Prince Blueblood, a white coated, blonde maned and tailed unicorn, wearing a white suit with a blue bowtie stared at the night sky from the window in his private estate, in one of the highest class neighborhoods in Canterlot.

He pondered to himself, "Curious, shouldn't she be raising the sun by now?" As he took a sip of wine from a glass he was holding.

"Must be that old age finally catching up to her" He said with a dry chuckle.

"Oh if only, maybe then the throne would finally be within my grasp..." Blueblood mumbled to himself, just as several knocks rang through the door.

"Sir?" A female voice spoke out, one Blueblood was familiar with, a maid.

"What is it?"

"There's some pony here to see you"

"The sun isn't even up yet! ... *Sigh* Tell them to wait by the living room, I'll be down in a moment" Blueblood said with a groan as he walked to a mirror and began quickly grooming himself.

The maid left with a "Yes sir"

Once Blueblood finished his preparations, he walked downstairs to meet whoever was bothering him at this hour.

He reached his living room, spotting a stallion in all black clothing, alongside a black top hat sitting cross legged on one of his chairs.

Or at least, he assumed it was a stallion, as it looked like he didn't have a mane, tail, or even face, as it was covered by a veil of black smoke.

The dark man spotted the prince, saying "About time, you know it's rude to keep guests waiting right?"

"Not if they show up unannounced at the break of dawn. Who are you? And what is your business with me?" Blueblood asked as he crossed his arms.

"Nothing bad, nothing bad, don't worry. I'm just here on behalf of a friend for a proposal" The dark man answered, as he leaned back on his chair.

The prince grabbed a chair with his magic, placing it across the man, and sat down.

"Continue"

The dark man hummed, saying "A friend of mine has just moved into the country, from another nation far away, and he wants to create a company, here in Canterlot"

Blueblood nodded, asking, "Who is this friend? And why didn't he come with his proposition himself?"

"His name is Tony Stark, and he does send his apologies for not asking you himself, but he wanted to be in Ponyville to watch the summer sun celebration, and i decided to do him the favor" The dark man answered as he placed one of his hands on an armrest.

"Hm, well I don't see how I can be of any help, you'll have to ask the princess at her court for a business license, at least that's how we do it here" Blueblood said with a shrug.

The dark man leaned forward, saying "I'm sure you'll be plenty of help" As he reached for something inside his trench coat.

"Are you going to attempt a bribe? A warning before you do, you can't afford it" The prince said as he leaned back on his own chair.

"A bribe? Of course not. Bribery won't be needed once you see what Stark has in mind for his business" The dark man answered as he pulled out multiple blueprints out, and handed them to the unicorn.

Blueblood grabbed the plans, just as the dark man rose from his seat.

"I'll be taking my leave now, have a good day" The dark man said as he made his way to the front door of the home.

"You never said who you were" Blueblood asked, before the man left.

The dark man turned to the unicorn, saying "I'm just somebody who wants an interesting story" As he opened the front door.

The prince watched the man leave, then opened one of the blueprints given to him.

Stepping outside, the dark man placed his hands in the pockets of his coat, as he turned and stared out into the direction Ponyville was located in.

'How far will your story go, Stark?' He thought to himself as he then looked up the sky, seeing the missing mare on the moon.

...

'No use in loitering, on to the next stop' He thought as he began walking down the street.

Stark walked forward, something Nightmare Moon immediately noticed, alongside a strange glowing blue ring on the man's chest, another thing she would figure out about the stallion at a different time.

Twilight tried to stop the man, but it was too late, as he began speaking.

"So you're going to make the night last forever? I don't mean to be rude but that's kind of idiotic" He said.

The alicorn scowled, as Stark continued speaking.

"I mean don't get me wrong, i like the night as much as the next guy, but an eternal night? That'll result in the end of the world" He said, making it sound like obvious knowledge.

Nightmare Moon leaned forward, her scowl now replaces with a small, fake smile, as she addresses the man directly.

"Really now? And, who might you be?" She asked.

"I'm Tony Stark, a pleasure" He answered with a smile that greatly irritated the alicorn.

"Well Stark, let me tell you something about the laughable warning you've attempted to give me" The alicorn said as she placed her hands on the platform railings.

