Cozy Glow's mind possessed and controlled the body and mind of Luster Dawn. With the power of Grogar's bell by her side, she stood against Twilight Sparkle, Starlight Glimmer, Trixie, and Flurry Heart.

On the plains of Equestria, the battle raged on. It was Cozy Glow, controlling the mind of Luster Dawn, with the power of Grogar's bell in store.

The four 'corns leaped into action. They charged forward, but Cozy pointed the bell, not at them, but upwards.

Cozy leaped into the air, and charged her horn.

*BOOM*

The 'corns blocked her blast.

Flurry Heart flew forward with her magic poised and ready, but Cozy was done playing around. Now she was serious.

*RING*

*AAGHH!* Flurry cried.

Cozy activated the bell, and a powerful vortex leached onto her horn, and depleted her of her magic.

"And now-"

Cozy flipped the bell over which sent Flurry up and over and-

*SLAM*

She slammed Flurry to the ground.

"FLURRY!" The others exclaimed.

Cozy pointed the bell at herself, and a beam of magic shot into her, and she absorbed Flurry's alicorn magic. Without chaos magic to interfere, she was able to take full advantage of the alicorn magic.

The surge in extra magic made Luster appear more powerful. She grew fangs, and her hair became more fiery.

Luster Cozy slowly walked to the downed Flurry.

"Thank you, Flurry, my love." *smooch* Cozy kissed Flurry's forehead.

*poof* Cozy made Flurry disappear for convenience.

"Any other magic donors want to step forward and contribute to my great cause?!" Cozy exclaimed. "Or are you too scared I'll do the same to you?"

Starlight and Twilight were hesitant, But Trixie was steadfast.

"Trixie shall not be intimidated!"

Trixie activated the alicorn amulet, and her magical abilities grew in strength. Trixie ran forward and charged Cozy fired a blast of magic, but Trixie easily deflected it with a magic shield. The alicorn amulet made her surprising powerful.

"Wow, Trixie, you're no slouch. Especially with that juicy looking amulet..." Cozy's mouth watered at the thought of that amulet.

The two chased each other around. Trixie withstood one of Cozy's beams. Though Trixie's defenses were tough to penetrate, Cozy went in for the magic.

"Trixie's hit!"

Trixie fell to the ground. Cozy snatched the amulet from Trixie, and-

*SHATTER*

She threw the amulet to the ground, and stomped on it, destroying the amulet, and releasing all of its magic. Cozy rung the bell and absorbed the magic from Trixie and the amulet.

"Any more smart-ass comment, Ms. Lulamoon?" Cozy exclaimed.

"Uh-"

"Nope!" Cozy exclaimed.

*poof*

Trixie disappeared.

With Trixie and Flurry Heart defeated, that just left Twilight and Starlight.

"Stop this right now, Cozy Glow!" Starlight cried. "This has gone on long enough!"
"Release Luster Dawn at once!" Twilight cried.
"Never! She's mine now!" Cozy declared. "Luster has literally given me the time of my life!"

"You can hear me, Luster! You got to fight it!" Twilight exclaimed.

"Pfft. That only works in fiction. Luster can't hear you." Cozy explained.

"Oh, help me! Twilight, help!" Luster cried.

"Luster Dawn!"

Cozy pretended that Luster Dawn was breaking through, but it was just pretend.

"Just kidding! I'm in full control of Luster!" Cozy exclaimed.

"We need to rethink this, Starlight. Before any other pony gets hurt!" Twilight said.

But it was too late, Starlight already made her move.

"That's it!"

Starlight had lots of anger bottled up, but now she was ready to unleash it. Starlight ran forward, and fired magic shots are Cozy. Cozy flew the other way as Starlight chased her.

"You're no match for me, Glimmy!" Cozy said.

Cozy spun around, faced Starlight, and fired magic at her. Starlight leaped and dodged the onslaught, but she only had so much energy, and she was

"I'll admit this, you were always my favorite counselor." Cozy said. "After all, you made a great instigator for my spell!"

