Rainbow Dash - very proud mother of 4 pegasus children - intensely in love with her wife - Captain of the Wonderbolts - avid fantasy reader, but she'll deny that - kind of a shorty - sometimes an impulsive mess - big heart though, values loyalty
Clear Sky - another proud mother of 4 pegasus children - deeply in love with her wife but she's less dramatic about it - loves a good red wine - empath, extremely in tune with the emotions of others - veryyyyy observant literally nothing slips past her - prettiest unicorn alive (according to Dash) - studied journalism but is the active manager of the Wonderbolts
Wind Sprint - famous streamer, goes by the screen name SniperKing40 - even bigger RBF than Greywind's - takes credit for setting up Dash and Sky (they reconnected because of Wind's interest in Wonderbolt training) - huge mood swings and very opinionated - does not care for a moment what you think of her - also kind of brash and rude, but she's working on it - talented flier, member of the Wonderbolts B Team - although she loves flying, she pursues her love of gameplay (and she's successful in that career path)
Thunderbird - hot mess - arrogant and a little too overly confident - also a member of the Wonderbolts B Team, he and Wind Sprint work together sometimes - claims to be the superior twin but he would die for Greywind - secretly loves to visit Aunt Fluttershy and care for the animals at her shelter - poofs his hair all by himself, every morning - huge showoff - despite his personality he's actually very physically gentle, especially around his family and Fluttershy's animals - followed Dash's legacy and became the champion flier in the family - a poser
Greywind - the chill twin - legally blind - still lives at home with Dash and Sky, and they don't know what they'd do without her - really good listener - the only kid who inherited Dash's signature rainbow mane - always slouching, but she's actually taller than Thunderbird - partakes in lots of community service - works part-time at The Cakes' bakery - very popular around town because of how genuinely sweet she is
Astra - the runt of the family - just wait till she hits her growth spurt though, she'll be the tallest in the family eventually - nicknamed Azzy - has monochromia just like her older twin siblings - inherits Rainbow Dash's elbow tufts - veryyyyy spoiled but she's humble about it - probably the youngest Equestrian citizen to get a tattoo - looks up to big bro Thunderbird
extras - as a family, they're super functional and really healthy. they all rely on each other in a way that's not too clingy, but not too distant either. - all of the kids end up leaving the house to pursue their dreams, other than Greywind, who desires nothing more than to be with her family. - Clear and Rainbow Dash wouldn't be able to part with Greywind anyway, since they're so used to having her around. - Clear and Dash both happen to have fangs, so the entire family inherited these very pronounced fangs - Astra has the biggest fangs relative to her skull size. she'll be reallllll big one day and no one's ready for it - Wind Sprint was much closer to her father than she was Clear Sky, but over years of reconnection, she develops a better relationship with her mom. and ultimately, once Dash comes into the picture, she allows herself to accept Rainbow as family. - Wind doesn't even consider her siblings "half" siblings, they're just blood to her, and she loves them all dearly - it's just chance that none of Clear Sky's children ended up being unicorns. she's half pegasus herself, which may have changed the probability - Clear does get kinda tired of finding her wife's and children's feathers all over the place tho - Thunderbird used to be pretty insecure about his duller coloration in such a colorful family (also, dull coloration isn't considered attractive among pegasi), but eventually he comes to realize it kinda makes him unique.
