After discovering that Cadence is not who she appears to be, Twilight is sent to another world entirely by the disguised Changeling Queen to avoid her plan being disrupted.
When Twilight lands, she discovers that not only have Spike, Owlowiscious and Peewee followed her, but that they've arrived in a world where the main sentient species is human.
There's still a place where they teach magic, though.
Crossover with Harry Potter. Twilight will be effectively taking the role of Hermione.

I've marked this story as cancelled to reflect the unlikelihood of it continuing. If I do come back to it I'll revert that.

Now with our own TVtropes page! Help us catalog the awesomeness.

Holy crap we've got a trailer too!

Ulquiorra Cifer was defeated at the hands of a mere human and died in Las Noches. Or at least that's what he thought. In the boundary that separates life and death for all Hollows, he's found by one that finds him interesting enough to give a second chance at life free from Aizen's control, and free to do as he pleases; he was just never told that his second chance of life would take him to an alternate world he never could've imagined even if he tried.

The land of Equestria is a magical place full of hope, and second chances. In this land where friendship is considered the most powerful magic in existence, can the Cuatro Espada find something that's been missing and learn how to live? Or will his presence be the downfall of the peaceful world and all of its inhabitants?

Arceus has been imprisoned for many millennia, and in that time he has watched his world fall apart. But once he is finally freed from his prison he decides that to protect his Pokémon, and his family, that he will move the Pokémon, and a few select 'humans' to a world where they might live in peace, Equestria. However, not everyone on this new world shares his view of peace and the very presence of the Pokémon upsests some of the citizens of the world, even some of the ones he brought with aren't too happy with the situation. But a god's will is a strong thing and without his willingness the Pokémon and the citizens of Equestria are going to have to learn to get along, or at least tolerate each other. And there's a slight problem with some of the humans too, well, former humans that is.

I also have a Tvtrope page that is kept somewhat up to date by Kingofsouls if you know how to Trope, and want to help set it up, go here Tvtrope Link.

Since a lot of people keep aking this I'm gonna put an explanation here. I'm not following any one canon-verse here, I'm making a hodge podge universe with bits from the Manga, Anime, Games, and Movies, as well as some etcetera concerning issues addressed in none of them to great lengths. (Arceus' power is far beyond what he has in the games or movie and this does contain some Pokephilia, which comes from pretty much no canon material ever.)

When Twilight Sparkle slipped beneath the covers last night, everything had been fine. She had friends whom she loved, a teacher she adored, and a bright future ahead of her. But when she woke up, her blankets and quilts had been replaced by hospital gowns and padded restraints.

Everything is wrong and nothing makes sense; even her friends have changed. The doctors keep telling her that she is sick, that none of it was real and that it was all in her head. Yet she remembers a life far beyond the hospital walls. She couldn't have made it all up on her own. They must be lying… right?

In the dark depths of Asgard, Loki Odinson sits, punished for his crimes on Midgard.

But new developments cause the wayward son of Odin to escape his prison and seek refuge across the Nine Realms in a land very much unlike any he has ever seen: Equestria.

While Loki makes a new life for himself in Equestria, Thor must once again gather together the Avengers and give chase to his escaped kin. But will the lies Loki feeds his newfound friends send the Elements of Harmony on a collision course with the protectors of Earth?

Everyone in the Foundation knew 682. Most of them knew not to talk about him. Not to talk to him, more importantly, for fear of invoking his wrath. That creature made every single thing in the facility frightened, and they knew they couldn't do a thing about it. So what happens when he vanishes without a trace? Chaos. Absolute chaos. But this isn't about what happened there; this is about what happens to where he was transported. Which, coincidentally, is precisely the same thing.

Dedicated to everyone's favorite hard-to-kill reptile. You my boy, hamdoggz, for providing such an awesome rendition of it.

Celestia gets four unexpected new arrivals, with an agenda of Biblical proportions. But can the princess postpone the Earth's Judgement Day by introducing the four ponies of the apocalypse to the power of friendship and magic?

Caution: Biblical themes abound, even if slightly irreverent.

GLaDOS, the one powerful AI that ran the Aperture Science Enrichment Center, has been turned into a young Equestrian after being tossed in a realm where true science is unheard of and Magic is the primary factor in the advancement of civilization. As she matures, she'll experience normal everyday occurrences like saving the world from invading xenos, preventing a disastrous outbreak, over-throwing the current ruler of the throne, and other various things. No biggie, right?

So who is ready to do some science? And make 60 bits? Cash.
