Equestria meets R.J. Macready

The two soldiers then began their trek in the Everfree Forest with more heavy weapons. As they were walking, Blake said to MacReady.

"You know it's not right?"

"What?"

"The creatures, they don't breed to spread, they infect others and spread by taking their forms, remember your squad and mine?"

"Yeah, I'm saying breed because they want to increase their numbers and that's in a way the basic way of it."

"I guess that's true but breed is for the terms of pregnancy and mating terms and those Things mostly use the cells of living and sentient organisms."

"Yeah but...hey what's that?"

The two saw a large helicopter and saw it crashed and with the troops all slaughtered with a large amounts of Thing creatures with dog like appearances and saw an insect like equine but she had holes in her hooves and green evil eyes and dark blue hair and insect wings inspecting one of the creatures that appeared to be dead and MacReady said with recognition.

"Hey, i saw her earlier, I don't know her though."

"Looks like she's been assimilated as well." Blake said

"Only one way to find out"

The two then jumped out and immidietly began to start firing their guns at the aliens mutated forms and as most were killed, more kept coming left-hand right. The large queen like bug equine said with rage.

"Who dares interrupt my hive?!"

"Look you crazy bitch, you have to go before those Things kill you!" MacReady said

"Quiet, these creatures have gave me new soldiers then my old one and you apes won't take that from me!"

"Run you idiot, theres a reason their doing that!" Blake warned

"Shut up, you-"

But at that moment, the creatures immidietly jumped at her all at once and killed the queen and formed her again, but this time Chrysalis instead had two large three fingered arms and a mutilated, open head.

"Shit, she's one of them now, get ready!" MacReady said

The now Chrysalis-Thing began to fight the two and as they did so Blake was the offense and fought her while MacReady defended him from the dog creatures all over the nest. As Blake lit the queen on fire, she screamed and roared with pain and as she burned, Blake said to her dead body in a rightful manner

"Hey, looks like your army is after a new meal!"

The creatures in turn turned away from MacReady as he used a flamethrower and he and Blake saw them eat the dead Chrysalis from head to toe and as this happened, Blake implanted a C4 on the helicopter and saw a large immobile creature on the choppers controls trying to absorb it, MacReady saw this and fired his shotgun and threw a grenade saying.

"Fuck you too!"

And at that moment, the chopper instantly blew up and caused a massive explosion all around the area, causing a bunch of flames and shrapnel to spread all over the area and kill the other creatures in the blast radius, even incinerating Chrysalis's body. The two managed to escape the area and saw the damaged aircraft giving a large smoke in the sky as they were leaving. As they left, they saw the remaining creatures and killed them off as well as they reached the forest, with MacReady killing some infected wildlife along the way. After a long, grueling walk to the exit of the forest, they saw the castle with guards all over the place and a barrier all around the two went to the guards who halted them and said

"State your business with the Princess"

"We have a report from the forest and the nest" Blake said

The guards let them inside and saw the Main 6, Spike, Starlight, the princess' s, Sunburst and Shining Armor in the room, Twilight went to them and asked

"What happened to you two?"

"We destroyed the nest, that way they can't kill, spread and assimilate here" MacReady answered

"Anything else"

"Yeah, we saw some female equine with bug like features blue hair, a small crown, green eyes and insect wings that was assimilated" Blake said

"That sounds like Queen Chrysalis" Starlight said

"Who?"

"Queen Chrysalis was the changeling queen, she feeds off of love and attacked us to do so in violent ways, she even did it at my wedding." Shining Armor said with disgust.

"And when she kidnapped us, she tried to kill Starlight, then her and our friend Thorax managed to change her army's view on love, but not her" Twilight continued.

"She must've been there to use the creatures to recreate an new army, that's why she must've tried to use the crash site as a nest before she was assimilated, she didn't know what it really was " Blake said

"That might also explain the pods that the creatures put in the chopper, they must be trying to find new organisms to assimilate, including the wildlife, Chrysalis and also like those dogs we encountered"

"Oh dear the poor things, you didn't have to kill them!" Fluttershy said with horror

"Yeah, we did kid, need I remind you they don't care who's who and all they want is to basically assimilate any organism until they get world domination?" MacReady said

"He's kinda got an point" Spike said

"By the way, what did we miss?" Blake asked

"Not much, me and the girls used that blood test needle you gave us and so far everybody was normal, we even saw a few creatures and me and Spike killed them, we did blood tests and we weren't infected by the cells."

"Ok, and just in case" Blake said and took a blood test needle and injected himself and put some in some vial in his bag in a med kit and MacReady did the same "Me and MacReady might have an immunity to the virus the creature caused and we can probably use it to make an antidote."

Blake handed her two, one with his name and one with MacReady's.

"Be careful, we need to make sure that whoever's infected may possibly be cured with a vaccine"

"Don't worry, I'll do what I can and inform you two"

"Good"

An awkward silence followed and Rarity said

"So what now?"

"How about you two stay" Twiligt offered

"Really?" MacReady said with astonishment

"Yes, but wait what are you good at"

"Well were both good in physical training but also in science when it comes to the creature, but how about a class when it comes to defense, I'll teach it" Blake offered

"I'll teach science and on some if the creature, it's power, strength, flaws and personality, and maybe teach with Blake."

"I'll see what I can do" Twilight said
