(TMNP)Teenage Mutant Ninja Ponies

In the city of Canterlot it would look like it is a peaceful city, most of the time. Other times, they aren't so peaceful. Which is why the those who are destined to protect this city is training right now in the basement of a certain abandoned building.

Four female ninjas were just about to get ready for training by fighting each other. But these aren't just ordinary ninjas, for they are only half human, while the other half of them are ponies, so they have hands, instead of feet they have hooves, pony ears, and human bodies and faces. One had light orange skin, blonde hair and tail, had a red hair bow, wore a regular orange ninja suit with a symbol of three silhouetted apples and had a blue ninja mask , with two katana swords. Her name was Applejack. The second had cyan skin, rainbow colored hair and tail, wore a dark blue ninja suit with a symbol of a silhouetted cloud and lightning and had a red ninja mask, with two sai. Her name was Rainbow Dash. The third had lavender skin, sapphire blue hair and tail with violet and rose streaks, wore a violet ninja suit with a symbol of a silhouetted six-pointed star and had a regular purple ninja mask, with a bō which converts into a naginata. Her name was Twilight Sparkle. The fourth had light pink skin, regular pink, fluffy, hair and tail, wore a ninja suit that matched her hair color with a symbol of three silhouetted balloons and had an orange ninja mask, with two nunchuks which convert into kusarigama. Her name was Pinkie Pie.

For their training exercise they were going to face each other in battle. Rainbow Dash versus Twilight Sparkle and Applejack versus Pinkie Pie. Applejack and Pinkie Pie readied their weapons and began to fight.

"Yeah let's do this!" Pinkie Pie shouted as she ran and swung one of her nunchucks at Applejack's face. Applejack dodged it only for Pinkie Pie to continue swinging at her. "Come on, how do you expect to defeat me if you can't keep up?" Just then Applejack used the back of her fist on Pinkie's stomach.

"Like that?" Applejack asked looking back at Pinkie as she just defeated her.

"Good one, Applejack."

Rainbow Dash and Twilight were now going to fight. Twilight readied her staff but Rainbow Dash didn't raise her weapons at all. "Alright Twi lower your staff and you won't get hurt." Dash said hoping to convince Twilight.

Twilight however, wasn't convinced nor was she amused by what Rainbow said to her. "Yeah right!" Twilight said to her. "That's what you said the last time before you did hurt me."

Rainbow looked a bit shocked to hear Twilight say that. Usually she would fall for something, since this was Rainbow Dash she was talking too and she knew that Twilight wouldn't want to fight her. "Yeah well I would have kept my word."

Twilight twirled her staff in front of Rainbow for a little bit but then stopped. "Nice try." Twilight swung at her from the left and right, but Rainbow dodged them both. Twilight twirled her staff again and tried to strike at Rainbow's head only for her to grab the staff from Twilight's hands. Twilight was shocked by this and said, "I should have dropped the staff right?"

Rainbow Dash twirled Twilight's staff a bit and then she broke it by smashing it against her left knee. "Should've dropped the staff." Rainbow then used the two halves of the staff to hit Twilight multiple times.

Twilight couldn't take much more of and decided to quit. "I give, I give! Uncle!" She shouted making Rainbow stop. Which now made Pinkie Pie and Twilight lose the match.

Now Applejack and Rainbow Dash were the last to face each other. "Ready?" Applejack asked.

"Ready as I'll ever be."

Applejack brought out her two katana swords and Rainbow Dash brought out her two sai. They both ran toward each other and began the fight. One by one they both slashed their weapons, but not one of them are hitting the other. Applejack was then about to strike but Rainbow used one of her sai to redirect Applejack's arm and fling her across the room, allowing her to claim victory.

Yame!

All four of them turned and they saw their Sensei walk in the room to congratulate them on their training. Their Sensei wore a red kimoto with a symbol of a silhouetted sun and was holding a green crystallized staff. Just like her students she was also a half human half pony mutant with pony hooves, ears, and tail with human hands and a human body. She had Light fuchsiaish gray skin and her hair and tail had the shades of Light cerulean, Light turquoise, Very light cobalt blue, and Pale heliotrope.