Glimmer leaped up, shot beams of magic, but Lust Star was fast! Soon she was overwhelmed by Cozy's immense magical power. Cozy zipped and zoomed, and brought Starlight to the ground. Cozy put Starlight in a magic bind to hold her in place.

*ERGH* "Stop it! Don't!" Starlight cried.

*RING*

Cozy drained Starlight of her magic, and immediately absorbed it for herself.

"You have to stop!" Starlight pleaded.
"I will stop soon. I have just one pony left." Cozy said.

*poof* Starlight disappeared.

"And then there were two." Cozy said. "Oh this is going to be fun!"

It was just Twilight Sparkle against Cozy Glow, possessing the body of Luster Dawn.

"Cozy Glow!" Twilight cried.

*zap*

Cozy fired a beam of magic at Twilight, which Twilight intersected with her own beam

*BOOM*

Twilight fired a magic beam at Cozy, but it was completely ineffective. Cozy took pleasure that Twilight's magic was basically useless against her.

"It's no use, Twilight. My power far exceeds yours! You can't defeat me with brute force magic!" Cozy exclaimed.
"She's right, I can't defeat her magic. I need to break through to Luster, but breaking down Cozy Glow." Twilight said to herself.

It was then that Twilight finally decided that the best thing to do was to talk to Cozy Glow.

"Cozy Glow, please, I-" Twilight started.
"You what?" Cozy cried.
"Release Luster Dawn, she didn't do anything to you!" Twilight pleaded.
"That's where you're wrong, Twilight. Luster Dawn (hold your breath), offered to HELP ME! Which is a lot more than you or any other creature can say!"
"Is that all you wanted, Cozy? Was help?" Twilight asked.

*hoof palm*

Cozy faced palmed Luster's face.

"Not saying I would have accepted your help, but gee. But fucking anything beats a life sentence in Tartarus!" Cozy exclaimed. "All because I threatened your precious magic! Which you're about to lose anyway!"
"I asked you why,

"What part about friendship is power didn't make sense? But did you ever wonder why a filly was so obsessed with power? Not enough to ask any further questions! You were perfectly content with sweeping your problems into Tartarus, and calling it a day!"

"You can forget about reformation! I wouldn't be caught dead following your hoofsteps, Twilight." Cozy said. "You took everything from me, Twilight! Now I'm going to take away everything you care about. I already took your student, Luster! Now for your magic!"

"Please just let Luster go!" Twilight pleaded.
"And then what? Without a vessel, are you just gonna let Cozy's soul pitter patter into oblivion?!" Cozy exclaimed.
"What are you talking about, Cozy?" Twilight asked.
"Why do you think I had to take over Lusty? You think this was my first choice? Frankly, no, if for no other reason than Lusty is way less pretty than me."
"Let's just say my sister isn't the only Cozy to die." Cozy said.
"Cozy!?"
"As if you care! You barely cared when you thought Cozy was gonna lose her head!"
"I'm sorry, Cozy! I wish I could have help!" Twilight shouted.
"See. NOW you want to help. Now you feel sorry, now that I'm GONE! Way to go Twilight, you waited too long. You didn't reach out when I needed it. And it only cost me my livelyhood. My body's gone! Lusty's all I have left..." Cozy's voice
"Cozy, I." Twilight started.
"Where was your melodramatic speech when I needed it!?" Cozy exclaimed. "You locked me in Tartarus, you put me in stone. Did you honestly think your punishments wouldn't have a drastic effect on me?!"

Lust Star slashed her horn in the the air, ripping a scar in the air, that opened and fired bursts of magic at the co.

Twilight's magic shield was only barely strong enough o block the onslaught of magic.

Cozy was not letting up. She was more furious than ever, and continued her assault on Twilight Sparkle.

"If you stop attacking right now, I will reconsider!" Twilight exclaimed.
"Is this your form of surrender?" Cozy asked.
"You are right, I could have prevented this all from happening." Twilight said.

Twilight landed on the ground, and her horn stopped glowing.

