Nuclear: The Radioactive Changeling

by TheRadioactiveChangeling

First published 24th of December, 2019

A Changeling has been to the past multiple times, and became radioactive. He also is over powered with guns and magic.

Nuclear is a changeling that has seen the end of the world multiple times. He has tried to solve it multiple times, but never got there. But this time, something different happened. He was sent to the wrong location. He was sent to ponyville, inside twilight's castle. Now he has to figure the entire thing out, now with both friends (distractions sometimes), guns, and radioactive magic, cause he's also buffed to the eyeballs and armed to the teeth.

Disaster for the 413th time

Death. That's all he saw from the cliff point. Fire and storms ravaging the entire country. Ponies, changelings, dragons, griffons, and all other creatures were just burning to death as he watched it all happen. He tried to solve it, he really did. He tried everything he could think of to beat it to the punch, but nothing doing. He had to keep trying to solve it. Maybe he missed something, or he needed to go somewhere. He grabbed his pack, and ran for the base.

Now the creatures had already gone insane and tried to kill him for meat, but after doing this 413 times, you know everything that happens. He was being chased with spears, axes, swords, and just knives, but again, it was easy to beat them if you know everything. He pulled out the explosive, bit the string, waited, and threw it at the right time too explode in mid-air, and the head of the pony chasing him landed right in his hands.

"I'm gonna try to fix this, just stay sane," He said to the head. He then sat it on the ground, and ran to canterlot.

Canterlot was probably the most dangerous place in the apocalypse as the ones in it had actual training. However, they didn't have guns, which He did have. I'll just say, It was a massacre on one side, although the other side did get a injured leg.

"Ah... great. Good thing I've gotten used to it," He said as he covered his chest with a wrapped bandage. He then went to the throne room, which he knew where it would be. He enter the throne room, which had the injured versions of the princesses, almost looking dead.

"Princesses...I'll try again, and I can do it this time," He said to the bodies. He then looked at the door behind the throne.

"GASTO ME KANYA! TO WAHE THE WAKE! MASTERMENTIUM O RAD! MIND, SOUL, SOUND, SIGHT, FEELING! OPEN!" He Chanted to the heavens. The secret area was then lifted from the wall and out revealed the the machine that had the ability to send anything to any time. He opened the door with the code, 12826, and then went to the date console, and imputed the date of the time he needed to go to. But before he could press the button, the ponies came back.

"YOU'LL NEVER ESCAPE US! WE'LL EAT YOU ALIVE!" One of them shouted.

"Gonna be pretty hard cause I'll just SHOOT YOU IN THE FACE!" He shouted back as he opened the window with his flintlock, and shot like crazy, but in the chaos, he didn't realize a bullet ricocheted inside the machine and smacked the date console. The date was now march 26, 2016. The ponies were now dead, with flesh and blood everywhere.

"Jeez. Maybe I should've just hit the button to operate the machine. Well, at least I'm somewhat safe. Now, let's get this thing running," He said as he smacked the button without looking at the date console. He then held onto the safety rail as the thing goes from zero to 60 in 2 seconds. Blasting through time and space, he realized he accidently bumped into the place monitor and the machine would now appear in a random location in equestria.

"Ahh...Just great..."

Author's Notes:

March 26, 2016 is the time season 6 of mlp came out. He was trying to go to season 9. Now he has to go through Season 6 to season 9, or maybe use the machine again

see ya.

Castle

"OK. Library, library. Where did they put the library? [sigh] This Castle looked a lot smaller from the outside," Starlight was wandering the castle, opening doors, only to see a certain purple dragon shaving.

"Morning, Starlight!" Spike said, not embarrassed

"Whoops! Sorry, Spike! I guess I'm still trying to find my way around. You don't happen to know where the library is, do you?" She asked him, while shielding her eyes.

"Next door on the left," Spike pointed to the door next to him.

"Oh. Thanks," She said, with a hint of sarcasm.

"Acceptance, mm-hmm. Altruism, definitely. Starlight! Good morning! Come in!" Twilight said to her pupil.