All four of them got on their knees in a straight and waited for their Sensei's response. "You have all done well my students."

"And I won!" Rainbow Dash said.

"This is only a training exercise, Rainbow Dash this is not about winning or losing." Celestia addressed Rainbow Dash.

"Hai Sensei!" Rainbow Dash said to Celestia. "But I still won and they all lost." Celestia was not amused by that and went behind Rainbow Dash and pulled on her ear. Rainbow didn't expect that or how painful it was and quickly corrected herself. "But the important thing is, is that we all did our best. Go team!" Rainbow said getting Celestia to let go and chuckle.

Later on at night everyone sat at their dining table eating hay and daisies. "Anyone for seconds?" Pinkie asked to all of them.

"No thanks." Applejack said. "Think we've have about our fill on hay and daisies.

Pinkie smirked at them and said, "Well I hope you saved enough-" She then grabbed a muffin tin tray full of cupcakes. "-room for cupcakes." This got their attention in all the good ways.

They were practically drooling over how good they look, which seems fair since Pinkie was the one that made them. "Cupcakes!" Rainbow Dash said excitedly until she took a closer at them. "And they're made out of hay and daisies."

Twilight was a bit astounded by that. "How did you make cupcakes out of hay and daises?"

"I don't know." Pinkie said. "It just sort of happened when I was making them." Twilight didn't know what to say but decided to leave it at that.

Applejack was a bit confused about one thing though. "Uh Pinkie, what's the frosting made out of?"

Pinkie was a bit embarrassed by this and grabbed the cupcakes and pulled them away. "You don't want to know." Pinkie then thought she could help them forget about that by shouting, "HAPPY MUTATION DAY!" Thankfully it worked.

"HAPPY MUTATION DAY!" Everyone but Celestia shouted.

Celestia smiled at what they said. "Ah yes it has been 15 years since that first day hasn't it?" Celestia explained. "I still remember that day."

Pinkie cheered at what Celestia said. "Can you tell us the story?"

"Pinkie Pie you already know the story." Celestia said with a smile.

"Oh come oooonnn please tell it again!" Before Pinkie could continue whining Rainbow Dash placed her hand over Pinkie's mouth.

"Please Sensei!" Rainbow Dash pleaded. "It will get her to shut up if you tell the story."

Celestia rolled her eyes and gave in. "Alright then!" Rainbow Dash removed her hand from Pinkie's mouth and Pinkie calmed down and listened in.

15 years ago I was minding my own business walking through the streets of Canterlot until I came by a pet shop. When I looked inside I saw the precious and the most rarest sight ever in the middle of the shop. There I saw four baby ponies.

"That's us!" Pinkie Pie interrupted.

"That's right." Celestia said. "Don't interrupt!"

I'm not sure what it was about them but when I saw those ponies I didn't feel so lonely, so I adopted all four of them. You wouldn't believe how much money it cost. While I was making my way down the street I accidentally bumped into a strange looking man in a suit. However, once I looked back at that strange man I noticed that there was something off about him and I decided to follow him down the alley. When I looked back at him I saw the strange man again only this time he was with someone that looked exactly like him.

I was about to leave but that was until two more copies of that guy appeared behind and said, "You are trespassing in this place where you are trespassing and now you must be destroyed in this place where you are trespassing." Just then I noticed that all four of them surrounded me.

In an act of self defense I put the ponies behind me and attacked them. Little did I know that they were skilled in fighting, but I wouldn't allow them put harm on the ponies and myself. That was until I knocked one of them back and he dropped a canister of a suspicious looking goo and spilled all over me and the ponies. The four of them ran off while the goo did something to me and the ponies.

The ponies then grew taller and formed human bodies, faces, and hands, while the same thing happened to me.

Celestia held up the same canister from her story and the same one that changed all of them into the half pony half human mutants. "And that is how we became the most unlikeliest of families."

Pinkie grabbed the canister and hugged it. "Dad." She said with a bright smile.

