United Nations, Air Force captain and ambassador, and in the '70s TV series, Lynda Carter's Wonder Woman used Prince to serve as an agent of the Inter-Agency Defense Command. In the DC Extended Universe, Prince works as curator for the Department of Antiquities at the extremely prestigious Louvre Museum and is held in very high esteem by the curator of the Gotham City Museum of Antiquities. Her tremendously long life span, accumulation of immense amount of knowledge and exceptional perceptiveness makes Diana Prince the wisest and most emotionally-intelligent member of the Justice League. During Marston's run, Diana Prince was the name of an army nurse whom Wonder Woman met. The nurse wanted to meet with her fiancé, who was transferred to South America, but was unable to arrange for money to do so. As Wonder Woman needed a secret identity to look after Steve (who was admitted to the same army hospital in which Diana Prince worked), and because both of them looked alike, Wonder Woman gave the nurse money to go to her fiancé in exchange for the nurse's credentials and took Diana Prince as her alias. She started to work as an army nurse and later as an Air Force secretary. The identity of Diana Prince was especially prominent in a series published in the early 1970s, in which she fought crime only under the Prince alias and without her mystic powers. To support herself, she ran a mod clothing boutique. 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.

Because of this she assumed the persona of Diana Prince and became an agent at the Department of Metahuman Affairs.
