OST

Luna was sent falling into a wall, leaving an imprint of herself, while Celestia and Discord were fighting with all they had against the man. They would've used their magic, but they would need time, time that the man wasn't willing to give. A hard kick to the gut and Celestia joined Luna in her wall breaking game.

"Ow." That was all either could say, as they never had faced a foe this powerful. "This doesn't make any sense, how is he so strong that he fight off all three of us an still keep fighting?" Luna asked nopony in particular.

Celestia had just freed herself and was now freeing her sister. "I'm not sure Luna, but he knows us and says he was around a thousand years ago, if what we heard so far is any clue." She pulled Luna to the floor, helping her to her hooves.

"But it still doesn't add up. If what he says is true, then he would be immortal like us! And I'm sure we would remember such an odd creature!" Luna was starting to lose her mind from trying to figure out the mystery.

"Well, we'll think about it later, right now Discord looks like he could use some help about now." Sure enough, Discord, the god of chaos, was being pushed back, completely on the defensive. The man, unrelenting in his attack, used everything on his person, from his sword, to his fists, to his boots, and even to his own head, rage and bloodlust burning behind his crimson red eyes.

Discord caught a lucky break when his assailant missed on a downward swing, allowing him to retreat back to the sisters. "Jump in anytime, girls! No rush!" He panted out, his voice dripping with sarcasm.

As Celestia and Luna got ready for another fight, the man relaxed his stance. "I see my present power isn't enough, very well. Witness the end result of what he did to me." He stabbed his sword into the ground, resting his hands on the top of the hilt.

"Brillo, sombra de luna." (If you want the translation, copy and paste to google translate on Spanish to english.)

A bright flash of black light blinded everypony, but when it faded, what stood in the mans place was a suit of jet black armor with two dim, but noticeable red eyes in the helmet, with a blood red sword.

"This is the first form I took to when Discord threw me into that pit of misery. I became widely know by the inhabitants as 'The Black Knight'." It spoke with the man's voice, albeit muffled from the helmet. With speeds unheard of, he was already on Discord again, who just barely blocked the swing to his skull.

Before he could continue, however, Celestia was upon him, using every ounce of strength she could draw out to hopefully beat him into submission. But the knight blocked all her attacks with ease. "You have grown stronger from since we last dueled. However." He stuck back with a palm strike to her chest, sending her back a few yards. "That power is useless if you can't hit your target."

On the outside, he was calm and steady, but under his helmet, he blushing up a storm. "Damn, I accidentally cupped a feel. I REALLY hope she didn't notice. But they were really so- NO, BAD BRAIN, BAD BRAIN!!!"

He sensed a hostile presence from behind and swung his sword in a sweep as he turned, only to block an attack from Luna. "You have gotten faster as well, I almost didn't feel you coming. But again." He completed his swing, sending Luna into the wall she just made friends with. "Even if your fast, you need power behind your strikes. What's the point in getting in close if you can't really hurt your target?"

He turned back to Discord, eager to end this fight. "I grow tired of your games, it's about time you died, demon!!" He charged and in a blur, he was on the chaos god again, trying to sever him in half. While he was hammering at Discord, Celestia and Luna were having a mental conversation.

"Luna, how long can you keep him busy?"

"Not long, about five seconds. Why?"

"Because I'll only need three. Just hold him and I'll handle the rest."

"Okay, be careful sister."

"You too, little sister."

With the plan set, Luna darted across the battlefield, slamming her blades against the knights and began to attack at such insane speeds, there was a faint whistle that came as the swords were swung. However, her opponent still blocked her onslaught like she was in slow motion. "This again? You've become a slow learner, Prin-" His eyes widened when he realised her motive. While he was distracted, Celestia moved in from behind and used all of her alicorn strength for a downward slash. It hit it's mark, tearing the man's body in two from the right side of his neck, to his left hip. It seemed they had finally won, if only it didn't end with a loss of life.

That is, until the body vanished into thin air, leaving both sisters' mouths agape, their eyes bulging out.

"I see, so you used each others strengths to make up for your own weaknesses. There being two of you just makes the tactic all the more deadly." The princesses turned to see the man in armor standing two feet from either of them, arms crossed, nodding as like a master would when his student did something well. "Had it been anypony else, that would have worked. But the world I was trapped in was filled with cutthroats and muggers that used the same moves, so I was prepared with an afterimage."

Celestia was awestruck. This creature had the strength to go hoof-to-hoof with not only her, but Luna and Discord as well, all at once no less. And he still hasn't used any magic, or at least, non they could see anyway. Luna on the other hand was pissed, not only had he been able to knock them around like rag-dolls, now he was treating them like they were foals!!