With the story out of the way Applejack thought now was the time to ask her the one thing that has been on her mind all day. "So Sensei?" Celestia then looked at Applejack. "Now that we're 15 and since we're pretty adroit fighters would it be alright if we...I don't know...go out in the city?" Her asking that made all four of them look at Celestia hoping that she would answer them.

"Yes-" All four of them cheered at that. "and no." All four of them stooped and looked at her wondering why she said that. "It is best for you all to see the city and gain new experiences but you lack enough wisdom and therefore could lead to danger."

'So that's a no then?"

"Yes...and no."

"Huh!" They all said in unison

"It's true you don't have the wisdom but wisdom comes from experience and experience comes from making mistakes."

Twilight still didn't fully understand what Celestia was getting at. "So we can go then?"

"No!"

"And yes?"

"No!"

Applejack stood up and looked at Celestia. "Come on Sensei, how do you expect us to gain experience if we're stuck here forever?"

That got Celestia thinking. She knew that Applejack was right about that, but still wasn't sure. However, when she looked back at the four of them they were all on their knees and begged with pleading eyes. Celestia was then convinced. "You may go!" After that they all cheered again.

Later on without Twilight and Pinkie, Applejack and Rainbow Dash were in the living room. Rainbow Dash was reading a book from her favorite book series 'Daring Do' while Applejack was watching her favorite show, 'Space Heroes', mimicking all the characters poses and dialog exactly.

Rainbow Dash looked up and Applejack and wasn't amused. "You know that show isn't even that good."

"Says you." Applejack said not looking away from the TV. "One day I want to be just like him."

"If by that you mean being a dork than you're well on your way." Rainbow Dash said looking back at her book and making Applejack's eyes roll.

Before anything else went on Twilight and Pinkie came in. "Come on girls!" Pinkie said getting their attention. "Let's get going!"

They all grabbed their signature weapons and some ninja stars. They were all ready to head outside and into the city of Canterlot, however, they had to speak to Celestia first. They stood in a straight line and awaited her words. "Remember you all must stick together and must maintain awareness."

"Hai Sensei!" They all said in unison.

"Stay in the shadows!"

"Hai Sensei!"

"Don't talk to strangers!"

"Hai Sensei!" They started to get a bit annoyed.

"Everyone is a stranger!"

"Hai Sensei!" They all headed to the exit.

"Make sure you go before you leave, the restrooms up their a filthy, especially those from a gas station."

"SENSEI!"

Celestia looked down and sighed as they were all headed out. "Good luck my daughters."

Before they went outside Applejack looked around to see if anyone was there, thankfully no one was there. Once the coast was clear they all headed out and now they were outside for the very first time in 15 years. The sight before them was amazing, just like the stuff they see on the news and regular TV shows. Buildings, lights, dark sky, stars, a whole bunch off stuff you see at night.

"This place is beautiful!" Pinkie said as they were walking out of the alley.

They looked all over the place. There were houses, stores, there was a sweet shop called Sugarcube Corner, about a lot of things. Twilight was amazed by the amount of technology they have in this city, much to Rainbow Dash's annoyance. Pinkie Pie was too excited to see everything that just kept staring at the lights of a building that belonged to what the store said, 'Zecora'.

During all of this however, when they were walking through the street they were encountered by a guy in a motor scooter. Rainbow Dash only helped him get scared and ride away. They all had to hide and hope that, that guy doesn't remember this anytime soon. Pinkie however, looked at a box that he dropped and decided to take it.

On the rooftops they were looking at the box that the guy they saw drop. Pinkie looked at the words on it and read out load, "Pizza!" This only made their curiosity grow.

"Careful girl!" Applejack warned all three of them. "We don't know what this is." Rainbow Dash then used one of her sai to open the box and then they saw a circular form of dough stopped with tomato sauce, cheese, and pepperoni.

Twilight looked closely at it and only came to this conclusion. "It looks like food."

"It's not like any food I've seen." Rainbow Dash said.

