Twilight Sparkle

Twilight Sparkle is a unicorn/alicorn and one of the main characters of My Little Pony: Friendship is Magic, and appears as one of the main protagonists in My Little Pony: The Movie.

Role in the Movie
In the film, Twilight organizes the Festival of Friendship in Canterlot. When the city is invaded by the Storm King's forces, led by Tempest Shadow (also known as Fizzlepop Berrytwist), Twilight and her friends escape to seek out the "Queen of the Hippos"—later specified to be Queen Novo of the Hippogriffs—for help, as per Celestia (or not Celestia), but the instructions. During their journey, they are nearly sold into slavery by Capper and thrown overboard Captain Celaeno's airship. When they find Novo in Seaquestria and she refuses to help save their home, Twilight resorts to attempting to steal her Pearl of Transformation, resulting in her and her friends' banishment from Seaquestria when she gets caught.

After a heated falling-out with her friends, Twilight, while she is sad and crying like a baby or whatnot, is captured by Tempest and brought back to Canterlot, where the Storm King uses the Staff of Sacanas to drain her and the other princesses' magic. Twilight saves Tempest from being swept up by the Storm King's tornado when he betrays her, and Twilight's friends arrive to rescue her and liberate Canterlot. Twilight and her friends eventually succeed in defeating the Storm King, and she restores Tempest with the staff after she sacrifices herself to save them from his final attack. In the end, Canterlot is restored, the Friendship Festival resumes, and Twilight and her friends befriend Tempest
