Story - Three-on-One Showdown! Fight for Princess Luna!
 
Summary: During the night at Canterlot, Daybreaker and Nightmare Mare manipulate Princess Luna and they make her work for them so they can defeat Princess Celestia the next time they see her. The next morning, Princess Celestia finds out about this, and, however, she realizes that the only way she can have her sister back is to defeat Daybreaker and Nightmare Moon once again.
 
All the ponies have been sleeping during this night in Ponyville and also Canterlot. But one pony, Princess Luna, has been having trouble sleeping as she couldn’t she stay asleep and was worrying what is going on outside.
 
“I should really go out and see what’s happening.” Princess Luna said, flying out the window and make sure that something was not becoming a problem right now.
 
Princess Luna was flying in the night, looking at Ponyville way down below her, noticing not a single pony was awake at this moment. “Everything seems fine, and it appears no danger is happening right now…” Princess Luna said, looking nervous, though, that it may not be true.
 
However, while she was flying still, two ponies in the shadows flew past her very quick and couldn’t even see who the two ponies are.
 
“Wh-what was that?” Princess Luna wondered, getting suspicious that she feels like she is seeing suspects are on the run. “Whoever just flew right past me without slowing down, show yourselves!”
 
“Right, hello, Luna…” A voice called from behind Princess Luna, which has caught her attention. When she turned around, she shocked and saw Daybreaker and Nightmare Moon, who want a talk with her, whether she wants it or not.
 
“I hope you didn’t miss us.” Daybreaker told Princess Luna, putting her hoof below the latter’s chin. “It is a shame that you are having nightmares about us yet again.”
 
“Impossible! I thought you two were dead.” Princess Luna replied, as she already knew that her older sister destroyed them both when they met the first time.
 
However, Nightmare Moon reminded her good counterpart, saying, “I know, but Celestia didn’t destroy us forever, so you can only blame her for doing such a job that was actually not a success. You thought we’ve been gone forever, but we can never disappear. We are goddesses, and we shall not be defeated again!”
 
“In fact, we have something for you as a favor so that we don’t lose again.” Daybreaker told Princess Luna, as she has something for the latter that will make her do the bidding for her and Nightmare Moon, one way or another.
 
“What do you mean by that?” Princess Luna asked, not understanding what Daybreaker meant when she said that they want her to do them a favor.
 
“You’ll be serving us, and help us destroy Princess Celestia, just like how she did towards us both!” Daybreaker replied, knowing that having Princess Luna as a more useful servant was her most perfect opportunity.
 
Princess Luna crosses her hooves, declining, “Never! I’m never gonna be working for any villain, especially for two ponies who are the opposite of me and my sister!”
 
“Bad choice. Guess we better force you, then.” Daybreaker said, letting Nightmare Moon manipulate her good counterpart with a spell called the “Manipulation Spell”, which a certain villain can control the hero or heroine and they force them into doing every single favor.
 
Under Daybreaker and Nightmare Moon’s command, Princess Luna changed her mind, and would help the two destroy Princess Celestia forever.
 
“That’s more like it.” Daybreaker said, seeing Princess Luna with a smile on her fact and that it tells Daybreaker and Nightmare Moon that she will help them with whatever they need for her to do.
 
“Come on, let’s hide somewhere in Canterlot.” Nightmare Moon told the two ponies, as they all head straight for Canterlot, planning on hiding somewhere in the back so that Princess Celestia’s guards don’t catch her and Daybreaker with Princess Luna.
 
The next morning, Princess Celestia was in her room waking up from her nap, having her usual good sleep. Just when she was gonna go towards the hallway, two of her guards have came rushing in, informing her about what has happened.
 
“Highness!” said the unicorn royal guard, looking particularly exhausted.
 
“Is something the matter, my guards?” Princess Celestia asked putting her hoof under the unicorn royal guard’s chin, and wants to know what the situation was about.
 
“Yes, your highness.” The pegasus royal guard responded, who was also looking tired. “We have noticed that Princess Luna has been missing since last night, and we’ve tried searching for her all over the castle inside up until this morning about the past hour, but now we can longer find her.”
 
Princess Celestia gasps in horror over what her guards have told her, not aware that Daybreaker and Nightmare Moon have taken Princess Luna with them. “But did you search outside, though?” Princess Celestia asked.
 