"Come on Cozy, we can start over." Twilight said. "If you stop all of this, I'll listen to what you have to say. We can work through this situation and find a solution."
"Need I remind of you of the misery you put me through, Twilight?" Cozy asked. "Where was your sentiment when you and Equestria's leaders unanimously decided to lock me in Tartarus! Or when you decided the best place for me was sealed away in stone?! You only feel sorry for me now that you now what loss feels. I took away your student, and you want her back. Only now are you listening to me. Absolutely pathetic."
"You were my greatest failure Cozy Glow!" Twilight admitted. "It is my job to spread the message of friendship! But I failed you! I couldn't show you the meaning of friendship!"

Cozy was not impressed by Twilight's melodramatic speech. So she wanted to see if she really meant what she said.

*poof*

Amber Glow appeared in front of Twilight.

"Say that to her face." Cozy demanded. "Prove that you can feel real sentiment for Cozy!"

Amber wasn't dead, although she was bloody and bruised. She was conscious however.

"You're princess Twilight Sparkle?" Amber said, faintly.
"Yes I am. I- And are you Cozy's twin sister?" Twilight asked.
"Why? Why did you hurt my sister?" Amber asked. "Why did you seal her in stone?"
"I couldn't let Cozy go unhinged. She was going to destroy all the magic, and-" Twilight explained, but was interrupted.
"She's just sad. Our daddy was mean to her, so she came to your school for salvation." Amber Glow explained.
"AAHH!" Amber cried, when something hit her from behind.
"Cozy! Or, err. Whatever your name is!"

Cozy Glow froze Amber Glow in stone.

"What's the matter, Twilight? I thought you were okay with putting Cozy Glow in stone!" Lust Star exclaimed. "My sister's no saint either, she tried to attack you too."
"Cozy, I-"
"Take a good long look at the sad child!" Lust Star ordered. "Do you feel sorry for her now? Do you want to reach out and help the filly now? You went through so much trouble to bring Princess Luna back from Nightmare Moon. You reformed Discord just because Celestia told you to. You begged and pleaded at Starlight Glimmer for her to turn over a new leaf. You argued against your idol, Starswirl, to reform Stygian. And what did you do for Cozy Glow?! WHAT DID YOU DO TO COZY GLOW?!"

Twilight closed her eyes and wept.

"I failed her." she said.
"Yes you did." Cozy affirmed.

Lust Star took out a big sledgehammer

"The shame about being immobile, not being able to defend yourself." Lust Star pulled back the sledge hammer. "It leaves you especially vulnerable to vandals!"

Cozy was read to swing the sledgehammer.

"Cozy Glow is dead! She's dead and it's all because of your negligence!" Lust Star exclaimed.

Cozy swung the sledgehammer, but Twilight leaped in front of the statue, but Cozy wasn't aiming for it anyway. She was aiming for where Twilight Sparkle was.

*MAGIC*

"What, you didn't think I'd shatter my own sister, did you?" Cozy asked.

Twilight looked every befuddled.

"Hmm, you tried to defend Cozy while simultaneously assuming Cozy Glow would commit homicide." Cozy said.
"I don't know who is who anymore!" Twilight cried, confused, and shocked.

Cozy lifted, and then dropped the sledgehammer.

"You did good, sister." Cozy whispered to the statue of Amber.

*poof* the statue disappeared.

"I'm sorry, Cozy Glow." Twilight apologized. "I had no idea you were such a miserable pony." Twilight said.
"Of course you didn't. You never asked me WHY I wanted all the magic in Equestria gone!

Cozy walked forward, and Twilight backed up in fear.

You don't know the beginning of my misery! You think you have it so rough, when you had everything going in your favor! Then there's me, where every possible force of nature tried to oppress, or kill me! But while you had your princess duties handed to you, I had to earn my powers! The universe tried to kill me, and it succeeded! You can kill Cozy Glow, but you can't get rid of Cozy Glow so easily! I always find a way to come back! And look at me now! I'm the most powerful creature in the entire world!"

Twilight fell over in fear.

"Alright, I've had enough. Time to end this." Cozy said, holding the bell by her side.

Twilight tried to defend herself, but Cozy walked up slowly, and forced Twilight to the ground.

"You were wrong, Twilight. Friendship isn't magic. Friendship is power! And now, I have all the power in Equestria!" Cozy exclaimed. "And now, you will be fortunate enough to contribute to my power."

