This is a reboot of My Little Pony: Friendship is Magic: Equestria Girls and the original show, but unlike the original series, it adds a darker tone & more action, but with humor.
In the kingdom of Equestria, its three subspecies of ponies (often described as "tribes" or "races")—earth ponies, pegasi, and unicorns—live harmoniously. Tara Spencer, a studious unicorn (later an alicorn), travels to Ponyville to learn about friendship at the urging of Equestria's ruler (and her mentor) Celeste Ryan. Tara and Spike, her dragon assistant, become close friends with five other ponies: Amelia Jennings, Raquel Beattie, Faith Summers, Roxanne Douglas, and Paulina Parker. The ponies discover that they represent different facets of friendship, with powerful magical artifacts known as Elements of Harmony.
