Author's Notes:

A fanfiction I decided to make when I discovered that Rainbow Dash is so far the only character of the Mane Six who does not have a sibling, so I made one of my own, another source of inspiration for creating this character was watching Saitama do the fitness test in One Punch Man, hope you all enjoy.

It was the time of the year where the Sisterhooves Social was going to be held at Sweet Apple Acres again, the Mane Six have made a deal with one another to participate with their biological siblings, Twilight Sparkle was going to team up with Shining Armor, Fluttershy was going to team up with Zephyr Breeze, Pinkie Pie was going to team up with Marble Pie, with Maud Pie and Limestone Pie acting as another team, Rarity was going to team up with Sweetie Belle, and Applejack was going to team up with Apple Bloom, Rainbow Dash looks and realized that she did not have a biological sibling of her knowledge, and thus, could not participate, she felt left out just like when she discovered she was the only one of her friends who did not have a pet,

"Rainbow?" Scootaloo asked from behind, she soon catches up to her,

"Why can't I participate?" Scootaloo asked,

"Because I made a bet with my other friends to participate with my biological siblings, and I don't have any, I'm sorry, Scootaloo, but I can't team up with you this year." Rainbow Dash replied,

Scootaloo was very sad, Rainbow Dash had sympathy for her, Derpy then crashes between the two and comes back, she had an envelope in her mouth,

"Mail for Rainbow Dash." Derpy said muffled,

Rainbow Dash takes it and sees it was from Bow Hothoof and Windy Whistles, her parents,

"Why does your mom and dad want to see you?" Scootaloo asked,

"I don't know, I'll be going, take care, Scootaloo." Rainbow Dash replied,

she flies to her home while Scootaloo and Derpy wave bye at her.

Rainbow Dash arrives at her home and enters,

"Mom, dad, I'm home." she said as she walks forward,

she looks and sees a few balloons and a banner at the top,

"Welcome home... Lightning Blaze?" Rainbow Dash read out loud,

her parents hear her and go to her,

"Rainbow Dash, you have an older brother, he left us before you were born." Bow Hothoof said,

"Why didn't you two tell me?" Rainbow Dash asked,

"Well... uh, you see, Rainbow, your brother is not a normal Pegasus." Windy Whistles replied nervously,

"What do you mean?" Rainbow Dash asked,

the door opens behind her before Windy Whistles could answer,

"I'm home." a male voice said,

Rainbow Dash turns around and sees a Pegasus who looked almost just like her, but he was more muscular, his coat was the same color as Bow Hothoof, he had a rainbow mane and tail as well, but his mane was short, and his eyes were dark purple, Rainbow Dash looks at his outfit and sees he was wearing a light blue outfit with white cloud patterns on it, black mid-calf length boots on his hind legs, and a very light blue belt with a blue buckle on his waist, Rainbow Dash sees patches on his outfit's chest,

"Lightning Blaze" the right patch read,

Rainbow Dash looks at the left patch and gasps,

"Cloudsdale Air Force" the left patch read,

Rainbow Dash could not believe it, she had a brother in the military,

"Oh my gosh, oh my gosh, oh my gosh, oh my gosh, oh my gosh." Rainbow Dash said while flapping her wings,

Lightning Blaze looks at her,

"Oh right, mom was pregnant when I left." Lightning Blaze said,

"Lightning Blaze, meet your little sister, Rainbow Dash." Windy Whistles said,

"Have you two ignored her as well?" Lightning Blaze asked,

"No, they supported every little thing I did, it was embarrassing." Rainbow Dash replied,

"Well, lucky you, they didn't support me on anything I did." Lightning Blaze said,

"Now, now, Lightning Blaze, that is our fault, and we're sorry, we didn't know how to raise a child back then." Bow Hothoof replied,

"Well, you should've learned before you had me." Lightning Blaze said while glaring,

"Lightning Blaze, calm down, we know you're upset about that, but we have learned, your sister has achieved a lot." Windy Whistles replied,

"I'd like to hear about this." Lightning Blaze said,

he sits and his family joins him,

"Well, big brother, I am very excited to meet you, I have saved Equestria several times, I am the element of loyalty, I'm also the fastest flier in all of Equestria, and most of all, I'm a Wonderbolt." Rainbow Dash said,

Lightning Blaze looked at his sister with a confused look,

"Wonderbolt?" Lightning Blaze asked,

Rainbow Dash becomes very shocked,

"You never heard about the Wonderbolts?! Where have you been?!" Rainbow Dash asked,

"No, of course not, I just came back home from fighting in a war between the Pegasi and the griffins, of course I'm not going to have time to hear about them." Lightning Blaze replied in an annoyed tone,

Rainbow Dash was a bit shocked but impressed at the same time, she'd like to hear about her brother's stories in the military one day, but she focused on the topic at hand,

"They are only the coolest and most awesome group of flying Pegasi in all of Equestria." Rainbow Dash said,

"I'd like to see this." Lightning Blaze said, Rainbow Dash becomes extremely excited,

"Go on, Rainbow, take your brother to see it." Windy Whistles said,

"Yeah, I think they'll be happy to meet him." Bow Hothoof said,

Rainbow Dash nods and she flies to the Wonderbolts Academy with Lightning Blaze.

