Okay… So… Who was the idiot that decided “Hey, wouldn’t it be great if Twilight, the pony who’s extremely magic oriented, was a pony that didn’t do magic?” Like what??? So, of course, I made her back into a Unicorn. I noticed how the tried to make each race more unique- and I like that! So I made it that Unicorns have those traditional unicorn tails, and have little cutie mark-shaped hooves. I made her hair violet and pink because Hasbro really doesn’t seem to like dark blue, plus it doesn’t look that bad, I based the hairstyle off of one of the designs that I liked. I also gave her a more “royal” muzzle since she is from Canterlot.
As for personality, I think that since they don’t want the whole “magic is commonplace” deal going on, I think Twilight is going to be an aspiring magic-scientist. Like, she studies magic and wants to understand it and be better at it, but she’s not some magic master like in G4.