Pinkie Pie reached for a slice. "I'll try it." She said as she grabbed one. She held it out to her face, slowly opened her mouth, and took a small bite. Little did she know was that one small bite was enough to blow her mind. Now knowing how good this is she stuffed the rest of it in her mouth, chewed it all up, and smiled as she swallowed the whole thing, burping in the process. She looked at the others and didn't want them to have the rest of it. "Uh...yuck, that was disgusting." She lied. "None of you would want any of this so I'll just take what's left." Too bad her plan didn't work.

All of them each grabbed at least two slices of pizza and chowed down on it, enjoying the delicious taste of the hot and gooey, cheesy goodness. "I never thought I would taste anything better than hay and daisies, but this is amazing!" Rainbow Dash said as she ate her last slice.

Now that they were all done Applejack spoke up. "Alright girls it's getting late we better head back."

Before they left Twilight looked off to the side on the street and saw something that amazed her. "Wait girls look!" They all looked at what she was looking, but actually it was who she was looking. Walking down the street was a woman about in her 40's with light yellow skin, sapphire hair, with a green shirt with a dark blue skirt that reached to her knees was walking. But amazed Twilight was who she was walking with. She saw a boy about her age with the same colored skin and hair as the woman he was walking with. He wears a white shirt with a decal of a lightning bolt in front of a blue shield, a black jacket with red and white stripes over the shirt, and blue jeans. Twilight was star struck and her heart was beating rapidly at the sight of the boy. "He's the most handsome guy I've ever seen."

"Isn't he the only guy you've ever seen?" Rainbow Dash asked Twilight breaking her out of her trance.

Twilight looked away from them and blushed. "My point still stands."

"Wait girls!" Applejack said silencing them. "Look at that." She pointed at a van that was headed in the direction of the two humans.

The van stopped right in front of the two and out came a teenage girl with light turquoise skin and amber colored hair with a golden streak, she was wearing slacks and a gold shirt with a decal of a lightning bolt with three stars on it. Three more came out of the van and these were what shocked all four of them the most. These guys were the same guys that their Sensei described in her story. What shocked them most was that they had weird looking guns and pointed them at the woman and boy.

The both of them were scared by this. "What going on here?" The woman said. "What is the meaning of this?" Before anything else could be said two of the strange men grabbed them both.

On the rooftops they were shocked by what they saw. "We've gotta save them." Twilight said.

"Hold on!" Applejack said to them. "Celestia's instructions were very clear. We're supposed to stay away from people...and bathrooms." However, what Applejack said wasn't enough to stop them from trying to stop those guys. After angrily sighing she decided to join them.

The woman and boy were struggling to get out of their grasp to no avail. "Let us go!" The boy said while struggling. They threw the woman in the van and was about to the throw the boy in, but the ponies then came in their way.

Their main targets were the strange identical men in suits. However, as they were attacking them they seem to be getting in each others way. When Rainbow Dash was about to attack one Twilight used her staff to launch herself at him only to lose control and flung herself towards Rainbow Dash knocking them both back. Applejack was doing her best to get them but seems a bit out of focus to make a single hit while trying to avoid the blasts from the weird looking guns they have. The boy was watching the entire thing and when Twilight came by to help him he screamed at the sight of the pony mutant which made her scream. However, she tried her best to keep calm only to be hit by Pinkie's nunchucks which then got them both knocked down by one of them. He then grabs the boy and they drive off with both humans.

Twilight watches as the were taken away. "We've gotta save them." Twilight said as she was headed in the vans direction with Rainbow Dash and Applejack following her.

Pinkie was about to follow them when one the strange men confronted her. "Just you and me tough guy." She then swings her nunchucks at the strange man only for each strike to be useless. "You think you're tough, huh!? You think you're tough enough to stand up to my HOT NUNCHUCK FURY?!" She shouted as she was about to swing at his head only for him to grab her nunchucks out of her hand. "Well then...AHAHA!"

Not knowing what else to do, she thought it would be best to run. While running the strange man was following close behind her. She went into an alley where she was now cornered by the strange man again. She then swings blindly at the man with her nunchucks that she made the blade come out and form a kusarigama. "TAKE THIS!?" She then managed to hit him.

