Avengers find Equestria

Twilight has never felt so good.

There she was with all her friends (Well, two thirds of all her friends), ready to travel to Canterlot to receive a homage for defeating Discord. After all they went through yesterday, they more than deserved a break. But the important thing is that they were together, back to normal, and their friendship was stronger than ever.

"Hey, Twilight" Spike the Dragon said

"Yes, Spike?" Twilight replied

"When are we gonna remove Discord from our backyard?" Spike points outside the window at the petrified villain half-covered in moss and bird poop.

"Oh. Well, I'm sure that Princess Celestia will be sending somepony to take it back to the Canterlot Gardens when our chariots arrive"

"Speaking of which" Rarity chimes in "Where are the girls? I, I mean, we don't want to be late"

"I'm sure Rainbow Dash and Pinkie will be arriving very soon…"

As if on cue, the door of the library suddenly bursts open which sends Fluttershy hiding behind a table "NOW we're in 'Twilight's Zone'!" Pinkie shouts as Tony Stark in Rainbow Dash's body (Rainbow Stark) falls in the floor.

"Oh, fuck me" he says as the surprised ponies approach them.

"Pinkie, what is wrong with—?"

"Twilight!" Pinkie shouts "You gotta help! Rainbow Dash doesn't remember me! She doesn't remember how to fly! She fell from the clouds, and hit her head! Now she thinks her name is Pony Spark! I tried to say it isn't, but she won't listen!"

"Calm down, Pinkie, calm down" Twilight says "Rainbow Dash, are you alright?"

Stark looks at the purple unicorn, studying her face for a few seconds before answering

"I'm swell" Stark said with a smirk "What about you, Juniper Lee?"

"Juniper Lee?" Twilight asks confused

"See?" Pinkie says

"Rainbow Dash, you don't remember me?" Twilight asks "It's me, Twilight Sparkle"

"Twilight Sparkle? Really?" Stark asks with a chuckle "Is that because your body glows in the sun like Robert Pattinson's?"

"What?"

"Look, you are all very cute, but I really need to wake up and go home now" Stark says "So, if I may…"

"You ain't going anywhere" Pinkie blocked the door "Twi! Do something!"

"Rainbow Dash!" Applejack shouted "I'm sure you think this is all very funny, but we don't have time for your jokes! The Princess' chariots will be here any minute to pick us up, so we need to be ready and that goes for you too!"

"Cute, you remind me of Pepper" Rainbow Stark said "You even have her freckles! I'm gonna call you Pepper Jr."

"Rainbow Dash is acting really weird" Fluttershy tells Twilight "Do you think she's still under the spell of Discord?"

"I'm not sure…" Twilight says "She's not acting like she did when she was, besides, she's not getting grayer"

"Well, I don't know about grayer, but I definitely got a little gayer" Rainbow Stark says "Will you hallucinations let me go now?"

Twilight frowns "Whatever it is, she's not being herself… Don't worry, girls. I will bring her back" Twilight's horn lights up.

"Whoa! …the hell?" Stark says, surprised, as Twilight touch his chest with her horn.

After a little twinkle, Twilight lifts her head, smiling "Now, you remember"

Stark looks both ways "Ooookaaaay…. I remember what?"

Twilight looks confused "I… but… Let me try again" Twilight touches Stark with her horn again, and then stares at him, waiting for a reaction.

"Are you done?" Stark asks, bored

"I don't understand!" Twilight says "This usually works!"

"Hmm. Déjà vu" Stark says "Look, I would love to quip about your performance issues, but I already did that to another guy and I don't like to recycle material"

Twilight looks frustrated until she gets an idea. Using her magic, she teleports all her reports over Stark's head "Hey, how did you…?"

"Read this!" Twilight tells him "When I forgot about how wonderful my friends were, Princess Celestia sent me these to remind me. It will do the same to you"

Stark shots her an annoyed look. Is this how his subconscious looks like? He's disappointed. Finally, he shrugs and read the letters.

