Summary: Twilight Sparkle and her friends are shocked when they find out that Princess Celestia has grown to a destructive rampaging giant and she has been given all of Daybreaker and Nightmare Moon's powers. With only darkness controlling Princess Celestia and she has betrayed the six ponies again, Twilight and her friends must survive her wrath as she causes havoc all over Tokyo.

A month has passed following Daybreaker and Nightmare Moon's defeat in Dallas. Twilight Sparkle has been called a heroine for saving Dallas after saving the city from the giant alicorns. Now, Twilight and her five friends are enjoying a day in Tokyo.

"What? You defeated Daybreaker and Nightmare Moon on your own?!" Applejack asks with a shocked expression, feeling like Twilight Sparkle never told her about stopping the evil alicorns by herself. "How did you even do defeat them on your own anyway?"

"Well, I was able to use all the power and strength and combine it into a huge power that would make be able to hit the two alicorns while still normal-sized." Twilight Sparkle began explaining her reason to her friends on how she managed to defeat Nightmare Moon and her sister back in Dallas.

"And what happened after that?" Rarity asks, wanting more from Twilight on how the latter defeated the alicorn giants in Dallas.

Twilight Sparkle continues her reasoning, saying, "I used multiple magic beams to strike Daybreaker and Nightmare Moon in the chest, damaging them a lot and they shrunk shortly afterwards. I then gave them several kicks to finish them off and they were defeated, lying on the ground."

"So proud of you, Twilight...! We all are!" Rainbow Dash flies towards Twilight, hugging her for a mission that she has accomplished with anyone's help.

"Now with Daybreaker and Nightmare Moon defeated and gone for good, they won't be causing anymore mischief towards the humans, that's one thing I know for sure." Pinkie Pie said with a determined look that both Nightmare Moon and Daybreaker will never return to cause destruction ever again in the real world.

"If it wasn't for you, the world still would have been in danger from those two." Fluttershy tells Twilight.

On a beautiful sunny afternoon in Tokyo, Twilight and her friends stroll through the city sidewalks, chatting with each other feeling happy that Twilight was able to finish Daybreaker and her sister alone.

Later, at a city park, Twilight sits on a bench, reading a magazine about famous actresses, singers and models, whereas her friends are talking with each other nearby.

"Hey, Applejack, why don't we take some karate classes later?" Rarity suggests to Applejack that they both do karate elsewhere in Tokyo, hoping she can prove her karate skills. "You and I will be doing some serious training!"

"I'll accept that, I guess." Applejack agrees with Rarity to try some karate class sooner of today.

"Karate, huh? Let me be your teacher, please!" Rainbow Dash offers to be the teacher at the karate class Rarity and Applejack are hoping to attend later.

"Actually, there's gonna be a real teacher at the place, Rainbow." Applejack reminds Rainbow Dash that the building already has an instructor at the karate place, much to Rainbow's dismay. "But you can participate in taking karate class along with the both of us, if you want."

"Hmm, if you insist." Rainbow Dash replies as an agreement.

Twilight Sparkle, while still reading the magazine, says to herself through an imagination: "If there is one celebrity I would love to meet here in the city of Tokyo, it would be Miyuki Sawashiro!"

"Hey, what you're reading, Twilight?" Pinkie Pie walks up to her, wondering what Twilight's doing.

"Oh, hello, Pinkie Pie. I'm reading a magazine about famous celebrities from Japan, such as actresses, models, singers, and even manga artists." Twilight Sparkle responds with her head up, facing Pinkie with proper eye contact. "I even have thought about Miyuki Sawashiro, a popular actress from Tokyo! You all gotta see her one day!"

"What?! Miyuki Sawashiro?!" Pinkie, Applejack, Rarity, Rainbow and Fluttershy react in shock upon hearing what Twilight Sparkle has just said.

Fluttershy, confused over who Miyuki Sawashiro is, questions, "Who is Miyuki Sawashiro? I never even met her before."

"You all don't know who she is?" Twilight Sparkle looks at her friends with a raised eyebrow.

"Nope, not at all really. None of us have, actually." Applejack shakes her head with a "no", meaning she doesn't anything about the person Twilight mentioned.

Since Applejack, Rainbow Dash, Fluttershy, Pinkie Pie and Rarity are nowhere familiar with Miyuki Sawashiro, Twilight Sparkle begins to explain it for them, stating, "Miyuki Sawashiro was born in Nagano, Japan. She's an actress, as well as a voice narrator and voice actress. It is said that she been a fan of My Little Pony a long time ago and she has even voiced me, too."

"Whoa! I didn't think Miyuki Sawashiro was the voice of Twilight Sparkle! That's something we didn't thought of until Twilight told us now." Fluttershy tells Applejack, looking directly at her with a surprised expression.

