Introduced in All Star Comics #8 in December 1941, Wonder Woman has endured multiple interpretations and adaptations since her inception. The details of her abilities, relationships and origin have changed and evolved over time. Intitially, Wonder Woman is an Amazon champion, armed with bulletproof bracelets, magic lasso, and Amazonian training, who wins the right to return Steve Trevor to "Man's World" and fight the evil of the Nazis. While Wonder Woman fights both Nazis and crime, her appearances had a noted sexual subtext, leading to debates over whether it provided an outlet for Dr. Marston's sexual fantasies or whether it was meant to appeal or influence, the developing sexuality of young readers.
During this period Wonder Woman joined the Justice Society of America as the first female member; albeit as the group's secretary, despite being one of the most powerful members.
During the Silver Age, Wonder Woman's origin was revamped, along with other characters during the era. The new origin story, increased the character's Hellenic roots, receiving the blessing of each deity in her crib, Diana is destined to become "beautiful as Aphrodite, wise as Athena, stronger than Hercules, and swifter than Mercury."
The Lasso of Truth is absolutely unbreakable and has restrained beings as powerful as Superman, Captain Marvel, and the gods Ares and Hades. The Lasso burns with a magical aura called the Fires of Hestia, forcing anyone within the Lasso's confines to be truthful. The Fires can restore lost memories, dispel illusions, renew the wielder's body, protect those encircled by it from magical and nonmagical attacks, and even cure insanity.
Wonder Woman's golden tiara has also doubled as a throwing weapon, used for long-distance attack or defense. It was crafted from Apollo's discus, which returned to him whenever thrown, like a boomerang.
Diana used the Sandals of Hermes to cross the dimensional impasse between Themyscira and the outside world, but they were passed on first to Artemis, and later to Wonder Girl. Diana also once wielded the Gauntlet of Atlas, which magnifies the physical strength and stamina of the wearer by a factor of ten.
The Golden Age and Silver Age Wonder Woman used an invisible airplane that could be mentally controlled. It was variously described as being either a creation of Amazon technology or the legendary winged horse Pegasus transformed into an aircraft. Its appearance varied as well, originally having a propeller and later being drawn as a jet aircraft, resembling a fighter plane.
The Post-Crisis Wonder Woman has at her disposal a small lightweight disc of alien (Lansinar) technology that, when triggered by her thoughts, transforms into a transparent version of whatever object or vehicle is appropriate for her needs. However, following the One Year Later continuity jump, Diana was given a new invisible plane, created by Wayne Industries.
Diana occasionally uses additional weaponry in formal battle, such as ceremonial golden armor complete with golden wings, war-skirt and chest-plate, and a golden helmet in the shape of an Eagle's head. Her deadliest piece of battle-gear is a magically forged sword (again a gift from Hephaestus), so sharp that it can "carve the electrons off an atom".