Spitfire was doing a roll call with Soarin and Surprise, among the cadets were Lightning Dust and Bulk Biceps,

"You here, Mr. Biceps?" Spitfire asked,

"YEAH!!" Bulk Biceps yelled,

"Lightning Dust?" Spitfire asked

"Here, ma'am." Lightning Dust replied

"Rainbow Dash?" Spitfire asked just before she arrived behind her,

she turns around and the others look with her,

"Sorry, ma'am, but I've brought a special guest with me today." Rainbow Dash said,

Lightning Blaze walks forward, the other Wonderbolts gasp,

"Oh, Celestia, he's from the Cloudsdale Air Force." Soarin said,

"Wow, who is this, Rainbow Dash?" Surprise asked,

"My fellow Wonderbolts, I give you, Lightning Blaze, my big brother." Rainbow Dash said,

the other Wonderbolts gasp in surprise at the fact that Rainbow Dash had a brother in the military,

"Hello, my name is Lightning Blaze, I just retired from the Cloudsdale Air Force after twenty years of service, I have never heard of you guys, so I come to watch, and if there's space, join, I don't have a job." Lightning Blaze said,

the other Wonderbolts laugh,

"Sure, anypony who is from the military is more than qualified in my book." Spitfire replied,

Lightning Blaze smiles and gets in line with his sister to his right, he puts on a mask he wore in the air force to protect himself while flying, it had the same pattern as his uniform,

"Uh, Rainbow, your uniform." Soarin said,

"Oh right, excuse me a minute." Rainbow Dash replied,

she flies into the academy and soon comes out wearing her uniform, her mouth and mane were exposed, Lightning Blaze's mane was also exposed on his uniform, but his mouth was covered, his wings were out on the sides of his uniform, and his mask had black goggles built into the eyes of the mask, while the other Wonderbolts had to put on light blue goggles with yellow straps,

"Okay, five hundred laps, ready go!" Spitfire said,

they all start flying, Lightning Blaze does the sonic rainboom immediately once when he started flying, he also had rainbow electricity come out on his body, the Wonderbolts all stop flying and look on in shock, Spitfire times Lightning Blaze and was shocked that he finished the course in five minutes, Lightning Blaze was a blur when he flew, he was only able to be spotted by the rainbow electricity around his body, Rainbow Dash looked in shock along with the other Wonderbolts, she was shocked because her brother did not need to fly and gain speed to perform the sonic rainboom like how she had to, he can just do it by flying,

"Next, clear the sky of clouds, ready, go!" Spitfire said,

Lightning Blaze takes off and already clears the sky of every cloud, everyone was shocked, Spitfire looks at her stopwatch.

"My goodness! Less than a second!" Spitfire said,

the other Wonderbolts were shocked, especially Rainbow Dash, her pride was already hurt, she was known as the fastest flier in Equestria, but it seemed like there was somepony even faster than her, Lightning Blaze lands,

"Is there anything more challenging here?" he asked, Lightning Dust flies forward,

"There's the dizzitron." she said, Lightning Blaze smiles under his mask,

"Let me try it, maximum power." he said, the Wonderbolts gasp in shock, they get it out,

"You asked for it." Spitfire said,

Lightning Blaze goes on it, it is turned up to maximum power and Lightning Blaze spins, rainbow electricity appears on the dizzitron and makes it go even faster, the others were in shock, Lightning Blaze is flung into the air when the dizzitron explodes, he goes up and then flies back down immediately, Spitfire looks at the stopwatch,

"One second, wow." she said with impressment, the other Wonderbolts were shocked,

"That's all for now, go to the mess hall." Spitfire said, and everypony goes and has lunch,

"Lightning Blaze, I'm proud of your achievements, but please give me time to shine too." Rainbow Dash said,

"I'm actually kind of disappointed in you." Lightning Blaze replied, Rainbow Dash stops eating from shock,

"What? Why?" Rainbow Dash asked,

"Here you are doing training for something called the Wonderbolts, which just puts on shows for others to watch, I actually fought in a war and survived, this training is nothing compared to the training in the Cloudsdale Air Force." Lightning Blaze replied a little annoyed,

Rainbow Dash was angry, her pride was hurt yet again,

"Fine, since it's so easy for you, let's see you do the obstacle course." Rainbow Dash said,

"Maybe I will." Lightning Blaze replied,

the other Wonderbolts were looking at them, they were excited to see Lightning Blaze do the obstacle course, lunch finishes and everypony goes outside, the obstacle course was ready,

"Okay, Lightning Blaze, remember, this isn't a race, and do your best." Spitfire said, Lightning Blaze gets ready, confidant in his ability,

