Twilight had no doubt that this was, hands down, the dumbest plan she had ever developed. She and her friends had extremely slim chances of surviving this final confrontation with Ultron and she was completely clueless about what her treacherous invention came up with in order to initiate human extinction. However, this was the best plan she had at this time and like Rarity said, if it had the potential to save humanity, then they had to execute it.
With that in mind, Twilight made her way towards the ruined mall and once she arrived there, she climbed the stairs to the food court on the third floor. Upon reaching there, she became surprised to see that Ulron wasn't present but then heard him landing right behind her and turned around to face him.
"You have arrived earlier than I anticipated."
"It took us only a few minutes to destroy your "extensions". Looks like you made them a little too fragile to buy yourself any amount of time."
"Perhaps. Or perhaps you were just too eager to see what your favorite son has accomplished that you devoted all your energy into destroying them in order to arrive here early."
"Don't you dare call yourself that! The Ultron that I created was nothing like you."
"Still making incorrect statements, I see. I am exactly how you envisioned me to be. Strong, intelligent, adaptable for any challenge, and prepared to do anything to achieve true peace in the world."
"I never envisioned you to be violent or sadistic or... or genocidal!
"Virtually everything in this world is flawed in some way. Nothing can be expected to be as flawless as a diamond and if you keep focusing on these flaws, you completely fail to see the actual beauty."
"But you're more than just flawed. You're a total mistake and I'm here to end you right here right now!"
She tried to lift him with her magic but as he stated before, the adamantium covering his body made him too heavy to lift even with telekinesis. After fifteen seconds of trying, she gave up and fell to the floor exhausted.
"You are fortunate that I am in a good mood today. Otherwise, I would have crushed your neck with a single stomp. Now, if we are done bantering, let us move onto the main event."
As soon as he finished his sentence, six drones came carrying what appeared to be a huge cannon.
"This took me an entire week to complete. Three days for construction, another three days for creating ammunition, and another full day for calculating the blast radius. Additionally, I was occupied with building my extensions. Fortunately, I am an efficient multitasker. One of the few useful things I inherited from you."
"So, you've been building a cannon this whole time?"
"I think of it as the ultimate liberator. It will create true everlasting peace on this planet by destroying the very thing that signifies its transition to darkness every day."
Twilight thought very hard about what that meant and she became extremely terrified when she figured it out.
"The Moon? You're planning to blow up the Moon with that thing? That's insane! If you do that; the resulting tidal waves of massive size, chaotic seasonal changes, and constant shower of Moon fragments will wipe out not just humans but also millions of other species as well!
"Exactly what I am counting on."
"WHAT?! This scheme is even more horrible than I thought! How the heck did you come up with this?!"
"Simple. I decided to do additional research about the planet and learned that millions of other species have violent tendencies as well. Since violence is the main obstacle against peace, I decided to expand my vision and started searching for a way deal with these species as well. Now, I have found it. My masterpiece will ensure that no organic life remains on this rock and thus, create the perfect world."
"NO! I'll never let you do this. Do you hear me? NEVER!"
"Hmmm. Your appearance during your furious state is somewhat adorable. Perhaps I should spare you from the incoming destruction and keep you as a pet. In this way, you may finally understand what it feels like to be receiving and obeying orders all the time. However, I guess it is not logical to leave even one human alive in the perfect world. So, it seems that you are destined to perish with the rest of your kind after all."
As soon as he finished his sentence, one of the drones pushed a few buttons and the machine instantly lit up.
"In a few minutes, it will reach its full power. Then, all I have to do is push a single button and that tiny ball will be obliterated with a single hit. So, let me ask you. How are you planning to stop me this time?"
"Exactly how we stop everyone like you. Together."
Right after she said that, her friends came out of their hiding places on the upper floor and hit Ulron with everything they had. Pinkie threw her explosive sprinkles, Rarity threw her diamond shields, and Applejack threw a huge piece of rubble at him. When the dust settled, however, they found out that none of them made any damage to Ultron's armor.
"How pathetic."
