During the fight, Steve approaches Diana who can't hear him speak due to an explosion temporarily rupturing her eardrums. Steve, after much talking, departs and leaves Diana with his watch before boarding the plane which is taking off with the mustard gas. Ares eventually restrains Diana, imploring her to surrender and realize the futility of their fight. Diana notices the plane in the sky as she's pinned to the ground and watches in horror as it explodes with Steve sacrificing himself to save billions of lives.
The Invisible Plane appeared in the very first comic stories, including All-Star Comics #8, where it is shown as being able to fly at over 2,000 mph (3,200 km/h) and to send out rainbow rays that penetrate the mist around Paradise Island, as well as landing stealthily and having a built-in radio. Wonder Woman is seen storing the plane at an abandoned farm near Washington, D.C., in the barn; she goes there as Lt. Prince and changes clothes in some of the earliest tales. Though never explicitly stated, the Plane is presumably stored there when not in use for the rest of the Pre-Crisis era. In a story published shortly after, it flies at 40 miles (64 km) a second.
Nick Pumphrey stated that Wonder Woman stands as a non-violent beacon of hope and inspiration for women and men. Grant Morrison stated "I sat down and I thought, 'I don't want to do this warrior woman thing.' I can understand why they're doing it, I get all that, but that's not what [Wonder Woman creator] William Marston wanted, that's not what he wanted at all! His original concept for Wonder Woman was an answer to comics that he thought were filled with images of blood-curdling masculinity, and you see the latest shots of Gal Gadot in the costume, and it's all sword and shield and her snarling at the camera. Marston's Diana was a doctor, a healer, a scientist."
As Diana, Victor and Arthur all try to simultaneously flank Superman (albeit unsuccessfully), Barry attempts to help using his speed, but Superman is able to see him and keeps up with the speedster. Despite Barry's best efforts, Superman is able to land a glancing blow, knocking him out before Batman arrives and gets Superman to stop. Wonder Woman tries to fight Superman again, yet she's knocked down. He then swats Batman and asks him the same question that Bruce asked him "Tell me, do you bleed?". Before Superman could kill Bruce, Lois and Alfred to stop him.
Not long after this, Athena sensed a dark destiny for the gods amidst the cosmic mechanations of Alexander Luthor Jr.. In the crisis created by his chaos, Diana was forced to kill Maxwell Lord, and incurred the ire of the world's public. The U.S. government responded by mobilizing against Themyscira, and Diana realized that as long as she was a target, the Amazons would never be safe. Diana prayed to the gods to take the Amazons to safety, but got more than she bargained for. On Olympus, she pleaded against Athena's decision to remove the gods from Earth's affairs. Regardless, the gods departed, leaving Diana bereft of family and faith.
Despite helping win the war, defeating Ares and still loving humanity, Diana is still left sobered, emotionally broken, psychologically scarred, and devastated over not having been able to save the Belgian village from Dr. Poison, as well as over her beloved Steve Trevor's self-sacrificing death. Indeed, Diana would later claim that she "would never be the same" ever again after World War I. Moreover, in the years that followed, Diana bore witness to a "century of horrors" (Wars, Fascism, Communism, nuclear weapons' deployment, geopolitical brinkmanship, racism, homophobia, genocides, war crimes, propaganda, and etc.), and due to all of this occurring without Ares being there to spread corruption, Diana almost completely lost faith in humanity, coming to believe that humans "made a world where standing together is impossible". As such, Diana resolved to mostly abandon superheroism for 100 years.
In Wonder Woman Vol. 1 #204, Diana's powers and costume were returned to her and she is once again reinstated as Wonder Woman. I-Ching is killed by a crazy sniper in the same issue. Later, Diana meets her sister Nubia, who is Hippolyta's daughter fashioned out of dark clay (hence Nubia's dark complexion). Nubia claimed to be the "Wonder Woman of The Floating Island", and she challenges Diana to a duel which ends in a draw. Returning to her home, Nubia would have further adventures involving Diana.
As Wonder Woman joins the Battle against Doomsday, she arrives just in time to save Batman from Doomsday's lethal thermal blast, deflecting the beams with her indestructible bracelets. She then jointly attacks Doomsday with Superman while Batman tries to expose the creature to Kryptonite, allowing its destruction. She relentlessly battles the monster, and despite Doomsday being stronger, Wonder Woman held her own, parrying a tremendous punch with the Sword of Athena, and then slicing off Doomsday's right arm with it. Eventually, Batman baits the monster into coming closer to her, allowing Wonder Woman to hurl the noose of her unbreakable Lasso of Hestia around his torso.
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.
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.
