When Tracksuit, or Ethan Casey, a mid-ranking C Class Hero of America, finds the Mane 6, CMC, Diamond Tiara, and Silver Spoon that were suddenly sent to Earth by a magic crystal, let's just hope things don't end up more than he bargained for.

A mid-ranking C Class Hero of America, Tracksuit (only called that because he always showed up in a tracksuit), or Ethan Casey to the very few friends he has, trained by a unique martial arts master turned hobo since his childhood, this man trained him to only use his skill to help. One day, Ethan was called to investigate a mysterious energy spike near his home, only to find anthropomorphic ponies in a crater.

How they got there was because the CMC (this includes Babs Seed) had found a magic crystal growing near their, unfortunately, Silver Spoon and Diamond Tiara found them and began the normal bullying and name-calling that then began leading into a fight breaking out, to where the Mane 6 got involved to separate them, but the magic crystal didn't react too kindly to being tossed around during the fight.

After a magical explosion, the group of mares and fillies get sent to Earth, Ethan takes the group into his apartment, thinking of it as a challenge to take care of something that doesn't threaten all life, but he may be over his head with this self-given mission.

Chapter 1: From Equestria To Earth

It was a normal day in Ponyville. The Mane 6 were walking toward Sweet Apple Acres after being told that Diamond Tiara and Silver Spoon were heading toward the CMC HQ, which would only end when somepony broke an arm.

Twilight had a slim hourglass body and stood at 6'9. Her attire is a baby blue button-up shirt just barely concealing her C-cup bust, a short skirt the same color as her eyes that does little to hide her plump bubble butt, black stockings, and black high heels.

Applejack, the tallest of the group standing at 7'1, had a very muscular body, her mane, and tail with both being tied off by red bands. Her attire is an open red plaid shirt showing off her G-cup bust, blue jean overalls hugging her body showing her toned curves and big thick flank, an old brown stetson hat rested atop her head, and light brown Cowgirl Boots.

Rainbow Dash, the second tallest standing at 6'11, had a slim athlete's body. Her attire is a blue hoodie with yellow sleeves zipped up hiding the DD-cup breasts, dark blue biker shorts showing off her toned legs and flank, and blue and black running shoes.

Pinkie, the second shortest standing at 6'6 with a slightly chubby yet curvy pear-shaped body. Her attire is a long-sleeved bright purple shirt with white rings on the sleeves and a cut in the middle showing the cleavage of her EE-cup boobs, a pale violet skirt, knee-high blue, and yellow ringed socks with pink strapped shoes.

Rarity, standing at 6'10 with a smooth curvy apple-shaped figure. Her attire was a ruffled light blue blouse barely concealing her F-cup bust, a shin-length black skirt with a split showing off her legs and thick flank, thigh-high black lace stockings with black high heels, and some blue eye makeup on her already beautiful face.

Fluttershy, the shortest of the group standing at 6'4. Her attire is a large green sweater covering her DDD-Cup bust, blue jean pants that hug her wide shapely hips with a picture of her cutie mark on said hips, and a pair of brown sandals on her feet.

"Alright, girls, let's get there and at least stop the fight," Twilight said.

"So AJ, how's life been since Babs moved in?" Rainbow asked.

"It's like living with a second Applebloom, only Bads is a little more violent, ah had to patch up her upper lip after she tried to fight a wild boar that got too close to the farm, and I think she's rubbing off on Applebloom," Applejack said, Fluttershy silently hoped the boar was okay.

The 6 got to CMC HQ to find the 18 to 19-year-old fillies were acting around 1/4 their age, with Silver Spoon face down in the mud and Diamond Tiara in a very painful looking submission hold while the other 3 CMC members watched it go down.

Applebloom, the second tallest standing 4'8, had a growing muscular body but wasn't anywhere near her sister's level and a somewhat developed AA-cup bust. Her attire consisted of a bright golden blouse with blue overalls. a black barrette with a red ribbon, and a pair of white and green shoes.

Sweetie Belle, the second shortest standing 4'6, had a growing smooth curvy apple-shaped figure like her sister with a well-developed B-cup bust. Her attire consisted of a lavender blouse with a matching skirt, knee socks, and shoes.

Scootaloo, the shortest standing 4'5, had a slim athlete's body like RD with an underdeveloped small A-Cup bust. Her attire consisted of blue jeans, blue running shoes, and a white sleeveless shirt with cloud patterns under a sleeveless jacket.

