Regina Mills

Regina Mills is the former mayor of Storybrooke and, prior to that, preceded Snow White as the Queen of the Enchanted Forest. After the murder of her fiance and being forced to marry Snow White's father, she took most of her hatred out on her new stepdaughter, allowing her pain to darken her and earning herself her reputation as 'the Evil Queen'. She, like most of the characters from the Once Upon a Time fandom, did not arrive on AM through a rift - instead, she was responsible for the curse that brought the inhabitants of her land here, wiped their memories, and held them in stasis for twenty-eight years.
