At Castle of Friendship, Twilight is cleaning Spike up while Elements of Harmony are trying to figure out about Rarity’s sudden appearance.

“Hey Spike, I want to apologize for almost killing you.... I didn’t meant too!” Twilight apologizes to Spike

“It’s okay, you were possessed by a demon” Spike smiles at Twilight and he looked at Elements of Harmony, “Now, Rarity is possessed by a demon and I won’t stand of this!”

The revelation of a possessed demon confuses Elements of Harmony.

“Ya telling me that Rarity is possessed by a demon?” Applejack asked Spike in a confused tone

“A demon?! Are you like for real?!” Rainbow Dash asked

“Yes! Before Rarity get possessed, I saw his spirit coming after her” Spike explains to Elements of Harmony who are flabbergasted about this.

“You saw his spirit? How come none of us able to see his spirit?” Fluttershy asked

“That because only Dragons can see his spirits” came a voice.

Spike and Elements of Harmony turn around to find Ember and some of the dragons including Garble of all people standing in front of them.

“Ember?! Where did you come from?!” Spike asked his good dragon friend as he embraces Ember and she returns the embrace.

“Never mind that, the most important thing right now is we must stop Jack Possessive from throwing Equestria into madness at once!” Ember slamming her claw to the table.

“Who is this Jack Possessive?” Twilight asked

Ember look at Elements of Harmony as she tell them about Jack Possessive.

“Jack Possessive came from a family of demons that can possessed any creatures and his father, Frank Possessive is my dad’s mortal enemy as he constantly trying to throw Dragon Lands into madness and he absolutely despised the Possessive family! We dragons are the only one who are immune to their possessing powers as we have more stronger wills and we are more hardened then any creatures!”

Spike realizes something, “That explains why Jack was unable to possess me!”

“So what happened to his father?” Twilight asked Ember.

“Eventually, his father’s arrogance caught up to him as he tries to possess my father but he prove too strong for him to possess and he was defeated by him. My dad hated him so much that he banished him to the another universe so he wouldn’t cause any problem for Dragon Lands anymore.”

“I don’t get it! Why did he tries to possess me even through Dragons are immune to his possession power?” Spike asked

“Well, it seem Jack is like his father, an arrogant jerk who are full of themselves” Ember gives her answer on Jack.

Spike look at Garble who is looking away from Spike, “Why are you here, Garble?” Spike growls at him, “Are you up to no good?”

“Listen Sparkle-warkle, the two reason I here; one, I was forced by my Dragon Lord to help her of hunting down Jack Possessive and two, I might be not fan of ponies but i will only help you once because if that demon lays one finger on my sister” Garble pounding his claw together, “I will shred every part of him!”

“You have a sister?” Spike asked Garble

“Garble, please calm yourself down. I’m sure Jack won’t be able to possess your sister” Ember reassures Garble

Garble look at Spike and Elements of Harmony

“Consider this a temporary truce..... for now” Garble making an Enemy Mine with them despite doesn’t like ponies and especially Spike. Spike and the rest of Elements of Harmony glares at Garble.

“Come on, guys! We are going on the hunt!” Ember announced to Spike, Elements of Harmony, Garble and rest of the other dragons, Ember approached to Spike, “Tell me, Spike. Who was the last creature that Jack possessed?” Ember asked Spike.

“Rarity! He’s possessing my Rarity!” Spike yells in a concern tone as he worried about what’s Jack is doing to Rarity.

At Carousel Boutique, ‘Rarity’ looking at all the dresses she made as she touch one of her dresses she made for a client who is waiting for it.

“I didn’t know this pony have a huge obsession with dresses! Well, sorry to disappoint you Rarity but I going to have a fun time of ruining your dresses. He he he he he he he!” ‘Rarity’ chuckles as she grabs the dress and ripping her dress apart, “Oops! Aw, I’m sorry that I rip your dress that you made for a client..... NOT!” ‘Rarity’ throw the dress like it was a trash to her, “What is the better way of shredding those dresses than an irony music!” The music start playing as ‘Rarity’ proceeds of ruining all of her dresses.

‘Rarity’ use her magic to break all of her mirrors while knocking down all of her dress form mannequin and movable screens.

“Score!” ‘Rarity’ jump on a small display stage and dancing on it while using her magic to destroy all of her dresses, “This is exciting!” ‘Rarity’ looks around as she see her destroyed dresses to resemble like a falling snow and she land on the ground and pretend to making a snow angel, “Poor Rarity, I destroy all of her dresses and I should feel bad for her.... NOT! I means why would I feel bad for ruining someone else’s dresses? Making dresses are such a waste of time! He he he he he he he he he he!”

