Celestia's sun shined brightly over the horizon, the streets of Ponyville were littered with friendly faces from different ponies as they went about their day, minding their own business. Some were shopping, colts and fillies were in school, others had jobs like one stallion in particular, who was in his castle currently rearranging his library. His name was Dusk Shine. Currently in a purple tuxedo, he had a new shipment of advanced spell books he planned to donate to Mayor Mare and a donation of 120,000 bits for the renovation of a new school for Ponyville. His assistant Barb, and his personal student Starlight Glimmer, were helping him out in his library.

"Okay, that's the last box." Said Barb as she spread her reptilian wings out, glided down to the ground and set the box of books down. She was wearing a white blouse with blue jeans and a pair of sneakers that Rarity made for her. Starlight climbed down a ladder wearing blue jeans with a red blouse and hoof sandals. She carried a box in a lavender aura with some books.

"Yeah, I'm glad that's over." Starlight said as she set the last box down on the ground.

"Thanks again for helping me do this guys." Dusk said as he fixed his tie.

"No problem. I'm just glad we were doing something nice for the school." Starlight replied as she stretched her arms out.

"Well, I had a lot of old books that I hardly read anymore, and this should inspire more fillies and colts to read more often." Dusk added as he used his magic to bind a spell on the twelve boxes worth of books, which allowed Barb to use her fire breath to teleport them to Cheerilee's school. The group then walked out of his library.

"Are you trying to be as generous as Rarity?" Barb joked.

"Hey, all of my friends rubbed off on me" Dusk chuckled as he rubbed the back of his head. As they continued talking, Dusk suddenly stopped and groaned, as his body burned and seized up in immense pain. Barb and Starlight looked towards Dusk with concern in their eyes.

"Dusk, are you alright?" Starlight asked.

"Y-yeah...I'm fine... Just a little sore." Dusk panted as the burning only got worse.

"You don't sound like you're okay Dusk." Barb added as she walked closer.

"I-it's okay, I just… need some rest." He said as he backed away from Barb. Barb then noticed that his right arm was a darker shade of purple.

"You sure? Your arm isn't suppose to be that shade of purple." Dusk then tried to cover his arm.

"It's okay… I'm fine… just had too much sugar, that's all."

"Probably. Do you need us to bring you anything?"

"No I'll… I'll be fine." Starlight and Barb were pretty worried about Dusk but they eventually agreed with his decision. "Hey, how about you both take the… rest of the day off? Tell the royal guards that as well." He said to both his friends.

"Are you sure you'll be fine on your own Dusk?" Starlight asked, still a little worried about Dusk's condition.

"I'm sure I'll be fine..." Dusk responded as he started sweating.

"Okay, can we at least help you to your room? You still don't look so well." Starlight requested. Dusk was about to say something but groaned instead, as the pain got worse for him.

"N-no it's okay. I just need some m-medicine' that's all. I-I'll be fine..." Dusk stammered as he quickly ran to his room, leaving both Starlight and Barb confused. Dusk locked the door and flinched as another surge of pain coursed through him. Dusk looked up in his mirror and winced when he saw his pupils become slitted and his eyes turn from purple to red for a brief second before reverting back to normal.

'Crap... It's happening again.'Dusk thought to himself, realizing it was that time of the month. His dark secret he kept from his friends, his assistant, even from his student. 'They can't know what I really am.' Dusk said as he prepared to contain what was trying to escape from his body.

-Everfree Forest-

A silhouette of a black shadow roamed through the dark forest. It stopped at the old ruins of the Castle of the Two Pony Sisters and wandered inside. Six other figures seemed to have been waiting for the silhouette in the center of an old corridor. The shadow then took the shape of a mare as tall as one of the princesses.

"You all know why we are here?" The figure spoke in an ancient demonic tone towards the other six figures.

"Yes we do." Another female voice was heard but had more of a demonic monochrome.

"Revenge on a certain unicorn colt for out past defeats."

"He's actually an alicorn now, so don’t underestimate him."

