Spartans never die, they're just missing in action. This has never been more true for Jorge-052 as, after activating the slipspace drive that was supposed to kill him, he is instead flung into a strange world where war is but a distant memory. Will the aging soldier be able to adapt to this new peaceful planet? Or will his only salvation be found in finding a way back to his own chaotic universe?

(It's my first time, so be gentle)

There is a world where Life and Death govern all imaginable realms. A world where Watchers guard over their planets and the creatures that roam them. In this world, a young soul goes on a journey to a place he never thought existed, after cutting an untold deal with Death.

Equestria, a place of magical creatures and mysteries, offers him a new chance at life. A chance he will have to pay dearly for. This is the written story of his adventures, some of the sorrows and victories of his life as he goes through great challenges and fights his inner darkness.

At the end of this journey, one begs the question: What is better? To be born good, or to overcome your evil side through great effort and sacrifice?

2nd POV. You are depressed, your life seems to be one tragedy after another as you are transferred from orphanages and foster homes. You've almost given up hope until you die. You've been given a second chance at happieness and now you must come to terms with your past and your present.

There is a legend. A legend of six heroes destined to protect Equestria from danger. But these six are not the Elements of Harmony. They are more.

The Steadfast Commander.
The True Genius.
The Vigilant Eye.
The Merciless Wrath.
The Fighting Spirit.
The Lone Wolf.

They are the true Protectors of Equestria.
They are the Guardians.
They are Noble.

Alright, so here is the story I have teased on my blog, The Noble Guardians! If you already guessed the concept, good for you! But for the rest of you, this is a Halo: Reach Crossover. I have seen a couple fics in which Six or Jorge are brought to Equestria, but they were always alone, so I decided to bring them all together as one. This will follow the show's storyline, with Noble acting as additional characters to the episodes, but don't worry, I guarantee they will be major characters with their own arcs and there will be plenty of original situations. I will also most likely skip any episodes in which Noble would have little to no involvement. (This will be few and far between, one example being "Call of the Cutie" I mean, even the Mane Six are only minor characters in that episode. I'll probably either mention those in passing or have another story going on with those episodes occurring in the background.) Anyway, see how Noble reacts to becoming Equestria's destined protectors!

Naturally, this story contains spoilers for Halo: Reach

2 of the most skilled pilots are sucked into Equestria. Upon landing they are greeted with mixed emotions. It's obvious that they aren't suppose to be here, but something, or someone has brought them here. It's certain that what brought them to Equestria was no accident. Now they must find out who brought them, and "Kindly" ask that pony to send them back.

After a smash and grab mission goes haywire, the Master Chief finds himself in Equestria. As he meets the ponies we all know and love, his past with Cortana haunts him as he struggles with his new life.

But a threat who wants revenge makes their move . Will John 117 move on from the past to face the enemy, or will he not care and doom the ponies to their fate?

In the pony timeline, this takes place after Tirek is defeated. In the Halo timeline, it takes place after Halo 4 and before the events of Halo 5.

Edit 1: Changed the rating from mature to teen. Tell me if I should keep it the same.

A whole year has gone by since Princess Cadance and Shining Armor adopted Nathan, for he is now 6 years old and has adjusted to his new life in Equestria, but now a bigger joy comes into his life when he learns that he is going to be a big brother soon, but when the baby finally arrives it's not as much fun as he thought.

After an argument with Rainbow Dash about the romance plot in the latest Daring Do issue, Twilight Sparkle constructs a machine that allows two ponies to enter a novel, in order to learn more about Rainbow's obsession with pairing Daring Do with her bookish sidekick Rosetta.

Soon, the two find themselves in a Daring Do adventure, with Rainbow taking the name part and Twilight playing Rosetta. As they deal with ancient jungle ruins, mythical artifacts and old adversaries, Twilight is starting to see the appeal of the pairing.

But after all, it is all just fiction, and what happens in a novel has little to do with the real world, right?

Written for the TwiDash Group's Abandoned Fic Challenge.

Rated Teen for some violence, some very tame makeouts, and a slightly inebriated pony.

You've watched every episode at least twice. You make regular pilgrimages to Hot Topic for pony stuff. You post regularly on MLP fanfiction sites. And you have a crush on Fluttershy.

In short, you could not be more of a brony if you tried.

So what happens when the Mane 6 suddenly materialize in your bedroom...and they're not very happy to see you?
