The Dash-Soarin Kids
Dash and Soarin always had a crush on each other, but when Rainbow made it to the Wonderbolts, they finally began going on flights together. Then, despite Rainbow's hesitation (she isn't into sappy stuff), they went out a couple times to a fancy restaurant in Canterlot. After a couple years, they got married, both of them performing for the crowd with their Wonderbolt friends. Pinkie cried the whole time, and even Fluttershy got teary-eyed. Applejack just cried on the inside.
NOTE: I redid Spectrum
Spectrum:
Age: 12
Gender: Female
Bio:
Spectrum was the first twin to be born and teases her sister about it like crazy. She didn't fly as soon as her twin but she caught up to he rand they progressed through the levels together. When Spectrum met Livia (it wasn't the first time because their mothers often got together. They just weren't really friends), it was at a Parkour competition. Livia beat her so bad that Spectrum went over immediately after the race and asked the dragonet/filly to teach her. Livia happily agreed and taught the twins several moves. When her sister reformed parkour for the air, Spectrum took it up quickly. She was a fast flier already and soon became quite an aerial acrobat.
At school, Spectrum is BY FAR a popular filly. She loves making new friends (even if they aren't very nice to her sister), and spends almost zero of her school day with here sister, even flying home. Wherever she goes she has friends, may it be a store, school, or Cloudsdale.
Sectrum is very open, nice, gentle, and a little bit girly. She loves watching Dusk for Twilight, helping Aunt Fluttershy with all the animals, and even likes to do her hair every now and then. Despite all this, she is very competitive. Once she gets in a race, she puts everything into it.
Prism:
Age: 12
Gender: Female
Bio:
Whenever her sister teases her about being born first, Prism gets a little worked up. She doesn't mind at all that she's younger, just that her sister keeps teasing her about it! If Prism has to clean a particularly hard room and Spectrum gets an easier one, Spectrum will giggle and say "It's because I was born first." Prism is not as close to her sister as everypony thinks she is. She's rather distant, in fact. Prism was at the same race where Spectrum met Livia. All three became friends, but Spectrum wasn't as close a friend to the filly/dragonet as Prism was. Prism got her cutie mark a few months later when she began converting ground parkour moves into air parkour moves. She is slightly better than her sister at air stunts, partly because she made most of them up.
Because Prism is very introverted but very competitive, most ponies think she's mean or cranky. At school, she's picked on by Spectrum's friends, and Spectrum even takes part in some of the teasing, although she would never purposefully harm her sister (she just thinks that it's funny teasing (NO, SPECTRUM ISN'T STUPID)). Although she had a couple other friends, Prism mainly hangs out with Livia, and the two will sometimes pick a random course (say, through the woods or the town) and Livia will run below while Prism flies above, or they'll both run along the rooftops or the tree branches.
Prism is very introverted, has a short temper when it comes to Spectrum, is very gentle, and, when she's alone or with Livia, she talks (When she's a lone talking to herself she doesn't do it loudly). If she's not with Livia, she likes to be alone, and will go on long flights by herself, exploring the nooks and crannies around Ponyville and Cloudsdale. At Cloudsdale, she even found a small cluster of poofy, fluffy clouds, When the sun sets, they fill with light and look like they're on fire!
