Many writers have depicted Diana in different personalities and tone; between both of her diametric extremes; that of a worldly warrior, a highly compassionate and calm ambassador, and sometimes also as a naive and innocent person, depending on the writer. What has remained constant, and is a mainstay of the character, is her nurturing humanity: her overwhelming belief in love, empathy, compassion, and having a strong conscience. This trait had been the reason for her induction into the Star Sapphires.
Wonder Woman’s powers are a result of the blessings she received from the gods (or presumably in the modern version by her divine ancestry), but originally came from her "brain energy" training. Her abilities in large part come from her upbringing in the martial society of the Amazons. She is one of the most powerful superheroes in the DC universe.
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.
The American theme of Diana's costume was explained by Pérez in the Challenge of the Gods storyline in which Diana engaged in a series of trials arranged by Zeus as punishment for refusing his advances. Diana met the spirit of Steve Trevor's mother, Diana Trevor, who was clad in armor identical to her own. Trevor revealed that during World War II she had crashed on Themyscira while on duty as a U.S. Army pilot. She blundered into an Amazon battle against Cottus, a multi-armed demon, at the portal to the underworld. Trevor was drawn into the battle, although she was armed only with her side arm. She wounded the beast before suffering a mortal blow, allowing the Amazons to reseal the portal.
Who are the Dark Gods, and what is it they want? We don't actually see them in the issue; the only glimpse we have of them so far is on the cover. They look mighty and regal, and they certainly look dangerous. We don't yet know where exactly they come from, but the issue's advanced solicit description does confirm that they have arrived in the wake of Dark Nights: Metal, and that they are part of new secrets of the cosmos -- secrets that have just been unveiled. Already, we have seen that they are able to affect the minds of the masses, and turn them against their own kind. And this is only the start.
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".
The Diana Prince alias also played an important role after the events of Infinite Crisis. Wonder Woman was broadcast worldwide killing a villain named Maxwell Lord, as he was mind controlling Superman into killing Batman. When Wonder Woman caught him in her lasso, demanding to know how to stop Superman, Maxwell revealed that the only way to stop him was to kill Lord, so as a last resort Diana snapped his neck. To recover from the trauma of killing another person, the Amazon went into a self-imposed exile for one year. On her return to public life, Diana realized that her life as a full-time celebrity superhero and ambassador had kept her removed from humanity. Because of this she assumed the persona of Diana Prince and became an agent at the Department of Metahuman Affairs. During a later battle with the witch Circe, a spell was placed on Diana leaving her powerless when not in the guise of Wonder Woman.
