Applebloom just wanted to spend a day with her friends, crusading for her cutie mark. Instead, she found something even deeper and more troubling about herself. Turns out she's not even a member of the Apple Family by blood. In fact, she's not even truly native to Equestria! She's an alien! An alien robot no less!

Now Applebloom will have to deal with the reality of her origins and try to cope with them and her newfound abilities as she moves towards her future; a future that just might never come to be if her new foes have anything to say about it. Decepticons are, after all, a monstrous cabal.

Now, it's up to Applebloom to light Equestria's darkest hour.

Takes place in an alternate universe where Celestia and Luna used the Elements of Harmony to slay King Sombra.

Celestia and Luna are no more. The sun and moon have collided, and the heavens torn asunder in the aftermath of their final battle. The Elements of Harmony are missing, presumed forever lost. The fiends of Tartarus are on a rampage, and no one can stop them. And to make things perfect, the ruler of the nation of Boardor has decided to invade.
Desperate, Clover the Clever's last living student gathers together 108 virgin mares, in order to perform a ritual that will revive King Sombra. They succeed... kinda.
A human, in King Sombra's body, suddenly finds himself in an Equestria in a downward spiral with a bunch of technicolor ponies begging him to save them. Convinced that he's either dreaming, stoned, or insane, he tries to go along with it as best he can, although the voice in his head, a very angry voice with a hunger for conquest, crystals, slavery, and stairs, isn't doing much to instill confidence in his own sanity...

This story is a sequel to How Much Is Freedom Worth?

Aphid, a changeling, is now free of the cage that held her, and the life she'd been forced to live as part of the changeling swarm. Employed now as a maid for the family that helped free her, she struggles to understand something that she's never had before...
Freedom.
But the past has a strange habit coming back to haunt us, and it seems as if every employee in the Mason de Bleu has a secret... including Howe, the changeling who serves as the head butler.

My name is Pinkamena Diane Pie, although most ponies just call me Pinkie!
Or if you're my sister, Maud, you may also know me as Pinkamena, Surprise, D, or Inkril.

Life's been going good for me, except for one little snag. Twilight's starting to ask questions and I really don't want to tell her the answers. There's nothing wrong with me; I'm a perfectly healthy mare that just happens to have some friends in weird places.

Luckily Maud is coming to visit Ponyville for spring break though; she'll know exactly what to do about Twilight.

Due to the sensitive subject of Dissociative Identity Disorder that this story covers, it may have triggers to some individuals, but I will do my best to try and mark chapters with such content.
This story also covers what it's like to have DiD, how it can affect your daily life, and how it can affect your relationships with those around you.

A changeling and a young filly are tricked into venturing to an alternate world, one locked in a permanent cycle of war between legions of monsters, and strange creatures called 'hyu-mans'...

Shortly after arriving, the changeling does something that may ultimately end the cycle of war, but only in the most disastrous way imaginable...

But... it can't really be possible to 'break' the world... can it?

This story is closely linked to Nor Iron Bars A Cage, and loosely linked to Saving Sombra.

Leiurus Quinquestriatus, the Deathstalker, a changeling raised to be a living weapon, is left without direction after the Canterlot invasion. Found by The Great And Powerful Trixie, she is taken to the Crystal Empire, in the hopes that somepony will take her in. However, Leiurus was given very specific orders regarding the Crystal Empire...

Orders regarding its destruction...

Part of the rebooted Cricket-Verse, aka The Nonsense-Verse.

Hiro Ecks is a gamer. After he was used as a cat's-paw in a villain's evil scheme, he is left traumatized, and just about ready to swear off video games forever. 8163264128 is a changeling. Almost pathetically incompetent when it comes to fighting, she is stranded at the entrance of a ruined palace, unable to escape due to her damaged wings. Fate, chance, or something stranger still has forced the two of them together. Hiro, through the medium of a small golden orb, has to win the changeling's trust and guide her into the depths, for the only chance that 8163264128 has for escaping the ruins is to reach the bottom of the catacombs beneath the palace, where a treasure beyond compare awaits... a wishing star. But between the two of them and their goal are fifteen floors of monsters, traps, sliding block puzzles, bosses, and more.
Rated Teen For Language
A Spin-Off from The Changeling Who Broke The World. Not strictly necessary for reading, but it will provide some background into Hiro's story.

Pinkie doesn't tell ponies about Pinkamena and Surprise. The doctors said that they were bad for her, that they were a disease, but she disagrees. Sure, Pinkamena's a bit of a grumpy-pants, but she's still a great friend! She's often the voice of reason to counter-act some of the other two's crazier ideas, after all. Surprise, on the other hand, is a great prank-player, and always up for some fun. She's more like Pinkie, only more hyper. Both are great fun to be around, and they get on well.

Thing is, she knows that if she told ponies about them, then they would be dragged back to the hospital. And then be 'treated' again. None of them want that. Because of this, not even her best not-in-head friends know about them. The three of them have, for years now, been careful enough to keep the existence of Pinkamena and Surprise secret.

This has, of course, gone out the window now that Twilight is hammering on the door after overhearing one third of a conversation, with no sign of anyone else talking.

Hints of F/F shipping inside. Nothing will actually come of it here, though. Maybe in a future story.

Pandinus Imperator (You can call him Pan, he won't mind) is knocked back in time during the Canterlot Invasion, and accidentally kills King Sombra on arrival. Instead of being executed, the changeling is surprised to find himself being hailed as a hero, and is promptly put on the throne as the new monarch, the Crystal Emperor. However, Pan now faces a great many problems, among them Celestia and Luna, who seem certain that the changeling is secretly up to no good, as well as several political factions secretly plotting to undermine his reign. There's also the tiny problem of the constant snowstorm that threatens to cut the city off from the outside world permanently.
The Crystal Ponies need a hero now more than ever before. Why did they get a changeling instead?

While not truly a part of Bucking Nonsense's Changeling-Verse, the same rules regarding changeling abilities and society apply.

When Canterlot pays the price for one of Twilight Sparkle's greatest mistakes, hundreds of refugees from the ruined city are stranded in Ponyville. Can the princesses maintain order in the overcrowded town, or will the combination of clashing cultures, Discord's antics, the machinations of a criminal mastermind, and outrageously bad luck send it spiraling into chaos?