"Go!" Spitfire said, and Lightning Blaze takes off,

he goes through the cloud hoops quickly, everypony sees more electricity on Lightning Blaze than usual, he then does another sonic rainboom, the Wonderbolts gasp in shock, but unlike the first sonic rainboom, this one created a circle of rainbow fire, Lightning Blaze also left a trail of rainbow fire behind him, and had rainbow electricity engulf his entire body, he flies extremely fast, he flies past the obstacles and destroys them with his speed and rainbow fire, he sees the debris in the sky and dodges them all easily, the others were surprised at how agile he was, he finishes the obstacle course while the others looked at him with jaws dropped, not only was he faster than Rainbow Dash, he was more agile as well, Rainbow Dash's anger went up again, she felt insulted, they hear screaming in the sky and see the other Pegasi in the sky were on fire, the flames were rainbow, they were screaming to have it put out, the other Wonderbolts use rain clouds to douse the fire,

"Wow, Lightning Blaze, I've never seen anypony as fast as you, you really are Rainbow Dash's sibling, but now that we saw your physical capabilities, you still have to show your mental capabilities, we have a test coming up, make sure you study." Spitfire said, and she walks away,

Rainbow Dash had a smile on her face, she flies in front of her older brother,

"You better brace yourself, brother, I always pass my tests." she said,

"So do I." Lightning Blaze replied,

the other Wonderbolts can see sibling rivalry going on between the two, they all go in to take off their uniforms and study, Rainbow Dash spends her time studying for the test while Lightning Blaze shows off, Bulk Biceps lifts the heaviest weight he can lift,

"YEAH!!" he screamed,

the barbell he lifted had a big weight, a medium weight, and a small weight on each side, the other Wonderbolts cheer, Lightning Blaze then lifts up weights and the others gasp,

"Rainbow Dash, you might want to see this." Lightning Dust said,

Rainbow Dash flies out, she looks on in shock, Lightning Blaze has lifted two barbells, with five heavy weights on each side, he lifted them with one front hoof, the others see he also had a third barbell of the same weight on his back, Rainbow Dash's pride was hurt a little, he was stronger than her as well, Rainbow Dash decides to go back to studying, she hears cheering and gets distracted, she goes out to see what it was, she sees Lightning Dust and Lightning Blaze doing actual acrobats, Lightning Blaze does somersaults, front flips, backflips, and side flips, he was not flying to do them like how Lightning Dust was, Rainbow Dash did not mind because acrobats was never really her strong suite, but she can see that Lightning Dust's pride was hurt as well, she goes back and keeps studying, she then hears banging on tables and heads out again, she sees Lightning Blaze was hoof wrestling the other Wonderbolts, he beat all of them easily, but he hurt their front legs in the process, Rainbow Dash was a bit shocked, she goes back to studying, it was soon test time and everypony takes the test, Surprise gives back their papers, Lightning Blaze was sitting beside Rainbow Dash to her right, his mask was off, everypony can see that the two looked extremely similar in their faces, but Lightning Blaze was a bit bigger and a little more muscular than Rainbow Dash, Rainbow Dash gets her test back and sees she has just barely passed, she sighs in relief, Lightning Blaze gets his paper back and Rainbow Dash looks at his grade in shock,

"What? A perfect score?!" Rainbow Dash asked in shock,

"Got a problem?" Lightning Blaze asked while smirking,

"Yes! I studied and barely passed, while you goofed off, didn't study, and got a perfect score, it's not fair!" Rainbow Dash replied angrily,

"I think this proves I'm smarter than you." Lightning Blaze said,

Rainbow Dash growls and groans in anger, she knew she could not accuse Lightning Blaze of cheating because she watched him during the test, Spitfire then goes to them,

"Sorry, Rainbow Dash, but I have to strip you of your rank, your brother has proven himself to physically and mentally better than you." Spitfire said, and Lightning Blaze is made the lead pony, Rainbow Dash growls in anger,

"That's it, I'm going home, Lightning Blaze, you're coming with me." she said, and she flies home while dragging him along, the other Wonderbolts watch in worry, sensing jealousy from Rainbow Dash.

The two ponies arrive at Rainbow Dash's home and Lightning Blaze walks around, he sees Tank,

"I didn't think you'd have a pet turtle." Lightning Blaze said,

"It's a tortoise." Rainbow Dash replied a little annoyed, tired from people getting them mixed up, Lightning Blaze shrugs,

"I'll be taking you to the weather factory after I take a shower, it's where I work, maybe you can get a job there." Rainbow Dash said,

"Okay then." Lightning Blaze replied, and Rainbow Dash goes into the bathroom to take a shower, which she hated, Lightning Blaze walks around the house and sees nothing of interest, he soon had to use the bathroom as well, he enters the bathroom while Rainbow Dash takes a shower, she was behind the curtain and the bathroom was filled with steam, she screams,

"LIGHTNING BLAZE!! I WOULD LIKE TO HAVE SOME PRIVACY!!" Rainbow Dash yelled,

"Sister, if you were in the air force like me, you would always have to share the bathroom with more than one pony." Lightning Blaze replied calmly,

the very thought horrified her, Lightning Blaze sits on the toilet and uses the bathroom, Rainbow Dash washes herself while uncomfortable, Lightning Blaze finishes up quickly and flushes the toilet, he washes his front hooves just when Rainbow Dash finishes her shower, she had her mane completely wet, and a towel on her back, she dries herself and sees Lightning Blaze has taken off his uniform, she looks at his cutie mark and sees it was a white cloud with a lightning strike coming out, it was red, blue, and yellow, but the lightning strike was made out of fire, Rainbow Dash was a bit surprised that her brother's cutie mark was very similar to her own, she then sighs,

"Okay, Lightning Blaze, follow me." Rainbow Dash said, and they go outside and fly to the weather factory.