"Sorry I'm late. I got a little turned around. I still can't believe you're letting me stay here. As your pupil. After everything I did," She said, slightly embarrassed.

"Well, I'm not one to dwell on the past and neither should you. The castle is your home now and as far as being my pupil goes I was just trying to figure out what your first friendship lesson should be!" She continued to her pupil.

"Oh. Well, it looks like you're really narrowing it down," Starlight said to her mentor.

"Oh, these are just the As," Twilight said to her student, while pointing elsewhere, "After this, I move on to the Bs!" which the elsewhere was a giant pile of papers, Which made starlight concerned. But then something unexpected happened.

"What in celestia's name is that sound?" Starlight asked as a tardis-esque sound appeared from nowhere, as a circular machine appeared. The sound stopped as the machine stopped spinning and appeared fully. The door on the machine opened as a certain changeling plopped out with a bunch of green gas also poured out into the roof. The ponies looked at the machine and changeling in disbelief, but the changeling looked at them.

"Oh...just great. I'm either in a castle home to an alicorn, or I'm high again,"

Author's Notes:

Surprise! He actually is kinda high.

Couldn't come up with a good chapter name

"Spike! Keep writing those letters to my friends and the princesses!" Twilight said as she kept the barrier spell working, only to find the rest of the mane 6 already in the doorway.

"How'd you guys find your way here so fast!?" Starlight complained.

"It's not really that hard. There's a map station," Rainbow said, only making starlight steamed.

"That's not important now, as there's a changeling right there and we need to do somethin about it!" Applejack said, stopping the rest of them from talking.

"Umm, girls..." Fluttershy whispered.

"Not now fluttershy, we need to get this guy out," Rainbow said.

"But...he's awake," Fluttershy said a bit quieter this time, only making them swing to the machine, only to see the changeling trying to fix it.

"hmm...maybe put this here? Nope, dosen't fi- oh, hey ponies. What's up? If you don't mind, I'm kinda in the middle of something, so uhh, can you get out for a sec? Thanks for those that did in advance," Nuclear said to all 8 of them, only spike and fluttershy leaving the room.

"Umm... Mr. changeling? Can yo-" Twilight was interrupted.

"Nuclear. My name's Nuclear, and I said can you get out for a bit please? This thing is actually, like, really important. So please, leave for a sec?" Nuclear asked, making them realize they have to discuss it outside.

"Ok, so what is with that guy? He kinda kicked us out of your castle twilight. And What the heck was that machine?" Rainbow asked.

"Do you know what that there contraption is twilight? You gotta have some idea," Applejack said.

"I wish, but that seemed way too technologically advanced, even for me," Twilight said, before the entire wall of the castle came crashing down as the machine blasted outwards, with the changeling shouting from the wall.

"Ok, I figured out what I need to fix the machine. A new machine."

Author's Notes:

Yeah, Yeah, but this chapter's all over the place and I couldn't figure out a good name.

Questions

"Ok, so we all go to him and ask 1 question, right?" Twilight asked her friends.

"YES! We all heard you the first 4 times! Let's just get it over with!" Rainbow complained.

"I hope so. You ponies have been yelling and asking each other for about 2 minutes now. I just need to find a way to speed up time and get a new machine," Nuclear yelled to them, which made them all realize to get on with it.

Enter: APPLEJACK

"So, uh, mr. changeling?" Applejack asked nuclear.

"NUCLEAR! I Told my name to you guys 6 times!" Nuclear yelled, making her jump back a bit.

"Ok. 'Nuclear' what are you doing here?" Applejack said, using up her question.

"Well, I don't know if you'd understand it, but I'm from the future where the world was destroyed by something that I'm trying to solve, and this machine, which I think is now broke, is a time machine I can use to travel anywhere, and somepony stupid smacked the control panel and now I'm stuck here until either I find something to fix this, or just wait until the world is broken again. Although I doubt that you ponies would want me to choose the latter," He explained. Applejack was now confused but also understanding in a mixed way.

