Equis. A mad scramble for salvation ensued. The Equestrian space program kicked into overdrive with a single purpose.

To save ponykind from complete extinction.

The rescue craft, dubbed Friendship One, prepares for departure. With them, the crew carry the hopes and dreams of an entire species. Those who remain behind can only watch and pray for their success as the world they knew turns to ash.

Voidmarines.

A new wing of Equestrias military, created shortly after the first space colony, Horizon. Many graduates of military school dream of joining their ranks and so does Shetland.
