Later, Diana is seen in the Gotham City Museum of Antiquities (with ancient Greco-Roman exhibits), conversing with an elderly couple, when the curator comes up, and offers to show her something of interest. She politely excuses herself and follows him to the exhibit of the fake replica of Alexander the Great's sword, which the ancient conqueror of the Middle East had used to cut the Gordian knot.
By the end of the war, Diana began to lose faith in both humanity and herself after Ares opened her eyes to humanity's potential for evil. While she still believed in the power of love and compassion to change humanity for the better, Diana was left sobered and emotionally broken over certain events from the war, such as the use of Dr. Poison's gas to massacre the entire village of Veld, and Steve Trevor's self-sacrificing death. After witnessing a "century of horrors", Diana largely stepped away from heroics until she witnessed the seemingly unstoppable Doomsday wreck havoc; ultimately joining in to battle him alongside Batman and Superman. After witnessing Superman's own sacrifice to stop the monster, however, Diana turned once again towards heroics; demonstrating not only her underlying belief in her own core values, but also in the positive effect true heroes can have on the world.
Wonder Woman continued to use the plane for super speed, outer space, and multi-dimensional transport up until the unpowered era of Diana Prince. When Wonder Woman resumed superpowered, costumed operations in 1973, she continued to use the jet as before, but did glide on air currents for short distances. At one point, Aphrodite granted the plane the power to fly faster than the speed of light for any interstellar voyages her champion might undertake. Thanks to tinkering by gremlins, the Plane even developed intelligence and the power to talk. The plane proved a good friend, eager to help his "mistress" and her loved ones in any way possible. It got along especially well with Steve Trevor.
Until DC's New 52 relaunch, there were a few other aspects of the origin story that remained consistent. Her mother, Hippolyta, created her out of clay, and the Greek gods bestowed her with life. She grew up among the Amazons who taught her the skills of a warrior as well as the lessons of peace and love. When Steve Trevor, an American pilot, crash landed on Paradise Island, the Amazons had a contest to determine who should receive the honor and responsibility to take him back to Man’s World and serve as the champion emissary of all the Amazons represent.
Wonder Woman and the other heroes were finally released from the Firestorm Matrix when Batman used the Lasso of Truth on Firestorm. Superman was still infected with the Kryptonite shard inside his nervous system, but Lex Luthor was able to extract it, saving Superman's life. Luthor also assembled a group of villains that defeated the Crime Syndicate. Later, at the Batcave, Wonder Woman and the Justice League talked about the enemy that destroyed the Crime Syndicate's world and came to the conclusion that Darkseid would return.