"Okay... I'll go tell the others that," Applejack said, leaving nuclear to his devices for a few seconds.

Enter: RARITY

Rarity was somewhat scared and intrigued as she walked to nuclear, who was now actually looking at the machine from the outside, looking for mistakes on the outside.

"Umm... Mr. Nuclear? Was that it darling?" Rarity asked Nuclear, who nodded silently as he looked into the power converter.

"Yep, that's my name, and I believe I'm don't know you well enough to have you call me darling," He joked, making her sputter.

"Ah-uhh. No that's...what?" She spattered.

"I'm joking. I've been to Manehattan and met people like you," He said with a grin.

"Whatever, what are you?" Rarity asked, making nuclear realize that some ponies are stupid.

"I'm a changeling. Duh. You must know us," He deadpanned.

"Well, yes, but we've never seen a 'changeling' like you before," Rarity answered, making him somewhat frightened.

"Well...ok, rarity. I'm not telling anybody that, no matter what, unless someone's life depends on it. Got it?" he explained, then rarity walked away from him.

Enter: PINKIE PIE

The Bubble gum Mare hopped to the glowy changeling currently flying up onto the top of the machine.

"Hello Mr. Nuclear! Whatcha doin?" Pinkie pie asked.

"Hi. Right now just Looking around on this thing," He replied.

"Ok! Speaking of which, what is that thing?" She asked.

"A time machine," He answered.

"Ok!" She said as she bounced away.

Enter: FLUTTERSHY

Fluttershy looked around at her friends, knowing she was next. She crawled slowly to the changeling, looking at him intensely, not taking an eye off him, making sure he isn't doing anything bad.

"umm, mr nuclear?" Fluttershy asked.

"Yeah?" He asked, sliding down the pole on the side, which made a screeching noise that made fluttershy uncomfortable.

"umm...what is the green glow around you?" She asked quietly.

"That's called radiation. Don't stand in it," He answered seriously, making fluttershy have a hasty retreat.

Enter: RAINBOW DASH

"Ok, this guy isn't getting by my question," She said to herself.

"So Nuclear. Are you just a scout from a changeling hive?" Rainbow asked him with a tense tone.

"Nope. Just a random radioactive changeling here to save the world. Nothin bad here unless you try to hug me," Nuclear said as he completely deflected the question and made her fall to the back.

Enter: TWILIGHT SPARKLE

She walked to the changeling, now lying down in defeat as he couldn't figure out another way to fix this thing.

"So nuclear, was it?" She asked.

"Yep. Nuclear. That's me," He responded.

"Well...What's the future like?" Twilight asked a question that he knew was coming, but didn't want to answer.

"Oh boy. Well Twilight, Sit down here... Now, Are you brave?" He asked, where he received a slow nod.

"Well, You're wrong," He responded, making her head tilt, "Anypony that said they are brave, glorious, a warrior, or even
a god will tremble to their knees when they see what the world came too. Death around every corner, either from scavengers finding meat and food, ghouls killing for no reason, death claws hunting anything, raiders taking homes from others, or super mutants racking up the deaths every second. I couldn't describe the FIRST time I came through that hell of... well, hell. Not only that, but all ponies and creatures are stuffed into either suits and armor killing said creatures to clean the world, or just living in underground homes and stuffing their caps under mattresses. The World is a new home for tartarus, and it's even worse."

She was now terrorized from what he had told her, "But why didn't anyone stop whatever made this happen,"

"That's the thing. Nobody knows what made it happen, and that's what I'm trying to figure out," Nuclear said determined.

Enter: STARLIGHT GLIMMER

"So, twilight told me what the world came too," Starlight told him, "And I gotta say, I'm not really surprised," which made him somewhat sit up.

"Why would any pony not be surprised?" Nuclear asked.

"Well, I've also seen multiple horrible worlds, but I did fix it, although I didn't see yours. However, I know you can find it, with or without our help," Starlight told him.

"Hey, Aren't you supposed to ask me something?" He asked

"I gave my question to spike so he has 2. Welp, It's his turn. bye," She said.

Enter: SPIKE

"OK! WHAT IS THAT THING!" Spike yelled at the thing strapped to Nuclear Belt.

"Oh, my Pistol? It's a gun. Think of it like a Fast moving projectile made of strong metal that can pierce through a lot of things," He answered.

"Can I see it work?" Spike asked.

Nuclear looked to the group and then said, "Ok, but let's go somewhere else," He said as he lead Spike around the back of the castle.

"Where are they going?" Rarity pointed out the changeling and dragon going behind the castle, which was then followed by an ear piercing sound of a soon to be realized Glock-47 C.

"WHAT. WAS. THAT?" Rainbow dash yelled, worried that spike might be hurt as she raced around the castle, only to see nuclear holding out the pistol, pointing to a now hole in the ground, and spike watching in disbelief.

"That. was. SOMETHING AWESOME!" Spike yelled to the heavens, who then burped up a mail. "Twilight! Mail!" He yelled to his friend, who then opened it and read it.

Dear my Prized pupil, Twilight Sparkle,

I have recieved your emergency mail about a changeling and I have sent a 2 guards to watch over him and bring him here if he has proven to be hostile.

If he has proven to be more powerful then realized, you must send an emergency mail and me and luna shall come to you and find him.

Sincerely, Princess Celestia

Author's Notes:

Yeah, pinkie pie's was short, but that was the joke, as you don't need to tell her much to convince her.

Yep! I believe stuff quickly!

So.. yeah. See ya.

Powers

"Okay so while the guards are coming, do you have any other cool things or powers?" Spike asked the Changeling, who looked at him and the ponies.

"Well, yes, although This probably isn't the best place for it. I'd need like a, flat, building less area so nothing happens," He explained.

"Already on it! Come with me Nuclear," Rainbow said, leading the changeling to a flat lonely area in the field with the the team.

"Ok...Ready guys?" He asked them, which got a nod from all except fluttershy, cause she was too scared.

"My first power, which isn't gonna destory anything, is called power replication. Basically if I touch one of you, I gain any spells or skills in your mind or body. Here allow me to demonstrate by having rainbow touch me," Nuclear explained, while getting rainbow to touch his arm, which made a brief orange flash.

"So... Rainbow. Wanna Race?" Nuclear Challenged the rainbow maned mare.

"Buck yeah! Let's Go!" Rainbow blasted off, only to see Nuclear flying right next to her, with a glowing rainbow trail right behind him, seen by everyone. They stopped at the same spot at the same time, leaving all of them dumbfounded.

"Wow. He wasn't lying. That is awesome!" Rainbow Exclaimed.

"Alright, and thanks. My Next power is called Power Absorption. This is a pretty common one. You use this spell and drain all the magic out of something that has magic in it. However, I also have Power Division, Which is the exact opposite where you take your magic and share it with either just one person or an entire group," He Explained.

"So If you wanted to, you could take all of our magic or just take yours and give it to us?" Twilight asked.

He looked at her and at himself, "...Yeah, pretty much."

"Anyway, Another power is Matter Manipulation. I can turn myself in any form of matter, solid, liquid, gas, plasma, anything you want," Nuclear said.

"Ooh! Ooh! Can you turn into a donut?" Pinkie asked.

"Only if you don't eat me!" Nuclear said, which made pinkie nod, and he turned into a donut, with green frosting.

"Coooooool!" She Said, and he restored himself back into his default form.

"Suree... Anyway, another thing is the most chaotic, dimensicall. It basically can create portals to alternate dimesions and realities, and yes I can go to discord's world, and no I'm not doing it now. The last Time I did that I got stuck in a underground bug kingdom in a so called 'City of Tears' so no, I'm not entirely re-ready" He explained.

"Wait, if you can just leave this place, why do you even bother with this place and saving it?" Rainbow asked.

"Now, that's a good question, and I have 2 answers for that. 1: I like this place. It's calm whenever the apocalypse is happening. 2: is that, well... eh nevermind, just 1," He answered.