The two arrive in Cloudsdale and go to the weather factory where Rainbow Dash works,

"Oh, this place, it's been a while since I've been here." Lightning Blaze said,

"What?! You've worked here before?!" Rainbow Dash asked in shock,

"Sure did." Lightning Blaze replied,

they go in and the Pegasi cheer in excitement at seeing Lightning Blaze, the manager of the entire factory goes to them,

"Lightning Blaze, good to have you back." the manager said,

"Nice to see you again too, boss." Lightning Blaze replied,

"When did my big brother work here?" Rainbow Dash asked,

"Twenty five years ago, before he left for the air force five years later, he was employee of the month every month for the five years he worked here, he was the best worker we ever had." the manager replied,

Rainbow Dash's pride was hurt even more, Lightning Blaze flies to work and makes the clouds faster than anypony, it was so fast, they were done hours before they were scheduled, Rainbow Dash was shocked again,

"See, Rainbow Dash, this was every day when your brother worked here, we always got to go home early because of him; Lightning Blaze, I'm giving the manager title back to you, sorry, Rainbow Dash, but I'm going to have to demote you to assistant manager because you have not been able to keep up with your brother's capabilities." the manager said,

Rainbow Dash growls at the fact that he can do her job better than she can as well while the other Pegasi cheer,

"Enough! I'm tired of hearing the things my brother did and him outdoing me, I've been embarrassed all day!" Rainbow Dash said angrily, Lightning Blaze flies to her,

"Embarrassed? Oh please, I can embarrass you easily." Lightning Blaze replied,

"That's it, we're going back to mom and dad." Rainbow Dash said, and they fly home while the Pegasi watch in worry.

Rainbow Dash and Lightning Blaze arrive home and they see Bow Hothoof and Windy Whistles, they both land,

"Good job on your flying, Rainbow." Bow Hothoof said,

"You landed good too, yeah." Windy Whistles said,

Rainbow Dash was already embarrassed, Lightning Blaze glares at the two,

"See, you two support her over little things, I want it too." Lightning Blaze said,

"Lightning Blaze, we have our reasons, believe us." Bow Hothoof replied,

Lightning Blaze glares at them, Rainbow Dash realizes that Lightning Blaze does not get the support she gets from their parents, she was wondering why,

"We have to go get groceries, you two should come along, it'll be family time for us." Windy Whistles said,

Lightning Blaze and Rainbow Dash sigh and go to the store with their parents.

Rainbow Dash was pushing the shopping cart while Bow Hothoof and Windy Whistles got the items they wanted to buy, they cheer loudly at Rainbow Dash pushing the cart, the other Pegasi look on in surprise and snicker at Rainbow Dash due to her parents' over supportiveness, Rainbow Dash was so embarrassed right now, Lightning Blaze smiles and turns around and he pretends to cry,

"I want the support too." he said, he says the same thing two more times even louder while he jumps in the air the last time he says it, he was almost touching the ceiling, he grabs the shopping cart from the front and pushes it back and forth while pretending to cry like a toddler, he then screams and runs to the nearest stack of items and throws it on the floor, the floor partially broke from the impact, he then pretends to cry again while throwing hay on the floor from the food section, he then gets on the floor and stomps his hind legs on the floor while swinging his front legs around and was screaming like a child throwing a temper tantrum, his hind legs ended up breaking part of the floor, Rainbow Dash was extremely humiliated, her parents being supportive of her and her brother throwing a tantrum like a little kid were both in public, she looks around while sweating and sees the other Pegasi laughing, Rainbow Dash quickly gets the items and pays for them and heads on out while carrying Lightning Blaze out, they head back home and her parents continue to support her, Lightning Blaze stops the tantrum and looks at Rainbow Dash,

"I hope you now know the true meaning of embarrassment." he said with a smile on his face,

Rainbow Dash growls and puts the groceries down and flies to her home, Lightning Blaze decides to follow her, Bow Hothoof and Windy Whistles keep cheering and they stop when they realize their children were gone,

"Rainbow Dash? Lightning Blaze?" Windy Whistles asked,

they realize they had to unpack the groceries on their own, they sigh and get the groceries in the house.

Lightning Blaze and Rainbow Dash go to Rainbow Dash's home and Lightning Blaze decides to make things up to Rainbow Dash, he goes out and come back with a barrel of root beer and two mugs, he shows it to her,

"This was my favorite drink back in the air force, I think you might like it." he said, and Rainbow Dash tries a mug of the root beer, she became filled with joy,

"Wow, this is even better than the cider at Sweet Apple Acres." Rainbow Dash said,

"You don't sound like you get to have it often." Lightning Blaze said,

"I don't, it's because a pony named Pinkie Pie keeps hogging all of it." Rainbow Dash replied,

"I can deal with her for you." Lightning Blaze said,

"It's fine, big brother, I get back at her by not eating her pies." Rainbow Dash replied,

Lighting Blaze smiles, but Rainbow Dash finishes it and was still bitter about Lightning Blaze outdoing her at everything,

"I need some time alone." she said, and she goes outside and flies to Ponyville, Lightning Blaze watches her from her house.