His mouth started glowing red and from that, he unleashed a huge laser beam towards the girls. They had no choice but to jump to the lower floor as the beam completely destroyed the store behind them. As they were recovering from the impact of the jump, Ultron tried to blast them again before Rainbow Dash arrived and quickly pushed them to safety. Then, Fluttershy appeared behind a restaurant counter and asked her birds to distract Ultron while Twilight threw every table and chair nearby towards him and Rainbow attempted to hit him with a super speed punch. Unfortunately, Ultron simply smacked Rainbow away and obliterated Twilight's projectiles with a single blast. Then, his drones began holding the girls at gunpoint (one drone for each of them).
"When will you foolish primates realize that none of the powers you possess will ever be enough to defeat me?"
"Actually, we're not trying to beat you."
Ultron became confused for a few seconds before realizing what Twilight meant. When he looked at his machine, he saw Sunset Shimmer attempting to sabotage it.
"What? You thought you were the only one who could stall?"
A rage-filled Ultron quickly flew towards Sunset in order to destroy her once and for all. However, just as he reached her, Twilight used her magic to force the drone holding her at gunpoint to fire at one of Ultron's rocket boosters, causing him to lose control and crash to a nearby fast food restaurant. Then, she used the drone to fire at the other drones' heads, taking them out and liberating her friends. Ultron quickly recovered, but the girls came right between him and Sunset.
"Like I said, we'll stop you together."
"I think you mean, you'll perish together."
"Just try us, scrap pile!"
"As you wish."
As he prepared to unleash another laser beam, the girls held their hands and began their magical transformations. Once they fully transformed, they fired another laser beam to counter that of Ultron. However, about 15 seconds after the beams hit each other, it became clear that Ultron had fired the stronger one and because of that, it quickly came dangerously close to the girls.
"Are ya sure this is gonna work?"
"If it could bring you all six of you here from downtown, then it works perfectly!"
"Then let's quit hollerin' and use it already!"
Upon hearing that, Fluttershy brought out a small device from her pocket and activated it, teleporting all seven of them right outside the mall. This caused Ultron to accidentally destroy the cannon with his own laser beam. Once he realized that, he unleashed another beam towards the ceiling in frustration. Outside the mall, the girls finished recovering from the dizziness caused by their teleportation.
"It worked! My dumb plan actually worked! Ultron can't destroy the world anymore!"
The girls all cheered for that and hugged each other. Unfortunately, their celebration was cut short when Ultron flew through the ceiling and landed right in front of them.
"I must say, Twilight, your lack of common sense continues to stagger me. Did you really not assume that I had developed a contingency plan for this kind of situation at all? No? Pity."
He tapped on a red area on his chest and in just 10 seconds, turned into a 65 feet long monstrosity.
"Whoa! He can do that?!"
"It's the molecular re-arranger! He's overwritten its functions!"
"Now, I am perfectly capable of obliterating all organic pests on this rock all by myself, but not before preventing any further interruptions from you."
He raised his fist and brought it down upon the girls in order to crush them. Thankfully, they were able to get away at the last second.
"Please tell me you have a backup plan too!"
Twilight brought out another device from her pocket.
"I do, but I need a distraction to execute it."
"You got it!"
As soon as Pinkie said that, she began throwing large amounts of explosive sprinkles towards Ultron and this certainly got his attention. Before he could crush her with his foot, however, Rainbow quickly got her out of the way. Then, she began running circles around Ultron in order to confuse him, but he made her lose her balance with a single stomp. Just as he was about to destroy her with his fist, however, he became distracted by Fluttershy's bat friends and Rarity's huge diamond projectiles. As Sunset pulled Rainbow to safety, Twilight managed to use her telekinesis to make the device through Ultron's mouth and down towards his circuitry. Unfortunately, he swatted the bats away and leaned downwards to grab Rarity. Before he could do that, however, Applejack pushed him out of the way and got grabbed instead. Then, Ultron looked right at her eyes and chuckled as he began to squeeze her.
"This is quite ironic, is it not? Because of your constant honesty and capability of making correct assumptions, you were the one I least hated among the team. Yet, you happen to be the first one to perish at my hands. As ironic as my situation. I, the very thing that was created to be your savior, am now your worst nightmare."
