I'm aware Applejack's proper name spelling should be as I just wrote it. But to me it just looks...unfinished that way. So I always spell it AppleJack or Apple Jack, which I can only imagine grates on the nerves of some of her fans
But I can't help it, it just looks so much better to me that way! Same with my favorite G4 male pony, Thunderlane. Doesn't it just look silly like that? So I always spell it Thunder Lane.
What about you? Any purposeful spelling changes for pony names?