"So" Twilight asks when he finishes reading the last one "Got anything?"

"Yeah, diabetes" Stark says "Look, I don't know who you are, but…"

"ARGH!" Twilight screams frustrated "I'm Twilight Sparkle! I live here in the library, because I'm very studious! That's Pinkie Pie, she's upbeat and parties a lot! Applejack works at the Sweet Apple Acres! Rarity makes dresses! Fluttershy takes care of the animals! And YOU are Rainbow Dash! Likes to fly, likes to compete, likes to win! WE'RE BEST FRIENDS!" Twilight puffs "You… Do you remember any of that?"

Rainbow Stark stares at her for a few seconds, before rubbing his temple "Oh, fuck… there's no way I'm making this up… This is real… Unreal… Look, I… I don't know how to say this, but… No. I don't remember any of that. Because there's nothing to remember. I'm not who you think I am. I'm not Rainbow Stash"

"Rainbow Dash!" Applejack yells

"Yeah, that" Stark replies

"I told ya already. This is no time for ya pranks!"

"I'm serious!" says Stark "I have no idea what happened or what's going on, but yesterday I was a man who went to bed on his penthouse, today I woke up as blue, winged horse on a cloud. There are so many things wrong with that last part that my brain is still processing it. I'm not your friend. I may look like her, but I'm not her. As a matter of fact, I'm not even a her, I'm a him"

"So, your name really is Pony Spark?" Pinkie asked

"No, my name is not Pony Spark"

"But you said your name was Pony Spark" Pinkie replies, suspicious

"No, I didn't, Tinkie Tie"

"Is this possible?" Rarity asks Twilight

"I don't know" Twilight answers lifting some random book off the shelves "There may be something about body exchanges somewhere around here, but I don't know. I've never heard about anything like this outside of Pony Tales."

"Couldn't you use the Elements to bring her back?" Spike asks

"Hey, what are you supposed to be?" Rainbow Stark asks Spike, noticing him for the very first time

"I'm a dragon"

"A dragon?" Stark asks "So… shouldn't you be, like, trying to eat them or something?"

"What?! No!" Spike says, shocked "I don't eat ponies, I eat gems"

"I'm very tempted to go back to my 'I'm high' theory right now" Stark says, more to himself than anything else.

"We can't use the Elements, Spike" Twilight answers him "We need everypony for them to work, and Rainbow Dash's not here, so her element won't…! HER ELEMENT!"

All the ponies and Stark turn their heads to Twilight. "Her Element! Of course, how could I be so stupid? That red burst of light of yesterday... That is the cause of this!"

Stark now remembers yesterday's Unibeam and how it seemed to collide with a 'red burst of light'. Things are starting to make sense… kind of…

"The Elements can do that?" Fluttershy asks

"I don't know" Twilight answers, quite frustrated. She hated not knowing things, and today was surpassing her quota of 'un-knowledge', and it wasn't even noon! "Let's be honest, nopony really knows exactly what the Elements can or can't do… except, maybe… Spike! Take note"

Spike diligently grabbed his pen and paper, ready to transcribe Twilight's letter.

"Oh, so you're like her secretary, or something?" Stark asks Spike

"Spike does everything I ask him" Twilight answers "He writes my letters, he cleans the library, he organizes the books, and he makes sure that everything that was needed to be done was done" Spike gives a look of proud satisfaction

"Oh, so he's your Jarvis" Stark says, turning to Spike who doesn't look so proud anymore "I'm gonna call you Jarvis Jr."

"What's with ya callin' everypony 'Junior'?" Applejack asks

"That's right! I forgot about you, Pepper Jr.! Now I just need a Rhodey Jr. and a Happy Jr. and the whole gang will be here"

"Oh, oh" Pinkie says, waving her hoof around "I wanna be Happy Jr.!"

