Scene Summary
At the formal, Twilight wins the election and the crown, but Sunset steals it after threatening to destroy the portal to Equestria. Upon donning the crown, Sunset transforms into a demonic creature and uses her newfound powers to brainwash much of the student body into becoming her army with which to invade Equestria. When Sunset attacks Twilight, her friends race to save her, evoking the crown's magic that protects them and temporarily gives them pony-like attributes. The magic of their friendship reverts Sunset to her human form and breaks her spell on the other students. Sunset becomes repentant, and Twilight asks her friends to look after Sunset in her absence.