When she looked she was shocked by what she just did to the strange man. Only the thing was that it wasn't a man at all, it was robot with a human disguise. Before Pinkie could react the robot powered down and when that happened a brain like creature came out of it's chest and attacked Pinkie. It latched itself on Pinkie's face making her scream and try to take it off. After a few attempts she finally managed to remove the creature and then it left.

Pinkie tried to run after it but then she nearly bumped into Twilight, Rainbow, and Applejack. Thankfully they heard her scream. "Girls you're not going to believe this." Pinkie began to explain. "That man we just saw he..h-he...had a BRAIN!"

She was right, they didn't believe her. "We all have brains Pinkie." Applejack said.

"Not all of us." Twilight said with a hint of sarcasm.

"In our chests?!"

"No, Pinkie. Not in our chests."

Pinkie wasn't liking that they weren't even going to listen to her. "YOU'RE NOT LISTENING TO ME!" Just then Applejack slapped Pinkie in the face. "Did you just slap me?"

"I was calming you down."

"WHY WOULD THAT CALM ME DOWN?!" Pinkie looked back at the alley and hoped that the robot body was still there. "Come on I'll show you." They all headed back to the alley where Pinkie was but didn't see a robot anywhere. It was completely deserted as if nothing was there at all. Seeing that there was nothing there the three of them left. "I'm telling you the truth!" Pinkie said as she was following them.

They went back home in shame as they await their punishment by their Sensei. They were all on their knees in a straight line while Celestia was pacing back and forth. "This is by far the most foolish thing all four of you have done." She scolded them. "Not only did you all fail to work together as a team but you also managed to let them get away with two innocent bystanders."

Applejack couldn't take much of this. "Sensei we would have stopped them and saved those humans if someone listened to me in the first place." She said looking at Rainbow Dash.

"Well I would have had those guy taken care of if someone didn't get in my way." Rainbow said looking at Twilight.

"I would have saved those two humans if someone didn't me in the head with her nunchucks." Twilight said looking at Pinkie Pie.

"Well none of this would have happened if-" She looked beside her only to see nobody else there. "None of this would have happened if someone didn't trust us to go out there in the first place." After she said she covered her mouth and the others gasped.

"No Pinkie Pie, you are right." Celestia said making all of them confused. "I shouldn't have let you gone out there so early. All four of you were inexperienced and I should have trusted my instincts." She turns away from them and starts to head to her chambers. "We shall continue training and maybe in a year we will try again."

Twilight didn't like where Celestia was going with this one bit and spoke up. "Are you kidding me Sensei!" Saying that made Celestia stop and stare back at her. "Those innocent people don't have a year, we need to save them now." Celestia was about to say something when Twilight spoke up again. "You weren't there master you didn't see what we saw. The look on that boy's face, he didn't know what to do, he was counting on me-" Twilight then looked at the others and saw that they were staring at her. "-counting on us to same both of them. Please master, we can't let them be trapped any longer."

Celestia considered Twilight words and look at a picture she had back when she was a human. In the picture she was there with her husband, Sombra, and their daughter. As she was looking at this picture a whole bunch of memories came flooding in. Memories of her past life and how it all ended. Knowing that Twilight was right about this she had no other choice. "Alright! You must go back and save those two from these strangers."

"And from the robots with creepy brain things in their chests." Pinkie Pie said.

"Let it go already." Rainbow Dash said.

Applejack looked at the other and then back at Celestia. "With all due respect master we were not fully focused out there."

"Yes indeed!" Celestia said. "In order to save them all four of must work together as a unit. And in order for that one of you must lead the others."

Applejack was the first to ask. "Can I be the leader?"

"Why should you be the leader?" Rainbow Dash asked. "I kicked all of your butts. I should be the leader!"

"Now hold on." Twilight said. "I'm smarter than all of you, so the leader should be me."

"No I should be the leader." Pinkie said making all of them stare at her. "I don't have a reason I just think that it should be me."

Celestia walked toward her chamber doors and opened them. "The choice of leader is a very important decision. I will meditate on this." She closed the doors and just a few seconds later she opened them again. "It's Applejack." She then closed the door again.