"So his magical skill has increased since we last met."

"Indeed they have. Despite my last two attempts at conquering Equestria, his friends always got in the way. I even had a run in with his student."

"Really? Maybe we should use his student as a bargaining chip to get him to surrender his magic and the Elements of Harmony's Rainbow Power to us."

"I'm afraid we can't do that, even if we wanted to. The elements and their friends are on their way to Canterlot for a private party hosted by Celestia, so they are currently out of our reach."

"But Dusk isn't going. He stayed behind and he's all alone in the castle. Gave me an idea of something to add to our plan." One voice said, making the other shadows turn towards it.

"Care to explain?"

"Well instead of kidnapping one of the mares to lure Dusk, what if we kidnap Dusk and use him as a bargaining chip against Celestia?"

"Really?"

"We'll hold Dusk and harvest his magic, while informing Celestia and the other princesses to surrender all of Equestria to us, if they want him to be returned safely." An assortment of agreement from the group was heard.

"Then it's settled. We take Dusk as our hostage and all of Equestria will be ours."

-Castle of Friendship: 7:00pm-

Dusk waited for the last of his guards to leave the castle before he set his plan in motion. He drew a rune circle in his room and several candles were placed in certain parts of the circle. Dusk hung his tuxedo up in his closet. The only thing he had on were his blue boxers. After he made sure his wings were enclosed, he used his magic to create special symbols, to suppress his demonic side, along the circle. He groaned as another surge of pain suddenly coursed through his body again.

"Almost done..." Dusk said as he poured more of his magic into the sealing symbols. He was so focused on his spell, that he didn't hear the noises coming from the next room. The shadowy figures snuck in through an open window that Dusk had left open. He felt tired from using most of his magic, but he knew it was worth it. His magic surrounded the circle and now all he had to do was step inside. Sadly, things took a turn for the worse, as he felt something tap his shoulder, more like somepony. As he turned around, his face met with a frying pan, knocking him unconscious.

-30 minutes later-

"Ungh my head...What happened?" Dusk woke up groaning from having his face hit. He tried to move, but he felt his hands restrained. He looked towards his arms to find them chained to the wall. 'What the fuck?'

"Finally awake are you?" Said a female voice from in front of him. He turned around as seven figures stood in the shadows. Dusk couldn't help but notice that the voice felt familiar somehow.

"W-who are you?" Dusk stammered as he struggled in his bonds.

"Think back to your past victories against us." Another figure spoke. Dusk was scared but still confused.

"Still confused eh?" Said another figure only this one stepped out of the shadows as her green slitted eyes opened in the darkness. Dusk gasped as he recognized one of the villainous mares he and his friends defeated. Her black fur was shining in the dim light. Her slim yet curvy body was hugged by a tight green dress that seemed to show a little too much cleavage. The dress ended close to her knees showing off one of her toned legs. Her four limbs had a few holes and her long green mane was bound back in a tail, her wooden crown resting comfortably against her horn. The final tease was her green high heels.

"C-Chrysalis?" Dusk stammered, surprised at seeing her… then he became angry. He tried to use a spell but something was blocking his magic.

"Inhibitor rings, truly a great creation." Chrysalis teased.

"So you're back for revenge?"

"That's right, but this time I'm not alone." She smirked.

"What? You’re planning to invade Equestria again?" Dusk asked and all Chrysalis did was laugh at his question.

"Despite no longer having a loyal hive it’s only a minor setback. But like you, I have friends." Chrysalis then took a slight step back and the other figures stepped from the shadows. Dusk's eyes grew big as he laid his eyes on six other mares. One wore a jet black dress similar to what Chrysalis was wearing, but it ended at her lower legs. It had an opening on her right leg. She had ebony like fur with a mane and tail style similar to Rarity's but a darker shade. Her hip revealed her cutiemark that carried dark diamonds and her icy blue slitted eyes glared at Dusk. She had high heels as well, but hers were jet black.

"N-nightmare Rarity..."