"Look it up. This is basically true. I'm not making this up at all." Twilight gives advice on knowing more about Miyuki Sawashiro.

"Okay, enough of that, please. We've heard just about enough." Rainbow Dash wants Twilight Sparkle to drop the topic because she feels like Twilight has brought up enough info about the actress she mentioned.

Twilight decides to let it go anyway, already knowing her friends would be so annoyed hearing this for hours. She puts the magazine back on the stand and she orders her friends to follow behind her.

However, just as the six ponies start to walk, a voice from nearby came with a shout that had them left confused.

"HELP! A GIANT ALICORN IS ATTACKING THE CITY!" A man yelled as he panicked and ran for cover following an evil alicorn he claimed has attacked Tokyo recently. Twilight and her friends also see some other residents running and fleeing in terror as well.

"She's huge, her eyes are red!. She's gonna destroy us all! Somebody save us!" A woman cried out, holding her young daughter in her hands.

Rarity looks at Twilight, asking her, "Are they talking about Daybreaker?"

"No, I'm afraid that's not the case, Rarity. I believe the humans are talking about... Princess Celestia." Twilight Sparkle tells Rarity, realizing that Princess Celestia has become a rampaging giant and is unleashing her anger on the humans. Twilight's friends were shocked upon hearing this, leaving them in for the job to save Tokyo from Princess Celestia.

"Wait, you mean Princess Celestia has taken Daybreaker and Nightmare Moon's powers so she can get more stronger and then allow the darkness to take control over her again?" Applejack wonders if this is true.

"Yes, that appears to be the case..." Twilight Sparkle nods her head, letting her friends know that Celestia has been given all the power from Daybreaker and Nightmare Moon's powers upon defeat, which she has used to combine it with her own, resulting in Celestia becoming even more powerful.

"Oh, no! Not again..." Pinkie Pie reacted in shock, fearing that Princess Celestia might be a threat to the human world like she was a few times before. "How are we gonna be able to defeat her?!"

Twilight gives Pinkie Pie and the other ponies some heads up that it's not the end of the world just yet. They still have everything they can do to stop Princess Celestia from tearing Tokyo apart and try free the good side that began to disappear within her body upon letting the darkness take over her.

Now knowing what they must do, Twilight and her friends decide to get moving and save Tokyo.

"Fluttershy, Pinkie Pie, Rainbow Dash, Rarity, Applejack! We're gonna work together and protect the people and Tokyo, too!" Twilight Sparkle says loud and clear before they all march off to stop Princess Celestia from destroying Tokyo.

Elsewhere in the city, Princess Celestia has been causing massive destruction in her path, having destroyed and damaged several buildings that collapsed or caught on fire, killing hundreds and even thousands of citizens living in Tokyo. Watching the world burning through her eyes, she used her red magic to destroy more buildings for fun, in order to satisfy her wants.

Princess Celestia laughed in an evil manner, witnessing the people dying inside the buildings she targeted, watching other humans fleeing from her rampage, which was not enough to save them anyway.

The evil giant alicorn walks and stomps through Tokyo, knocking and destroying anything in her path. She crushes a couple vehicles underneath her hooves and fires her magic at full power, blasting away structures far from her. She glares down at the human with hatred, wanting to kill them all, hoping none of them can ever come back alive.

"Yes, yes... It's all coming together now! The darkness inside my heart stays forever!" Celestia says to herself, feeling so happy that the good side within her body is no longer in control and may never return for good. "Having taken all of Daybreaker and Nightmare Moon's powers and mix it into my own, I am truly unstoppable, which means nothing can hurt me, not even nuclear bombs, missiles, not one weapon can harm the most powerful and strongest alicorn in all of Equestria! I am immortal!"

"Leave us alone! Leave us alone, you tyrant!" One man begged the alicorn tyrant to spare him and the others while be backed away from her with fear.

"Oh, I wish I could let you all live, but sadly I'm not gonna allow it, not from what I've heard." Celestia rejected the tinies' offer in keeping them alive. "When I heard what happened to Daybreaker and Nightmare Moon back in Dallas, I went there to help them and they told me everything that happened. When they were almost about to die after being defeated by someone, they gave me all their powers and energy before they disappeared! Now I have enough to destroy this city in one blow! I can even wipe out the entire planet if I could, but I have interest in doing that, at least not yet..."

The man turns away from the evil alicorn giant, attempting to make his escape, but it would not work as it would give Princess Celestia the chance to fire her magic at him, turning him into nothing but dust. She laughs watching the man become nothing but ashes like she wanted him to be.

"No matter where you try to run and hide, it is useless against a goddess such as myself!" Celestia reminded the tinies that outsmarting her is not going to work with her.