She continues to having a fun until she notices her mane and got an idea as she grabs a pair of scissors and planning to cut all of her manes.

“For a beautiful unicorn like you, it’s such a waste to cut all of your beautiful mane...... NOT! I just thought it would be funny to have yourself cut all of your beautiful mane! That dragon will never fall in love with you without your beautiful mane! He he he he he he he he he he he!” ‘Rarity’ give out an evil laugh as she about to cut all of her manes until her hoofs was blasted causing her to let go fo the scissors, “Ouch!”, she turn around and saw a pissed-off Spike, Elements of Harmony, Ember and the rest of dragons standing in front of her.

“Now, you have gone too far! Jack Possessive! First, Twilight and now Rarity?! You ain’t cutting my Rarity’s mane! Let go of my Rarity!” Spike growled at Jack Possessive in Rarity’s body as he stomping toward him looking as mad as hell.

“Aw, this little dragon want his precious unicorn back..... well...... TOO BAD! you can’t have your precious Rarity back as long as I possess her!” Jack burst into a hysterical laugh at Spike who is clenching his claw in fury.

“Jack Possessive! You are causing enough trouble for Equestria” Ember glares at Jack Possessive.

“Yeah! Let go of our friend!” Rainbow Dash yells at Jack

“Why end the party so soon? It just got starting and I don’t want to end this spectacular party!” Jack continues to laugh at the heroes.

“Oh, this is not that kind of party I want to attend” Pinkie’s mane become deflated as she sobbing.

“Look what you did! You made her cry, you varmint!” Applejack angrily yells at Jack.

“As much I love possessing this body, I am getting bored” Jack is out of Rarity’s body as Spike manages to catch Rarity before she hit the ground.

“Gotcha, Rarity!”

“Garble! Grab him!” Ember ordered Garble to catch Jack, Garble and rest of dragons attempts to tackle him but Jack dodges them and Garble & the rest of dragons hit on bunch of Rarity’s supplies as Jack went into Applejack’s body.

“AAAARRRRRRRGGGGGGGGHHHHHHH!” Applejack become possessed by Jack as her Bright Green eyes turned into a Red eyes.

“Oh dear” Fluttershy quickly get behind Rainbow Dash

“Yee-Haw! Now I feel like a cowboy! Alright, Bad hoss! I’m not goin’ to waste your bobbery! I got a hoe-down!” Jack use his demon power to transport himself in Applejack’s body out of their sight. Elements of Harmony especially Twilight are flabbergasted.

“When did Applejack suddenly can transport herself?” Twilight asked

Ember facepalm herself at Garble’s failure, “You had one job..... ONE JOB, GARBLE!” Ember angrily yells at Garble.

“It’s not my fault! He was too fast for me to catch!” Garble defend himself which Ember frowned at him.

Spike looks at a sleeping Rarity who is no longer possessed by Jack, “Rarity, please wake up” he pleaded.

Rarity opens her eyes and she’s groaning, “What a terrible nightmare I have” Rarity muttered to herself before she see Spike who is holding her body and she envisioning Spike as her Prince Charming, “Spikey-Wikey?”

“Oh, Rarity! You back!” Spike embraced Rarity as he’s glad to have his Rarity back, Rarity returned the embrace.

“Spike! I had an awful dream! There was a demon and he was ruining all of dresses whiling he was planning to cut all of my mane and...” Rarity looked around and see her workroom in state of disrepair which made her eyes twitch. Spike and Elements of Harmony chuckled sheepishly while Ember remained calm and Garble rolls his eyes.

“Rarity..... please.... calm down” Spike trying to calm down Rarity whose face turned red and her eyes look like a volcano.

Pinkie Pie whose mane went back to it’s usual style looked at you and says, “3, 2, 1”

“AAAAAAAAAAAHHHHHHHHHHHHH!!!!!!!!!” Rarity screams so loud that it cause Ponyville to have a temporary earthquake.

‘Applejack’ arrives at Sweet Apple Acres.

“Sweet Apple Acres? I bet this is the cowgirl’s home..... Why am I talkin’ like a hillbilly?” ‘Applejack’ asked herself before she see Apple Bloom and Big Mac walking toward them.

“Applejack! I thought you were at Castle of Friendship.” Apple Bloom and Big Mac are unaware that their sister is possessed by Jack.

“What happened?” Big Mac asked his possessed sister

“Well, isn’t my favorite cowboy and cowgirl!” ‘Applejack’ gives a big grin to them which disturb both Apple Bloom and Big Mac before she punch Big Mac’s crotch.

“Ow!” Big Mac scream in pain while ‘Applejack’ laugh at him, “Bless his heart, he is dumb as a sack of rocks! He he he he he he he he!” ‘Applejack’ continues to laugh at him while Big Mac is screaming in pain from his crotch as Apple Bloom is comforting her dear brother.

