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.

The Changelings are growing in power. The Elements are losing power. When a strange event leaves Equestria with a potential replacement for one of the Elements, they must get around one small detail. This replacement? He's not local, if you catch my drift.

This is a crossover between MLP and the Megaman/Rockman franchise starring Zero and the Cyber Elf from Megaman Zero 4.

Twilight Sparkle has too much magic, and it will take her decades to learn to control it. Her spectacular loss of control during her entrance exam only proves that fact. She is a danger to herself and others.

After Sunset Shimmer’s disappearance, Princess Celestia needs a new student to bear The Element of Magic to defeat Nightmare Moon. With all of Equestria at stake, Twilight Sparkle…is not the pony she needs.

Princess Celestia seals Twilight Sparkle’s magic with the distant promise of one day teaching her.

But there are two diarchs of Equestria. Amidst a lucid dream, an offer is made.

“Hello, Twilight. Would you like to be my student?”

This story is a sequel to Stardust

Times are changing for Equestria as Twilight’s return brings with it news of people and cultures from beyond the peaceful world everypony knows. Aid and volunteers are freely offered to help the besieged humans of Earth because every Equestrian knows that’s what good friends do. Unfortunately, making friends can also have the unintended consequence of making enemies.

When the monsters besieging the humans strike at Equestria with a level of brutality not seen in over a thousand years, the cry for help is sent to all the kingdoms of the world. Honored allies step forth to fulfill ancient treaties and oaths. Enemies, old and new, bury their grievances. An alliance never before seen in Equestria will be created to combat the monsters from the void.

And because of these events, a grim but welcome sibling to the XCOM project is born.

Isolated from her friends and taken prisoner in the middle of a war, Twilight must deal with the very real dangers of being percieved as an enemy as well as the nightmares of her arrival on 'Earth'. Can she overcome her own fears and the fears of her captors? Will the wayward unicorn's assistance be a boon or a curse to the 'humans?' Most importantly, will she ever find her way home?

"In short, it's a story of friendship and plasma rifles, with the emphasis on the friendship. The characters are well written, the XCOM setting is fleshed out very well, and the story is compelling. If you love XCOM, you'll love the story, but even if you've never heard of it, it's more than worth giving the first 3 chapters a read.

There's excellent action later on, but the real strength lies in the collision between the friendly and naive world of Twilight Sparkle and the desperate world of humans fighting a losing war for survival and willing to do anything to turn the tide."

When Luna gifts Twilight the town of Ponyville and its surrounding countryside as her demesne she's initially confused. Then, after double checking her dictionary, more than a little concerned.

All her friends are, legally, her possessions. The town that took her in is her plaything, if she so wishes. She has been given responsibility.

Can Twilight's vision for a modern renaissance outrun the harsh realities of the shadowy figures pulling strings behind the scenes, nobles jockeying for her attention, and an irritatingly metaphorical love triangle?

Special thanks to the insatiable Blue_Paladin42, the incorrigible Maskedferret, the intuitive Southpaw and the indestructible newbiedoodle for all their hard work, past, present and future.

Starburst, the daughter of Princess Twilight Sparkle and Prince Flash Sentry, has about all she could ask from life: loving parents, her Little Brother Best Friend Forever, and despite her seriousness and disciplined mentality, she has group of friends close as family. She also has an ambitious goal in life: she wants to be the first mare ever to become the Captain of the Royal Guard, which she's been preparing herself for since she was a little filly.

So... what would happen if she were to meet a pony that is an exact opposite of her?
