Olivia Flaversham is a supporting protagonist in the Disney animated movie The Great Mouse Detective. The daughter of the toy-maker Hiram Flaversham, Olivia is a young girl who dearly loves her father. It was with her help that Basil of Baker Street foiled Ratigan's latest scheme, after the evil professor kidnapped her father as part of a plot to take control of the mouse kingdom. Olivia is featured in the events of Heroes vs. Villains, though not seen with her father, comforting Fievel Mousekewitz after the mouse got separated from his family. She also appears in the second Disney Heroes vs Villains in a similar role to the one of the movie, though here her father is kidnapped by Fat Cat instead of Ratigan.
