Wonder Woman’s powers are a result of the blessings she received from the gods (or presumably in the modern version by her divine ancestry), but originally came from her "brain energy" training. Her abilities in large part come from her upbringing in the martial society of the Amazons. She is one of the most powerful superheroes in the DC universe.
Even alongside all of her kindness, compassion, and empathy, Diana is still also a warrior at heart, and when someone she cares about is hurt, becomes far more relentless and ruthless. When seemingly beaten by Ares (who was only growing more powerful from her violence, rage, and hatred), and after having to watch her beloved Steve Trevor die, she flew into an agonizing rage, and she assaulted and brutalized several armed German soldiers with immense speed and ferocity. She even came close to murdering Dr. Poison as vengeance for Steve's death; but after recalling Steve's great love for an undying belief in her and her beliefs, restrained herself and refocused her energies on Ares, harnessing her love for Trevor to overcome her violent emotions and swiftly overpower an angered Ares. Additionally, she resolved to fight even harder after Steppenwolf revealed that he had killed several other Amazons. Outside of battle, however, Diana can also react indigently and negatively towards people who disrespect her, her relatives, or those she cares about. Two such notable instances were when she shot an angry look at Lex Luthor (after he insulted her father Zeus's memory), and when she shoved back Batman (after he had insulted her beloved Steve Trevor's memory). Diana also remains ruthless when facing enemies in battle as Wonder Woman, and she even shows signs of enjoying a good battle when they put up a good fight. This was seen when she briefly smiled and laughed when she was beaten to the ground by Doomsday, and smirked as she stopped the first bullet fired at a group of hostages in London.
The I Ching era had an influence on the 1974 Wonder Woman TV movie featuring Cathy Lee Crosby, in which Wonder Woman was portrayed as a non-superpowered globe-trotting super-spy who wore an amalgam of the Wonder Woman and Diana Prince costumes. The first two issues of Allan Heinberg's run (Wonder Woman vol. 3, #1–2) include direct references to I Ching, and feature Diana wearing an outfit similar to that which she wore during the I Ching era.
Hidden behind this controversy is one reason for all those chains and ropes, which has to do with the history of the fight for women’s rights. Because Marston kept his true relationship with Olive Byrne a secret, he kept his family’s ties to Margaret Sanger a secret, too. Marston, Byrne and Holloway, and even Harry G. Peter, the artist who drew Wonder Woman, had all been powerfully influenced by the suffrage, feminism and birth control movements. And each of those movements had used chains as a centerpiece of its iconography.
In her false memories, the Amazons traditionally procreated by raping and then murdering sailors who happened too close to their island. Hippolyta was barren, and legend told that Diana was born of her mother's strong desire for a child, a lump of clay brought to life in the form of a girl; the perfect Amazon, as she was born of no man. The truth, though, was that Hippolyta had had an affair with Zeus, and Diana's real parentage was hidden in order to protect the Queen and her daughter from the wrath of Zeus' notoriously jealous wife Hera. Unbeknownst to Diana, her mother also gave birth to her twin, a brother named Jason.
The Diana Prince alias also played an important role after the events of Infinite Crisis. Wonder Woman was broadcast worldwide killing a villain named Maxwell Lord, as he was mind controlling Superman into killing Batman. When Wonder Woman caught him in her lasso, demanding to know how to stop Superman, Maxwell revealed that the only way to stop him was to kill Lord, so as a last resort Diana snapped his neck. To recover from the trauma of killing another person, the Amazon went into a self-imposed exile for one year. On her return to public life, Diana realized that her life as a full-time celebrity superhero and ambassador had kept her removed from humanity. Because of this she assumed the persona of Diana Prince and became an agent at the Department of Metahuman Affairs. During a later battle with the witch Circe, a spell was placed on Diana leaving her powerless when not in the guise of Wonder Woman.
