Lady Bane was a wicked witch from Disney's Gummi Bears who was both a villain in her own right as well as an on-and-off "ally" with Duke Sigmund Igthorn (Duke Sigmund was madly in love with her, a feeling she did not share).

Lady Bane was power hungry, cruel and generally what one would expect from a fairy tale witch - she was also in reality a crone whose youth was kept via black magic (as seen in one episode where she stole Sunni's youth in order to transform herself into an attractive sorceress).
