It has been several months since the disappearance of Twilight Sparkle..

One night, after watching her sister raise the Moon and set the heavens alight, Princess Celestia begins to bed down for the night, only to be interrupted by portal forming in her room. From out of the portal comes none other than Twilight Sparkle, garbed in strange armor.

Princess Celestia, along with Luna, Cadence, and Shining Armor, are overjoyed by the Element of Magic's return, but are justifiably curious as to where she had been and what she had been doing. And so, Twilight begins her tale. A tale of survival against impossible odds. A tale of a people fighting for the most basic right of all sentient beings. The right to exist.

When a supposedly-Forerunner artifact activates on-board the UNSC Guam, turning everyone on board into ponies, It sets in motion a clash of forces, ideals, and dimensions that could save humanity in its darkest hour, or doom the peaceful land of Equestria to burn in a war never meant for them.

This story starts some time before the season 2 finale, but after the other episodes of season two. Season 3 stuff will only be used if I find a reason for it/don't think it's OP (I'm looking at you Twilicorn and Mirror Pool.)
This story also takes place before Halo: Reach, so don't expect things to stick very close to the games.

Minimalistic cover art was made by me in Microsoft Paint, because I have buck-all else to work with.

Character tags will be added as they become major players.

A Jinouga (of the Monster Hunter series), named Raiju, is chased from his homeland thousands of miles from Equestria after his king discovered him sabotaging their army and ordered his execution. After catching wind of this he makes his escape, and after weeks of running, and taking a serious blows, leaving him with a gaping wound and a broken foreleg. Continued running on his injuries leaves him with no other options, he began charging up a massive amount of electricity to teleport himself as far away as possible. He did not know where he was or where he was going, but he knew that it was his only choice. Now completely drained of energy he awaits his death, until he is saved by Twilight Sparkle. He begins his healing process in secrecy, until Princess Celestia catches wind of his existence in Equestria and orders his capture and execution. This execution fails and eventually the princess allows him to stay in Equestria for a while longer while he heals from his injuries.

A One Piece / My Little Pony: Friendship is Magic Crossover.
This story, is a re-telling of the G1 MLP pilot episode "Rescue at Midnight Castle" with G4 ponies, several G1 MLP villains not in the original pilot, and Tony Tony Chopper from One Piece replacing Megan's role.
Takes place after the royal wedding, and before Season 3 for MLP
Also takes place after the Straw Hat's Fishman Island adventure, but before reaching Punk Hazard.
(Warning, some light Chopper X Fluttershy crossover shipping)

During one of the Straw Hat Pirate's voyages after the events of Fishman Island, a storm of the New World strikes their ship, The Thousand Sunny, and sweeps Tony Tony Chopper, the crew's reindeer doctor, overboard. He later awakens in the cottage of a yellow winged pony named Fluttershy who rescued him. Chopper discovers he's in a land called Equestria.
Little do any of the know, ancient evils long forgotten over time, threaten to plunge the land into darkness.

After an accident with the Kanohi Olmak, Takanuva finds himself stranded in a new dimension and stuck in a new form. With no way to get home to his own universe, he has resigned himself to living out a peaceful existence in his new home, but his past will soon catch up to him in a way that could be disastrous for not just his world, but for all of them.

The storm is breaking on the Horizon.

It's been two months since the battle against Nightmare Moon. Luna is recovering, Celestia is busy turning the government back into a diarchy, and the Mane Six have returned to their lives. All seems well, but when Celestia discovers that half of the power of the Elements of Harmony have been transferred to each of the Bearers, she decides to send thirteen mysterious members of the Royal Guard to monitor them as they manifest and develop their new abilities.

The sins of a forgotten war still linger, and an ancient evil lurks in the shadows, just waiting for the right time to strike. The Mane Six suddenly find themselves once again at the heart of a conspiracy to bring about Eternal Night, and only by awakening their powers and realizing their full potential can they do anything to stop it. Friends both old and new will help them along the way, and an unseen force will guide them as it seeks to right a wrong made thousands of years ago. The Bearer's journeys will take them outside the borders of Equestria and into the world beyond, and when they return, they'll have the power and experience necessary to save the world and bring about balance in all things.

Thanks to Wildy71090 for the cover pic.

After her humiliating defeat at the hooves of Princess Cadence and Shining Armor, Queen Chrysalis and a small cadre of her Changeling minions find themselves lost on a lonely mountain deep in the Everfree Forest. With a storm brewing, she decides to take shelter in a cave along the Mountainside.

Unfortunately, the cave is already occupied. Queen Chrysalis and her forces are swiftly surrounded by the Predacons. However, before hostilities commence, Megatron makes her an offer. An offer she would be an idiot to refuse.

Sequel to "My Little Pony: Flesh and Steel", which can be found here

It is the year 2552 and the Pillar Of Autumn has just entered Slip space to escape the Covenant fleet at Reach. A malfunction occurs with the Slip space drive and sends the Autumn and her crew into unknown space. The first planet that comes into range is very Earth like, and is giving off intelligent life signatures. What they don't know is that their only way back home is on this planet. The Autumn dispatches a scout party and what they report back is unbelievable. A world completely inhabited by ponies, millions of them..... Welcome to Halo: Equestria.

I'll add in more character tags as they are introduced in the story.
