Dark things can change a Pony
I don't know how the age system works in My Little Pony, so it will work like the human age system, besides they anthro human bodies in this story, but they don't show any traits of pony.
But I'll refer them as
Colt(s): For males when they are children or a teens
Stallion(s): For males when they are adults
Filly(s): For females when they children
Mare(s): For females when they are teens or adults
And I refer more than one person: pony, everypony, somepony, ect.
Here is what they look with anthro bodies
Earth Ponies: They look like regular humans, but like in the show, they have super strength and great stamina.
Unicorns: They look like humans with a horn sticking out of their foreheads.
Pegasus: They look like humans with wings.
Their cutie marks are shown on each side of their arm. Even though they look like humans, they don't meat, they eat normal like in the show, they eat grass, flowers, fruits, and sweets.
And like humans, they wear clothes, just so you know. You readers can imagine what clothes they wear.
Rumble has the best life he ever has. He's one of the best athlete in the school of Cheerilee's, he caught the eyes of many females because of that, but that actually annoyed him. Many fillies would ask him if they want to hang out, every Valentines ( Hearts and Hooves Day ) he would come home with a backpack full of cards and chocolates, he was annoyed with the cards, but not the chocolate. Other than that, he has a nice life, he has some great friends, two great foal sitters, one great older brother, and he had two great parents.
That's right, he had parents, the two died when he was young. They died at work when the cloud machine maker went haywire and exploded. Many survived, only those two didn't make it. Rumble got the bad news from Thunderlane when he came back home from school, he took it really hard. He isolated himself from his friends, his foal sitters, and everyone else in Ponyville including his brother.
The only bright side to this is that Rumble became more athletic because he started doing martial arts and do a lot of exercise to clear his head. Fillies became more interested him, but he became rude to them to make them leave him alone and he didn't care if he hurt their feelings.
Seeing his young brother not taking it so well, Thunderlane decided to move from Ponyville to Las Pegasus. Cloudchaser and Flitter decided to also move with them to help with the Rumble situation.
But it didn't work, when they move to Trottingham, Rumble didn't change back to his old self.
At the age of 16, Rumble move out from his brother's and move to his own. He got the money to move out because he became an assistant of a martial arts master to help teach other martial artists. Thanks to all the training and fighting, he finally gained a cutie mark, a black tornado with lightning striking into it, it means he has powerful fast speed and strength.
His routine now ever since he move out would be waking up really early before morning, go exercise, go to school, go to work, come back home and the cycle will restart itself.
But that changed when he got a letter from Ponyville after coming back home.
Dear Rumble,
Your invited to come to my wedding in Sweet Apple Acres, which will be in a about two months
I'm getting married to Big Macintosh Apple.
I hope you come, I missed you and my other students who used to go to my school.
Speaking of which, I'm having a little get together with them, I really hope you come because everyone else misses you.
From your favorite teacher,
Cheerilee Smiles, soon to be Cheerilee Apple.
Rumble look at the letter after he was done reading, he's choosing to go or not. He want to see his old teacher in Ponyville, she was the only one he act around his old self because she is like a second mother to Rumble. But he seriously didn't want to go back to Ponyville, bad memories of the incident. But he also didn't want to hurt his favorite teacher's feelings.
He put the letter down, he took out a briefcase from under his bed and started packing some clothes and other stuff needs. He's going to the wedding.

When Rumble was done packing, he went to the dojo he works in. When he got there, there is only one earth pony there. It was the master of the dojo, Will Power.
"Rumble, why are you back so soon? Class is already over." Will Power said when he saw him, he then saw his luggage. " What's going on ? "
He answered his master by giving him the invite.
" I see, " Will Power said when was done reading the wedding invitation. " so are you going ? "
" Yes, I'm going, " Rumble said. " I hope you let me take a couple of month off to go. "
" Rumble," Will Power began with a smile. " you have been helping me teach class ever since you came to my dojo, you deserve a break. "
The dark and light grey Pegasus bow. " Thank you master. " He said then starts to leave.
