Twilight Sparkle had been missing for three weeks. Okay, she wasn't kidnapped or anything but her friends were only able to see her during classes. Outside classes, she was heading straight to the school's workshop or her home and working with countless tools and computers. She was obviously building something, she wasn't telling anything to her friends about it. Hell, she wasn't even talking or texting to her friends at all and they were becoming extremely worried about her.
Finally, after three weeks of absence, she finally texted to her friends and told them to come to her house so that they could see what she had built. As they started heading there, they entered into a discussion about what their friend wants to show them.
"What do y'all think she's cooked up this time? A time machine?"
"I have no idea. But it's gotta be very big considering all the time she spent on building it."
"Maybe it's a food distributer for homeless animals around the city."
"Or maybe a website that decides what you should wear daily, depending on the weather or whatever's popular this season."
"Or a maybe a totally creepy-looking robot that looks like another creepy-looking robot from a universe full of superheroes created by an old gentlemen who always cameos in the movies of his creations!"
Everyone looked at her dumbfounded.
"What?"
"Yeah, I'm pretty sure that's not what we're going to see."
"Oh, yeah? Ten bucks says you're wrong, Rainbow."
"Ha! You're so on!"
They spat on their hands and shook them.
"Can we get goin' please? I don't wanna waste the whole day on this banter!"
"Easy, AJ! We're moving, okay? Jeez!"
They continued walking towards Twilight's house and reached it in a couple of minutes. Twilight opened the door at the first knock and let's just say, calling her appearance messy would be a total understatement. She was wearing a lab coat full of scorch marks, her hair was a disaster and she had a terrifying grin on her face.
"Thanks goodness you're all here! Come quick!"
She pulled them inside the house and pushed them towards her room, which was equally horrible looking. Machine parts, papers, clothes, and computers were scattered everywhere. The only orderly things around were an object covered with a white sheet and Spike lying on the unmade bed. He instantly jumped off the bed and began shaking his tail when he saw the girls.
"Hey, guys!"
Rarity immediately went to pet him.
"Well, hello there, Spikey poo! I've missed you so much! What have you been up to?"
"I'm alright. But I can't really say the same for Twilight. She hasn't eaten or slept at all for three days, and it's all because of that ro-"
Twilight quickly covered his mouth before giving the girls a nervous laugh.
"Sorry about that but I'd like to make this introduction myself."
Then, she went near the mysterious object.
"Ladies, behold the ultimate peace-keeper. ULTRON-5!"
As soon as she removed the sheet, all of her friends gasped in terror. The object was a robot with a body similar to that of a human and a head similar to that of an ant. It's eyes were glowing blue.
"AH! CREEPY ROBOT!"
Then, she realized something and an evil grin appeared on her face.
"So, that means..."
Rainbow gave her a 10-dollar bill while still staring at the robot and Pinkie took it a huge glee.
"Twilight, what in tarnation is that monstrosity?"
Sunset hit her in the shoulder for that.
"What? You've gotta admit it's a little intimidatin'."
Sunset rolled her eyes.
"First of all, Applejack, it's not meant to be scary. I had to come up with a design to make the antennas relevant, so I decided to model the head after an ant's head. 'What do these antennas do?' you may ask. Well, let me show you."
She turned towards ULTRON-5.
"Initiate the scan."
It's eyes glowed even brighter.
"Scan complete. Seven sources of Equestrian magic detected. One source located 30 inches to the north and the other six located 3 feet to the north. Danger level low on all sources. Standing down."
"Wait a minute. Are you saying this thing can find Equestrian magic?"
"And contain it if it becomes out of control. I've equipped this robot with every tool and non-lethal weapon imaginable from stun laser to bug spray. Whenever an incident involving rogue magic takes place around the city, it will simply fly there and get it under control so that we can remove it with our own magic."
"WHAT?! It can fly, too?!"
"Yep. With the jet boosters I installed on each foot, it can fly up to one hundred miles per hour. Pretty cool, huh?"
"Cool? No, it's not cool! IT'S AWESOME!"
"Well, you certainly know how to exceed expectations, darling. You spent all these weeks building this machine so that it makes our job of getting under magic under control less tiring. Even I can't be that generous."
"So, I take it you all like my new invention and wanna test it out?"
Everyone except Rarity and Rainbow thought about that really hard.
"Well, it sure looks useful but what if it finds a magical threat that it can't beat?"
"I'm glad you asked that, Sunset. You see, what makes Ultron so different from the other robots is that it's equipped with the first ever Artificial Intelligence program that allows it to learn from the situation and adapt to it. And thanks to its very own molecular re-arranger, its body is allowed to evolve even further."
"Okay, time out! I know where this is going. If sci-fi movies taught me anything, it's that when robots become smart, they immediately start a robocalypse."
"Not to worry, Rainbow. I carefully programmed Ultron to never harm any living being. Besides, I can always shut him down with a single voice command."
She turned towards Ultron.
"Initiate the shutdown sequence. Passcode, Orion."
"Shutdown code accepted."
It's eyes immediately faded to black.
"You see?"
"Okay, that IS pretty cool."
"So, does that mean you're okay with it staying online?"
Everyone thought about it again (except for Rarity and Rainbow, because this is their first time thinking about it) before nodding in unison.
" I guess it won't hurt anybody if we leave it on."
"Sunset's right and also, I might've been a little too harsh with the whole intimidatin' comment."
"I'm sorry too. I think I hurt the nearby ants' feelings when I got scared by Ultron's head."
"Aw, don't worry, Fluttershy. I'm sure they'll forgive you in time. Hey, how about we show them that we now like Ultron by throwing a new-friend-party?!"
Everyone cheered in unison.
"Great idea! You guys go ahead. I'm gonna turn Ultron back on and meet you downstairs."
She once again turned towards Ultron.
"Initiate the activation sequence. Passcode, Prime."
The eyes started to glow blue again.
"Activation code accepted. Would you like to restart the scan."
"Sure, go ahead."
The eyes glowed even brighter.
"Scan complete. One Equestrian magic source detected. Location, 1.5 miles to the northeast. Danger level, high."
"What? You mean something with rogue magic is wreacking havoc somewhere right now?"
"Affirmative. Permission to intercept."
"Permission granted."
It immediately fired up its jet boosters and flew through the open front door.
"Come on, guys! Ultron's heading northeast. This is the perfect chance to observe his combat abilities firsthand."
"Does that mean we're gonna follow it."
"Fluttershy, it just flew out the door at fifty something miles per hour towards the other side of town to intercept a rogue magic source. Of course, we're following it!"
"Uh, maybe it's not such a good idea. It may not like us getting in the way or the rogue magic source may turn out to be another demon or-"
"Come on! It's gonna be fun! Besides; we have to see that it can handle huge magical threats, with our own eyes, right?"
"Oh, I guess you're right."
"Then, what are we waiting for? LET'S GO AND WATCH OUR ROBOT BUDDY TEACH EQUESTRIAN MAGIC SOME MANNERS!"
Rarity quickly called the limo service and in a few minutes, they were on their way to see Ultron's first encounter with magic.