"Also, Nuclear darling, How long have you been wearing that?" Rarity asked, pointing a hoof at his clothes and gear.

"Oh, this stuff? Just about 40 decades," He said, making them all gasp.

"But... How do you look so young?" Twilight asked.

"Oh. Another power, Time exploit. I can control any object with time, except for time itself, which is why I need the time machine," Nuclear explained.

"But wouldn't you forget stuff when you manipulate time like that, Or do you have another power that counteracts that?" Twilight asked.

"Not so much a power, but an object called 'steel mind' I can't forget anything. Sometimes that's a real blessing. Othertimes I want to shoot myself cause I have it. It's complicated, but I'll come up eventually and I'll explain it then," He said, which they all seemed content with.

"So, any other Unsafe powers?" Spike asked.

"A Lot, but I only have 1 that's worth mentioning," Nuclear responded, making them ask "What is it?"

"I never said Worth mentioning Now. As I said before for the time travelling stuff, I'll explain another time. In the meantime, It looks like the princesses think I'm attacking you," Nuclear said making them look behind them too see the 2 princesses flying towards the flatland.

Author's Notes:

OOH BOY!!! FIGHT COMING ON!
Jeez calm down.
nah I'm good.
Oh great...
Anyway, see you later guys!

Royalty and stories

"Celestia? I thought you said You were sending guards! Not yourselves!" Twilight said, pulling the scroll from earlier, only resulting in a hoof lowering the scroll from her.

"I did. But when they reported that nobody was in the castle, or outside, We got worried and decided to see around ourselves," Celestia explained, and she released the hound.

"WHAT HAS THEE GREEN CHANGELING DONE TO THOU!" Luna Blasted her canterlot voice.

"Ok, first, Slow your mello a little. Secondly, I haven't done anything. And Thirdly, why would you just a-" Nuclear was interrupted by Starlight, "Don't make it worse for yourself," She said.

"But I didn't do anything!" Nuclear yelled.

"SILENCE CHANGELING! YOU SHALL TORMENT THEM NO LONGER!" Luna Screamed.

"I NEVER TORMENTED THEM!" Nuclear yelled at her.

"Let's all calm down. Sister, let's listen to the changeling, and changeling, don't lie," Celestia said.

"Well, I don't know if you'd understand it, but I'm from the future where the world was destroyed by something that I'm trying to solve, and a machine, which is back at the tree castle and I know is now broke, is a time machine that I use to travel anywhere, and some pony stupid smacked the control panel in said destroyed world and now I'm stuck here until either I find something to fix this, or just wait until the world is broken again. Although I doubt that you ponies would want me to choose the latter," He explained.

All of them except for applejack, cause she heard the same thing earlier, were confused. "He's not lying every pony," Applejack proclaimed.

"Can you tell us more?" Celestia asked.

"Well from what I know the end of the world was caused by, I think 3 creatures. One was a...Horse...Man? It had a black horse legs and body, but also the body of a...Buff monkey? And it had 2 curved horns on it's head that it uses for magic," He explained.

"Tirek. Definitely tirek, Nobody else looks like that," Spike said, and everyone except for nuclear agreed.

"Another one was a Tall changeling with blue hair, a long crooked horn, a crown, and a few other features. I know who this is, and I think you know too," He said, where everyone else nodded and said," Queen Chrysalis,"

"The last one was a Tiny Pink alicorn with blue curls for hair, and a chess peace as her cutie mark. So If you know her, Lock her up. If you don't keep and eye out for her. That's all I really know about the ruined world," He said, with some confused looks on the ponies faces.

"...Should we go now?" Spike said.

Author's Notes:

HAHA! Got ya!
Why are you happy? If anything you disappointed them changing the subject.
Haha...Oh yeah. Don't be upset, but I Don't want any alicorn and changeling blood anywhere.
Seriously? Come on, I, you, and everyone else knows I'd only last like, 4 minutes.
meh, Don't sell yourself short.
Ah, come on! I wanted to watch that too! I got Popcorn and everything!
Your Sick Discord.
I've been called worse.
Anyway... See ya.