Rainbow Dash flies to Ponyville and sees her five friends were meeting with their siblings, they gave Scootaloo a place to hang out with them because they felt bad she could not participate in the Sisterhooves Social this year, she sees Rainbow Dash flying and she lands, Scootaloo leaves them and runs to her, she sees Rainbow Dash looked upset, she goes to her,

"Rainbow Dash, what's wrong?" Scootaloo asked,

"Scootaloo, I have an older brother." Rainbow Dash replied, Scootaloo becomes filled with ecstasy and screams in excitement,

"Scootaloo, that's not the point." Rainbow Dash said, Scootaloo stops screaming in excitement,

"My brother is better than me at everything so far, I lost my rank at the Wonderbolts, I got demoted at work, and he embarrasses me more than my parents do." Rainbow Dash said,

"Have you tried competing against him in sports?" Scootaloo asked, Rainbow Dash thinks about and becomes happy,

"You know what, Scootaloo, that's not a bad idea, maybe there is something I am better at than him, you get to be the judge." Rainbow Dash replied, Scootaloo nods in excitement, Rainbow Dash flies back home,

"Lightning Blaze, follow me, I have something for you." she said, and he does,

they fly far and away from Ponyville, where there was nothing but flat land and grass everywhere, there were horseshoes, a rod in the ground, several barrels, two stacks of hay, two sports balls, a high striker, a tug of war rope, a tape measure on the closest tree, which was pretty far, two metal balls, a track, and a punching bag,

"Big brother, I challenge you to an Iron Pony competition." Rainbow Dash said,

"You're stupid if you think you can beat me." Lightning Blaze replied,

"Let's hear you say that after you lose." Rainbow Dash said, confidant in her abilities,

"Okay, first, horseshoe throwing, ready, go." Scootaloo said,

Rainbow Dash throws the first horseshoe, it almost lands on the rod, Lightning Blaze throws the next one, not only does it hit the rod, the rod flies out of the ground and goes into a tree with the horseshoe, Rainbow Dash and Scootaloo look on in shock,

"Next, agility, go!" Scootaloo said,

Rainbow Dash runs around the barrels with no problem, Lightning Blaze smiles and runs around the barrels, but was a lot faster than his sister, he did not hit any barrels either, Rainbow Dash was already getting nervous,

"Next, hay throw, ready, go!" Scootaloo said,

Rainbow Dash throws it as far as she could, it landed on the ground, Lightning Blaze smirks again, he throws the next bundle of hay and it goes farther than the one Rainbow Dash threw, and gets lodged into a tree, Rainbow Dash and Scootaloo looked on in horror, she then looks at her brother and he smiles at her,

"Next, ball throw, ready, go!" Scootaloo said,

Rainbow Dash throws the metal ball and it lands into Ponyville, Flurry Heart sees it and tries to carry it, Shining Armor and Cadence chuckle and pick it up for her, they then play with it; Lightning Blaze then throws the other metal ball, it goes into the sky and hits Rainbow Dash's home,

"MY HOUSE!!" she yelled in horror, the others in Ponyville hear her and look at her home, they did not see the part of her home damaged from the ball Lightning Blaze threw, they shrug and go back to what they were doing,

Lightning Blaze smirks while Rainbow Dash was still in shock, Scootaloo looked on in horror, she was more scared of Lightning Blaze than excited to meet him,

"Next is the vertical jump, go!" Scootaloo said,

Rainbow Dash jumps to the top of the tape measure while Lightning Blaze jumps past it and his entire upper body goes into a tree branch, it was a lot higher than Rainbow Dash's jump, the two look in horror and Lightning Blaze flies out unharmed,

"Next is the balance test, go!" Scootaloo said,

the two balance balls on their noses, Rainbow Dash was having a little trouble, but Lightning Blaze outdoes her by balancing himself only on his left hind leg, with the ball on his muzzle, Rainbow Dash tries to do it too but falls, Rainbow Dash looks at him and growls, she was losing every competition,

"Next is the high striker, go!" Scootaloo said,

Rainbow Dash kicks it with her hind legs first, she hits the bell, Lightning Blaze goes next and kicks it with only his right hind leg, the high striker breaks and flies away, several ponies in Ponyville were conversing and the high striker flies past them, they look and watch,

"What the?" Twilight Sparkle asked,

"What in tarnation?" Applejack asked,

the bell is then hit and it breaks as well and flies as well, the high striker flies into a tree, the bell flies into a tree that was a lot farther, the other ponies looked on in shock, they look at where it came from but do not see anything, they were bewildered;

