Pinkie Pie has a secret. Actually, more like fifty secrets. 

See, Pinkie isn’t really Pinkie. She’s actually a whole hive of changelings, working in shifts to absorb as much love as they can. Ordinarily, that works out fine for Grasshopper and her sisters--but what happens when somebuggy breaks the rules? 

Note: This story uses colored text for some important bits. Readers with colorblindness or using monochrome displays may have trouble. If it's getting to be too much of a problem, drop me a line, and I'll see what I can do!

Inb4: Yes, this AU makes no sense and doesn't stand up to scrutiny. But it's a Pinkie Pie story, for Chrysalis's sake. Just enjoy it.

This story is a sequel to The Irony of Applejack

Warning: this story is a sequel. Therefore, it is highly recommended that you read the prequel first before continuing!

Over half a year has passed since the changeling attack on Ponyville, and Applejack would like to think things have finally settled down. Much has changed for the young changeling, and all of Equestria in kind. The new district in Ponyville proves that, along with the town's many new residents.
But there is much the young queen does not yet know about being a changeling. Some things, she will learn, can be chosen, while others will be chosen for her. With new allies and enemies emerging all around her, Applejack must discover what it truly means to rule before the choice is taken from her forever, and the history of the changelings repeats itself, once again...

Rarity finds out that she is in fact a Changeling,and more then that, a member of a Changeling Royal Family,who was sent away for her own safety and so that she should not get spoilt.

Rarity as carry a secret about herself for all her life, a secret that only her parents know of. But after a fated meeting at a wedding in Canterlot, Rarity finds out a lot more about herself, then she ever could imagine.

When her 'brother's wedding day comes, she thinks of nothing but that it will be a drag. But when Twilight discovers that her mother is undercover, Twilight is happy, knowing that maybe the wedding won't be as bad as she expected.

Applejack couldn't help but notice that Twilight has been acting weird all the time. Will Twilight be able to keep up her cover or will everypony discover the truth before she and her mother can begin their plan to attack Canterlot?

Cadence wasn't always an alicorn, and neither were Celestia or Luna. They used to be something altogether different—technically, they still are. In reliving Celestia's past, Twilight takes Equestria's future in her hooves. Time will tell what she does with it.

The Alicorn Delusion is a prequel to Magical Mystery Cure.

(Takes place in AU during "To Where and Back Again, Part 2" for obvious reasons. Idea inspired by LittleshyFiM.)

When Thorax stops holding back and starts sharing love, magic is unleashed that causes not only the changelings to change but Starlight as well. In fact, the magic ends up changing her species completely.

To the shock of everyone, Starlight Glimmer is no longer a pony. Now, she is a changeling, and the queen of the changelings to boot.

Overwhelmed with this sudden change and the responsibilities that come with it, Starlight must quickly adapt and try to be a leader for her new hive. And this includes what to do with the former queen, Chrysalis.

Twilight Sparkle never was a Unicorn and she didn't even know it.
What happens when her true heritage comes to light? Will she willingly embrace it? Or will she be forced to?

All her life, Fluttershy felt different from the other pegasi. She preferred the ground to the clouds, and the simple love of her animal friends always seemed to refresh her... And she never really had to eat... She didn't remember her parents, either...

One day, though, her life changes forever, when she and her best friends find out what she truly is.

My name is Rainbow Dash and today I learned something new. I learned I'm actually a changeling. You'd think that would be something you would already know. I just learned it now when I saw my true self for the first time. How did I come to replace the real Rainbow Dash, and when? And why can't I remember it?