Then proceeding to crush the railings, light up her horn and shoot a magical blast at Starks feet, making him jump back, almost falling on his ass.

"IT'S A LIE!!" Nightmare Moon screamed as the mayor, now seeing that whoever this villain was, is now attacking innocent citizens, decided to step in.

She commanded "Seize her!" At multiple royal guards, who were all pegasi, had blue manes and tails, and wore suits of golden armor.

The three rushed the alicorn, each guard being armed with spears.

"STAND BACK FOOLS!" Nightmare Moon exclaimed as she summoned multiple lightning bolts to get the guards, incapacitating them.

She began cackling once again, turning into the starry purple mist, slithering towards the buildings exit, opening the doors and disappearing into the night sky.

Stark looked at the scorch mark the magical blast had left, then to the injured guards struggling to get up.

'I guess I should've expected there to be villains in this world, I just didn't expect to fight one so soon' He thought to himself as Twilight approached him, giving a very sleepy and panicking spike a piggy back ride.

"Stark! I'm returning to the library, I suggest you go too, it should be safe there" She said as she and the rest of the crowd made her way to the exit.

'I should go, she seems to know more about this Nightmare Moon, that's probably my best bet in actually finding her' Stark thought to himself as he followed the unicorn.

Outside, the rainbow haired pegasus watched as Twilight and Stark hurried to the library.

"Where are they going?"

Waking into the library, Stark was met with the sight of a frantic Twilight throwing books throughout the place, repeating something about some elements.

She continued scouring, asking herself "Ugh! How am I supposed to stop Nightmare Moon without the elements of harmony?"

"The elements of what?" Stark asked as a sudden blue blur sped by him.

It was the rainbow haired mare from before, saying "She said elements of harmony!" At Stark, before addressing the lavender unicorn.

"What exactly are they? And how did you know about Nightmare Moon, huh? Are you some sort of spy?!" She exclaimed, cornering Twilight to the back of the library, but before she could interrogate further, the orange coated mare yanked her tail.

"Settle down sally! Yer freaking out the poor girl, and making us look bad in front of the delegate!" She exclaimed, gesturing towards Stark.

"That is what you are, right?"

"Uh, yeah, something like that, I'm Stark, though you probably heard that back at the stage hall" He answered, adding on "And to clarify, my species name is human"

"I did see that, rather foolish if I'm being honest, darling, but admirable nonetheless, you may call me Rarity" Said the white coated unicorn.

"I'm Rainbow Dash, and admirable is right! You were the only other human to try and stand up to that crazy mare! Respect" The rainbow haired pegasus said as she patted Stark on the shoulder.

The yellow pegasus only said "I'm Fluttershy" With a soft tone.

"And am Applejack, good to meet ya friend" The orange coated mare said as she shook Starks hand.

"It's good to meet you all, now, weren't we going to discuss something about Nightmare Moon Twilight?" Stark asked, as every pony else looked to the unicorn, waiting for an answer.

After sighing, Twilight recounted how she had read about the predictions of Nightmare Moon, how a select group of magical items were the only things that could stop her, being the elements of harmony, only she didn't know what they were, or where to find them.

Stark listened through Twilight's story, before the voice of Pinkie pie spoke from behind him.

"Stark! Catch!"

He turned around, narrowly catching a large book before it hit him in the face.

"Ah! Could you please not throw books at me?" He asked the pink mare, who only giggled out a "Sorry!" In response.

Twilight snatched the book from Starks hands with her magic, exclaiming "Where did you find it?!"

"It was under E!" Pinkie responded, to which Twilight blanked out an "Oh"

"Wait, you didn't look in E?" Stark asked, only receiving a grunt from the mare.

Twilight began reading from the book, which detailed the existence of six elements of harmony: Kindness, Laughter, Generosity, Honesty, and Loyalty, with the sixth being an unknown mystery.

The book also detailed the last-known location of the elements, being the ancient castle of the royal pony sisters, being located in what was commonly known today as the everfree forest.

"The everfree forest?!" Exclaimed all the mares in shock.

'Must be a pretty crazy forest' Stark thought to himself as Twilight approached him once again.