" Good luck Rumble. " Will said as he watch his assistant flew away at a fast speed.
Ever since Rumble started to exercise a lot more often, he became really fast at flying, his speed could rival Rainbow Dash's speed or maybe he's faster than her now. He didn't need to take a train to go from Trottingham to Ponyville.
Usually it would take about a week to go to Ponyville from Trottingham, but Rumble can go to Ponyville in less than week without a break, he did it before a couple of times. The only reason he go to Ponyville was to respect to his dead parents, they were buried in Ponyville Cemetery, no ones knows Rumble was there a couple of times.
* 3 days later *
Rumble is now in front of Ponyville, he knows everypony pretty well there, and he remembers pretty well that a certain pink earth pony would make a big party for someone who is new to Ponyville or someone returns to Ponyville after a long time or other excuses to have a party.
He didn't came out in broad daylight, he sneak behind Daisy, who changed a little over the years and also selling bouquet of flowers, he took two of the them and leave some bits to pay for them.
Daisy was startled when she heard some bits hit her stand. She found two bouquet gone and no one in sight with one.
" That's the 4th time that happened. " Daisy thought with some fear. " Why's that keep happening every year. "
Rumble sneak around Ponyville to the cemetary, he flew over to two tombstones that were side by side. The first one said Windy Lane and the other one said Gentle Breeze. He put a bouquet of flowers on each of them.
He put down his luggage, went to his knees and started to pray.

After Rumble was done praying, he pick up his luggage and started walking to a familiar place that he hadn't been there for a long time, Cheerilee's school. His watch says 4:18 PM, he remembered correctly that school usually ends at 3:30, but the schedule could change over the years. But he wanted to see his favorite teacher first after so long.
When he reached his destination, he didn't see fillies and colts outside the school house and didn't hear any from the inside, so it was assume school is over, but he hope Cheerilee is still inside. Rumble walk up the front and when he was so close to it, the door open from the inside, from a pegasus mare who was in some kind of hurry.
"Bye Cheerilee, see you at the par-!" The pony yell partially because she flew out of the school so fast, she bump into Rumble, making them both crash to the ground, with Rumble under the mystery mare.
The first thing Rumble saw after the crash was something orange and purple. He knows he knew this mare before, but thanks to the collision, he can't think much of who it is. He got an answer when another mare, this time entirely purple, came out of the school house,
"Scootaloo, are you Okay!?" Cried the purple mare with a worried voice.
"Scootaloo, oh yeah now I remember," Rumble thought, then realization hit him like a ton of bricks, he was under a mare he knew very much.
Scootaloo stand up to her knees while rubbing her head."Yeah, I'm fine Cheerilee, I just hit this damn colt."She said with an annoyed voice.
Cheerilee look at the colt who was under Scootaloo and was shock to see who it was."Scootaloo, you might want to look closely at the colt."She suggested.
Scootaloo wonder why and look at the colt, and boy was her shock face was priceless."RUMBLE!?"
"Hey Scootaloo,"Rumble greeted."no need to yell."He criticize rudely.
Scootaloo's eyes narrowed at him and crosses her arms."I can see you haven't change since."
"Scootaloo behave."Cheerilee said as she pick up one of Rumble's luggage while the two Pegasi got up from the ground.
Rumble look at Scootaloo, he saw that she has changed a lot over the years, she was about 4 inches shorter than him ,her hair is long and wild and she finally have her cutie mark, it was a wheel of a scooter with a pair wings sprouting from the sides
The purple teacher give Rumble his luggage after he dusted off dust of him."Thank you Ms. Cheerilee."Rumble said kindly to her.
Cheerilee giggle."Just 'Cheerilee',okay Rumble?"She said then gave him a big crushing hug."I can't believe you actually came."
"Well I didn't want to turn down your invitation, plus I haven't seen you after so long." Rumble said to her as he return the hug.
Cheerilee let go of him and got a good look at him."Maybe too long."She suggested."Look at your self, your almost tall as Big Mac and he's older than you."