Rainbow Dash and Scootaloo were horrified, Lightning Blaze just smirked,

"Next thing is the tug of war, go!" Scootaloo said,

the two tug on the rope with their mouths, Lightning Blaze did not even try and Rainbow Dash could not bring him down, she grunts and tries to pull, Lightning Blaze smiled and tugged, it made Rainbow Dash's grip come loose and she flies into the air from the force of the tug and screams, she lands on the ground and breaks part of it, debris flies up into the air, she flies back while angry,

"Next is the punching bag, go!" Scootaloo said,

Rainbow Dash hits it as hard as she can with her right front hoof, it made the punching bag move back a lot before returning to its original stance, Lightning Blaze smirks while he walks to it,

"Amateur." he said, he punches it with his right front hoof and breaks the chains holding it, the punching bag flies into the air and goes all the way to the Cutie Mark Crusaders' tree house, the punching bag broke open and sand poured out, but it also demolished the tree house,

"OUR TREE HOUSE!!" Scootaloo yelled,

Apple Bloom and Sweetie Belle hear her and run to it, the others follow them, they see the tree house was destroyed, the others gasp,

"Oh my goodness." Cadence said,

"Look at that impact." Maud Pie said bluntly and stoically, they look and see a hoof mark that broke the punching bag,

"There is no way this could have been Scootaloo." Sweetie Belle said,

"This can't be Rainbow Dash either, she's nowhere near this strong." Twilight Sparkle replied,

"Fluttershy, big sister, if the Sisterhooves Social is like this, then this breeze does not want to compete." Zephyr Breeze said,

"It's okay, Zephyr Breeze, I'm scared too." Fluttershy replied,

"The only pony I can think of being this strong is Big Mac." Pinkie Pie said,

"But Big Mac is right here, who else in Ponyville could be this strong?" Rarity asked,

"There's nopony in the royal guard I know is capable of this, come on, let's continue celebrating for tomorrow." Shining Armor replied, and they walk away;

Rainbow Dash and Scootaloo were horrified,

"Next is the last one, the race, it's a run, so no flying." Scootaloo said, and they get into position,

"Ready, get set, go!" Scootaloo said, and they run,

Lightning Blaze was in the lead so far, Rainbow Dash was running as fast as she can, they keep running but Lightning Blaze then had rainbow electricity on him, he performs a sonic rainboom and runs really fast, Rainbow Dash stops and was in shock, Lightning Blaze stops at the end,

"I win." Lightning Blaze said while smirking,

Rainbow Dash was enraged, because her brother can perform the sonic rainboom without flying, he just needed to run, Rainbow Dash growls and flies away, she comes back with a thundercloud, she squeezes it and zaps Lightning Blaze, but he absorbs the lightning, it changes to rainbow color and goes back into the cloud and electrocutes Rainbow Dash, she screams and is shot away, Scootaloo was shocked, Lightning Blaze was immune to being zapped, Rainbow Dash flies down,

"THAT'S IT!! ONE MORE COMPETITION!!" Rainbow Dash yelled angrily,

"Name it." Lightning Blaze replied,

"Hoof wrestle!" Rainbow Dash said, Scootaloo was shocked,

"Prepare to lose." Lightning Blaze said while smirking,

Rainbow Dash goes to the nearest tree stump and places her right front leg on it, Lightning Blaze shrugs while smiling and grabs her hoof with his own right front hoof, they were even for now,

"Ready, go!" Scootaloo said, and they wrestle,

Rainbow Dash was struggling and grunting, she was sweating profusely as well, she could not move her brother's hoof, he smiles and then moves his hoof forward, his strength moves Rainbow Dash's leg off of the stump and he hears a crack, Rainbow Dash screams and her leg is smashed into the ground, the dirt flies up as well, Scootaloo looks on in shock and sees Rainbow Dash was screaming and crying in pain, her right front leg has been dislodged, it was out of place as well,

"I'll be at my old home if you need me." Lightning Blaze said, and he flies away,

Rainbow Dash cries in pain from the dislocation of her joint,

"You okay, Rainbow Dash?" Scootaloo asked,

"Contact my parents, Scootaloo, I need to ask them something, and get the doctor, I'm not okay at all." Rainbow Dash replied,

Scootaloo nods and runs as fast as she can while Rainbow Dash cries her eyes out, her pride was deeply hurt, her brother was better than her at everything, Scootaloo soon comes back with Nurse Redheart, they take Rainbow Dash to the hospital to examine her right front leg and put a cast on it, she was also given painkillers to get rid of the pain, she can walk again, but was limping,

"I hope Derpy delivers the mail right." Scootaloo said,

"Me too, I have something really important to ask my parents." Rainbow Dash replied,

"What is it?" Scootaloo asked,

"It's about Lightning Blaze, before I met him, my parents said he's not a normal Pegasus, I think it's about time I found out what's abnormal about him." Rainbow Dash replied, Scootaloo agrees and they walk together,

they arrive at the gathering in Ponyville, they were celebrating for tomorrow for the Sisterhooves Social, Scootaloo goes to Apple Bloom and Sweetie Belle, the others see Rainbow Dash limping

"Rainbow Dash." Rarity said, and her friends go in front of her,

"What happened?" Spike asked,

"I don't wanna talk about it." Rainbow Dash replied,

"We're your friends, Rainbow, you can tell us." Twilight Sparkle said, Rainbow Dash looks at their faces,

