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.
After Sekowsky's run ended in the early 1970s, Diana's roots were reverted to her old mythological ones and she wore a more modernized version of her original outfit, a predecessor to her "bathing suit" outfit. Later, in 1976, her glowing white belt was turned into a yellow one. For Series 3, artist Terry Dodson redrew her outfit as a strapless swimsuit.
Starting in Wonder Woman vol. 2 #51, the Amazons, who had revealed their presence to the world in Wonder Woman vol. 2 #50, are blamed for a series of murders and for the theft of various artifacts. The Amazons are then taken into custody, Queen Hippolyta is nowhere to be found and Steve Trevor is forced by General Yedziniak to attack Themyscira. These events lead to the "War of the Gods" occurring. The culprit of the murders, thefts and the framing of the Amazons is revealed to be the witch Circe, who "kills" Diana by reverting her form back into the clay she was born from. Later, Wonder Woman is brought back to life and together with Donna Troy, battles Circe and ultimately defeats her. Circe would later return by unknown means.
The Lasso of Truth, or Lasso of Hestia, was forged by Hephaestus from the golden girdle of Gaea. The original form of the Lasso in the Golden Age was called the Magic Lasso of Aphrodite. It compels all beings who come into contact with it to tell the absolute truth and is virtually indestructible; in Identity Crisis, Green Arrow mistakenly describes it as "the only lie detector designed by Zeus." The only times it has been broken were when Wonder Woman herself refused to accept the truth revealed by the lasso, such as when she confronted Rama Khan of Jarhanpur, and by Bizarro in Matt Wagner's non-canonical Batman/Superman/Wonder Woman: Trinity. During the Golden Age, the original form of the Lasso had the power to force anyone caught to obey any command given them, even overriding the mind control of others; this was effective enough to defeat strong-willed beings like Captain Marvel. Diana wields the Lasso with great precision and accuracy and can use it as a whip or noose.
Impressed by this unknown woman's self-sacrifice, the Amazons entombed her with honors and clothed her in armor displaying the American flag pattern on her uniform, which they assumed were her heraldic colors. Trevor's legacy was also the primary reason why Ares arranged for Steve Trevor to bomb the island, as he could not resist the irony of the heroine's son unwittingly killing her admirers.