Rumble chuckled, showing some of his old self to her."Speaking of which, congratulations of your marriage."
"Why thank you Rumble."Cheerilee said."So where are you staying until the wedding is over?"She asked.
"I got enough bits to stay at a hotel until then."Rumble replied.
"Are you sure?" Cheerilee asked with worry."I mean the Apple family have a guest room,you can stay there until then."She suggested to grey Pegasus.
"Thank you for the offer, but I don't want to be a bother."He said.
"Okay Rumble,but if you need anything, me and the Apple family will be here for you."She said with worry in her voice.
Rumble nob."So when is the get together?"
"Tomorrow,you see there."Cheerilee replied.
Rumble nob and starts to leave,until a certain orange Pegasus block his path."What do you want Scootaloo?"
"I thought I'd show around town,"She replied."a lot of things had change since you moved away."
"I can take care of myself." Rumble said as he pass her, but Scootaloo started to follow him.
"If you don't let me,I'll tell everypony that your back."She threatened
Rumble stop and sigh."Fine."He said as he open one of his luggage.
"What are you doing?"Scootaloo asked.
The grey Pegasus didn't answer yet, he put on a face mask that covers his mouth and nose."I don't want to be known just yet until the get together and other reasons."He replied.
"Let me guess,"Scootaloo started.
"Pinkie Pie."The two Pegasi both said unison, that got Scootaloo to giggle and Rumble to smile a little, but she didn't see it thanks to the face mask.
Scootaloo took her scooter, which is a big new one that is connected to a wagon, by the fence, she jump on .
"Hope on."She said to Rumble.
Rumble put his luggage on the wagon, he went to the back of Scootaloo and hold on tight onto her as Scootaloo rapidly flap her wings that instantly propel them at a fast speed.
"So where you want to see first?"Scootaloo asked
"I haven't eaten since I came here,"Rumble replied."let's go see how Sugar Cube Corner doing."
The Sugar Cube Corner hasn't change a bit over the years.
When they got inside the famous bakery of Ponyville, they were greeted by a hyper active pinkie earth pony.
"Hey Scootaloo, are you ready for the party at Sweet Apple Acres tommorow?"Pinkie Pie asked as she saw the organge pegasus, then she turn her attention to a pegasus she never saw before and began to ask a ton of questions
"A new pony in town ! I can tell that your new here because I know everyone here.So where are you from?When's your birthday?And what's your name,so I can present you to the party I'm going to host for you?
Scootaloo was going to stop her, but didn't have the chance to.
"Oh wait,"Pinkie said."Let me guess."She started looking at him very closely." Masquerade?Silent Black?Cool Mask?"
"PINKIE!!!"Scootaloo scream to get the hyper pink pony's attention.
"Yes Scoots?"Pinkie asked, not mad of being yelled at.
"Pinkie,he's not new here."Scootaloo said.
"Then how come I've never seen him before?"Pinkie asked.
"Because he lived here before, he's just visiting here for a couple of months."Scootaloo replied.
"Oh,"Pinkie said."then I'm not going to give you a 'Welcome to Ponyville Party',instead I'm going to give you a 'Welcome Back to Ponyville Party!!!!"She screamed at the last part.
Rumble knew this would happen, but ignored it."I'll have a cupcake."He said as he hand out a bit.
"Okey dokey lokey."She said as she took the bit and give him a cupcake.
"By the way,"Rumble began."I don't want a party."
"What !?"Pinkie exclaimed in surprise."Why not?"
"Because if you give me a party,"Rumble began."I will not be your friend."He threaten.
Pinkie have a sad face on, but quickly disappears with a smile replacing it."Okey dokey lokey."She said happily as she have gave Rumble a hug."I got a new friends, that's all that counts."She exclaim in happiness.
Rumble rolled his eyes when he got out of the hug and left the bakery.
Scootaloo glared at him, but not much."Did you have to do that?"
"I came here for the wedding, not to hang out with old friends."Rumble answered as he started eating his cupcake.