"I'm so glad you remember me darling." She spoke in a rather saucy tone.

Dusk looked at the other two mares next to her. Clad in dark blue armor, designed more for sex appeal than protection, adorned her black-coated form. Her midriff was bare, as were her hips, which allowed her Cutie Mark to be seen. A blue metal bustier covered her chest, a blue metal codpiece covered her crotch, her hands and hooves covered by stylishly armored gauntlets and pauldrons. The mare next to her had the same armor design but her gauntlets and pauldrons were a silver color. She had red slitted eyes and her sclera was green with purple smoke. Her horn was red, she had a coal black mane with grey coat and her cutie mark resembled dark crystals, almost like a small nest sprouting out.

"Umbra and Nightmare Moon!"

"Rather interesting to see you in your underwear, you whelp." Umbra said as she walked over to Dusk and used her armored hand to scratch Dusk's right cheek. He groaned as his cheek slowly dripped blood.

"And they aren't the only ones here." Another feminine voice spoke up. He met them during his time in the otherworld behind the mirror. One had a luminous vivid orange mane with bright yellow streaks. Her eyes were a raspberry color, and her coat was a pale apple green. She had her dark purple blouse, dark purple shorts with pink jacket, fingerless gloves, fuchsia leggings with purple triangles and dark purple boots with golden spike anklets. The second one had a light arctic blue mane and tail with moderate persian blue stripes tied in a ponytail. She had the same colored eyes as her friend but her coat was pale blue. She wore a dark purple collared shirt, with pink skirt, wore spiked pink wristbands, and thigh high sneakers. The third one had moderate mulberry eyes, a pale coat with a light grayish fuchsia color, and her mane and tail were a moderate purple with light aquamarine streaks tied in pigtails. She had a pale green shirt with a dark green jacket with the sleeves cut off, purple jeans, a belt with a star buckle, violet boots, and black wrist bands.

"The Dazzlings?"

"Aria, Sonata and Adagio. Nice to see you again Dusk." Adagio cackled. Dusk looked behind Sonata to see her holding a frying pan behind her back. Dusk was furious at seeing the cookware, then noticed from how he was chained up that he could clearly see Sonata's creamed colored panties. He then started blushing.

'Why is she wearing those anyway?' Dusk thought to himself. Dusk was soon shaken from his thoughts as he felt the wind knocked out of him when a fuchsia colored hoof kicked him in the gut. He wheezed and looked up in pain to see an angry Aria Blaze glaring at him.

"The fuck are you staring at pervert!?" Dusk flinched at the comment. He then noticed that he had a hard-on. Aria then ground her hoof on his member, causing him to groan in agony.

"What was that for?" Dusk groaned, causing Aria to grind her hoof harder, causing him to groan louder in pain.

"That's for letting your eyes wander where they shouldn't." She growled as she causes more pain to Dusk's pelvis.

"That's enough Aria, we need him intact remember?" Nightmare Moon stated. Aria reluctantly removed her hoof from Dusk's pelvis. Dusk heard her grumble the words 'lucky bastard' as she walked back to her group.

After recovering from the pain, he started asking questions. "You were in the Mirror World, how are you here? As a matter of fact, how are all of you here? Umbra was destroyed and the Nightmares aren't supposed to be able to have physical forms without a host."

"Umbra brought us back here." Sonata chirped.

"How is she, Nightmare Moon, and Nightmare Rarity back?" Dusk asked a little annoyed.

"I had little to salvage after your student made me lose my kingdom. I swore I was going to get revenge on her as well as you and the rest of your friends. After dealing with her, perhaps I’ll turn the rest of your friends into broodmares and have you as my personal… servant, that would have to follow my every command. Unfortunately, I had to recover from my losses and had to stay hidden in the shadows to scour all of Equestria for anything to use as a temporary source of food until I was strong enough to capture and feed on the emotions of ponies again."

"Why didn't you--?" Dusk got slapped across his muzzle by Chrysalis before he could finish his question.

