Highschooler Matthew Dashel, simply known as Matt, and his friends Terrance, Rina, and Harry would go to school everyday with John Radderson and Kurt Smith. They still go, despite the fact that John and Kurt were both turned into anthropomorphic versions of cartoon ponies. Twilight and Applejack, respectively. So they went to school, received a couple of weird looks, got called into the principal's office, collected a shark's tooth, confront a bully and somehow not get a visit from a government agency. To his knowledge anyway. Needless to say that Matt had a crazy last couple of days.
And it was about to get crazier.
Matt had just got home and was ready to unwind from the day's events by taking a nice long shower and going on his computer. But first a snack was needed. So he headed towards the pantry for a nice bag of generic chips. As he opened the door and started looking around he couldn't seem to find it. So he did what any sane person his age would do, ask his mother.
“Mom, I can't find the chips,” he said calling for her. “Mom?”
No reply.
“Hmm, maybe she's out buying more chips. Yeah, that's it.” He said to himself. More to reassure himself than anything. “But still she would've left a note…should probably check for that.”
After spending a half-hour searching for the note left by his mother with no results, he decided to give up and wait for her return and ask her where she's been. she's fine. She's got to be...right? he thought to himself. Sighing to himself he went upstairs to his room and turned on his computer. Checking his email he saw to messages waiting for him. One from his mom (which he was relieved to see) and one from an unnamed user. Clicking on the email, a blue glow started to come from the screen, temporarily blinding Matt and forcing him to cover his eyes with his hands to prevent himself from going permanently blind.
After the light level went back to a tolerable amount, he opened his eyes to see a picture of a cloud with a lighting bolt colored rainbow on his screen.
“That was weird…” Matt said with a hint of suspicion as he closed the email “Whatever it was, it's done now.”
Little did Matt know, a set of changes was happening across his body. Starting with blue hairs growing on his legs. Slowly creeping up his entire body. But to Matt it just felt like a small itch around his ankles.
Regardless, he proceeded to gather the things necessary for a shower. After getting the required clothing (a white tank top, underwear, and a pair of black sweatpants) and a towel, he stepped into his bathroom. But before he could even finish removing his pants, he noticed that both of his legs was covered in a cyan blue fur. Thinking he's just seeing things, Matt did a double take just to be sure.
“Yup, that's fur alright,” he said with a suspicious tone. The fur looked and felt real, as if it belonged to some unknown animal.
The strange symbol from the computer, a white cloud with a rainbow lightning bolt appeared on his outer thighs as if it were meant to be there. It blended into the cyan fur nicely.
“Meh, could be about 20% cooler.” Matt said, unintentionally making a reference from the episode Suited for Success, spoken by Rainbow Dash herself.
Next, his hair started getting longer and different strands of it appeared to develop into red, orange, yellow, green, blue, indigo, and violet; the traditional colors of the visible light spectrum, or rainbow. A similarly colored tail burst from his backside, swishing back and forth.
“I-i guess that's what the rainbow portion of the name means, hehe...” He nervously said, slightly startled by the tail’s sudden appearance.
As soon as Matt’s new hair and tail grew in, his face was covered in the same cyan fur as his legs. His eye color shifted to a bright magenta as his face feminized into a muzzle, his teeth shifting into that of the equine/human hybrid he was becoming. Eyelashes appeared around his big eyes.
As Matt adjusted to these new changes, his body began to take on a more athletic but feminine appearance. A pair of cyan pony ears appeared on her head, twitching in response to every sound in the room. Eventually, a pair of cyan feathered wings sprouted from his, or rather her back as the final changes left Matt standing in the bathroom covered in cyan fur, complete with back hooves for feet. When she looked at the bathroom mirror, the reflection of the new
anthropomorphic Rainbow Dash stared back at her. When she tried to talk or breathe, the new voice sounded higher pitched and with a natural rasp.
“Oh my...this is so awesome!” Rainbow Dash flapped her new wings experimentally as she admired her new rainbow mane in the mirror.
Eventually, the new Rainbow Dash wanted to show her new look to her friends, so she texted Ashley and told her to meet her at school, with the explanation that "something awesome" just happened.
Ashley got the text from an excited Matt, claiming something "awesome" just happened and wanted to show something to Twilight and the rest of the close friends at school. "Ya think that this "something awesome" has to do with us becomin' the anthro versions of the Elements o' Harmony bearers, Twi?"
Twilight nodded, "Sounds like Matt has become Rainbow Dash. Just like I predicted. Rina's definetly going to become Pinkie Pie, Terrance will be Fluttershy, and Harry will become Rarity."
