Marston was a man of a thousand lives and a thousand lies. “Olive Richard” was the pen name of Olive Byrne, and she hadn’t gone to visit Marston—she lived with him. She was also the niece of Margaret Sanger, one of the most important feminists of the 20th century. In 1916, Sanger and her sister, Ethel Byrne, Olive Byrne’s mother, had opened the first birth-control clinic in the United States. They were both arrested for the illegal distribution of contraception. In jail in 1917, Ethel Byrne went on a hunger strike and nearly died.
Although she initially forbids Diana to be trained as a warrior, Hippolyta reluctantly agrees to let General Antiope, Hippolyta's sister and Diana's aunt, train her, only more rigorously than any other warrior. In 1918, Diana, now a young woman, rescues US pilot Captain Steve Trevor when his plane crashes off the Themysciran coast. The island is soon invaded by German soldiers that had been pursuing Trevor. The Amazons kill the crew, but Antiope sacrifices herself to save Diana. Steve is interrogated with the Lasso of Hestia and reveals that a great war is consuming the outside world and that he is an Allied spy. He has stolen a notebook of the chief chemist Dr. Isabel Maru, who is attempting to engineer a deadlier form of mustard gas under the orders of General Erich Ludendorff from a weapon facility in the Ottoman Empire. Believing Ares to be responsible for the war, Diana arms herself with the "Godkiller" sword, the lasso, and armor before leaving Themyscira with Steve to locate and stop Ares for good.
Soon thereafter, the gods secreted themselves away for a conference. At this time, Darkseid attacked Olympus. The dark god ceased hostilities, though, as soon as he realized the place was deserted. When the gods returned, they had decided upon destroying Mount Olympus and undertaking a "cosmic migration" to the stars. Over Hermes' objections, they took several steps. First, the three elder brothers made a new pact to replace the original pact which divided Earth among them. Then, they combined the will of all the gods (minus Ares) and the strength of Amazon prayer, and used Diana's bracelets to amplify that power (the bracelets are all that remained of Zeus' Aegis; this Aegis was made from the hide of Amalthea, the goat which reared him. Thus, the old home was demolished and New Olympus was created. In order to properly establish this new home, it was necessary for the Gods to sequester themselves indefinitely.
The final remaining relics Darkseid needed were being guarded by A.R.G.U.S. at their HQ, so Darkseid decided to use a Boom Tube to transport the building and all its contents to his base in the Amazon Rainforest. The Female Furies retrieved the relics and put them into place while Wonder Woman fought Darkseid. With the relics' power, Darkseid was able to open a portal to Themyscira. As it is impossible for one who has set foot on Themyscira to return after leaving, Diana was unable to follow Grail through the portal. Grail invaded and began transforming the Amazons into creatures resembling Darkseid's Parademons. As Jason had never actually set foot on Themyscira, he followed Grail and met his mother Hippolyta for the first time since his birth. While Jason and Hippolyta fought off the transformed Amazons, Wonder Woman was able to defeat Darkseid through her love for her deceased father, Zeus, and her half-siblings, calling their spirits out of Darkseid's body and destroying him from the inside. The Amazons captured Grail and imprisoned her in the prison beneath Themyscira, alongside Ares, while Darkseid re-emerged somewhere on Earth. Jason was gifted a magical spear from his mother and returned to Earth.
A warning that is first heard from the lips of Cheetah as she attempts to escape captivity, yet is echoed by others around the globe, all putting Wonder Woman on alert. As she attempts to investigate, she is attacked by Supergirl, wanting vengeance for the death of Rao, as the influence has gotten to her as well. An epic battle breaks out, and once again, the trusty Lasso of Truth saves the day, though barely.
With Zola's pregnancy reaching full term, she insisted on seeing her own doctor in Michigan. While there, they were all attacked by Artemis and Apollo. Unprepared, Diana and her companions were defeated, and Zola was taken to Mount Olympus to be delivered to Hera in exchange for the throne. Apparently, Hera was willing to give up her throne for the sake of revenge. However, she had expected Zeus to return as soon as his rule was threatened, which he did not. When Apollo sat on the throne, he was crowned ruler, and when he learned of Hera's deceit, he exiled her from Olympus.
Diana and Trevor arrived at the British War Council's meeting place. Trevor told her to stay behind while he retrieved one of his superiors from the war room. Curious, she followed him into the room, where dozens of men argued with each other while Sir Patrick Morgan struggled to be heard. The room fell silent as the men noticed Diana, as women were not allowed in the room; Trevor quickly escorted her out.
Writer Gerry Conway brought Steve Trevor back to life again in issue #271 (September 1980). Following Diana's renunciation of her role as Wonder Woman, a version of Steve Trevor from an undisclosed portion of the Multiverse accidentally made the transition to Earth-One. With Diana's memory erased by the Mists of Nepenthe, the new Steve again crash-landed and arrived at Paradise Island. After reclaiming the title of Wonder Woman, Diana returned to Military Intelligence, working with Trevor and re-joined by supporting characters Etta Candy and General Darnell.
Immortality: Wonder Woman, due to being an Amazon, has lived for millennia without visibly aging, with her being roughly 5000 years old (having been born right after the War of the Gods), and having been present in the "Man's World" since World War I. She is thus the oldest member of the Justice League by far (though still roughly a millenia younger than Enchantress, and even more so than Ares and Steppenwolf), making her an ageless immortal, much like Superman.
In her debut in All Star Comics #8, Diana was a member of a tribe of women called the Amazons, native to Paradise Island – a secluded island set in the middle of a vast ocean. Captain Steve Trevor's plane crashes on the island and he is found alive but unconscious by Diana and fellow Amazon, and friend, Mala. Diana has him nursed back to health and falls in love with him. A competition is held amongst all the Amazons by Diana's mother, the Queen of the Amazons Hippolyta, in order to determine who is the most worthy of all the women; Hippolyta charges the winner with the responsibility of delivering Captain Steve Trevor back to Man's World and to fight for justice. Hippolyta forbids Diana from entering the competition, but she takes part nonetheless, wearing a mask to conceal her identity. She wins the competition and reveals herself, surprising Hippolyta, who ultimately accepts, and must give in to, Diana's wish to go to Man's World. She then is awarded a special uniform made by her mother for her new role as Wonder Woman and safely returns Steve Trevor to his home country.
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.
In 1954, Dr. Fredric Wertham alleged that there were lesbian subtexts to Wonder Woman and claimed comics contributed to juvenile delinquency in his book Seduction of the Innocent where despite a very obvious heterosexual relationship with Steve Trevor, Wertham asserted that Wonder Woman’s association with the Holliday Girls could be interpreted as a lesbian relationship. The Comics Code Authority was then introduced in reaction to Wertham 's claims against the entire industry.
