Scraton 
What pony first comes to your mind when MLP is mentioned? 
Moonbow@Scraton princess Luna or twilight sparkle
Elusive Purple 
@Scraton Fluttershy, on instinct. I think it makes sense, because the person who introduced me to G4 was a huge Flutters enjoyer 
Sophie 
@Scraton fluttershy or sunburst (fluttershy because kin :p)
Onyx Deadshot 
@Scraton King Sombra/Mirror World King Sombra as they are my favorites.
kimoradraws@Scraton Horses. A lot of pastel colored horses.
Edit: I do really mean it, I think of a whole herd of horses. Can't put my mind on a single horse.
Clearwater
eons Luna (Eonity)
Laura Orchid@Scraton Twilight
Jamis 🔜 Czequestria@Scraton Twilight Sparkle. Although Fluttershy is closer to my heart.