“No, we have not.” The pegasus royal guard replied, leaving Princess Celestia suspicious.
 
“However, we did heard news that Nightmare Moon took Princess Luna with her. And we also noticed that there was another pony around last night, but we can’t identify who she is.” The unicorn royal guard added, as he and the other guard had been watching from the window last night and saw Daybreaker involved in this situation.
 
“Wait, you don’t mean?” Princess Celestia asked with a worried look on her face, as her guards are telling that the pony they are talking about was actually her dark side counterpart, Daybreaker.
 
“Yes, her name is Daybreaker.” The unicorn royal guard responded, finally telling Princess Celestia about the other pony involved behind the back last night outside.
 
Princess Celestia, feeling frustrated over her sister being gone, said, “How dare those two take away my sister?! If I even find Daybreaker and Nightmare Moon outside, they are gonna pay for good!”
 
“Hurry back soon, princess.” The guards told Princess Celestia, as she would go on her alone and search for her sister and bring her back.
 
“I don’t know where she is right at this moment, but I can’t let my sister be forever gone.” Princess Celestia said, knowing that her sister shouldn’t have let the castle without telling her, and that is her responsibility. “I’m gonna save you, Princess Luna, no matter what I do…!”
 
However, despite being in the sky, Princess Celestia didn’t see Daybreaker, Nightmare Moon, and Princess Luna anywhere in her sight.
 
“Down below!” A voice called from below very loud, grabbing Princess Celestia some attention. And so, with that, Princess Celestia flies down back down towards Ponyville, and when came down, she was shocked that Princess Luna was with the two, unaware that she is under Daybreaker and Nightmare Moon’s command.
 
“It’s about time you came here, because we’ve been almost getting one-hundred percent bored.” Daybreaker told Princess Celestia, considering the latter arriving late from what she was expecting.
 
“Luna, why are you with them?” Princess Celestia asked her youngest sister, curious about why her sister is joining Daybreaker and Nightmare Moon.
 
“There’s no need to ask her that part. She’s with us so that we can destroy you forever, just like how you tried the same with us before, and we owe you that favor back.” Nightmare Moon responded, as her good side was helping her and Daybreaker so that the fight could be at odds.
 
Princess Celestia threatened Daybreaker and Nightmare Moon, telling them, “If you don’t return my sister back, I’m gonna tear you both apart and I’ll make sure you both are destroyed for good!”
 
“Only if you can defeat us both, that is.” Daybreaker laughed at the response Princess Celestia said towards her. It isn’t gonna be easy, though.”
 
“Like she said.” Nightmare Moon added, letting Princess Celestia know that three ponies against one pony alone is really difficult since Princess Luna is under Nightmare Moon and Daybreaker’s command.
 
“Now, shall we start the fight or are we gonna continue wasting time just having a conversation with no end?” Daybreaker asked, preferring that she starts a battle immediately and get it over with. “It isn’t really appropriate when we just sit and talk so long before starting a battle.”
 
Princess Celestia was brave and confident getting her sister back, and Daybreaker and Nightmare Moon also look brave and confident, knowing they must destroy the pony who destroyed them both that one time. All four alicorns fly up into the air, preparing for battle, becoming a three-on-one showdown.
 
“Attack!” Daybreaker ordered her sister and Princess Luna, charging at Princess Celestia with a kick, although Princess Celestia blocked her attack with her front hooves.
 
Princess Celestia, while guarding Daybreaker’s attacks, didn’t realize that both Nightmare Moon and Princess Luna are behind her, but luckily enough, she used her magic to stop the incoming attack from the two ponies behind her.
 
“How funny that a pony like you could actually stop an attack from three ponies at the same time.” Daybreaker told Princess Celestia, feeling surprised that the latter could ever do such a thing. “Unfortunately, if you believe you can dodge my attacks and the attacks from the ponies behind you, you must be mistaken!”
 
Daybreaker levitated Princess Celestia’s front hooves considering them a distraction, allowing Nightmare Moon and Princess Luna to attack Princess Celestia from behind.
 
“How’s that, sister?” Princess Luna asked her sister, knowing how it feels when the younger sister ends up working with her evil counterpart and her older sister’s evil counterpart, this leaves Princess Celestia outclassed, knowing Princess Celestia doesn’t have an ally.
 
