After defeating Giganta in battle, Wonder Woman was approached by a lawyer who informed her that she had inherited the estate of Hercules, who had been killed.[89] Shortly thereafter, she was told by A.R.G.U.S. that Hercules' body came from an area containing traces of energy unique to Apokolips. Diana visited Hercules' home and found a letter addressed to her, informing her of the location of her twin brother, Jason. She found him in Greece,[90] and the two seemingly began to bond, only for Jason to turn against Diana after the arrival of Grail, who he had secretly allied himself with.[91] Grail had begun killing children of the earthly gods in order to use their divine power to restore her father Darkseid to adulthood, as he had been turned into a baby at the end of the Darkseid War. Jason allied himself with her in order to exact revenge on Wonder Woman, as he resented her for not seeking him out after she learned of his existence some time ago and was envious of her. However, as Darkseid was about to drain Diana's life force, Jason regretted his actions and joined Wonder Woman in battle against Grail and Darkseid. Then, Hercules' lawyer revealed his true identity as the King of the Gods himself, Zeus.[92] Zeus fought Darkseid while Wonder Woman took on his daughter, Grail. Ultimately, Zeus was defeated and his life force was drained by Darkseid, restoring the Apokoliptian to his full adult form. The Justice League arrived, forcing Darkseid and Grail to retreat through a Boom Tube. In the aftermath of the battle, Diana forgave her brother for his deceit.[93]
During the Silver Age, under writer Robert Kanigher, Wonder Woman's origin was revamped,[32] along with other characters'. The new origin story increased the character's Hellenic and mythological roots: receiving the blessing of each deity in her crib, Diana is destined to become as "beautiful as Aphrodite, wise as Athena, strong as Hercules, and swift as Hermes."[33]

Development for a live action Wonder Woman feature film began in 1996, with Ivan Reitman attached as producer and possible director.[66] In 1999 the project became attached to Jon Cohen, who adapted Wonder Woman for producer Joel Silver, with the hope that Sandra Bullock would star.[67] By 2001, Todd Alcott was hired to write the screenplay, with Silver Pictures backing the project.[68] At that time, performers such as Mariah Carey and Catherine Zeta-Jones were also rumored to be possible candidates for the role of Wonder Woman.[69] Leonard Goldberg focused on Bullock[70] who said that she was approached for the role. Lucy Lawless, the star of Xena: Warrior Princess, was also under consideration, though she stated that she would have been more interested if Wonder Woman was portrayed as a "flawed hero".[71] The screenplay went through various drafts written by Alcott, Cohen, Becky Johnston, and Philip Levens,[72] and by August 2003, Levens had been replaced by screenwriter Laeta Kalogridis.[73]

Due to the reboot of the character following Crisis on Infinite Earths, numerous things no longer made sense in terms of continuity as it related to the remainder of the DC Universe. As her first overall appearance was now in continuity around the Legends miniseries, it no longer made sense that she was a founding member of the Justice League of America. This founding position was instead given retroactively to Black Canary. Later it was decided that she should be given this position back and thus both she and Black Canary were considered founding members of the Justice League. In reference to the Justice League though, although she has more than 400 combined appearances therein, she has had most of her character development in her own series.
The Lasso of Truth, or Lasso of Hestia, was forged by Hephaestus from the golden girdle of Gaea.[182] 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;[182] 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,[206] and by Bizarro in Matt Wagner's non-canonical Batman/Superman/Wonder Woman: Trinity.[207] 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.[208] Diana wields the Lasso with great precision and accuracy and can use it as a whip or noose.