"It's... complicated, there are still things I have to find out about first as well, so please, give me more time, I'll explain once when I know everything." she said, the others agreed and go back, they celebrate while Rainbow Dash waits for her parents,

"Who would ask us to come here?" she heard Bow Hothoof ask,

"Who knows, I sure hope it's important." Windy Whistles replied, they see Rainbow Dash up ahead,

"Rainbow Dash." Bow Hothoof said while they run to her,

"What happened to your leg?" Windy Whistles asked,

"I tried to hoof wrestle my brother." Rainbow Dash replied, her friends stop what they were doing and look at her with surprise,

"Rainbow Dash has a brother?" Pinkie Pie muttered,

"Yes, he's scary." Scootaloo muttered, the others look at her for a second before looking back at Rainbow Dash,

"Mom, dad, I'm the one who asked you two to come here, I have something to ask." Rainbow Dash said,

"What is it?" Windy Whistles asked,

"Why? Why is my brother faster, stronger, more agile, and smarter than me?" Rainbow Dash asked, the other ponies except for Scootaloo look at her with disapproval, believing that she was jealous, Bow Hothoof sighs,

"I knew this day would come, you see, Rainbow Dash, as your mother said earlier today, your brother is not a normal Pegasus, he was born with a rare type of genetics that only one in hundred Pegasi get, these genes grant the Pegasus superpony speed, strength, stamina, endurance, and intelligence, along with complete immunity to electricity." Bow Hothoof said,

"What?!" Rainbow Dash asked with shock, her wings unfolding in the process,

"It's true, Rainbow Dash, your brother was born like that, he was able to perform the sonic rainboom ever since he was three by just running or flying, he didn't need to train a day in his life to perform it." Windy Whistles said,

"But what about this sonic rainboom he performed after the first one?" Rainbow Dash asked, her parents react with shock,

"Well, there's no use hiding it, what Lightning Blaze performed there is called a sonic fireboom, it's an advanced version of it, but it leaves behind a trail rainbow flames that destroys things and sets others on fire, the rainbow electricity is also something that comes with the sonic fireboom, as of now, only he can perform it." Bow Hothoof said,

"Why didn't you two tell me about him?" Rainbow Dash asked,

"We didn't want you to grow jealous of him, I'm sorry to say this, Rainbow Dash, but you weren't born with those superior genes like how Lightning Blaze was." Windy Whistles replied, Rainbow Dash's jaw dropped at the revelation,

"It's not fair! Why wasn't I born with it?!" she asked angrily,

"I'm sorry, you just weren't, there's no need for you to be jealous." Bow Hothoof replied,

"That's not the point, I got stripped of my rank in the Wonderbolts and demoted at work because of his superior physical and mental capabilities!" Rainbow Dash said angrily, her friends gasp in shock at the revelation,

"I'm sorry, Rainbow Dash, but your brother was just born that way, you're going to have to earn it back." Bow Hothoof said,

"But how?! He's faster, stronger, and more agile than me! He got a perfect score on a test without even studying, while I had to study all the time and barely passed! And he can clear the clouds in the sky in less than a second, it's not fair!" Rainbow Dash replied angrily with tears in her eyes, she starts crying, her friends run over to comfort her,

"Where is he staying now?" Windy Whistles asked,

"He said he'll be at his old home." Rainbow Dash replied tearfully,

"That's his apartment, it's right across from the store." Bow Hothoof said,

"Oh, I know where that's at, that's right across from my and Zephyr's parents' house." Fluttershy said,

"What's his apartment number?" Rainbow Dash asked,

"206." Windy Whistles replied,

"So his address is 206 Cloudsdale Apartments, that's easy to remember." Fluttershy said,

"Well, let's send a letter to him, I think this has to be settled out." Twilight Sparkle replied,

"That's everything, mom and dad, thank you." Rainbow Dash said,

"You're welcome, one more thing, Rainbow Dash, Lightning Blaze is the reason we always supported you over everything, we knew you wouldn't be able to match up to him, that's why we supported you, so you wouldn't be jealous of him." Windy Whistles replied, Rainbow Dash nods with tears on her face,

"Thank you." she replied,

"Well, we'll be heading home now." Bow Hothoof said, and they fly home,

"I am so sorry, Rainbow, I didn't know your sibling was a bully." Twilight Sparkle said,

"He's not, it's just that he outshines me at everything." Rainbow Dash replied,

"Sounds like somepony needs to be put in their place." Apple Bloom said,

"Eeyup." Big Macintosh replied,

"Thanks, guys, I'll be heading home now." Rainbow Dash said,

"You should, Rainbow, you sound like you've had a rough day today." Cadence replied,

Rainbow Dash flies home in tears and sleeps.