Princess Celestia said to herself, “I know this may not an easy task for me alone, but if I don’t win, then I won’t have my sister back ever again. I must fight back! I have no choice!”
 
Sensing Daybreaker and Nightmare Moon are charging at her for a double attack, Princess Celestia created herself a barrier for enough time as she could.
 
“What’s this?” Daybreaker questioned, as she somehow can’t get through the barrier.
 
“This barrier is more powerful from before, and I’m using it as much strength for it until it runs out.” Princess Celestia said grunting and promising herself that she is not letting the barrier surrounding her breaks.
 
“Really?” Nightmare Moon asked, knowing the barrier cannot save Princess Celestia any longer, and she has a trick up her sleeve that can destroy Princess Celestia’s barrier. “Princess Luna!” Nightmare Moon called out.
 
Princess Luna flew very fast, and her front right hoof went right through the barrier with a hard punch, destroying it, leaving Princess Celestia shocked.
 
“Oh no…” Princess Celestia said, looking completely worried what was happening next.
 
“Now’s the chance, Daybreaker!” Nightmare Moon told Daybreaker, planning on taking down Princess Celestia with a new special technique, Daybreaker-Nightmare Dance.
 
Daybreaker rushed at Princess Celestia, kicking her in chest, and Nightmare Moon pulled out several kicks and punches, and slaps her back towards Daybreaker, giving her more attacks with more kicks.
 
“Now, together!” Daybreaker and Nightmare Moon said at the each other, firing multiple magic beams at Princess Celestia, leaving her completely unable to fight any further.
 
“These two ponies have me in a condition where I might not have a chance for a victory…” Princess Celestia said, looking exhausted and almost passed out. “Still, I must stand my ground and watch out for my sister while fighting Daybreaker and Nightmare Moon. They have my sister working for them. How can I even fight back?”
 
“You can’t keep fighting, Celestia.” Daybreaker told Princess Celestia after all the attacks she, Nightmare Moon and Princess Luna have been giving her, may result in Princess Celestia losing the battle forcefully, even if she didn’t surrender.
 
Daybreaker and Nightmare Moon smirked at Princess Celestia, letting her know that she has no way she can defeat at the way she is in right now, which was not looking good at all.
 
“Shall I finish my sister with you?” Princess Luna asked Nightmare Moon and Daybreaker, also wanting to take part in destroying Princess Celestia forever.
 
“No need, we both can handle this ourselves.” Nightmare Moon replied, looking confident that she and Daybreaker can destroy Princess Celestia without the help from Princess Luna. “Once Princess Celestia is gone, we will be Canterlot’s new rulers, and all ponies and creature will praise for who we are.
 
With that said, Daybreaker and Nightamre Moon fired a magic blast, aiming at Princess Celestia. Princess Celestia once again put her front hooves up, covering her head again. When she opened up her eyes, however, she was surprised that Twilight Sparkle has arrived in time, saving her from defeat, much to Nightmare Moon and Daybreaker’s anger.
 
“Great, Twilight’s trying to ruin our plans!” Nightmare Moon said with frustration, refusing to allow Twilight Sparkle interfering with her plans once again.
 
“Twilight, how did you…?” Princess Celestia asked Twilight Sparkle, wondering how did she make it in the first place.
 
“I’ve heard what happened, and this is why I cannot allow two ponies who are evil destroy my teacher I have cared for from the very start.” Twilight Sparkle said, doing the best she could saving her teacher’s life.
 
Twilight Sparkle knows that she must finish the job, and so, she did. However, before she could do so, Daybreaker and Nightmare Moon escaped, although they let Twilight and her friends win the battle, but promise them they won’t next time they meet, thus Princess Celestia finally got her sister back.
 
“Luna, are you alright?” Twilight Sparkle asked Princess Luna, who was regaining her consciousness from the mind control Daybreaker and Nightmare Moon have done.
 
“Yes, I’m alright, Twilight.” Princess Luna said, and she apologized to her sister for leaving the castle at night which she accepted.
 
“There’s so many stuff we gotta explain back at the castle.” Princess Celestia told Princess Luna as they both fly off heading for Canterlot castle without Twilight Sparkle, leaving the latter alone in the sky.
 
Twilight Sparkle turned her head towards the audience and said, “Daybreaker and Nightmare Moon will be back, and I will be waiting.”