Babs, the tallest standing 4'10, had a toned athlete's body with a growing AAA-Cup bust. Her attire consisted of a black shirt and blue shorts, grey sneakers, and well as fingerless sports gloves.

Diamond Tiara, standing at the same height as Sweetie Belle, had a curvy figure with an AAA-Cup bust. Her attire consisted of a pink blouse with a crystal tiara on it and a skirt and heels to match.

Silver Spoon, standing at the same height as Applebloom, had a leaner curvy figure with an AA-Cup bust. Her attire consisted of her glasses, a grey shirt with a unique Silver Star design that was fashioned with glitter, and grey shoes.

Silver Spoon also picked out a pair of shorts to match the shirt. But she was also covered in mud and bruises, the latter of which Fluttershy began to tend to.

Twilight clapped her hands to get their attention ad said, "Alright, break it up, girls, break it up."

"Not until I get a sorry from this one!" Babs yelled back, tightening her grip on DT's leg.

"Never!" DT yelled despite the pain she was in, Pinkie then noticed a crystal on the ground, when she zipped over and picked it up, she found it was both humming and vibrating lightly.

"Hehe, what's this thing?" Pinkie said getting tickled by the vibrations.

Scootaloo walked up to Pinkie and said, "It's a crystal we found growing near our treehouse, we were going to use as a decoration then these two showed up and Babs dropped it to fight them."

Then DT grabbed and threw a rock at Babs' face but missed and the rock hit the crystal, causing it to hum louder and vibrate harder, it even began to heat up and glow, Twilight seemed to know what it was about to do.

"Everypony get, it's going critical! It's gonna blow!" she roared but it was too late, as Pinkie dropped it from the heat being too much for her hands to handle and it cracked on impact with the ground, immediately causing it to explode, the blast was so big it could be seen from the Crystal Empire.

On earth, in America, notably City G, right around where New York would be, there was a 6'11 lean and muscular young man with black eyes and black spiky, swept-back, unkempt hair, and fair skin, wearing a green tracksuit with white stripes around the sides and white sneakers. He was jogging down the street to a farmers market.

He stopped in front of the produce shop, the store manager said with a smirk, "Ethan! Welcome, how is our local Hero, Tracksuit, doing?" the manager laughed at the Hero Name Ethan had.

Ethan sweatdropped and replied, "Hey, it's not like I picked that name, I only got it because I show up in a tracksuit most of the time. I'll have the usual."

"You mean all of the time." the manager said while putting several eggs, milk cartons, steaks, and rice bags in some bags before handing them off to Ethan as he gave the money to pay for the food. "Pleasure doing business."

Ethan left the farmers market and continued down the street with his food, then his phone rang, when he looked at the caller ID it said, "Hero Association", Ethan answered the call and a stern male voice came through.

"C Hero Tracksuit, are you there?" the voice said, much to Ethan's dismay of his nickname being said so formally.

"Yes, Director... And please just call me Ethan." Ethan replied.

"Doesn't matter, the Hero Association scanners have picked up a massive energy spike in your area, investigate it-"

[THOOOOOMMMM!!!!]

The Director was cut off by the explosion before continuing, "Don't hang up, find out what that was and report!"

Ethan quickly ran to the explosion site, an empty parking lot, and spotted an odd sight, the Mane 6, CMC, Diamond Tiara, and Silver Spoon were standing where the explosion happened, Ethan hid behind a low wall and watched them.

"Look at what you did!" Babs yelled tackling Diamond Tiara, putting her in a headlock.

"I didn't do anything, now let go of me!" Diamond Tiara yelled fruitlessly trying to escape Babs' grasp.

Applejack immediately separated the two before the Mane 6 began looking at their surroundings, "Did we end up in Manehatten?" Rainbow Dash asked, before flying above the buildings.

"Rainbow, get down here! We can't let ourselves be seen just yet!" Twilight yelled using her magic to make Rainbow Dash fly back down.

"Director, I've found something, 12 anthropomorphic ponies, not horses, their muzzles are too short. There seem to be three different kinds, normal ponies, well as normal as you can get with an anthro, Unicorns with the ability to use something similar to PSI, and Pegasi with wings for fast flight. 6 are in their early 30s to late 20s, the other 6 are most likely 18 to possibly 19." Ethan said into his phone, failing to mention the fact he was staring at the Mane 6's hips and breasts.

"Okay, you're on a live satellite feed. Approach calmly and try to talk with them. If things get ugly, use force." the Director said, Ethan hung up his phone and came out of hiding, the ponies not noticing him when he did.

