Shortly after coming to the outside world, Diana interrupted a terrorist attack and was named "Wonder Woman" by the press. She continued to use her gifts to fight for peace and justice in Man's World. She later fought who she thought to be Ares, though in truth it was Phobos and Deimos who were disguised as their father. Fearing that she would eventually discover the truth and free Ares from his prison beneath Themyscira, the Gods of Olympus sent Phobos and Deimos to erase all memory of Themyscira from Diana's mind. The twin gods were unable to erase the memory, so instead they later implanted false memories regarding her home to deceive Diana, leading to a completely separate origin story and causing her to hallucinate new adventures. Diana was unaware that her memories had been tampered with, and believed the falsifications until her search for the truth led her to Ares himself years later.
Demeter, the goddess of agriculture and fertility, blessed Diana with strength drawn from the Earth spirit Gaea, making her one of the physically strongest heroes in the DC Universe and the strongest female hero in the DC Universe. This strength has allowed her to easily overwhelm Superman and Supergirl. She has also held her own against Darkseid. Her strength has no measurable limits and she can break the Chronus Scepter, which is universal in its destructive power. However, now Diana is the daughter of Zeus, king of the Greek Gods, so it is unclear as to how much of her power and strength is a direct result of her divine heritage. Her connection to the earth allows her to heal at an accelerated rate so long as she is in contact with the planet. However, as mentioned earlier, now that she is a demigoddess, it has been suggested that she heals extremely quickly also due to her divine heritage. In rare cases where she has been gravely injured, Diana showed the ability to physically merge with the earth, causing whatever injuries or poisons to be expelled from her body; such an act is considered sacred, and can only be used in extreme cases.
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.
Both of those tales are worth reading, but the real highlight of this book is Wonder Woman #170, a story titled "She's a Wonder!" This standalone issue features an interview between Diana and Lois Lane as the two spend a day together and Lois learns a little about what it means to truly be Wonder Woman. This issue is widely regarded as one of the one of the best in Wonder Woman's long history, and it's well worth tracking it down even if you forego the rest of the book.
Diana is depicted as a masterful athlete, acrobat, fighter and strategist, trained and experienced in many ancient and modern forms of armed and unarmed combat, including exclusive Amazonian martial arts. With her godlike abilities of incalculable superhuman strength, nigh-invulnerability, speed, flight, healing factor and semi-immortality, Diana’s fighting prowess is enhanced. In some versions, her mother trained her, as Wonder Girl, for a future career as Wonder Woman. From the beginning, she is portrayed as highly skilled in using her Amazon bracelets to stop bullets and in wielding her golden lasso. Batman once called her the "best melee fighter in the world". The modern version of the character is known to use lethal force when she deems it necessary. In the New 52 continuity, her superior combat skills are the result of her Amazon training, as well as receiving further training from Ares, the God of War, himself, since as early as her childhood. The Golden Age Wonder Woman also had knowledge in psychology, as did her Amazon sisters.