"Stark, it would be best if you stay here, and wait all of this out while I attempt to stop Nightmare Moon" She said, seeming hesitant to follow through.

With a sigh, she continued speaking, saying "If I don't come back, please find some pony to take care of Spike" As she turned around and sprinted out the door.

"Hey! Wait up!" Rainbow Dash exclaimed as she and all the other mares followed Twilight out the library.

Stark stayed behind, waiting till the coast was clear of anyone else before opening up the menu from his watch again, deciding to withhold letting anybody know of his Iron Man alter ego for the time being.

"Alright! Let's see.." Stark said, giddily scrolling through the holographic menu.

"Might as well go for the strongest one I have available" He continued, selecting the armor he wanted.

Instantly, the armor materialized around him, leaving Stark now donning the mark six, a suit that had the usual color coding of red and gold, its most noticeable difference being its upside down triangular arc reactor, as opposed to the usual circular one.

He moved around, flexing his arms, legs, and head as he felt the weight of his armor out.

"Well, no better time to test it out right?" Stark asked himself, as he stepped out of the library, and prepared to take off, something he thought would have needed practice, but it would seem the he was reincarnated with the knowledge of at least knowing how to use the suits thrusters.

"That was certainly nice of the guy" Stark said, referring to the dark man.

"Whom are you referring to sir?" A voice, which Stark recognized as Jarvis, suddenly spoke up, from his helmet display.

"Whoa! Jarvis?! That you?"

"Yes sir, it's me, a good day to you too"

'And he installed Jarvis?! Aw man, I'm going to have a blast' Stark thought to himself as he activated his thrusters and rose up to the sky.

"Great to have you bud, but this is no time for pleasantries, we've got a situation" Stark said as he began flying towards the forest at the towns edge, assuming it was the Everfree forest from Twilight's legend.

"I heard, are you sure engaging Nightmare Moon is a good idea? If the legend is to be believed, only the elements of harmony can defeat her"

"I'm sure we can at least stall her while Twilight finds and preps them"

"If that's the case, then you should go to the castle of the two sisters, that is where Nightmare Moon should be" Jarvis said, just as he scanned the forest, finding the ruins and highlighting them for Stark to see, to which he said "Gotcha" As he flew towards it.

In said ruins, Nightmare Moon materialized from the starry purple mist she had turned into.

'The trials for the fools following me have been set, it should give me enough time to find those dreaded elements and destroy them' The alicorn thought to herself, taking a few steps forward, just as something crashed through the wall, tackling her and exiting through the other end.

Whatever tackled her angled their direction downward, and threw her onto the forest floor.

Using her wings to stop the crash course she was heading in, she got a good look at what had attacked her.

Nightmare Moon scowled at the Iron Man Infront of her, saying "Do NOT touch me again, vile golem"

"Golem? You wound me, I'm not that bad looking!" Stark said as his mask flipped open, revealing his face.

The alicorn looked stumped for a second, asking "Stark? What in Tartarus do you think your doing?!"

"I'm pretty sure you know, I mean I tackled you, isn't that enough of an answer? Im here to stop your eternal night" Stark responded with an eyeroll.

"Stop me?" Nightmare Moon asked with a laugh. She continued, saying "This is the best Celestia could send against me?! Very well, let's see what that shiny armor of yours can do" As she lit her horn.

"I'm sorry, but I don't know anyone called Celestia, much less work for her" Stark said as his mask reclosed over his face.

"You expect me to believe that? Ha!" Nightmare Moon exclaimed as she shot a magical blast at the Iron Man, which he dodged, retaliating by raising his arm and shooting a repulsor blast from his palm.

The alicorn conjured a magical shield to block the blast, saying "Magical attacks? You keep on surprising me Stark, but alas, whatever other tricks that suit of yours has won't be able to stop me"

"Guess we'll see, right?" Stark said as he entered a defensive stance, aiming both of his palms at the alicorn.

Nightmare Moon grinned, this would be quick.

She charged forward, dodging the incoming repulsor blasts being shot by Iron Man, as she conjured a magical spear.