"Excuse me." Ethan said causing them to jump at the sound of his voice, "Are you all alright, especially you with the bruises, do you need any help."

"Piss Off!" Rainbow yelled immediately not trusting Ethan.

"Woah, Hostile," Ethan said raising his hands in defense.

"Don't know what the hay you are but get gone!" Applejack yelled.

Twilight facepalmed and thought, 'It's always the same crap with these two! Getting violent at a moment's notice!'

"Now now, there's no need to get rowdy. But seriously, is that one okay?" Ethan said still focused on Silver Spoon's beaten condition, she hasn't even woken up since the fight ended. Ethan approached them but Rainbow stepped in front of him and punched him in the face, smirking at her seemingly successful hit only to find that Ethan had grabbed her wrist and was twisting it.

Rainbow tried her best to act like it was nothing but the pain was too much, "Ow Ow Ow! Let Go!" she roared in pain as Ethan's grip and twist only got stronger, but Ethan released her so he could dodge Applejack trying to kick him, Rainbow rubbed her wrist and said, "Thanks AJ, think my wrist would've broken he that kept up."

"That varmit is quick, don't get caught a second time." Applejack said Twilight double face palmed this time, she looked at the others, who were acting the same way, untrusting and ready to attack, minus Fluttershy.

She was just cowering being a lamp post, that obviously didn't hide her, also Applebloom and Babs, Applebloom seemed just as angry at the two as she was, Babs was looking at Silver Spoon with worry on her face cause Silver Spoon still hadn't woke up yet.

'Now their fighting, this is like that time with Zecora, only worse.' Twilight thought then she created a Magic barrier around them, only Rainbow and AJ weren't inside.

"Good idea, Twi, protect the fillies while we-"

"This isn't for what you think it is Rainbow." Twilight said, then her eyes fell on Ethan and she thought, 'It's to keep anypony else from joining in. He'll have a hard time against these two, doesn't help that stallions are known to almost always be weaker them mares with only a few exceptions, but then again, he's not a pony.'

Suddenly Twilight senses something around Ethan, she enchanted her eyes to see what it was, she saw a firey red aura around Ethan, Twilight train of thought immediately began wondering, 'What is that?! Some form of this world's magic?! If so, why is it invisible to the naked eye?' Twilight wasn't even focusing on the fight as it started.

Rainbow and Applejack charged at Ethan and went on the offensive, Rainbow throwing fast punches and AJ with a strong series of kicks, but Ethan dodged each oncoming attack like they were coming at him in slow motion. Then he grabbed Rainbow's wrist again giving it a slight squeeze making her into charging forward to try and force a release, but she fell into a trap. Ethan then spun around Rainbow, swapping places with her faster than AJ could react because she ended up kicking Rainbow in the gut, launching her into a lamp post.

"Ooo, Sorry Rainbow!" Applejack said dropping her guard, then Ethan followed up with a strong upward slap to the back of AJ's leg she left sticking out, causing her to lose her balance as her leg was forcefully raised over her head, then Ethan reared back his fist putting one hand over it seemingly causing it to start steaming, Twilight noticed that his aura was building up around the fist.

Ethan then said, "First comes rock! Gū! Ja! Ken!"

Rock Slide Gatling!

Ethan then delivered a Gatling of devastating punches to the thigh, back of the knee, and the calf of AJ's defenseless right leg added with a twisting arm making each hit like a drill punch, giving her the mother of all charlie horses. AJ could barely move her leg due to the immense pain she was in, then Ethan said, "You seem to always put your right leg forward with both attacks and simple movement, your attacks were also less like proper attacks and more like a habit, and you also waste a lot of energy on pointless movements with your attacks. Those facts are how I was able to beat you."

"How about me!" Rainbow yelled with only a little breath, she had flown up to the clouds, Rainbow then kicked the cloud with everything she could muster. Making the cloud fire a massive lightning bolt at Ethan, when it hit Ethan couldn't be seen in a field of blue lightning, Rainbow charged full speed, but then at the last second. The lightning field clear, revealing a now shirtless Ethan with his hand opened flat like a chop, with his palm facing upward, and reared back. Twilight could see Ethan's aura had changed from a fiery orange aura to an electric blue aura that had absorbed the lightning bolt.

Ethan then said as Rainbow quickly tried to make a U-turn, "Second comes paper! Gū! Ja! Ken!"

Lightning Paper Kuni!