The next day comes and it was the day of the Sisterhooves Social, Derpy comes in and wakes up Rainbow Dash when she crashes, she looks and sees Derpy had a letter,

"Come to Sweet Apple Acres." it read, much to Rainbow Dash's confusion, but she flies there anyway, she arrives and lands, nopony was around, she looks and sees Lightning Blaze in front of her,

"Lightning Blaze, what are you doing here?" she asked

"I should be asking you that, I got a letter saying to come here." Lightning Blaze replied,

"I did too." Rainbow Dash said,

"Then who sent it?" Lightning Blaze asked,

"Ah did." a deep male voice replied,

they look to the west and see Big Macintosh walking over,

"Big Mac?" Rainbow Dash asked,

"Eeyup." Big Macintosh replied,

"What do you want?" Lightning Blaze asked,

Big Macintosh walks over to the log stump in front of Lightning Blaze and places his right front leg on it,

"Ah challenge ya to a hoof wrestle." he replied,

"You're joking, right?" Lightning Blaze asked, and he places his right front leg on the stump and grabs Big Macintosh's hoof,

"Any Pegasus who has gone up against me has lost." Lightning Blaze said,

"Ah ain't a Pegasus, Ah'm an earth pony." Big Macintosh replied,

"Your say, sister." Lightning Blaze said, and she looks and sees they were even,

"Ready." she said, and they tighten their grips,

"Go!" Rainbow Dash said, and the two hoof wrestle,

they were at a stalemate, Rainbow Dash was in shock again, her brother was strong enough to wrestle Big Macintosh, who wrestled against Iron Will and Bulk Biceps and won, the two keep wrestling, their hooves were not moving, they start to grunt and Lightning Blaze closes his eyes, he reopens them and had rainbow fire in them, rainbow electricity appears on Lighting Blaze and it shoots up into the sky, an explosion of rainbow colors appears around them and Rainbow Dash is shot back while she screams,

"What in tarnation is going on?" Granny Smith asked as she came over,

Rainbow Dash sees rainbow fire and electricity in front of her, Rainbow Dash's friends and their families run over to see what was going on, they look and see the rainbow flames and electricity as well, they soon disappear and see Big Macintosh and Lightning Blaze wrestling, Lightning Blaze had rainbow electricity appear all over his body, her friends gasp in shock at seeing Rainbow Dash's brother being strong enough to wrestle Big Macintosh, they realize just how strong he truly was, they keep wrestling but nopony can see who was winning due to the rainbow electricity from Lightning Blaze's hoof, the two keep wrestling and Big Macintosh focuses, he realizes that Lightning Blaze was tiring out, he places his hoof on the stump and the rainbow electricity goes away, everypony sees that Big Macintosh has won, Lightning Blaze looks on in shock,

"I lost." Lightning Blaze said,

"Doesn't feel very good, does it?" Big Macintosh asked,

"No, it doesn't." Lightning Blaze replied,

"Exactly, Ah hope ya now understand how yer sister feels." Big Macintosh said,

"What do you know about having a younger sister?" Lightning Blaze asked,

"Look at that orange earth pony with da hat and da yellow earth pony da bow in 'er mane." Big Macintosh replied, Lightning Blaze looks and sees Applejack and Apple Bloom,

"Ah'm a big brother too, Ah know exactly how it is, now apologize to yer sister." Big Macintosh said, Lightning Blaze nods and walks to Rainbow Dash,

"I'm sorry I hurt your pride, sister, I thought you would have the same genetics that I had." he said,

"Me too, but I don't." Rainbow Dash replied,

"I'm still disappointed in how little you achieved though." Lightning Blaze said,

"Hey, your sister had to work long and hard to get to where she was before you showed up." Twilight Sparkle said in a defensive tone,

"Yeah, and we helped her." Pinkie Pie replied,

"Instead of you outshining your sister, you should help her, I have a little sister too, and I don't outshine her like how you did." Shining Armor said,

"I understand, and I'm sorry about the damage I've done yesterday to your properties." Lightning Blaze said,

"Wait, that was you?!" Sweetie Belle asked with shock,

"I told you he's scary." Scootaloo replied,

"I was very excited about having a biological sibling so I could participate in the Sisterhooves Social, but after seeing how unfairly advantaged my brother is, and my own injury, I guess we have to sit out." Rainbow Dash said,

"It's okay, darling, we'll let you in when you recover." Rarity replied,

"Yeah, we'll make it up to ya, sugar cube, ya can have fun watchin' us too." Applejack said, Rainbow Dash smiles, she then sees Big Macintosh walk over,

"Thank you, Big Mac." Rainbow Dash said,

"Ya're welcome." Big Macintosh replied,

he grunts a little, his right front hoof was exhausted, Applejack chuckled

"It seems Big Mac might need to rest after that wrestle." Applejack said, the others chuckle,

"Hey, sister, do you still have the root beer?" Lightning Blaze asked,

"Sure do." Rainbow Dash replied,

"Let's drink it while we watch." Lightning Blaze said,

Rainbow Dash nods excitedly and they fly to her home, they see Lightning Blaze do the sonic rainboom as soon as he flew, much to their surprises.

Rainbow Dash, Lightning Blaze, and Scootaloo sit together and drink root beer while their friends and families perform in the Sisterhooves Social, there was enough for them all after they finished, they drink the root beer and agreed it was better than the cider,

"Whoo-wee, looks like we got some competition, y'all." Applejack said, they all laugh and enjoy the rest of the day together.
