My 'ponysona' is basically me, so her name would be my name, which is Inkling. In G4, I love Rarity's name the most because I think it's the most unique, it actually describes a bit more of her personality rather than just what she does or likes (or at least it does in my mind), and it's a single word as opposed to two, which I also find more 'name-like' and appealing. So I knew I wanted my pony name to be only one word too, while still matching her overall look and my personality. I've gone by Inky-something on all my web handles for quite a long time, and I find the idea of ink really suits me well as both a writer as an artist. But I feel like Inky was a bit too cute and maybe overused, so I chose Inkling instead since I feel that says a little bit more about her personality as well, thoughtful, maybe a little mysterious, and a bit hidden away with more to her than first meets the eye. Maybe that's giving myself too much credit since she is based after me, haha, but mostly I like how it portrays her/me as not quite "finished" yet.