The bell rang, and the beaming vortex latched onto and sucked the magic out of Twilight Sparkle. Twilight returned to her plain old short unicorn form. A form she hadn't had since before she got her wings.

"This is what happens when you give a masochistic child all the power in the world." Cozy said. "God tried to kill me, multiple times! And he had good reason to! But you can't keep me away! I will always come back! To torment!"

Cozy stood tall, showing off the fact that yes, she controlled Luster Dawn, and made her into a powerful alicorn.

"Take a good look at this. You created this. You enabled me to rise to power!" Cozy exclaimed. "You lose, Twilight Sparkle."

"I hear you're good with words, Twilight. You reformed Starlight Glimmer with nothing but empty promises and lies. So please, if you think you can talk yourself out of this, then go ahead and try!" Cozy smirked.

"I've got nothing..."

"Well, that makes this easier then.

Cozy conjured

...*ERR* AAHH!" Cozy exclaimed. "Why isn't this satisfying! I literally accomplished everything I set out to do! I fulfilled my parent's wish and became the most powerful creature in Equestria. I fulfilled my number one objective and defeated you! I humiliated you, and took advantage of your student. Here I am about to slay you for good, but why does it feel so EMPTY!"

Cozy breathed heavily.

"It feels like... something's missing..." Cozy said.

If there's one thing that can be said about Cozy, Twilight definitely recalled Cozy having fun during their battle before her coronation. This Cozy was the opposite of that. She was alone, and very vengeful. In spite of achieving her goals, she definitely lost more than just her body along the way. Twilight saw an opening.

"You mourned your sister when she got injured. That means you really care about her. And I know she's not the only creature you care for." Twilight said.
"What does that mean?" Cozy asked.
"I didn't see it before, but now I realize, you're not as evil as most other villains." Twilight said.
"What makes you believe that?" Cozy asked.
"Most other bad guys want to conquer Equestria for themselves. But you, you're doing it so you can be together.
"UGH! Dammit! How do you know?!" Cozy asked.
"I can sense what you're thinking. The thing you want most, is to be reunited with your friends." Twilight said.

Cozy was about to finish Twilight, but she couldn't...

*hrrgh* "Fine! I admit it! Chyrsalis and Tirek are my friends! Okay! I said it!" Cozy wept. Tears poured down Luster's eyes. "You know what friendship, it isn't so bad after all. Helping out others and them helping you in return is a nice feeling!"
"You're starting to see the light, Cozy Glow." Twilight said.
"But you! You have taken friendship and misconstrued it in the worst possible way! I refuse to suck up to you!" Cozy defied.
"You don't have to take my word for it. Look around, Cozy. Reflect on what you've done. Is this really the outcome you want?" Twilight asked.

Cozy looked at her hooves, but they were Luster's her identity was gone.

"I can't undo all the damage that's been done!" Cozy wept. "My body's gone! My sister's gone! I'm Equestria's most hated creature! But I don't care what others think of me. I just want *sniff* I just want to see my friends again..." Cozy wept.
"What are you going to do, Cozy?" Twilight asked.

*stomp*

The ground shook, and they heard a loud thud from the distance. Cozy came to life with excitement.

"I'm not going to do anything to you, Twilight." she said.

Twilight looked over the vista, and she saw him. Lord Tirek. He had finally arrived onto the scene, fully loaded with magic, and very large. About as large as his largest size seen in the show. But he also had a very... dark aura to him.

"What is that?!" Twilight exclaimed.

*Shh* "Close your eyes, Twilight. And everything will be all better once you open." she said.

*poof*

Twilight Sparkle was gone.

"So, Tirek decided to unleash the Rainbow of Darkness anyway. Kinky." Cozy said.

Cozy was over the moon excited to see that Tirek had finally made it here. She casually flew right over to him to greet the centaur.

"It's good to see you again, big guy." Cozy said to herself.

Tirek had a very grumpy look on his face. He looked around, befuddled at what he saw.

