The New 52 universe does not have a "Diana Prince" identity as stated in an interview by series writer Brian Azzarello. However, when she and Superman began dating, for her civilian identity she used the Diana Prince alias whenever she was around Clark Kent; such as when she introduced herself to Lois Lane at Lois's housewarming party under that name.
Princess Diana commands respect both as Wonder Woman and Diana Prince; her epithetical title – The Amazon Princess – illustrates the dichotomy of her character. She is a powerful, strong-willed character who does not back down from a fight or a challenge. Yet, she is a diplomat who strongly "favors the pen", and a lover of peace who would never seek to fight or escalate a conflict. She's simultaneously both the most fierce and most nurturing member of the Justice League; and her political connections as a United Nations Honorary Ambassador and the ambassador of a warrior nation makes her an invaluable addition to the team. With her powerful abilities, centuries of training and experience at handling threats that range from petty crime to threats that are of a magical or supernatural nature, Diana is capable of competing with nearly any hero or villain.
On October 21, 2016, the United Nations controversially named Wonder Woman a UN Honorary Ambassador for the Empowerment of Women and Girls in a ceremony attended by Under-Secretary-General for Communications and Public Information Cristina Gallach and by actors Lynda Carter and Gal Gadot. The character was dropped from the role two months later after a petition against the appointment stated Wonder Woman was "not culturally...sensitive" and it was "alarming that the United Nations would consider using a character with an overtly sexualized image".
