Margo Gru

Margo Gru, or simply Margo, is the eldest adopted daughter of Lucy Wilde and Felonius Gru in the Despicable Me franchise. She appears in all four films and several mini movies. Before being adopted, Margo was an orphan who, like her younger sisters Agnes and Edith, was mistreated by Miss Hattie. Margo disapproves of Edith's mischievous behavior, but will join in if it's directed at someone she dislikes.