She reached Stark, thrusting the spear forward, intending on finishing the man right then and there, but failed as Stark narrowly blocked the attack with his arm, resulting in several sparks flying off the armor, as he then activated his foot thrusters, kneeing the alicorn on the stomach, and blasting her chest with a repulsor blast, sending her stumbling back.

Stark then revealed a small missile from an arm compartment, shooting it at the ground near where Nightmare Moon stood.

The missile impacted, resulting in a bright hot fireball, forcing the alicorn to cover her eyes for just enough time to let Stark charge forward, tackling the mare once again, dragging her through the dirt, until she impacted a large boulder.

Stark sent a punch intended for the alicorns head, but only impacted rock, as she had used a teleportation spell to appear behind him, shooting his back with a magical blast, then magically grabbing hold of the man, lifting him up and slamming him onto the boulder, then threw him at a nearby tree.

Once his back impacted it, she flew forward, covering her now balled up fist with her magical aura, and punched the man's chest, sending him through the tree, leaving a noticable dent in the armor.

Stark fell on his back, flipping backwards and landing in a kneeled position, firing another repulsor blast at the alicorn, which she dodged, as he activated his thrusters and charged forward, shooting another missile, this time directly at the mare.

Nightmare Moon conjured another shield, but didn't have enough time to reinforce it, resulting in it shattering upon the impact of the missile, making her stagger back, just as Iron Man emerged from the fire and punching the alicorn straight on the head, knocking her helmet off.

Stark landed on the ground, turning around to punch the mare again, but failed because she caught his arm, then proceeded to squeeze it, her superior alicorn strength allowing her to easily dent the armor.

Stark raised his other hand to shoot Nightmare Moon with a repulsor blast, but failed once again as she grabbed hold of his hand with her magic, and used her own free hand to grab the man's throat, bringing him up to eye level.

She could feel a bleeding cut on her cheek, saying "I must say I'm very surprised Stark, you engaged in a fight with me and didn't immediately perish? Commendable, if you weren't my enemy I would have you as part of my personal guard" As she grabbed her helmet with her magic and put it back on.

Stark answered by saying "Appreciate it" as he shot a repulsor blast from the arm currently being squeezed at the alicorns face, and activating his foot thrusters, flying away from from her grasp onto the air.

Nightmare Moon shook her head, seeing the now hovering Iron Man, exclaiming "And you can fly?! Just who forges this armor?"

"I don't even know why you asked, I'm not gonna tell you even if I knew" Stark said as he shot another repulsor blast, which the mare dodged.

He continued speaking, saying "Anyway, we should wrap this up, would like to have breakfast on a sunny day you know"

Nightmare Moon would have liked to continue fighting, as Stark has been one of the better opponents she's faced, even lasting longer than Celestia. But it was for naught, as she needed to return to the ruins and destroy the elements, who knew of that lavender unicorn and her friends passed through the trials.

If she were to attempt defeating Stark in a regular battle, it would take far too long, even if it would end with her victory.

Deciding on what to do, the alicorn dodged another repulsor blast, responding by summoning a lightning bolt, having it collide Starks chest, sending him to the ground.

She kept the bolt of electricity centered on Stark for a solid five seconds, stopping once she saw the armor smoking and singed.

Not waiting by to see Starks scorched body inside of his armor, Nightmare Moon turned into starry purple mist, quickly returning to the ruins.

Stark however, knew that electricity didn't really do anything against the mark six, and every other suit following it.

'In fact..' Stark thought to himself as he began speaking, asking "Jarvis, how are we doing with power?"

"We are at four hundred percent capacity"

Stark smiled, saying "Thought so" as he flew into the sky, in chase of the alicorn.

Nightmare Moon reached the ruins, thankfully, just in time, as Twilight Sparkle was in the process of trying to activate the spark that was supposed to activate the dormant elements, which were stone balls with multiple different shapes being etched on each one.

She entered the ruins, still in her astral form, surrounded the elements, and engulfed them in a small twister, intending on taking them with her to a different part of the castle with a teleportation spell.

Twilight, figuring out what was going on, exclaimed "The elements!" As she jumped into the twister, hoping she would also be transported.

It worked, and the two appeared in what was once the throne room, with Nightmare Moon having the elements in her possession, cackling as victory was within her grasp.

