Applejack is a light orange earth pony with green eyes. She has three eyelashes on each eye that curve upward. The inside of her ears are light pink, and her fetlocks are the same color as her coat. Her mane is blonde, with a slightly curly forelock and the rest of her mane tied in a red ponytail holder. Her tail is also held in a red ponytail holder. She wears a brown cowboy hat at all times. Her cutie mark is a red apple with a green stem.
Applejack has the ability to speak to viewers directly.
In Princess Probz, she addresses the viewers and asks "Did you miss this? I miss this", referencing the fact that this is the first episode since the finale of My Little Pony: Friendship is Magic.
