Oh Applejack, you're really the only G1 pony that has survived as much as possible.
Anyway, yes this is G1 Applejack. She used to wear no hat and had some more apples than what she currently has on her cutie mark. She was the pony who went on travels with the other human who I believe is called Meghan.
More G1 ponies coming soon! Don't forget to follow me on Tumblr [link]
