Master Chief: Protector of Equestria

Chief holstered his pistol and nodded at Eyan. Eyan placed his plasma pistol on its magnetic holster.

“Fluttershy,” that word felt weird coming out of Eyan’s mouth. “What planet are me and my friend on?” Eyan asked.

Fluttershy whimpered and said, “I d-don’t know, you’ll have to ask my f-friend, Twilight S-Sparkle.”

“Can you take us to this ‘Twilight Sparkle’, Fluttershy?” Eyan asked in an even softer tone.

“That won’t be necessary, Fluttershy,” A motherly voice said behind Chief and Eyan. “I have Twilight Sparkle right here beside me.”

Chief looked over his shoulder to see a tall, white horse with a long, pointed horn and large wings. Next to the white horse was a shorter, purplish horse with the same traits.

“Ah, I was wondering the exact time in which you would arrive, John-117. I see you brought a friend, too . . . Good. I am Princess Celestia, and this is my student, Princess Twilight Sparkle.” Celestia said, pointing her hoof at herself, then at Princess Sparkle.

“It’s an honor to meet you Master Chief Petty Officer John-117,” Twilight Sparkle says, barely holding off a squeal of excitement.

“How do you know me?” Chief asks, grabbing the DMR from the magnetic holster on his back and holding it so it can be brought to the ready position quickly if necessary.

“Please put that . . . thing . . . away, Chief. we’ve seen what you’ve done with the things you call guns” Celestia says.

Chief replaces the gun on his back.

“You haven’t answered my question.” Chief notes.

“We have our methods, Chief. Now, if you and your friend place your hands on my back, we’ll take you to the Castle where we can explain easier . . . and safer.” Celestia says. Chief does so, and Eyan steps forward and places his hand on her back too.

The trio appear in the castle with a ‘pop’. Twilight appears shortly after with Fluttershy by her side.

“I’m going to go get the rest of the Elements.” Twilight says, then she disappears again.

Chief turns to Celestia, who had sat down on her throne.

“First thing’s first, what planet and system are we on?” Eyan asked.

“You are on the planet of Equis, fifth planet from the sun in the system Equoria. The country you are in is the country of Equestria. To the north, The Crystal Kingdom and the Frozen North. To the East, the Great East Sea and Griffonia beyond that. To the West, the Great West Sea. To the Southeast, Dragonia. All other land is Equestria” Celestia said, laying out a map of the country of Equestria.

(here is the map i just described, and the map celestia laid out)

“Good morning, Celestia. What’d I miss?” a voice in it’s mid-twenties asks. Chief turns around to see Noble Six of Noble Team, which fought on planet Reach.

-insert your ‘Halo: Reach’ Noble Six appearance here-

“You’re Noble Six?” chief said.

Noble Six folded his arms over his chest. “You’re the Master Chief?” Six asked in reply.

“Do you remember the AI you delivered? She’s right here.” Chief said. He lifted his hand to shoulder level, palm up.

Cortana appears in Chief’s palm, the first and only AI generated from living tissue. She flickers and flashes red twice, then returns to normal.

“Chief, now there is no way we can save me from rampancy, now that Doctor Halsey is so far away. I don't even know where we are. It’s outside my knowledge base.” Cortana sighs. She disappears from Chief’s hand, and he lowers it.

“Oh you don’t need to worry about that. Princesses Celestia and Luna tell me they have been brainstorming ever since Cortana was created on Reach. They have a solution, but it’s an unlikely solution at best.” Six said.

“Excuse me, but where do I come into this?” Eyan asked.

“Ah yes, the defector of Requiem. There is always at least one defector per planet when the covenant fights humans on their own settlements. The arbiter is a perfect example. Now, how you are important. . . Oh yes, you are to fight by Chief’s side in an upcoming war.” Celestia said.

"exactly how long have you been watching the Human-Covenant war?" Chief asked Celestia.

"Ever since the first covenant landed on Harvest, Spartan," Celestia replied. Chief turned to Six

“Why don’t you fight with us, Six?” Chief asked.

“I gave up my gun for the ponies to research it for the mass production of ammunition for when you were to arrive, and they recreated my armor, tested its capabilities, and modified the hell out of it. If you try to break through my armor with a sniper rifle round, I don't even feel the impact, let alone have it damage my shield much.”

“What's the catch about this upgrade?” Chief asks.

“The weakness of our shields is magic, primarily electric magic,” Six says. “But really all magic in general.”

“Magic? How is that possible?” Eyan asks. Everyone ignores him.

“The good news?” Chief asks.

“The metal part of our armor can be reinforced with crystals that have magic-collecting abilities,” six replies, “making our inner metal armor a magical weapon to be deployed when you will it to be deployed. as a demonstration, i will ask celestia to charge me with electricity when i disable my shields”

Six’s shields turn off and Celestia’s horn lights up, making a large bolt of electricity hit Six’s armor. The electricity crackles and snaps as it is absorbed into a greenish-yellow crystal above the shield generator that Chief and Eyan didn't notice earlier.

“Open the window” Six says.

Celestia opens the window with magic, and Six points his hand out the window.
