Madeleine Waverly, also referred to as Baroness Magdalene Waverly in various materials, is a supporting antagonist in the anime Lady Lady!!. She is the aunt of the Russell sisters, Lynn and Sarah, and the mother of Thomas and Mary Waverly. A scheming noblewoman, she arrives at the Marble Mansion shortly after Lynn’s arrival in England and announces her intention to marry Lynn’s father, Viscount George Russell, thereby becoming the girls’ stepmother. Her primary motivation is financial and social advancement; she seeks to secure the Russell fortune and elevate her own status. Madeleine is cold, manipulative, and often cruel, particularly toward Lynn and Sarah. She shows little warmth or genuine care, treating the girls as obstacles to her plans. While the Viscount is away, she takes over the household and imposes strict, unpleasant rules, frequently siding with her own children’s mischief. Despite her antagonistic role, she occasionally reveals a pragmatic rather than purely malicious nature, focused on maintaining appearances and control. Her key relationships are with her children, Thomas and Mary, whom she indulges, and with the Russell family, whom she attempts to dominate. She does not undergo significant positive development over the course of the story, remaining a persistent source of conflict for the protagonists. Her notable abilities lie in social manipulation, cunning, and her capacity to wield authority within the household when the Viscount is absent.