"Don't interrupt!" Chrysalis shouted in his face. "Now where was I? Oh yes. I spent most of my time studying the Crystal Empire and found a cavern to hide in as I spent my time collecting as much love as I could from the Crystal Ponies. One of the things that I came across was a red crystal shaped like a horn. I could not figure out anyway to use it, so I tossed it with the rest of the used or useless junk. All of a sudden, a dark aura surrounded the crystal and soon spread through the cave I was hiding in. I felt my strength fading as a black shadow began to emerge from the crystal, and I was growing weaker as much of my energy that I harvested was being drained. Once the aura dissipated, a grey unicorn, who I would soon learn was named Umbra--"

"Queen Umbra!" Umbra interjected to correct Chrysalis.

"Queen Umbra." Chrysalis amended, "Too weak to do anything, I laid helpless as Queen Umbra blocked all exits with black crystals and lifted me off the ground by my throat. She demanded to know where we were and I told here that we were in the lower catacombs of the Crystal caverns. She then dropped me and proceeded to use some… colorful language to describe what she wanted to do to the Crystal Princess and some dragon."

At that, if anyone was looking at his eyes, they would have seen them go red, but only for a second.

"Upon thinking about it," Chrysalis continued, "I seemed to have remembered the whelp of a dragon that was your assistant, and proceeded to describe her. Queen Umbra demanded to know who and where she was. I told her what she wanted to know, plus a little bit extra."

Umbra continued from there. "Like the dragon being your ward and that Crystal Princess was your in-law. I originally wanted to go after them immediately. However, I soon realized that would be easier said than done. So we made an alliance to combine our might and strengthen our forces, and bide our time for the perfect opportunity to grab you, your dragon, or that usurper to my throne. But to do that, we needed to move closer to our quarries."

"So we chose the long abandoned Castle of the Two Sisters." Chrysalis continued. "While scouting to make sure there would be no surprises, the few changelings that stayed under my command, until recently, found two unusual items; a black diamond and a piece of armor with a dark crescent moon."

"I immediately sensed a dark presence in each item. With the proper spells, I was able to--"

Nightmare Moon gave a loud exaggerated yawn. "Can you just wrap this up? I am getting bored."

"Oh, I can do it!" Sonata volunteered, before Adagio covered her mouth. "Nevermind her, continue." Adagio said.

Umbra growled while looking at Nightmare Moon. "Fine!!" She yelled, "Why don't you wrap this up?!"

"Very well," Nightmare Moon then proceeded to summarize the rest. "Me and Nightmare Rarity were revived by Umbra and when we fashioned a makeshift portal to look for more allies, we found these former sirens--"

"Hey!" the Dazzlings interjected in unison.

"--after which we were able to break Starswirl's curse on them that prevented them from returning to Equestria, and here we are." The dark alicorn continued as if she wasn't interrupted.

"What do you all want from me?" Dusk groaned in anger and pain, wondering what they were planning. Umbra then walked over to him and grabbed his face.

"Well for starters, revenge for our past defeats." She responded. As she walked away, with a sway in her step, back to her group, she continued. "But we're also going to use you to help us conquer all of Equestria." She stated while smirking.

"And why would I want to help you do that?" Dusk asked, causing Chrysalis to cackle.

"We will be siphoning your magic to increase our own. We will also be using you as a bargaining chip to get the princesses to surrender Equestria to us. Plus without you, they can't use your Rainbow Power. Nopony would be able to stop us."

"How do you plan on siphoning my magic? You'd need a specific rune circle to do that." Dusk added. The villainous mares chuckled at his response.

"You practically did that for us." Moon stated, as she pointed to the red circle Dusk created. Only the rune symbols were replaced. Dusk was now nervous as he just remembered why he had that circle there as he felt another surge of pain course through his body.

"We'll have to wait till tomorrow. He just used most of his magic to make this rune circle for whatever reason." Chrysalis pointed out as Dusk started to struggle in his bonds to try and get loose.