Discord, however was still scared pissless. "How?! How could I have forgotten about HIM?!?! I don't know what happened in the world I sent him to, but it's made him all the more stronger than he was before I sent him.!!" He ceased his mental rambling when he saw a shadow coming closer. He managed to bring up his sword just in time, because had he been an instant slower, the tip of the mans blade would've been poking out the back of his head.

The force of the thrust sent Discord back quite aways, but he didn't continue the attack. Celestia and Luna teleported to Discord, getting ready for round three. So when their enemy lower his sword into a relaxed stance, it came as quite a surprise.

"It's about time I show you what a real fight is all about." He took in a deep breath before letting it out slowly. He stared for a short time, then he got serious.

"Bankai."

A black sphere enveloped the armored man, hiding him from sight completely. The black mass writhed as if in agony. Suddenly, it stopped moving at all. Dead silence lingered in the air for a few moments. Then the top of the sphere broke apart and slowly disintegrated downward till it was no more. What was once an armored man, now stood a black robed man. In his hand, the sword changed again. it was about an arm and a half's length and it's shape looked like a thin sharks fin, but the barbs on it's back looked like a wolf's fangs. It was curved slightly, but it was enough to show it's purpose.

The greatest change, however, wasn't the weapon or what the man was wearing, it was the man himself. Before, he had short black hair and red eyes, now, he still had red eyes, but the whites had turned pitch black and his hair had lengthen past his shoulders, overlapping his eyes. When he opened his mouth to speak, his canines had turned into fangs.

"This is what I became when the undead spirits attacked me. I didn't choose to become this, it was either kill or be killed." He raised his sword till it was mid-level with his abs. "I still have a few tricks up my sleeve, here's my favorite."

He disappeared in a blur of movement, before appearing above Discord.

"HITEN MITSURUGI RYU!!! RYU TSUI SEN!!!"

He swung straight down, splitting Discord in two. Due to his chaos powers, however, he simply turned into two Discords. He had split himself in the instant before the blade connected. "You're starting to really piss me off."

"And you weren't pissed before?!" Left Discord asked, horrified that he only caused him to get mad.

The man answered by dashing to the right Discord and slashing at light speed, turning the clone to dust. Without missing a beat, he charged at the remaining Discord and continued the battle.

While they fought, Celestia came up with a new plan. "Luna, I have an idea, but I don't know if it'll work."

Hearing her sister in her mind again, Luna responded. "If it can give us an edge, then go for it."

"All right, I'm going to channel my magic into you, turning it into strength. If you use your speed with your new might, we might have a chance."

"We've never done anything like that with either of us. Do you think I can handle that much magic."

"Your my sister and the princess of the moon, of course you can handle it."

Reassured by Celestia, Luna gave her the all clear. Soon enough, she began to feel her sister's magic flow into her, giving her unbelievable power. When it was finished, she disappeared like the man did not long ago. She reappeared over the battle and saw the one thing she never thought she'd see outside the Elements of Harmony being used.

Discord was losing. Badly.

His body was cover in wounds one just under his left eye, he was breathing hard, and he could barely hold his sword. It was a miracle he lasted as long as he did.

Luna wasted no more time, as she put herself between Discord and the man. As he swung to sweep her away, she counter-swung and stopped his sword cold. His eyes widened at this, realizing her strength was far greater than before. Using the pause in his attack, Luna push him back by swinging her blades out. This sent the man soaring through the air and into the respective wall.

Or it would have if he didn't right himself in the air and planted his feet in the wall instead, causing cracks to spiderweb out two yards.

He used momentum caused by the landing to shoot himself back at Luna, catching her off guard. He grabbed her throat as he passed, taking her with him as he flew. He stopped by slamming Luna into the oncoming wall, knocking the breath out of her. Before she could retaliate, he pulled her out of the wall and in close to his face, his eyes sending shivers down her spine. "That was a good idea, but you need time for your body to get used to the new power, or it locks up like it's about to right about......now."

Luna suddenly felt like her whole body just shut down and locked up on her, she couldn't move an inch. Placing her gently on the floor, the man turned back to Discord. "You're pathetic. You don't want to atone for your wrongs and hide behind the princesses for protection. And to think, you were the one that sent me to that Tartarus pit."

Before Discord could make a comeback, a light shined off at the end of the room. Turning, they saw the six mares from before were floating, five of them wearing necklaces and the lavender unicorn wearing a tiara. From their sides shot out two rainbows that spiraled upward and then shot downwards towards the man.

