Beatrice is a strong, independent and intelligent woman. She is very witty, and can think on her feet. For example, in Act 1 Scene 1, Beatrice exchanges insults with Benedick;
Is it possible disdain should die while she hath
such meet food to feed it as Signior Benedick?
Courtesy itself must convert to disdain, if you come
in her presence.
Beatrice contrasts with Hero, who is a shy, obedient and very feminine character. Beatrice challenges the role of gender, and shows that women are just as capable of being evil, intelligent and picky as men can be.
