This is Applejack of My Little Pony: Equestria Girls and Rainbow Rocks captured and bound as a bunny girl.
Applejack is a character from the My Little Pony franchise and one of the main characters in My Little Pony: Friendship is Magic who is set to appear in Equestria Girls 1&2 as the tritagonist. She represents the Element of Honesty.
Applejack, like her pony counterpart, is pretty strong. It is apparent during the song Time to Come Together that while two boys struggle to pick up a table, Applejack was able to carry a table with one arm at ease.
Applejack is related to Granny Smith, Apple Bloom, and Big McIntosh.
Rainbow Dash once offered to come to Applejack’s bake sale and bring the whole softball team with her. Applejack told the whole school that Rainbow and her team would attend, but since none of them showed up, it made Applejack look like a liar. Little did Applejack know that Sunset Shimmer texted Rainbow Dash saying that the event was planned at different time, Sunset signed Applejack’s name to the text instead of her own intentionally. Later in the movie they figure out what had happened and become friends again. She tends to hang out with Rainbow Dash more.