Applejack looked over at Rainbow Dash and saw that she was a bit frustrated by this. "Jealous?" Applejack asked Rainbow making her angrily sigh.

Back in Canterlot on the rooftops the ponies were observing a building that had the same logo as the one on the van that captured those two people. "You sure this is the place?" Twilight asked Applejack.

"Of course." Applejack said pointing at the sign. "That sign is the same one as the one on the van that took those two away. Now we just need to wait for someone to come out."

Pinkie looked at the building. "Well I don't see anyone." Saying that made Applejack sigh.

"We see that there's no one there Pinkie!" Applejack said looking at Pinkie with an annoyed expression. "We just need to be patient." She said making them all calm down and wait. However, the wait was a bit longer than they thought so they decided to waste some time practicing with their weapons and playing games that quickly get boring.

"I'm thinking of something...blue!" Pinkie began a game that she was playing with Twilight for about 30 minutes. "Colorful. Bluuuee."

Twilight rolled her eyes and sighed. "Is it Rainbow Dash again?" She asked with a bored expression.

"Man, you're good at this!" Pinkie cheered.

About the second hour came by and still no one came out of the building or went in. Rainbow Dash has had about enough of this. "Give it up already!" She said to Applejack. "The chick is not gonna show."

Applejack however, didn't care about the waiting. "We have to be patient."

"No! You have to come up with a better plan, because us sitting here with our thumbs up our noses-"

"I don't think they fit..." Pinkie interrupted trying to see if her thumb were to fit in her nose.

"-Is pointless!" Rainbow Dash continued still looking at Applejack.

Applejack looked back at the building and saw that a van was pulling up. Not just any van, but the same van they saw earlier. Seeing this made Applejack smirk and turn to Rainbow Dash saying, "Are you sure about that Dash?"

"She just showed up, didn't she?" Applejack nodded making Rainbow Dash look at the van that just came. "I should have complained two hours ago." She mutters.

The same girl that was with those strange men from earlier just climbed out of the van and grabbed some crates. Applejack stood up and addressed her team. "Ladies, I have a bold and daring plan. There's no time for hesitation. My orders must be carried out without question..." Applejack looked and saw that Rainbow Dash, Twilight, and Pinkie were already headed down there. "Girls?" After sighing she just gave in. "Girls, wait up!" Now she jumped off the rooftop and followed the others.

While she was loading up the last crate the ponies jumped her. They all readied their weapons and Rainbow was the first to speak to her. "Okay we can do this the easy way or, my vote, the hard way."

Twilight the stepped in. "Yeah, look at it logically. There are four of us and one of you. What are you gonna do?" Just as she said that the girl then surprised them by pulling out one of those weird laser guns that those strange men had.

Rainbow Dash turned to Twilight. "You HAD to ask!"

She then fired the laser gun and them taking them by surprise. While this was happening she got back in the van, started it, and drove off. "Quick after her." Applejack said getting them all to go after the van. They thought it was best to take the rooftops so that way they won't lose the van, thankfully they were making great track. She thought she lost the ponies but when she looked in the mirror she saw them on the rooftops, so she rolled down the window and fired the laser gun at them again. Trying to make sure that they don't get hit they also slow down a bit and now the van was nearly lost. With time running out Applejack pulled out one of her ninja stars. "Not gonna let you get away." She said as she throws it.

Applejack made a successful throw as the ninja star popped one of the van's tires, making it crash and flip over. Knowing that this was the only lead they had to rescue those humans they went to the van and search for something useful.

Wondering if the one that drove the van was OK after that they hid behind a building. Applejack made some hand jesters to tell the others what to do. Unfortunately none of them knew what she was talking about.

Rainbow Dash was the one that broke the silence. "I. Don't. Know. What. That. Means." She said while making fake hand jesters.

Applejack was annoyed by what she did and just said it. "Go around back."

"Why didn't she just say so?" Pinkie asked.

While searching Rainbow Dash opened the back of the van and a canister fell out and rolled near Pinkie. When they all looked at it they were all shocked by what came out of the van. The canister that came out of the van had the same goo that turned them all into mutants. Pinkie knew this just immediately.

"Dad?"

To be continued