The evil alicorn smiles at the tinies, preparing to unleash her magic once more as they try to get away from her in time. She fires her magic at full power, destroying any of the humans who have made any attempts to get away from her. Princess Celestia can only see nothing but destruction and terror inside herself, doing nothing aside from wiping out humans and destroy everything that's in her path. Nothing will keep the tinies safe from her rampage.

However, Twilight Sparkle and her friends stand before the dark alicorn, all of them ready to fight her with everything they have and working together as six.

"Alright, Celestia! This ends now!" Applejack told Princess Celestia, having had enough of the alicorn's cruel behavior towards the humans, which Applejack didn't approve it all. "You're gonna stop hurting these people and let them be!"

"You six ponies, hmm?" Princess Celestia recognizes the familiar six ponies from before. "The last time I fought Twilight was back in San Francisco, but the other five, I had dealt with them back in New York."

"We've heard what you've done and we're all gonna put a stop to it!" Rainbow Dash said, determined and eager to end Princess Celestia's rampage.

"You ponies don't realize, however, that Daybreaker and Nightmare Moon have given me all of their powers before they vanished forever!" Princess Celestia gave the six ponies a reminder about what happened in Dallas.

Twilight Sparkle and her friends are shocked upon learning what Princess Celestia has learned from the alicorns that Twilight defeated a while back in Dallas.

"Wait... you don't mean...?" Fluttershy asks nervously, wondering if this is actually true.

Princess Celestia replies before she continues her sentence, "Yes, this is true. And Princess Luna also has been given the powers from Daybreaker and Nightmare Moon, so she is just as evil as I am! I've defeated you all once before, and I'm gonna do the same thing again now! You all think you can defy the most powerful alicorn in the world?! You've got another thing coming for you!"

"I can't believe Daybreaker and Nightmare Moon have given Celestia and Luna all of their powers before they disappeared forever and lost all of their immortality." Applejack tells Rarity, who nods in an agreement with her. "Where's Princess Luna?!" She asks the red-eyed alicorn.

"Oh, don't worry. She's hiding at the base me and Celestia have kept even after Daybreaker and Nightmare Moon disappeared forever." Princess Celestia informs the six heroines that her younger sister is somewhere at the base where Daybreaker used to operate. "But I'm afraid she's not needed for this, because I'm the one who will take you down!"

"Guess that means we just gotta deal with Celestia, and we all must work together, everypony!" Twilight Sparkle warns her friends that the darkness inside Princess Celestia is growing stronger already before the fight can even begin.

Princess Celestia begins her attack by unleashing a powerful beam attack on Twilight and the gang. Luckily enough, Twilight Sparkle created a barrier before they could be hit, causing the beam to come straight back at Celestia, which damaged her front legs a little, pushing her back a little, though she managed still recover very quick, much to the shock of Twilight and her friends!

Knowing that Princess Celestia is a goddess and can live forever, only working together can defeat her regarding how big she is.

"She's not gonna back down without a fight! She sure is a threat to everyone and the whole planet itself!" Pinkie Pie was not happy that the alicorn goddess barely suffered any damage from her own attack. "Girls, I think it's time we start Plan A now! Rainbow Dash and Fluttershy will attack the alicorn and the rest of us will distract while those two attack Princess Celestia."

"Alright! Now let's go, Fluttershy!" Rainbow Dash orders Fluttershy to follow her lead as they prepare to attack the giant evil alicorn together.

"Right, Rainbow!" Fluttershy responds before the two Pegasi fly together.

Rainbow and Fluttershy both attack Giant Dark Princess Celestia at the same time, throwing multiple punches and kicks at her, but the massive alicorn levitated the two tiny winged-ponies away from her, putting them aside as she prefers to take aim at Twilight Sparkle.

"Hey, what gives?" Rainbow Dash looks confused on why Celestia had no interest in fighting her and Fluttershy just yet.

"I'll make sure to get my hooves on you this time! You'll pay for what you've done to Daybreaker and Nightmare Moon, Twilight!" Princess Celestia yelled before she unleashed a powerful magic beam at Twilight.

Celestia's attack came so fast that Twilight and her remaining friends have dodged the attack just in time. This resulted in Princess Celestia getting even more angry.

"If you don't stop dodging my attacks, I'll definitely wipe you all out at once!" Princess Celestia grew more frustrated with Twilight and her friends avoiding her attacks yet again. "YOU ARE SO DEAD ONCE I CRUSH YOU ALL LIKE THE WEAKLINGS YOU ARE!!!" She used her traditional Royal Canterlot voice, which echoed through the entire city, shattering windows all over the place.

"Hearing her with that deep voice, it could've shattered the whole planet in half!" Rarity said while covering her ears from Celestia's enormous, deep royal Canterlot voice.

"This, for sure, won't be good... We'll keep fighting all day, all night...!" Twilight Sparkle breathes hard while still trying the best she could staying in touch with every attack Princess Celestia will unleash on her and the others.
