I know there's already a thread like this, but I'm too lazy to find it and point it out. Lightning Dust Cadance is best princess.
Definetely Luna. I mean, Celestia's okay, and Cadence's eh. And Twilight? She's always gonna be a Unicorn to me.
My thoughts exactly. Tho, too bad we almost never see Luna for more than 5 minutes in an episode. Well, except for her episode.
Luna, she is the one with with the most personality,or should i say ponyality. And what's cooler than looking into people's dreams.
