Applejack is from My Little Pony: Friendship is Magic. Her PB is Erin Chambers and her journal is BumpkinPony. Her player is Sage

Applejack is a trustworthy, loyal, truthful young lady who once had four hooves and no hands. She knows how to cook and bake up a storm, knows everything about apples ever, and is athletic. She's got a competitive nature and a down-to-earth personality, so what you see with her is what you get.

She's coming in 'round the end of season 1, not that that really changes much of anything, but y'know. Canon-pup.
