We should note that not many of the ponies on this page have been named within the show (and even those that have been named have mostly only been named once in conversation, so it's unknown if their in-show names are their full and/or real names). You'll notice most of the characters listed here have been front and center of the camera at least once.
'Background pony' is a somewhat misleading term (they're called incidental characters by the show's staff), its more of a catch-all term used by the fanbase to refer to all the show's Recurring Extras and One-Scene Wonder ponies that aren't really a part of the Supporting Cast (like Big Macintosh and Zecora). Below are listed the most popular background ponies. Whatever the reason, the fans can't get enough of them. Perhaps it's the unique art style that gives them a little more personality, or the memorable gag scenes they feature in. Seriously these mostly nameless extras are pretty much why My Little Pony: Friendship Is Magic has its own Ensemble Darkhorse page.
