I had a few ideas for alicorn Rarity, and all of them involved the living pony incarnation of bling. Oddly enough, I actually started thinking about this AU because I wanted to redesign Nightmare Rarity. I didn’t quite like the original, and I wanted to try a different angle. I’m considering making Nightmare-Rare a canon thing to this AU, though I still need to figure out how to work it in. I might draw that version of her if enough people are interested. Let me know if you’d like to see it. :D
Surprisingly, I also have a fairly well developed concept for how she ascends, too. I’m planning on saving the details for later, but it involves kicking king Sombra’s ass. I firmly believe that Rarity is perfectly capable of being a total boss bitch when the chips are down.