"...What is this?" Tirek asked.
"I-I I don't know what you mean." Cozy said.
"You dare to have the audacity to approach me directly!?" Tirek asked.
"I-I I still don't know what you mean." Cozy said.
"You're that little unicorn student of Twilight's. You've come to stop me in my tracks." Tirek said.

Cozy looked at her hooves, she still looked like Luster Dawn.

"Oh! No no no. Tirek, you got it all wrong, it's me! Cozy Glow! See, look!"

*poof*

After a poof of magic, Cozy still looked like Luster Dawn.

"Is this supposed to be humorous?" Tirek asked, with anger.
"Uh, let me try again." Cozy said.

*poof*

Cozy tried to transform, but no matter the spell she tried, she still looked like Luster Dawn.

"I don't know why this isn't working. But I swear, Tirek! It's me! Cozy Glow! Really!" she pleaded.
"No, that's impossible. Cozy Glow is right here..." he said.

Tirek held his fist out to Cozy, and slowly opened it, revealing he held Cozy's corpse.

*gasp* "You weren't supposed to see that..." Cozy wept.
"The most vile, despicable, and diabolical pony in modern Equestrian history. She was everything I ever could have wanted. *sniff* But now she's gone..." Tirek said.
"No no no, Tirek! I swear this isn't what it looks like!" Cozy pleaded.
"No, this is exactly what it looks like." Tirek said. "You kill off the only pony I ever cared about, and you have the audacity approach me!? And pretend to be her!?"
"But it's really me! Tirek! Remember! We ran away and started our own village called TCGC! We built a machine to find the Rainbow of Dark-*gasp*

Cozy noticed the darkness was slowly creeping around Tirek.

"Remember Chrysalis and her pathetic princess act? Remember climbing Mt. Everhoof together! Remember laying siege to Twilight Sparkle with Grogar's bell by our side? Luster wouldn't know about our times together!"
"C-Cozy?" Tirek asked.
"Yes, it's me, big guy." Cozy replied.
"Cozy? I-*ZAP*AAAHHHHH!"
"Tirek!" she exclaimed.

Tirek was fully consumed by the darkness.

"Tirek! Can you hear me?! Tirek?!" Cozy exclaimed.
"The Tirek you knew was a shell of his former self." a sinister new voice came from Tirek.

*gasp* Cozy gasped.

The Cozy corpse twitched, its eyes opened, and glowed a terrifying purple glow.

"Lord Tirek was destined to conquer Equestria, but then you came along, and showed him friendship. You turned the mighty centaur into a pansy on a little mission to save his girlfriend. I'm simply here to put Tirek's on track."

Cozy had recognized that voice. It sounded just like the voice of Grogar!

"Stop it! You're hurting him!" Cozy exclaimed.

"Tirek deserves better."
"You hurt Tirek."
"Join us, Cozy."

A lot of shadowy creatures surrounded Cozy Glow. She immdiately recognized them as her friends from the village. Suri Polomare, Lightning and the Washouts, Svengallop, and so on. All had been turned into hideous shadowy creatures.

"What have you done to my friends?" Cozy exclaimed.

Tirek charged up his magic. His large horns glowed red, and a ball of energy charged in the middle of the horns.

"You killed Cozy Glow, so now I am doing to kill yoU!"

"Tirek, no! AAAHHHHHH!"

*ZAP*

Tirek zapped Luster's body with a massive magic beam. The blast sent Luster's body flying away at great speeds.

*boom*

They crashed into the side of a mountain, leaving the centaur and spirit of the Rainbow of Darkness to themselves.

"Thank goodness she's gone." Grogar said. "This kingdom is now mine once again."
"Wait." Tirek said.
"Hmm...?"

The mountain side was glowing. There was still great power emanating.

*boom*

Luster Dawn emerged from the mountain with glowing colors. She was fully charged with all the magic she'd gathered. She hovered in place, and poised fighting ready, and was ready to take on Tirek and the Darkness.

"No dark energy is going to control my friends!" Cozy exclaimed.

*zip*

Cozy Glow flew towards Tirek at breakneck speeds. She wasn't going to let the Rainbow of Darkness turn Tirek and the rest of her friends into mindless creatures.

To be continued...