Apple Bloom glares at her possessed sister, “Applejack! What the hay is wrong with you?! You think hurtin’ my dear brother is funny?! Applejack I know wouldn’t hurt her family just for laugh!” Apple Bloom gives a disappointed look to ‘Applejack’ who doesn’t really care what she said to her.

“Aw! You such a cutie pie!” ‘Applejack’ gives a fake smile to Apple Bloom before grabbing Apple Bloom’s mane.

“Applejack?! What are you doin?!” Apple Bloom yelling at her sister.

“You and your hillbilly brother should go back where they came from! You varmint!” Jack in Applejack’s body use his power to levitate both Apple Bloom & Big Mac and both of them are trying to escape while give them a bigger grin.

“So long, partners!” ‘Applejack’ launching both Apple Bloom and Big Mac to the sky high!

‘Applejack’ laughs, “That will teach them a lesson, those hillbillies!” She burst into a hysterical laughter, “Ha ha ha ha ha ha ha ha ha ha ha ha ha ha! This is like a video game I play but it even more entertainin’!” She laughs and laughs until she notices an apple on the ground.

She pick up an Apple, “Well, my fun time of messin’ with Equestria sure make me feel hungry!” ‘Applejack’ took a bite to an apple and continues to eat the Apple until it’s all gone, “Man! Those hillbillies made one tasty Apple! I need to get their secret recipe so I could have all tasty apples for ma self! He he he he he he he! Man! I really need to stop talking like a hillbilly” ‘Applejack’ went to Sweet Apple Acres in order to find their secret recipe.

At Carousel Bontique, Rarity is blowing on bag to calm herself down while Spike, Elements of Harmony, Ember and rest of the dragons explains the whole story about Jack Possessive.

“So, that demon is the one who cause the big mess in my shop! Even I can’t see him, I will give him a piece of his mind for destroying all of my dresses!” Rarity making an angry face as Spike trying to calm his beloved mare down, “At least, I stop him from cutting all of your mane!” Rarity looks at Spike and give him a bear hug, “Oh, thank you, my Spikey-Wikey! I’m so glad I didn’t have to go through that situation again!” Rarity was referencing one time when she uses a wrong shampoo and it removes all of her mane, It took months for her to have her mane back to its original state.

“You.... Welcome...... Rarity!” Spike is unable to speak properly as Rarity is hugging him tightly while Garble and rest of the dragons laugh at him before Ember hit Garble with her bloodstone scepter.

“Ouch! What did I do?” Garble asked Ember.

Rarity finally let go of Spike as he breath in and out, “I can breath!”

Suddenly, both Apple Bloom and Big Mac flying toward Carousel Bontique and Apple Bloom shouting at them, “Everypony! Look out!!!!!!!” they crash land at the top of Carousel Bontique and because their strength, half of the building get destroyed, much to Rarity’s dismay.

Pinkie Pie look at you, “Here’s where Rarity goes berserk”

“My Carousel Bontique!!!!!!!!!! NOOOOOOOOOOO!!!!!!!!!!!!!!!!!!!” Rarity starting to crying like if she lost her beloved friend and scream at the sky, “CURSE YOU, JACK POSSESSIVE!!!!!!!!!!!!!!!!”

At the kitchen, Jack in Applejack’s body looking all over the place for Apple family’s secret recipe while Granny Smith is sitting on her racking chair, tied up and gagged as she tries to figure out why her granddaughter suddenly becomes a crazy pony and ransacking their kitchen, unaware that her granddaughter is possessed by Jack Possessive.

“Where is their secret recipe?! Those darn hillbillies must be hiding their recipe from me! I will not rest until I find their secret recipe! Muhahahahahahaha!” Jack give out an evil laugh as Granny Smith look confused at her possessed granddaughter’s evil laugh.

Author's Note

Spike got his beloved Rarity back but unfortunately, Applejack is possessed by Jack who is determined to find Apple Family’s Secret Recipe so he can make his own delicious apples and holding Granny Smith hostage.

Will Rarity forgives Apple Bloom and Big Mac for destroying Carousel Bontique?

Those who are wondering where this story take place? In term of continuity, this story take place around Season 7 (Take place between It isn’t the Mane Thing About You and A Health of Information)

Like I say, only Dragons can see and physically grabs Jack’s spirit while ponies and other creatures are unable to see or physically grab him..... That’s why Elements of Harmony didn’t do anything to grab Jack’s spirit.

EDIT: I forgot to mention that Jack Possessive and his father are considered to be arch-enemies of all Dragon creatures since all of dragons absolutely despise them.