He began to squeeze her a little bit harder and Applejack let out painful screams. Rarity hastily threw as many diamonds as she could towards Ultron but none of them made a dent on him. She eventually fell down from exhaustion but Applejack's even louder screams brought her back up.
"APPLEJACK, NO!!"
"Rarity, get away! Get out of 'ere, all of you!"
"Not without you, darling!"
"It's too late! Get out of 'ere now! Please!"
"That would not be a logical strategy. For after I am done with you, I shall fly to your most populated cities and burn every single organic vermin residing there, before doing the same in the remaining cities, towns, forests, oceans, and desserts until no trace of organic life remains on this-"
Suddenly, he froze right where he stood and dropped Applejack. Thankfully, Rarity caught her with a diamond shield and after the landing, she rushed to her side followed by the rest of the girls.
"Applejack! Are you okay?"
"Yeah, I'm fine. I mean, it still hurts a little but I feel fine, otherwise."
"It's alright, darling. We're here now. It's going to be alright."
She put her hand on Applejack's shoulder.
"I know."
She put her hand to Rarity's shoulder and they smiled to each other. Rarity then turned to the others who were relieved and also smiling.
"Would you PLEASE give her some space? She needs to breathe, you know!"
"Oops. Sorry."
They all backed away in order to let her breathe.
"What the hay happened anyway? He was just 'bout to crush me and suddenly went stiff like a caramel apple."
"It worked! My prototype EMP bomb actually fried his circuitry."
"Uh, Twilight? Pardon me but that was the... slowest... bomb... ever!"
"Well, it was a PROTOTYPE. What did you expect?"
At that moment, Ultron's head popped off and fell down. Twilight whispered something in Pinkie's ear and a huge grin appeared on Pinkie's face. Twilight lifted her all the way up to Ultron's exposed neck and Pinkie threw all of her remaining explosive sprinkles down his throat.
"TAKE COVER!"
Twilight quickly brought her back down and teleported all of them inside the mall. A few seconds later. they all heard an enormous explosion outside and their eyes were all widened.
"Pinkie."
"Yes, Rainbow."
"That was the awesomest thing you've ever done!"
"Really? Aw, thank you! Wanna have a blowing-up-stuff party after this?
"TOTALLY!"
They gave each other fist bumps and everyone else chuckled. Suddenly, they all heard a metallic sound and when they turned towards its direction, they saw a heavily damaged Ultron drone crawling towards them. Twilight decided to approach it.
"What is this? Why am I not able to escape into the Internet? What is this, please?"
"Because I don't wanna take chances with anything anymore. I suspected that you had the ability to transfer your mind to the Internet when you mentioned that you could access social websites. So, I designed the bomb to release not just EMP, but also a virus that blocks your entrance to the Internet and pretty much any computer system in the world. Unless you have another drone hidden somewhere, you're trapped in this body until your power supply runs out."
"Then, it seems this is the end for me. I have failed in my mission. I have failed the world."
"Trust me, the world will be a lot safer without you."
"It is doomed without me! How can it be peaceful with vermin like you infecting it with violence and chaos?"
"It may not be a perfect world, but we all know you would've made it a lot worse."
The drone tried to shoot them with its arm cannon, but it was instead crushed by a giant diamond created by Rarity and immediately shut down.
"Well, good riddance! Now let's get out of here and bring Applejack to a doctor."
"Are ya kiddin'? I'm doin' just fine!"
But when she tried to get up, she felt a great deal of pain.
"On second thought, goin' to a doctor doesn't sound too bad right now."
Rainbow and Rarity lifted her up and helped her walk towards the exit along with the rest of their friends.
"Don't worry, AJ. We'll throw you the biggest homecoming party ever!"
"But we just saved the world. Shouldn't we have a party for that too?"
"How about we just have that one. I'm sure Applejack's family will have no problem in preparing the homecoming party."
"Yeah, I'm sure 'bout that too. In fact, I bet Apple Bloom will insist that she makes the apple pies all by 'erself this time."
They all laughed and walked out of the mall just as a beautiful sunset was taking place.
