The "Diana Prince" identity has been part of Wonder Woman's history since her comics debut in 1941. In the early Golden Age stories, Wonder Woman served as a military secretary during World War II, using Prince as her cover. Later occupations Wonder Woman performed as Prince included translator at the 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.
The New 52 version of the character has been portrayed to be a younger, more headstrong, loving, fierce and willful person. Brian Azzarello stated in a video interview with DC Comics that they're building a very "confident", "impulsive" and "good-hearted" character in her. He referred to her trait of feeling compassion as both her strength and weakness.
Even alongside all of her kindness, compassion, and empathy, Diana is still also a warrior at heart, and when someone she cares about is hurt, becomes far more relentless and ruthless. When seemingly beaten by Ares (who was only growing more powerful from her violence, rage, and hatred), and after having to watch her beloved Steve Trevor die, she flew into an agonizing rage, and she assaulted and brutalized several armed German soldiers with immense speed and ferocity. She even came close to murdering Dr. Poison as vengeance for Steve's death; but after recalling Steve's great love for an undying belief in her and her beliefs, restrained herself and refocused her energies on Ares, harnessing her love for Trevor to overcome her violent emotions and swiftly overpower an angered Ares. Additionally, she resolved to fight even harder after Steppenwolf revealed that he had killed several other Amazons. Outside of battle, however, Diana can also react indigently and negatively towards people who disrespect her, her relatives, or those she cares about. Two such notable instances were when she shot an angry look at Lex Luthor (after he insulted her father Zeus's memory), and when she shoved back Batman (after he had insulted her beloved Steve Trevor's memory). Diana also remains ruthless when facing enemies in battle as Wonder Woman, and she even shows signs of enjoying a good battle when they put up a good fight. This was seen when she briefly smiled and laughed when she was beaten to the ground by Doomsday, and smirked as she stopped the first bullet fired at a group of hostages in London.
Wonder Woman's outfit has varied over time, although almost all of her outfit incarnations have retained some form of chestplate, subligaculum, tiara, bracelets, and her signature five-pointed star symbols. When Wonder Woman was first introduced, she wore a heavily patriotic skirt and red top which incorporated an American eagle and elements of the United States flag, reflecting the comic's origins during World War II. Later artists introduced what would become Wonder Woman's classic ensemble, adding an armored plate to her top whose design recalls a letter W and revealing blue short shorts, whose precise length varied from artist to artist. Other artists have experimented with different looks for Wonder Woman over the years, including an all-white mod jumpsuit, a biker outfit, a variation of her mainstream depiction featuring leather pants and a jacket, and a number of armoured battlesuits. Contemporary artists have attempted to emphasise Wonder Woman's traditional outfit as a red armored top with a blue gladiator skirt.
She is able to astrally project herself into various lands of myth. Her physical body reacts to whatever happens to her on the mythical astral plane, leaving her body cut, bruised, or sometimes strengthened once her mind and body are reunited. She can apparently leave the planet through meditation and did this once to rescue Artemis while she was in Hell.
He flies out of the Kryptonian ship and lands in Heroes Park where Aquaman, Cyborg, Flash and Wonder Woman meet him. They notice that something is wrong with him, to which Clark uses his x-ray vision to scan the League before Cyborg accidentally launches a missile at him as his cybernetic body registers him as a threat. Superman attacks Cyborg with his heat vision as the rest of the Justice League try to subdue him, but he swiftly overpowers them.
After defeating Giganta in battle, Wonder Woman was approached by a lawyer who informed her that she had inherited the estate of Hercules, who had been killed. Shortly thereafter, she was told by A.R.G.U.S. that Hercules' body came from an area containing traces of energy unique to Apokolips. Diana visited Hercules' home and found a letter addressed to her, informing her of the location of her twin brother, Jason. She found him in Greece, and the two seemingly began to bond, only for Jason to turn against Diana after the arrival of Grail, who he had secretly allied himself with. Grail had begun killing children of the earthly gods in order to use their divine power to restore her father Darkseid to adulthood, as he had been turned into a baby at the end of the Darkseid War. Jason allied himself with her in order to exact revenge on Wonder Woman, as he resented her for not seeking him out after she learned of his existence some time ago and was envious of her. However, as Darkseid was about to drain Diana's life force, Jason regretted his actions and joined Wonder Woman in battle against Grail and Darkseid. Then, Hercules' lawyer revealed his true identity as the King of the Gods himself, Zeus. Zeus fought Darkseid while Wonder Woman took on his daughter, Grail. Ultimately, Zeus was defeated and his life force was drained by Darkseid, restoring the Apokoliptian to his full adult form. The Justice League arrived, forcing Darkseid and Grail to retreat through a Boom Tube. In the aftermath of the battle, Diana forgave her brother for his deceit.
Throughout Diana's childhood, she was training and sparring with her Amazonian sisters. One day when pilots were test flying, one of the pilots called Steve Trevor, has an accident with his plane, and Hippolyta opens Themyscira's shields and disguise, and Steve Trevor lands his plane on Paradise Island. Steve then proceeds to explore the island, and that's where he finds beautiful women bathing, but while staring at the women, Diana surprises him from behind and takes him out by kicking him in his testicles. Steve is then strapped up because of Hippolyta keeping him safe until someone proves worthy enough to escort him back to the USA. Wonder Woman while covered in a helmet, wins the challenges and gets to escort Steve back home, but while the challenges were going on, a traitor in the Amazons freed Ares because she loved him. Ares is free, and he goes to Hades so he could remove the bracelets blocking his powers.Throughout being in USA, Diana also tries to stop Ares' plans as Wonder Woman, but she fails the first time, and Ares gets ahold of the power he was searching for. After calling in his army, the US finds an island that appeared out of nowhere on the map, that being Paradise Island. They set off a nuke towards Paradise Island, and Steve manages to stop it, and at the same time, Wonder Woman defeats Ares with help from her Amazonian sisters. She realizes her feelings for Steve, and she kisses him, but when being back in Paradise Island, she looked sad. Hippolyta allowed her to operate in the outside world where she shared her feelings and her life with Steve.
Following the events of Infinite Crisis, she disappeared for a year in order to rediscover herself, and took part briefly in the events of 52. In the span of One Year Later, she was re-imagined once again and was forgiven by Batman and Superman while given her third ongoing monthly title. Batman helped her establish a role at the Department of Metahuman Affairs under the name of Diana Prince (paying homage to her golden age alter ego.) She worked alongside Tom Tresser and eventually became romantically involved with him. A move among fans across the different companies occurred with characters reverting to their original numbering of series (this for instance happened to Iron Man at Marvel as well) and the third Wonder Woman series was relaunched with Wonder Woman #600. This was actually accurate at the time as it was the indeed the 600 issue released (not including issues numbered otherwise such as with a zero or a million). Issue 600 was used as a chance to reinvent the character as she discovers herself with no memories and in a new costume. This was a short lived experiment as the entire DC lineup was soon to be re-imagined into the new 52, though certain aspects of her redesigned costume remained.