Celestia smirked, confident that they have already won now that the Elements were used, but that same smirk changed to a frightened frown when she looked at Discord, who was pale with fear.

As the beam came close, the man made no effort to move out of the way. Instead, he just raised his arm to intercept it and waited.

When it hit, it split back into two separate beams, leaving him untouched. The attack ended, leaving the mares that used it exhausted. When Twilight raised her head, her face held a shocked look. "H-how....it....it's not possible.....the elements never failed us before!!!"

The man just lowered his arm back down and replied in a matter-of-fact tone. "Because I'm still seen by the Elements of Harmony as one of the Bearers."

That brought everypony's thought process to a screeching halt. Luna woke up just in time to see the Elements fail, but she was just as dumbstruck. Celestia was the first to break the silence.

"B-but that's not possible. If what you say is true, then that would mean-" Before she could finish, however, the doors to the room were blown open, send smoke and dust everywhere. Everypony could hear hoofsteps coming from the cloud of dust, which when cleared, revealed black pony like creatures with holes in their hooves and hands, insect wings and jagged horns. The one in front stood out the most however, with it's small crown and large horn.

"Ah, are we interrupting anything?" She asked with a sinister grin.

Celestia bared her teeth in rage. "CHRYSALIS!!! What are you doing here?!?!"

Chrysalis' grin just widened. "Why, just to greet our new friend here. You've been so rude to him that I thought I could give him a helping hand."

The man, however, looked at the newcomers with confusion. "Changelings? So they've become bolder since I've been gone."

The queen looked at him with a seductive smile and half lidded eyes. "Oh? You know of our kind? I'm honored."

The man frowned at this, not affected in the slightest. "Cease your seduction, Chrysalis. Your magic won't work on me."

Now it was Chrysalis' turn to be confused. This creature had spoken to her with such a familiar tone, but something did in fact seem familiar about him. "Who are you? Why do I feel like we've meet somewhere?"

OST

The man smiled warmly at the changeling queen, which caught everypony off guard. "Because, we meet when you were just a filly. Look at how you've grown."

At the still confused look of the queen, he raised his arm towards Applejack. Her Element of Harmony began to glow, then was pulled off her neck by the same glow. It floated to the waiting man's hand, after which he placed it on his own neck.

What happened next was nothing short of breath-taking.

His entire body glow white hot, before dimming to reveal the man had disappeared. In his place stood a pitch black stallion with a lighter black mane and tail with a few blood red streaks running through them. He was wearing armor that looked like the Royal Guard armor, but with a hint of Night Guard to it. His sword was gone, but now he had razor sharp claws. His body was ripped! Where there wasn't armor, veins and muscle could be seen. His height was something else all together. Standing, at least, 7 and a half feet, he stood taller than even Celestia, matching Discords height perfectly.

His eyes were the same, as were his fangs. Still having that warm smile, he spoke with a tone that made him sound much older than he looked. "I've been away for far too long, my little Chrissy."

Chrysalis' eye widened at the sight and even more at the voice, but it was when he called her 'Chrissy' that they started to water. "It...it can't be....Uncle....Night Shadow? Is it really you?"

Night Shadow's smile widened into a grin, showing off his fangs more. "You know anypony else as devilishly handsome as this?" He said while rubbing his chin like he was looking at a mirror.

The changeling queen slowly walked towards the strange stallion, tears threating to fall. When she came up to him, she looked into his eyes, as if trying to see a lie. Her hands caressed his face, while his eyes closed as he leaned into them. Then her arms wrapped themselves around his large barrel chest, while she bawled into said chest. Slowly,as if handling fragile glass, he returned the embrace, soothing the crying changeling, his warm smile never leaving his muzzle. "Shhhhh, everything's alright now. I'm here and I'll never abandon you again. You must have been so scared."

Everypony else was dumbstruck, seeing a ruthless queen breaking down like a filly after a nightmare. Celestia and Luna both stared in wonder, then the full weight of what was going on hit them like a mountain. Their eyes began to tear up. Celestia was the first to rise, then Luna after her body had feeling again. They both approached the hugging pair, catching their attention. Luna was the first to speak.

"It really is you, isn't it? You're alive. We all thought you were dead." Celestia and Luna then bowed to a knee, shocking everypony. What Celestia said next shocked them even more. "Welcome home, Master Shadow."

Author's Note

How that for a twist. And no, I'm not trying to make a gary stu. This is just a new way to show a little missing history in Equestria.