"Sorry, but you're too happy to be Happy" Stark answers

"Aw…" Pinkie moans

"And by the way" Stark says to Applejack "I'm not calling every pony 'Jr.', you're the only pony I have called that. He's a dragon"

"Yeah, but… we use 'pony' for everypony 'round here" Applejack explains

"Really? Don't you think that's a little racist?"

"What's 'racist'?"

"As I was saying" Twilight interrupts, irritated "Spike, take note: 'Dear Princess Celestia, I'm sorry to inform you that the celebration you generously arranged on our behalf will need to be postponed. Rainbow Dash is not being herself, and we suspect it may have something to do with her Element. Do you know anything about the Elements that could allow a pony to become somepony or something else? If not, do you know if anything else could do it? We will try to solve everything regardless of your reply. Your faithful student, Twilight Sparkle.' That's it, Spike. You can send it" Spike nods, rolls the letter, and burns it with his breath.

"You wrote all that just to burn it? Why? She didn't pay you this month?"

"This is how we deliver letters to Princess Celestia. She must be reading it right now" Twilight explains

Stark blinks. He opens his mouth and then closes it. He opens it again, and then closes again. Finally he says "So… We're just gonna wait now?"

"Uh… yes"

"Sorry, no offense, I'm sure Princess Bubblegum is a very wise monarch, but I don't take backseats. I'm a proactive kind of guy" Stark says

"But we can't do anything!" Twilight said "We don't know anything about the Elements"

"I know everything about elements" Stark said smugly "I created one in my garage. I'm a genius, did I forgot to mention that?"

"Oh, really?" Twilight says, unimpressed "So, I guess the genius here would know what the six Elements of Harmony are, right?"

Rainbow Stark's face loses its smugness "Uh… yeah, of course… the six… Elements of Harmony? Yeah, uh… Air, Fire, Water, Earth, Heart and... the Element of Surprise?"

"No" now it was Twilight's turn to look smug "Honesty, Loyalty, Kindness, Generosity…"

"…Abstinence and Civic Duty. Got it"

"…Laughter and Magic!" Twilight concludes, irritated "Now, I hope the 'genius' won't mind, but I'll wait the reply of somepony who actually knows what she's talking about"

"'Laughter and Magic'? We had a guy who did magic and liked to laugh back in my world, harmony wasn't his thing"

Before Twilight could answer, Spike burps Princess Celestia's reply.

"Yuck!" Rainbow Stark says, disgusted "You're gonna touch that?"

Twilight just shoots him an annoyed look before reading "'To my dedicated student Twilight Sparkle, I'm sorry to hear about your problems, but I'm afraid I don't know about any spells that would allow such a thing. If the Elements of Harmony really caused one of your friends to turn into somepony else, it's unprecedented and there's little I can help with. However, I deeply believe that my favorite pupil will find a solution like you always did. Princess Celestia'"

"In short: 'Fuck you, you're on your own'" Stark quips "Look, I know I don't know much about the 'Elements of Harmony', but trust me, I'm a fast learner. I can help you and I want to solve this as much as you do. Do you have any kind of space that could serve as a workshop, you know, someplace with computers, microscopes, or anything that was made after the 17th century?"

"Twi has some fancy looking machines on the basement" Pinkie says

"Great! But I will still need some materials… Excuse me" Stark says, grabbing a piece of paper and a pen. He starts to write but stops, looking at his hoof "I'm holding a pen… with a hoof… no fingers… You know what? I'm not gonna question it" He goes back to his list, checking twice to see if he didn't miss anything.

"I need to use your fax" Stark said, moving towards Spike

"My what?" Twilight asked

"How do you input the address on this thing?" Stark asks while pressing Spike's face

"Hey! Quit it!" Spike says, annoyed

"Your fax is broken" Stark tells Twilight

"MY NAME IS NOT FAX!" Spike yells

"Shut up, Jarvis Jr." Stark says "Do you have any post office on this town? You know, mail? That doesn't involve magic fire?"

"You want a tour?" Pinkie asks, excited "I wanna do it! I wanna do it! Let me do it"

"Great idea, Pinkie" Twilight says, looking for any excuse to get rid of whoever was inside Rainbow Dash for just a few minutes "You may escort… uh…"

"Stark. Tony Stark"

"…Stark through Ponyville. Show her, sorry, him everything, and help him with his list, mail, and… well, whatever"

"That will be so much fun!" Pinkie hops with glee "Follow me, Pony Stark"

"After you, Tinkie Pie"

"What a rude little…" Applejack says, after the two ponies left the library "Ya know, he kind of reminds me of a snob cousin of mine from the Orange side of the family who lives in Manehattan. His name was Mandarin, I think. I betcha he and Stark would get along really well"

"I'm sorry, girls" Twilight says "It seems we won't be going to Canterlot any time soon"

"We understand, dear" Rarity says "Let's hope we'll find a way to bring Dash back"

The ponies give their goodbyes to Twilight and go back to their homes. Twilight and Spike search through all the books of the library for something, anything that could help them understand what exactly is going on and what they should do. The research proves fruitless as Spike grows tired and Twilight frustrated. They barely noticed that three hours had passed and that Pinkie and Stark were just arriving back to the library.

"…but that was before the pickle sandwich exploded" Pinkie tells Stark "And that was how Equestria was made"

"You lost me after flying competition in Cloudsdale" Stark replies

"Oh, hi Twi" Pinkie says, looking at the piles of books covering the floor "Redecorating?"

"Let me guess" Stark says "You didn't found anything"

"No" Twilight confesses "What about you?"

"Well, after Cotton Candy Hair here took me all over the place, I managed to find a hardware store. They didn't have everything, this being middleagesville…"

"Ponyville" Pinkie corrected

"…well, as I was saying…" Stark tries to continue, but a grey, winged pony flies past him, colliding against the library wall, holding a big box.

"You got mail!" Derpy says

"Well, that was fast. Color me impressed" Stark says

Twilight takes the box from Derpy who flies away "Wow, that's heavy!"

"Yeah, that's for me" Rainbow Stark says, grabbing the box

"Excuse me" Twilight says, holding the other side of the box "But this is addressed to me, see? 'To: T.S.'"

"Yes, 'To Tony Stark'" Stark says, pulling the box to him

"No. To Twilight Sparkle!" Twilight says, pulling the box back to her

"Tony Stark!" Stark pulls the box

"Twilight Sparkle!" Twilight pulls back

"Tony Stark!"

"Twilight Sparkle!"

"TONY STARK!"

"TWILIGHT SPARKLE!"

"Tony Starkle! Twilight Spark! Tara Strong!" Pinkie cheerfully chimed in

"Look, Stark" Twilight said, irritated "It doesn't matter how you're called back where you're from. Here, you're not 'TS'. Here, you're 'RD'"

"Yeah, RD Junior" Spike says with a smirk

Rainbow Stark shoots a 'Really?' look to Spike before turning to Twilight "Look, Sparkle. It doesn't matter how I'm called anywhere. This is for me. I ordered it to be delivered here from the hardware store. It's my tools, see?" Stark opens the box, showing an assortment of lab tools.

"Oh… uh, sorry" Twilight says, embarrassed.

"It's okay" Stark says "You're paying for it, after all"

"WHAT?!"

"I told them to put in your tab. I don't have any money here, and I deduced you'd have plenty since you're close friends with the royalty" Stark explains, carrying his box towards the basement "Besides, I will pay you back if you ever visit my dimension. I'm rich, fid I forgot to mention that?"

Twilight just looks incredulously at the audacity, as Rainbow Stark carries the box down the basement.

"Also, I would like if you, Mushu, and the rest of the Care Bears would meet me down here in two hours if possible" Stark shouts down from the basement.

Twilight sighs. This will be a long day.
