After years of trying everything under the sun, the Cutie Mark Crusaders finally earned their Cutie Marks and realized their destines.

But destiny is a funny thing, and the Crusaders are in for more than they bargained for.

A visit from Princess Celestia starts the Cutie Mark Crusaders and their new friends Diamond Tiara and Silver Spoon on a journey of discovery the likes of which Equestria has not seen in thousands of moons...

Just what is "Trinity Magic"?

My name's John. I guess my last name doesn't really matter any more. Life is ironic, isn't it? Life nurtures all kinds of species that can get along, but it also creates the species that kills others. In fact, there are some species, who's sole purpose is the death of everything but itself. I'm talking about diseases, of course. Viruses, bacteria, fungi, and even parasites. All my life, I found these things interesting. I loved studying them, so naturally I grew up to be an epidemiologist. When I wasn't studying diseases or doing other basic functions, I was playing one of my favorite games, Plague Inc. It's a game where you try to wipe out humanity using diseases. Over the years, I've become a master of the game, to the point where it isn't really a challenge anymore.

But, that all changed when the game sucked me into itself, and I wind up in a strange land, with even stranger creatures. But that isn't all. I've somehow gained the ability to create and control every single disease I can think of. Now, I have to survive in this harsh world, knowing that I'm one step away from wiping out the entire planet.

Like I said, life is ironic, right?

[Displaced fic]

To any newcomers reading this fic, I want to point this out. The story may seem confusing in the first five chapters, as I was trying to figure out how I want to write the story. I won't be getting rid of any chapters, but some small points might contradict each other across both of them. These points hopefully won't affect much of the future.

I was just hoping to get this last job done, always getting sent to this dimension or that, always doing the interests of others. Unfortunately, everyone's luck eventually runs out, and it looks like mine has ran out as well. Now somehow I got stuck in this place, in a foreign body, and things just keeps getting worse for me. What did I do to deserve this?

So I got in a car crash and the hospital put me under for surgery. The next thing I know, I wake up as a small pony with wings. And I can't see. And it's freaking cold up here.

At least I've still got my smokes.

(Got the idea from the funny picture. Rated T for language and tobacco use.)

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.

This story is a sequel to Iron Hearts: Book 2 - Ferrous Dominus

An MLP/Warhammer 40K crossover, part 3.

The formal negotiations between Equestria and the Iron Warriors have failed. Yet peace and even cooperation between the harmonious ponies and the corrupted militants blooms in the dark corners of Canterlot and the open streets of Ferrous Dominus. The Elements of Harmony are safe, trade flourishes, and cautious meetings grow into lasting friendships as an unsteady calm descends upon both forces.
Even the Tau threat seems to have mysteriously vanished as the Iron Warriors refuse to assault their hideouts and risk springing the traps of the Fire Caste.
But the Tau have not vanished. The Lamman Sept of the Tau Empire, the Fire Caste's hidden dagger, have come to grips with the slumbering giant looming over their doorstep and have moved forward into the final phases of their plan. Fleets ply the void, hunters stalk the orchards, and in the depths of the badlands a strange device is rapidly assembled for purposes unknown.
The Tau alone know that time is running out, and more than just the fate of Centaur III hangs in the balance.

SIGNIFICANT POSSIBILITY OF EXPLOSIONS.

This story is a sequel to Iron Hearts: Book 1 - Planetfall

An MLP/Warhammer 40K Crossover, part 2.

Celestia has handed down her order. The Iron Warriors must be defeated and driven from the planet, lest the corrosive grip of Chaos infect their world. With great reluctance, Twilight and Company depart for the Iron Warriors fortress-factory in order to confront the Chaos Warsmith. However, in this mission it is not the might of the enemy that will be their greatest challenge, but their own burgeoning friendships with the admittedly less-than-saintly members of the 38th Company.
At least until the Iron Warriors actually consider them a threat. Then it's totally their military might that will prove to be their greatest challenge.
All the while, the Tau forces lick their wounds and plot their next move. They are far from defeated, and the Iron Warriors have little inkling as to the aliens' true purpose.

MORE EXPLOSIONS!!

An MLP/Warhammer 40K Crossover

The Iron Warriors 38th Company has landed in Equestria, entrenching themselves like a barbed hook. They hunt the aliens of the Tau Empire, intent on destruction and pillage.
A small squad is dispatched on a reconnaissance mission, only to find that there is intelligent life on this world besides the feuding space-farers.
Will these improbably adorable and friendly equine aliens turn the damned warriors of Chaos from their blood-soaked path, cleansing them of their dark legacy with the magic of friendship and harmony?

No.
No, that isn't happening.
EXPLOSIONS!!

Most legends are born from a single small grain of truth, others are born from the pure imagination of a few ponies, but as Ponyville very well knows not all legends are that. When something saves Apple Bloom from a pack of Timberwolves will she be able to convince the others of what she saw or will she just have to find the truth herself?
