Equestria meets R.J. Macready

After the ordeal, MacReady and the royals had went inside and along them came both the other 5 and Spike, Starlight, Sunburst and surprisingly the Pillars led by Starswirl. Twilight told Starlight and the others but Spike to stay out as MacReady spoke to them. When they reached Twilight's office, Princess Celestia then said and introduced herself

"I don't think we have been properly introduced, my name is Princess Celestia the Sun Princess, there is my sister Princess Luna, the Night Princess."

Shining Armor said "I am Prince Shining Armor of the Crystal Empire, this is my wife Princess Cadance and my daughter Flurry Heart."

Twilight said "I am Princess Twilight, the Princess of Friendship"

MacReady gave an look of utter bafflement, but rolled with it and Pinkie suddenly appeared

"HIIMPINKIEPIEWHATSYOURSDOYOULIKEPARTIESWHATSPECIESAREYOUAREYOUFROMANOTHERTOWN-"

Twilight immidietly out her hoof in her mouth and cut Pinkie off and MacReady gave a look of confusion.

"Don't ask" said Twilight

"Ah'm Applejack, one of the owners of Sweet Apple Acres and the best apples in Ponyville" Applejack said

"A pleasure to make your acquaintance darling, I'm Rarity, owner Carousel Boutique."

"I'm the one and only Rainbow Dash , the fastest flyer of all time and soon to be Wonderbolt"

"I...I'm Fluttershy"

"I'm Spike, Princess Twilight's No.1 assistant"

"My name is R.J., I'm a helicopter pilot for the U.S army that basically is a group that fights to protect from bigger threats then others like this one."

"Well, with that settled, may we ask as to what you and that thing are?" Celestia said

"Me, I'm a human and for that Thing, I can't really say much from having the ability to imitate or shapeshift."

"Why?"

"Because I don't know what it is either, but what I can tell you is to butt out to keep you safe"

"You will treat the Princess with respect creature!" A guard said poking MacReady with his spear and MacReady immidietly pointed his flamethrower at him and said menacingly.

"Hey horseshit, poke me again and I'll bbq your ass for dinner like that other fuckface guard I encountered!" This caused the guard to give a frightened look, causing the other guards to take aim.

"Stand down!" Celestia said

"But Princess, he.."

"Stand...down" she said firmly

The guards stood down and lowered their spears and MacReady lowered his weapon, but then flicked the guard to ground with amusement, much to the guards dismay.

"Now back to the matter, why can't we help?"

"Because, if that Thing kills you, it'll steal your power, form and imitate you in order to breed more offspring."

"Yes but these are my subjects being threatened, I must help."

"Too bad, the last thing I'm pretty sure we all need is for that Thing is not only gaining your-"

A knock on the door was heard and Twilight said

"Who is it?"

"A friend of MacReady"

Twilight, although reluctant, complied and opened the door and an all too familiar figure came in.

"Blake?" MacReady said in awe

"MacReady?, how'd you come in here?"

How these two had met?, during Blake's infiltration in the Antarctica camp, he too encountered the creature and had to kill them all as well as his own teammates one by one due to the Thing assimilating them. These two teamed up to kill Colonel Whitley, who wanted to use the creature to produce bioweapons and injected himself with its blood, turning him into a monster. Luckily, with the help of MacReady, they both managed to kill the mutated Whitley.

"No clue, you?"

"Same, but bad news.."

MacReady cut him off "Let me guess, that Thing is here?"

"How'd you know?"

""I had to kill some on the forest, by the way was there anybody else with you?"

"No, only that Thing that killed off some wildlife in the crash site"

"Crash site?" MacReady said

"While I was falling in the forest, for some reason I saw a crashed chopper near and get this, it was from Whitley's men."

"Ok, I can't take it, what are you two talking about?!" Rainbow Dash said

"You know how I said I'm with the army?"

"Yeah?"

"So was he and it turns out that his superior wanted to use the creature and it's power in order to create more weapons and possibly also because he wants to cure his cancer" MacReady answered

"Not only that, but the helicopter crash ended up causing some of the creatures to use it as some sort of nest so that way they can use it to prepare for breeding and increasing their offspring by assimilation. Just like it did to the ones onboard." Blake added

"Wait, hold on, what's a helicopter?" Twilight asked

"Its a flying machine that works by gas and engines that help it go up and the large sharp propellers help it increase the altitude"

"Wait...does this "helicopter" look black and have some guys in black suits?" Spike asked

"Yes why?" Blake said

"Oh no, that might explain what i saw earlier, that's why those creatures attacked, we were near their nest!"

"What?!, do you know where?" Blake said

"So do I, I put a tracker in their location, when I killed some of them." MacReady revealed an GPS

"Ok, you all stay here, we'll deal with the creature and get rid if the nest."

"No!, we can help convince it and..." Twilight said, but Rainbow cut her off

"Twilight, no offense but I don't think those Things care, in fact you remember what happened" Rainbow Dash pointed out

"Yeah, plus one of them almost killed us until MacReady came" Spike added

"But" Twilight said

"Look kid, we know you want the peaceful way, but sometimes in times like this, that's not always the way things will always work" Blake said

"Yeah, plus if you were assimilated back there, I don't think you would come back from that" MacReady said

Twilight however stood firm but immidietly backed down upon seeing the two humans aim their weapons at her causing the other ponies to get ready to fight, but they stopped when the GPS said

"Location traced go North"

"Look, your all staying and that's final, Capiche!?" Blake shouted, now more dead serious

"...fine" Twilight complied

"Plus if if makes you feel better, you can use this"

"A needle?"

"No, it's a blood test hypo, you use it to text blood to see if the person is really that person or a fake imitation from the creature."

"...ok"

"Thanks, and by the way, I need another thing..Spike?" MacReady said

"Yes?"

"Stay protected at all times, your fire breath is an emergency power we can use since the creatures hate flammable related material"

"Ok"
