Tanya Degurechaff gets tossed into Equestria and transformed into a Changeling Queen. It's a nice retirement from modern warfare as an aerial mage. Then Queen Chrysalis attacks and forces her out of retirement. Historians refer to this as 'a bit of an oopsie.'

Years before a certain prophesy would come to fruition, a young pegasus filly fell from the sky near Las Pegasus, only to be rescued and taken in by Burning Sky and Dragonfly, a newlywed pegasi couple on leave from the Equestrian Air Guard for their honeymoon. Adopted and named Firefly by the very ponies who caught her out of the sky, the young filly is secretly a being from another reality, a former human who had been a fan of a popular show that had portrayed this very world (or one very similar to it), with no idea what had brought her here, why she was now a pony, or even when in the timeline she happens to be.

Once she figures out that she's in the past, with years before Princess Luna returned as Nightmare Moon, young Firefly resolves to simply stay out of the way and let events happen as they should. However, once she sees Princess Twilight Sparkle and Spike the Brave and Glorious appear out of a bubble of complex looking magic, Firefly feels an incredible sense of liberation, believing that it no longer matters what she does or doesn't do as everything would correct itself once Twilight dealt with Starlight Glimmer and returned to the future.

So Firefly decides to buck Starlight Glimmer on the way down to save Fluttershy.

After all, if nothing she did right now mattered anyway, why not be the hero? What harm could it possibly do?

And thus my SI takes a sledgehammer to causality, breaking Starlight Glimmer's spell in the worst way possible for two mares and a dragon from the future and changing the course of history forever.

But hey, at least Fluttershy is okay, right?

What do you mean Fluttershy's Cutie Mark is different now!?

What we have here is a very annoying Plot bunny which never went away. All because the main character of Worm and a destroyer from WW2 share a name, then for some absurd reason my head says yeah! That’ll definitely work in my little pony. I can’t just let it be a standard destroyer though Worm has tinkers which could do cool things to the warship right? So what if there is little to no fighting in my little pony. I want a flying super destroyer which could probably blow up Malaysia.

“Sorry Taylor, the truth is. The game was rigged from the start. Gate!” Contessa shouts as a Gate open up just in front of Kelphri.

Taylor Hebert post GM

When Taylor Hebert of Earth Bet triggered within the Locker, it drew the attentions of Discord. While unable to do anything directly to help/improve the situation on Earth Bet, he decides instead to give Taylor the gift of Equestrian magic, plus some helping hooves.

As Discord would say, let the chaos begin!

This story is a sequel to And Now For Something Exactly the Same

Twilight Sparkle is now Princess Twilight Sparkle and she's successfully rescued Sergeant Lyra Heartstrings from spreading herself too thin into early burnout in Canterlot—by ordering everypony who might have some claim to the mare's time to surrender her at their earliest opportunity.

It's a new life for Lyra Heartstrings, a new set of responsibilities, and a new princess to serve. Now she just needs to survive Ponyville to fully enjoy this new future.

Waking up underneath the sea in the body of a pony mixed with a world war 2 warship was defiantly not how the newly named Yamato thought her morning would go. But since it did, she was going to find just what had brought her to this foreign land and fused her with a ship. Now she and three thousand members of her crew prowl the Oceans of Equis, intent on finding the rainbow light that seemingly brought her here. But Yamato's return has stirred up the ocean floor, and creatures never before seen rise from the Abyss to claim the oceans as theirs.

Will Yamato wield her cannons in defense of the innocent life of Equis? Or will she turn her 18' turrets on those who would prevent her from returning to her previous life? One things for sure, those who underestimate the might of Yamato will know the fury of greatest battleship ever built. (Kancolle Kantai Collection/MLP crossover/SI, not anthro)

Spartan-B312 A.K.A Noble six. The unsung hero and the only other Soldier designated as 'Hyper-lethal' of the Human-Covenant War. Were it not for her actions on Reach, the events that lead to victory over the Covenant and Flood would never have happened.

But that victory had a cost heavy price with Noble team dead and Six left on Reach as the Pillar of Autumn made for orbit.

Alone against the Covenant she was doomed. But she wasn't going to go down without a fight.

For three whole days, she fought. For three whole nights, she struggled against the full might of the Covenant on Reach. And on the third and final day, she fell.

Exhausted, battered, and beaten she was finally overwhelmed and presumably killed from what the helmet cam footage shows, the only thing remaining of the Spartan after the glassing of Reach was a broken helmet. But even after that, there is one constant that is never broken.

Spartans never die...They just go missing in action.

Now armed with a new equine body and armor to boot in a barren wasteland resembling the one she had just left behind, Six's Journey hasn't ended yet.

Character tags shall be added as the story progresses

If called upon by a ritual -
most demonic beings follow the call.
And on the other side of the magic stands -
a human being, in a trance.
Their wish will be heard and fulfilled for a price -
in exchange for a soul, demons play nice.

When a desperate person calls out into the void - what happens when the void stares back?
Lily Potter is a strong woman, but in the face of almost certain death, even someone like her can come to the conclusion to fight fire with fire, and call upon a demon to fight the inhuman Dark Lord tearing down her home.

Once called, Nightmare takes on Harry as her child... this doesn't bode well for the sanity of everyone else involved, especially once she finds a very special letter addressed at herself years later.

Disclaimer:
The Nightmare in this story is a (far) future version of the Nightmare found in my other story.
The 'Sex' tag is for roughly two sentences implying it in a chapter near the middle (hence this story's rating).
The 'Death' tag is for, well, the death of Harry's parents.

Well, I could place here a normal story description. But if I had to guess, we’d say you already know what we mean if here simply stands ‘HIE as Nightmare Moon’.
...
What? Too meta? The only meta thing you can’t write here is about the real world.

(Sex only implied, and NOT a main aspect in the story.)

We have all read the stories about a human waking up as N.M.M in the castle of the two sisters heck even I've read a bunch of them. They were always my favorite with a normal guy trying not to get blasted by rainbows for having the same body as some villain.

But never thought that could happen to me!

Now my hair is on fire, I'm most likely 6 years old and this castle I woke up in looks an awful lot like a certain one that located in the magical land of Equestria.

But that's only fiction right?

Well if there is one positive thing about this...I got to keep my hands.
