Hi! This is my first rewrite of the main six because I'm 17 now and I don't like them like I did when I was 11.
This is Twilight Sparkle who is now a trans stallion. His parents were famous musicians and thus he lived in Canterlot and was able to go to Celestia's school.
He did not change his name when he transitioned because he felt it wasn't masculine enough, he changed it because it's music-themed and he would rather have pursued music and have a name to match.
He's kind of the pessimist of the friend group and is the first to cancel on going out and oftentimes shuts himself in for weeks. They don't mind, because they know how he is, but it has left him unable to make friends in the past.
His burst of magic that earned him his unicorn also lead to the injury on his face, because there's no way he suddenly used that much power at such a young age controllably and nobody got hurt?
He doesn't become an alicorn, because I always felt like that was stupid. Sorry. He remains a unicorn and retains his original personality, because you should not have to change as a person to have friends, unless you're actually an asshole.
He is Celestia's student, though.

You can draw this design but please credit me for it.