Twilight thought of a way to reach the elements, but before she could, something crashed through the ceiling, landing Infront of her.

Iron Man turned towards her, saying "Purple lady whom I do not know, I'm going to distract her, and you'll get those elements up and running, alright?" Receiving a slightly confused, but determined nod.

"YOU AGAIN?!" Nightmare Moon exclaimed as she lit her horn, preparing to fire a blast at the man, but couldn't as Stark fired three stronger repulsor blasts from his palms, and arc reactor first.

The beam hit the alicorn, sending her back to a wall.

Stark charged forward, winding up a balled up fist, failing to hit true as Nightmare Moon exclaimed "ENOUGH!" As she impulsed herself from the wall by using her hoofs, dodging the attack and slashed the man's chest with her magically protected hand, leaving multiple surface level gashes on Iron Mans armor.

"Sir, the arc reactor is damaged, and the suit has sustained minor damage, I'll have to divert extra power to suit functionality" Jarvis said, just as Stark turned and dodged another magically conjured spear.

He was however, too slow to dodge the following kick to his stomach, and magical blast to the chest right after, which sent him tumbling through a wall.

The alicorn didn't bother pursuing Stark, hoping that he wouldn't come back as quickly.

'Now, it's time to finish this, no more delay' Nightmare Moon thought to herself as she used a teleportation spell to appear Infront of Twilight.

Stark was in another room of the castle ruins, slowly getting to his feet.

"That is one strong woman" He said to himself as he fully stood up, asking "Jarvis? How we doing with the suit?"

"We've suffered heavy damage, but there's still enough power to last you through another encounter with Nightmare Moon, should you face her again"

"Here's to hoping I don't, who would've thought this magical pony land had such a tough enemy?" Stark said as he destroyed a wall with two repulsor blasts, revealing an exit to the everfree.

"I'm sure Twilight has activated the elements by now"

Stark stepped outside, activating his thrusters and taking to the air, but before he returned to the town, he decided to check if Twilight had infact successfully activated the elements, since he was hearing commotion nearby.

He hovered over to one of the many windows of the ruined throne room, just as the sun suddenly shot out into the sky.

Even though that confirmed victory, Stark still decided on taking a closer look, seeing Twilight, now wearing a tiara, alongside her friends, who were now wearing fancy looking necklaces.

"Elements I'm assuming?" He asked, receiving a "Affirmative" From the AI.

The mares were all bowing to a larger mare, around the height of Nightmare Moon, and had wings and a horn, but had a snow white coat, and her wavy mane and tail were a mix of the colors cyan, green, blue and pink, who wore a white dress, much like rarity.

"Who's that?"

"Princess Celestia sir"

"Ah, the one and only"

Near the group, laid two other alicorns, shorter than Celestia, but slightly taller than the rest.

One of them had a dark blue coat, alongside a blue mane and tail, and wore a blue dress.

The other, had a black coat, alongside a dark purple mane and tail, and wore a tattered purple dress.

"And who are those two?"

After scanning, Jarvis answered, saying "The one on the left seems to be Princess Luna, while the one on the right, is Nightmare Moon"

"Really? Huh, she's smaller now"

The group noticed the two newcomers, with Celestia instantly lighting up her horn and approaching the now smaller Nightmare Moon.

The black alicorn backed away in fear, a scowl plastered on her face, as Celestia shot a beam at the mares chest.

The beam began to not only drill a hole on the alicorns chest, but was also draining what was left of magic in her body, causing her to scream in agony.

"The hell is she doing?" Stark asked.

"It would seem that Celestia is finishing Nightmare Moon off"

"What?!"

Even though he knew Nightmare Moon was a villain, something didn't seem right the whole situation, her new appearance, and the fact that this angelic looking princess was about to kill her. There had to be more to this!

...

"What is your next move sir?"

...

"Activate smoke bombs, target areas near where Celestia is standing" Stark said, as multiple missile compartments from his shoulders opened, releasing the firepower.

Luna approached her sister, seemingly wanting to say something, but couldn't as the bombs broke through the window, impacting the ground and quickly covering the throne room in a thick veil of smoke.

Stark entered, finding Nightmare Moon using his helmet display, and grabbed her, taking off once again.
