Although she has traditionally paired with either Steve Trevor or no one as a main romantic lead, and Superman with either Lois Lane or Lana Lang, there has often been the hint of a romance between the two characters. This began in the 1960 in the series Superman's Girlfriend, Lois Lane which was equal parts romance and action themed. In order to drive along the romance, the theme often came up of Lois Lane believing that Superman really loved Wonder Woman (though this was mostly for the purposes of a case.) In later years the same ideas perpetuated though most in imaginary stories or alternate tellings of the future. Following Crisis on Infinite Earths the characters were briefly linked romantically in Action Comics #600 which was written by John Byrne. Subsequently the characters' interest in one another was generally portrayed as a strong friendship (this occurred under different writers, primarily Messner-Loebs and Rucka.) Following the reboot of the DC universe into the new 52 the characters once again showed a romantic interest in one another. They found common ground in the isolation which their power give them and shared a kiss in Justice League #12 in 2012. It was later on revealed by Geoff Johns that their relationship wouldn't last for long and will end badly.
After Crisis on Infinite Earths, the character’s origin was slightly retold by Greg Potter and George Perez. In this version, the Amazons were reincarnations of the souls of abused and murdered women from ancient days. In 1200 B.C. a debate occurred on Mount Olympus on how mankind should be made to relate to the gods. Ares, the god of war and destruction, wanted to descend upon the world with his army and crush mankind submission. This was opposed by the others gods present including Artemis, who wanted peace and suggested creating a new race that would lead humans on the right path. Zeus rejected their arguments, and they decided to proceed without his blessing. With the aid of Charon the ferryman, the gods reached the Womb of Gaea, where the souls of women who were abused and murdered at the hands of men were preserved by Gaea herself. Artemis then sent the souls to Greece where they reincarnated into adult women. Aphrodite observed that one soul still remains in the Womb, to which Athena replied that the time had not yet come for that one. The new race in Greece were approached by the goddesses, who bestowed upon them several blessings, charging them with the purpose of leading humanity in the ways of Gaea. They then appointed Hippolyte and Antiope as co-rulers. The civilization is named the Amazons. Stories of this civilization spread throughout Greece and reached the ears of Heracles, who was being manipulated by Ares into attacking the Amazons. Heracles approached the Amazons but was defeated by Hippolyte, upon which he pretended friendship and declared the Amazons allies. When their guard was down, the Greeks drugged the Amazons, taking Hippolyte, Antiope and the other survivors captive. In her cell, Hippolyte is freed by Athena ,who reminds her of her purpose and asked her to avoid revenge and pursue peaceful means. Hippolyte escaped and freed the rest of the Amazons. She shared Athena's message to the Amazons, but blinded by their thirst for revenge, they ruthlessly slaughter the remaining men. Antiope gave Hippolyta her girdle and left to pursue revenge The goddesses appeared and told them they had failed in their purpose and banished them to an island to guard the terrible evil within, as penance. They were granted immortality as long as they did not stray from their new purpose, which would eventually purify their souls. The Amazons built a nation and lived there for 4,000 years. It is during this time that Hippolyte, sole leader of the Amazons, felt an unexplained yearning. Menalippe, the Oracle, told her she was the only Amazon pregnant at the time of her previous incarnation's death, and thus the yearning she felt was the call of her unborn child. As per her advise, Hippolyte went to the shore at sunrise and made a clay figure of a baby. She then cried out to Artemis. The gods, recognizing it was time for the remaining soul in Gaea's womb to depart, infused it into the clay form, which then incarnated as a real child. Blessed with Gaea's greatest gift, life, the gods present bestowed their gifts upon the newborn: Demeter granted the baby great strength, Aphrodite granted her great beauty and a loving heart, Athena granted her great wisdom, Artemis granted her the eye of the hunter and unity with beasts, Hestia granted her sisterhood with fire, and Hermes gave her great speed and the power of flight. Hippolyte named her after a holy warrior, Diana, and she grew up knowing the love of a thousand mothers. Thus Diana of Themyscira was born.
Wonder Woman was now a princess and emissary from Paradise Island (called Themyscira) to Patriarch's world. She possessed stunning beauty and a loving heart, gifts from the goddess Aphrodite. From Athena, she received the gift of great wisdom; from Demeter, the power and strength of the earth; from Hestia, sisterhood with fire; and from Artemis, unity with beasts and the instincts and prowess of a hunter. Finally, Diana received the gift of speed and the power of flight from the god Hermes.
Superhuman Durability: Diana possesses a high resistance to damage and magical attacks. Her resistance to injury is not quite as great as Superman or Supergirl. However, due to her vast threshold for pain and her Amazonian ability to heal at a superhuman rate, this easily makes up for the difference. She has withstood considerable bludgeoning damage in the form of hand to hand combat with metahuman opponents such as Superman and Shazam. She has considerable resistance to human weaponry, though this is not absolute; bullets, and edged weapons can cause minor to moderate injury, but never life threatening. She once survived an Eighth Metal bullet to the head and was back on her feet and fighting again a few moments later.
Upon becoming a super-heroine, Wonder Woman became a founding member of the Justice League. Her ambassadorial duties required her to visit Washington D.C., with army officer Steve Trevor as her liaison. When Parademons stormed Metropolis, Wonder Woman resolved to defend the city, meeting the heroes Superman, Batman, Flash, Green Lantern and Aquaman. They also met the young hero Cyborg, who attempted to warn them against the evil alien conqueror Darkseid. Unfortunately, Cyborg's warnings were meaningless, as Darkseid had already arrived. Although Darkseid had initially beat them without effort, Green Lantern rallied them in order to confront Darkseid as a team. Wonder Woman proved crucial in Darkseid's defeat, stabbing him in one of his eyes to prevent him from using his Omega Beams. This gave Superman and Cyborg enough time to throw Darkseid back into his home-world.
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.