Ethan swiped his hand at Rainbow launching dozens of Kunai-shaped lightning bolts made of his aura, Rainbow took to the skies but the aura Kunai followed her. They were hot on her tail and gaining, when she made a sharp turn they made a sharper turn when she when faster they went even faster. Then Rainbow tried to backflip over the aura Kunai, but the aura Kunai immediately changed direction and hit her exposed back.

"You're too arrogant and far too over-confident, you look down at your enemy and underestimate them, even if they have something you don't, you still underestimate your opponent." Ethan said as Rainbow barely recovered from the hit, he thought, 'So the Pegasi can manipulate the weather with their hands, this one seems to be tougher then the others, probably due to some accidents she must've had.'

"Oh yeah!? Let's try this!" Rainbow flew far away before stopping and flying right back at Ethan, picking up speed as a sonic cone formed around her, then she created a sonic boom that also bent light to make a rainbow, Rainbow's mane seemed to make a rainbow as she moved.

Rainboom Ram!

Rainbow crossed her arms, readying herself for impact, but then Twilight noticed Ethan's aura change again, this time into a stiff and stone-like orange aura as he took a sumo starting stance, Ethan then said, "First comes rock! Gū! Ja! Ken!"

Immovible Mountain!

Ethan suddenly cracked the ground under him then Rainbow rammed straight into Ethan but the hero didn't even budge, not even his hair moved from the wind made by the impact, Rainbow bounced off Ethan and landed on her back, her head was practically splitting open.

"Your attacks seem to also be less effective as attacks and more for show," Ethan said, then the two mares were barely able to stand up, AJ's leg had barely recovered from the mother of all charlie horses and Rainbow's head was still practically splitting open, then Ethan extended two fingers.

Twilight saw his aura changing to a white glow, and he said, "And finally. Third comes scissors! Gū! Ja! Ken!"

Shear Scissors!

Ethan made a pair of scissors with his aura, only Twilight could see it, but Ethan made it known with one swipe at the two mares, their manes and tails were given a haircut.

Applejack losing the most hair, and their clothes were cut to ribbons, Ethan seemed to fully enjoy the view he was getting, the two mares covered themselves the best they could.

"You perverted son of a bitch!" Rainbow said, her blush made her face like an apple, Applejack was as red as the shirt she was wearing.

Ethan snickered and said, "I have my moments of niceness, my moments of jackassery, and my moments of perversion. I'm not some white knight, you're gonna have to go back in time for those kinds of heroes. Also, you kinda deserve it since you attacked me without reason."

"Noted." Rarity said then she looked at Applejack, "Darling, you... Look rather cute with short hair."

"Shut up and get me some clothes!" Applejack yelled with her blush, Twilight had an idea and smirked as her horn glowed and the barrier went down.

Clothes Beam!

Twilight shot the two mares with a beam of light and created clothing that perfectly fit them, but one thing was different, the clothing was frilly pink dresses that were so girly not even Rarity or Diamond Tiara would put them on.

"What the hell Twi!?" Rainbow yelled, preferring to be naked than in this.

"That's your punishment for randomly starting a fight with him, don't worry about any injuries on our part, I've already cast a healing spell on them, and Silver Spoon was healed during the fight," Twilight said motioning to a fully healing and wide awake Silver Spoon.

"Great, now I'm guessing none of you have a place to stay," Ethan said to which Twilight smiled.

"Well, we've been sent here from our own world, so we've got nowhere to go, so we'll be happy to take you up on your offer," Twilight replied before giving a glare to the others, "Won't we girls?"

The other ponies nodded in fear of Twilight and the girls followed Ethan to his apartment.

It wasn't big but it wasn't small, only about 3 rooms, there wasn't much in it either, just a few futons, a flat-screen TV, and the basic things an apartment needs, like a kitchen and bathrooms.

"You'll have to find something to sleep on, I'll buy some air mattresses when we go to the mall,"

"Thank Celestia!" Applejack said thinking she'll be able to get out of the dress she was in.

"Tomorrow, the mall is closed on Mondays." Ethan continued.

"Luna dammit!" Rainbow Dash and AJ yelled.

"Oh, you two are just upset cause you got your flanks handed to you." Pinkie happily and bluntly said.

"No, I am not- Okay a little," Rainbow said, then a click followed by a flash from Ethan caught RD's and AJ's attention, he had taken a picture of them with his phone before they knew what he did, he posted it online.

"Who would like to see the most embarrassing moment of these two's lives put on for everyone to see forever?" Ethan said showing the picture to which the others laughed while RD and AJ chased him around the block.
