This story is a sequel to Metroid Equis

With the culmination of events on the BSL Research Station, Samus Aran is finally able to come back to Equestria, Planet Equis; to come back home. Much has changed in her absence, but it is still the friendly, peaceful, welcoming planet and nation that she left behind two and a half years prior. With the Space Pirate threat neutralized and the secret, illegal Metroid militarization programs destroyed, it appears that Samus can finally take another massive breather with her friends and enjoy some well-deserved rest, recovery, and relaxation. The galaxy is finally at peace.

At least... for a short while.

A new enemy, one much closer to home, soon rears its head, threatening all of Equestria and Equis with complete and utter annihilation. Their mission: revenge. Samus will fight with all of her being alongside her allies against an enemy who would like nothing more than to see all that she holds dear, including her home planet, completely razed. In so doing, her cunning, ever determined enemies unleash a weapon so unexpected, so eerily familiar yet horrifically foreign that even Samus herself just might prefer the late Ridley or the SA-X...

Canon Considerations
MLP-FiM: Up to AND including "Magical Mystery Cure." (Seasons 1, 2, and 3)
Metroid Series: Everything up to AND including Metroid Fusion (Including original mangas. See official timeline above). So, effectively everything.

A Metroid Crossover

A meteor, resistant to magical manipulation, crashes in Equestria, Planet Equis, and soon spreads an unknown poison throughout the land. Containment is all but failing and the Princesses have little power to stop the spread of the Great Poison. The Elements of Harmony are of little use as no knowledge exists of this threat that consumes all life. Help comes from a certain Hunter, clad in metal.

Samus Aran will not only fight for her life as always, but her own sanity as well as these ponies that she begrudgingly starts seeing as allies. New horrors and abilities await her as a reason to fight slowly festers within her, possibly unlocking something she had been denied for so long: Friendship.

Notes and Resources:

This takes place after Echoes. The events of Corruption will have not happened yet. In terms of MLP, consider everything up to and including the Crystal Empire. Princess Twilight does not exist here, etc. The official Metroid Timeline can be found here.

As well, this story references the manga in many places. Reading of it is not required and I try my best to explain the context, but if you're interested, both volumes can be found here.

EDIT: This story was written over two and a half years, beginning in 2013. You'll probably notice the difference in writing as the chapters progress.

Big Daddies: The ultimate protector of the metal city of Rapture, guardians to the Little Sisters. For years they patrolled the underwater streets of the distopia, keeping their little ones safe. But with the fall of Rapture and the death of almost all of the Big Daddies, where does one go from there? To the land of Equestria, where peace and Harmony reign. Does this peaceful land need a silent protector? And can the Big Daddy find a place to call home?

A few quickies: Little Sister's word is law. The Big Daddy will also be a bit more like the Alphas, but that will be explained later. You might be a little lost if you haven't read the other stories, but only for a certain character.

Hoping to find a cure to a rare disease that has been tormenting her since she was a filly, Octavia Melody travels to the ancient city of Yharnaram, said to hold a magical remedy powerful enough to heal any illness. Instead, she discovers a metropolis spun into a web of eldritch terrors eager to devour anypony who enters its gates, and, perhaps now that they have found the one they are looking for, the world itself.

-----------
This story was born out of my frustration at being incapable of writing a anything worth reading, and is going to be mostly unedited and unplanned. If that doesn't scare you off, then prepare for a tale "told by an idiot, full of sound and fury".

(Knowledge of the game Bloodborne is not required to enjoy this fic.)

Equestria is dying.

There is nothing anyone can do about this.

The sun has shined too long. The Age of Sunlight must come to an end. But Celestia refuses to let it extinguish, and the land is shrouded in everlasting dusk. And now, among the living, are seen bearers of the accursed Darksign. Those doomed to die, again and again, until their minds fade away and they turn hollow, forever seeking the souls of others for nourishment, in a futile attempt to regain their lost memories and lives. But there is now only one way for their suffering to end. Celestia must be slain, so that the Age of Dark may take its natural turn.

'Dark Souls' crossover.

An interlude between Flammenwerfer's fics Metroid: Equis and its sequel, Metroid Equis II: Duality.

The war is over. Equis has survived the dual threats of Phazon and Space Pirate invasion. A new era of peace and prosperity covers the planet, as new trade routes between Equis and the Federation - centered in the country of Equestria - bring new technology and wealth to the nation, and the world.

But these thoughts are far from Fluttershy's mind. Her thoughts are focused on her friends - especially Samus, far distant from the world - her daily life, and her animals.

In particular, a new one... One she's never seen before. But she calls Fluttershy Mama, so of course she'll care for the little flying jellyfish, whatever she is.

What could go wrong?

Edit: It isn't required to read Metroid: Equis to enjoy this story...but it's highly recommended to read it anyway. It's a really good story.

Dead.

It all happened so fast. One minute they were there, and the next she was standing in their ashes.

Lost forever.

It wasn't fair. They’d devoted their entire lives to defending Equestria, and what was their reward? To be cut down in the blink of an eye. Weren't they supposed to be the heroes? Weren't they the good guys, the chosen ones, the saviors of the land? This wasn’t the way things were supposed to go!

Alone.

Twilight wouldn't accept it. No, she couldn't accept it. How could fate be so cruel? Why did she have to be the only one left alive? Why did she have to suffer on with such a terrible burden, reliving that terrible moment again and again for all eternity? No, regardless of what anyone said or did, she knew that a terrible mistake had been made, and she would see it fixed...

...no matter what the cost.

'Dark Souls' crossover. You do NOT need to play the game to enjoy the story.

Scales hold a lot of meaning to dragons: protection, life, social status, breeding, normality; all are qualities that any living being with a conscience thrives upon.

Seath the Scaleless is deemed an abomination by his entire race. Out of jealousy and hate, he betrays them in a war that wipes them out. And after centuries of trying to replicate scales through means of crystal, he is finally slain. But this wasn't the end for Seath the Scaleless, for in a land where time is convoluted, with heroes centuries old phasing in and out, he is given the chance to begin again.

He's reincarnated, near-death and mortally wounded, in the backyard of a timid little equestrian named Fluttershy. Seeing as he has nowhere else to go, she takes the abomination under her wing. As time passes, she quickly warms up to the dragon and embraces him with the alien concept of "kindness." But after centuries of the world and himself seeing only a monster, will it be enough?
