I decided to make my own twisona just for fun since I've been seeing peoples' on instagram c: this is Stardust Dazzle! She's based around season 1 twilight sparkle and moondancer, and her design is inspired by twilight's concept art, the last unicorn, and cloudchaser! (just cause she's my favorite G4 pony haha). She's an oc, but also sort of an alternate universe AU? Very much like the spiderverse. The Mirror will have a big hand in this au haha

Stardust comes from a universe where Sunset Shimmer remains Celestia's student, so Stardust never studies under Celestia. She doesn't even get into the school of magic; her world's Rainbow Dash's sonic rainboom actually messes up her audition and she fails the entrance exam. She gets an inferiority complex over this, and often hides her cutie mark under a cloak out of embarrassment (I mean, what unicorn living in Canterlot with a talent in magic doesn't get into the school of magic?). She spends a lot of time pouring over books at the canterlot library to improve her magical power, and is usually pretty grumpy and standoffish.
In the future, she'll end up studying under Princess Luna and eventually becomes an alicorn! But for now, she's just a sour shut-in lol. She doesn't know it, but the poor thing just wants some friends.

if you're wondering how she manages to get Luna's attention while not even attending the school of magic.... we'll just say that Stardust's negative emotions take control of her and something happens, wink wink.

also, there is a main 6 in her future, they just don't meet until much later compared to the show's canon. and they have their own unique elements of harmony (that will be called something different once I think of them lol), that aren't focused on friendship, but rather the self (self-care, self-improvement, that sort of thing). Stardust's is Aspiration c:
