Renée is one of the three titular deuteragonists of Barbie and the Three Musketeers (alongside Aramina and Viveca). She and her best friends are the girls that Corinne D'Artagnan accidentally offends and later befriends. Young violinist Renée came to Paris to become a female Musketeer, a dream that her and her friends shared but were never aware of. They become Part of a plot that could put the prince at risk before he turns eighteen.
Her name is based off of Aramis's real name René d'Herblay, but her personality seems to be more based off of Athos due to her being the de facto leader of the group.
