While Shakespeare purposefully does not attribute any truly unique characteristics to Hermia's personality nor any of the other related characters in this aspect of the play, there are a few personality traits that can be identified. First of all, she is bold and blunt and willing to rebel against her father's wishes in order to be with the man she loves. Her pent up frustrations over having a father who is stubborn and unwilling to acknowledge her own wants and needs may have lead her to develop this strong, rebellious personality. Hermia is not afraid to speak her mind, even to Lysander who is to be her husband. She tells him straightforwardly that she does not wish to lie near him in the woods in order to remain virtuous and pure until their wedding night.
Based on Hermia's behavior throughout the play, one may develop the idea that she is haughty and perhaps even a little spoiled. She wants things to go her way and she will do whatever it takes to ensure that they do. Hermia's "complex" may be that she believes she is entitled to what she wants or that she is rebelling against a paternal figure who has suppressed her desires and has led her to fight harder for what she wants.
