Lasso of Truth: The Lasso, also referred to as the Golden Perfect, is a sacred relic of the Amazons and was given to them by the Gods of Olympus. It was bestowed to Wonder Woman when she embarked to Man's World. The Lasso's most known power is to force anyone ensnared by it to speak only the truth. It also possesses a number of other magical abilities. The Lasso is capable of tethering the hearts and minds of the individuals holding it, creating a telepathic link between them, as well as allowing for language translation. It can also be used to bind and ensnare the souls of beings, including even gods, within it. Diana can use the Perfect to locate individuals who share an emotional connection to her. It can also be used to force a biophysical reset of those who have been corrupted by some external influence, such as poisons and toxins or mind control, who are bound by it. Diana is highly proficient at using the Lasso of Truth as both a tool and a weapon, and is capable of easily binding people and objects using it.
In 1944, Gaines and Marston signed an agreement for Wonder Woman to become a newspaper strip, syndicated by King Features. Busy with the newspaper strip, Marston hired an 18-year-old student, Joye Hummel, to help him write comic-book scripts. Joye Hummel, now Joye Kelly, turned 90 this April; in June, she donated her collection of never-before-seen scripts and comic books to the Smithsonian Libraries. Hiring her helped with Marston’s editorial problem, too. Her stories were more innocent than his. She’d type them and bring them to Sheldon Mayer, Marston’s editor at DC, she told me, and “He always OK’d mine faster because I didn’t make mine as sexy.” To celebrate syndication, Gaines had his artists draw a panel in which Superman and Batman, rising out of the front page of a daily newspaper, call out to Wonder Woman, who’s leaping onto the page, “Welcome, Wonder Woman!”
While in London, Wonder Woman was summoned to help a young lady called Zola from the minions of the goddess Hera and after Diana defeated the enemies, she was informed by Hermes that Zola was pregnant with Zeus’s child, which caused Hera’s wrath. Diana then took took Zola and the injured Hermes to the island of Themyscira, home of the Amazons, where Hera’s wrath reached them in the form of her daughter Strife. Wonder Woman used the Lasso of Truth to stop Strife from hurting the Amazons, but it caused her to reveal the fact that Diana and her were sisters. The next day, Diana learned from her mother that she was in fact Zeus’ daughter and, hurt by her existence being a lie, she decided to renounce the name Diana, and swore never to return to the island again.
The "Year One" storyline retells Diana's origin growing up on Themyscira. She lives an idyllic life and harbors interest for the outside world, and the first connection to it comes in the form of Steve Trevor, who crashes on the island and is the sole survivor. A contest is held to determine which Amazon is the best candidate to take Steve home, with Diana volunteering despite knowing the cost to leave the island is to never return. Diana wins the contest and departs with Steve. Once arriving in America, Diana is taken into custody by the government to discern her origins. She meets Etta Candy and Barbara Ann Minerva along the way. While incarcerated Diana is visited by the gods in animal form and bestow upon her powers of strength, speed, agility, durability, and flight. She discovers Ares, the god of war, is working to destroy humanity. Accepting her new role in Man's World, Diana, with the help of the gods in animal form, subdues Ares with the lasso. Now called Wonder Woman, Diana becomes one of the world's greatest heroes.
The team learns that a gala will be held at the nearby German High Command. Steve and Diana separately infiltrate the party, with Steve intending to locate the gas and destroy it, and Diana hoping to kill Ludendorff, believing that he is Ares and thus killing him will end the war. Steve stops her to avoid jeopardizing his mission, but this allows Ludendorff to unleash the gas on Veld, killing its inhabitants. Blaming Steve for intervening, Diana pursues Ludendorff to a base where the gas is being loaded into a bomber aircraft bound for London. Diana fights and kills him, but is confused and disillusioned when his death does not stop the war.
When faced with a larger threat, Diana will wear her Amazon battle armour for added protection as well as use martial weapons such as swords. Technically speaking as well, as reimagined under the George Perez 1980s reboot, the iconic costume is in fact simply the breastplate of this armour. She will also additionally use a shield for added defense when she deems it necessary.
The events of Crisis on Infinite Earths greatly changed and altered the history of the DC Universe. Wonder Woman's history and origin were considerably revamped by the event. Wonder Woman was now an emissary and ambassador from Themyscira (the new name for Paradise Island) to Patriarch's World, charged with the mission of bringing peace to the outside world. Various deities and concepts from Greek mythology were blended and incorporated into Wonder Woman's stories and origin. Diana was formed out of clay of the shores of Themyscira by Hippolyta, who wished for a child; the clay figure was then brought to life by the Greek deities. The Gods then blessed and granted her unique powers and abilities – beauty from Aphrodite, strength from Demeter, wisdom from Athena, speed and flight from Hermes, Eyes of the Hunter and unity with beasts from Artemis and sisterhood with fire and the ability to discern the truth from Hestia. Due to the reboot, Diana's operating methods were made distinctive from Superman and Batman's with her willingness to use deadly force when she judges it necessary. In addition, her previous history and her marriage to Steve Trevor were erased. Trevor was introduced as a man much older than Diana who would later on marry Etta Candy. Instead, Perez created Julia and Vanessa Kapatelis, a Greek-American scholar and her teenage daughter whom Diana would live with when she was in Man's world and would be major supporting characters in the series for years.