"Don't even bother, they're magic chains. We even had a fail safe put in to keep you from using your magic to escape." Nightmare Rarity teased. "Not to mention that we placed an invisible force-field around your castle.”

"You guys siphoning my magic isn't what I'm worried about right now!" Dusk stated. He groaned as the pain throughout his body got worse.

"What are you trying to pull, you whelp?" Umbra growled. Sonata then noticed a set of sharp fangs growing in Dusk's muzzle.

"Uh...are his teeth suppose to look like that?" She asked, getting the attention of her siren sisters. The other four heard her as Dusk writhed in agony as his body burned in immense pain.

"The fucks wrong with him?" Aria Blaze asked as they all looked at him. Dusk soon opened his eyes to reveal that they became red and that his pupils were now slitted.

"The fuck was that?" Adagio asked as Dusk began to undergo his transformation. The seven mares watched in awe and confusion as a black aura suddenly surrounded him. After twenty seconds, the aura that surrounded Dusk began to dissipate, and he slumped to the floor. All seven mares then noticed that his body grew at least an additional two feet in height, his wings and coat grew a darker shade of purple, his hooves turned black, and his hands became a set of sharp black claws. What made him stand out the most were the two sharp horns that appeared on the sides of his head. He stood up, broke the chains off his arms, and cricked his neck, groaning slightly as he looked behind him.

"Well, this is a rather interesting surprise." Said the new figure that now stood before the seven villainous mares.

"Is that suppose to be Dusk?" Sonata asked the others, who were just as confused as they were.

"It doesn't sound like him. His voice sounds demonic." Chrysalis pointed out.

"I assure you that I am Dusk Shine. Just in a different form. One he prefers to keep hidden." Dusk stated, as he licked his lips for what he had planned for his corral of playthings.

"What form is that anyway?" Umbra asked. Dusk then smirked.

"I'm afraid you'll have to catch me to find out." He chuckled while looking the group, just before he vanished right before their eyes?

"Crafty little weasel!" Adagio growled.

"Split up. If he finds a way out of the barrier and goes to Canterlot, our plans will be ruined." Umbra barked and they all split up to find their target. What the pursuers were unaware of, however, was that they were now the prey, and Dusk was stalking them as he lurked from the shadows.

"Decisions, decisions. Who do I go after first?" Dusk said to himself as he flexed his wings slightly. He was in another room at the time.

"They all have well developed bodies, especially Umbra and Nightmare Moon." He pondered for a bit until the sounds of rapid hoof steps came running towards him. He turned himself invisible as the door to the room he was in opened up. Three figures appeared in the doorway.

'The Dazzlings… so you all came looking for me, have you?" Dusk thought as he listened in on their conversation.

"That little bastard!" Aria yelled as she punched a nearby desk.

"Didn't think we'd be looking for him." Adagio stated.

"Um girls..." Sonata spoke up causing Adagio and Aria to look towards her.

"What?" They both said in unison. Sonata tried to speak up, but couldn't find any words to say.

"N-nevermind. It's nothing." She said earning annoyed expressions from her sisters.

"You do realize we need to find that little prick to fix our amulets right?"

"If you aren't going to help us, then just wait here. We'll find him." Aria and Adagio then left their distraught sister in the room they were in.

'You didn't have to yell at me. I just have a really bad feeling.' She thought to herself as she slumped on a random chair, tears starting to stream down her pouting face.

'Well, that wasn't very nice of those two now was it?' Dusk thought to himself as he pitied Sonata. Pity was soon replaced by lust, as he smirked and licked his lips. Sonata was now alone and ready to become his first acquisition. 'Don't worry Sonata, I plan to make you feel all better before this night is done.' He chuckled to himself as he slowly crept up behind Sonata Dusk.

Author's Notes:

Hey folks. This idea has been stuck in the back off my head since I got back on recently. The seven villainess mares are gonna regret kidnapping Dusk on a full moon night. I'm not sure if I got The Sirens clothes right so just bear with me.
