Wonder Woman's character was created during World War II; the character in the story was initially depicted fighting Axis military forces as well as an assortment of colorful supervillains, although over time her stories came to place greater emphasis on characters, deities, and monsters from Greek mythology. Many stories depicted Wonder Woman rescuing herself from bondage, which defeated the "damsels in distress" trope that was common in comics during the 1940s. In the decades since her debut, Wonder Woman has gained a cast of enemies bent on eliminating the Amazon, including classic villains such as Ares, Cheetah, Doctor Poison, Circe, Doctor Psycho, and Giganta, along with more recent adversaries such as Veronica Cale and the First Born. Wonder Woman has also regularly appeared in comic books featuring the superhero teams Justice Society (from 1941) and Justice League (from 1960).
Wonder Woman figures were released for Justice League and Justice League Unlimited. Prior to that, there were plans for a show called Wonder Woman and the Star Riders, which similar to Sailor Moon, would have featured Wonder Woman leading a team of teen magical girls. Prototype dolls for the series were made. There was also a statue from the animated Wonder Woman movie and a Wonder Woman action figure for the Justice League War movie. Wonder Woman dolls and figures were also released for the DC Super Hero Girls line.
In the Golden Age, Wonder Woman adhered to an Amazon code of helping any in need, even misogynistic people, and never accepting a reward for saving someone; while conversely, the modern version of the character has been shown to perform lethal and fatal actions when left with no other alternative, exemplified in the killing of Maxwell Lord in order to save Superman's life.
On occasions Wonder Woman has employed a magical sword of unknown (though presumably Amazon) origin. This sword has been used most specifically against those with the power of invulnerability as invulnerability generally does not work against magical items. It is generally represented as a short sword. In Wonder Woman (vol. 4) #15, Hephaestus modifies Diana's bracelets so that she can manifest two short swords from them during battle.
The Crisis on Infinite Earths crossover of 1986 was designed and written with the purpose of streamlining most of DC's characters into one more-focused continuity and reinventing them for a new era, thus Wonder Woman and Steve Trevor were declared to come from the Earth-Two dimension, and along with all of their exploits, were erased from history, so that a new Wonder Woman character, story and timeline could take priority.
