In her debut in All Star Comics #8, Diana was a member of a tribe of women called the Amazons, native to Paradise Island – a secluded island set in the middle of a vast ocean. Captain Steve Trevor's plane crashes on the island and he is found alive but unconscious by Diana and fellow Amazon, and friend, Mala. Diana has him nursed back to health and falls in love with him. A competition is held amongst all the Amazons by Diana's mother, the Queen of the Amazons Hippolyta, in order to determine who is the most worthy of all the women; Hippolyta charges the winner with the responsibility of delivering Captain Steve Trevor back to Man's World and to fight for justice. Hippolyta forbids Diana from entering the competition, but she takes part nonetheless, wearing a mask to conceal her identity. She wins the competition and reveals herself, surprising Hippolyta, who ultimately accepts, and must give in to, Diana's wish to go to Man's World. She then is awarded a special uniform made by her mother for her new role as Wonder Woman and safely returns Steve Trevor to his home country.
These are a pair of steel cuffs that are indestructible because they were created from the remains of Zeus’s Aegis shield. Wonder Woman can use her super reflexes to deflect projectiles, blades, punches, or any form of offensive attack used against her (including Darkseid’s Omega Beams). She can also use them to deflect an object back into her enemies. When Diana crosses them to protect her from impact with larger projectiles as well as damage inflicted by explosions and collisions with hard surfaces, the bracelets generate a small energy shield. In recent events, Diana has learned how to emit a devastating magic lightning attack from her bracelets do to their link with Zeus. This attack can even strike Gods and Goddesses down with a powerful strike, and this attack can even work underwater. In the golden age these were items of submission meant to control Amazons. If they were removed from an Amazon, she would launch into an uncontrollable rage, releasing her full power (this was a plot device which subdued many foes, among them the Crimson Centipede). Also during this era, if they were bound together by a man, all her powers were lost, this was only true in the Golden Age. With the launch of the new 52 the golden age bracelets are brought back. Wonder Woman removes her bracelets and go into a "berzerker rage" of power. Wonder Woman's bracelets are what protects her opponents from her intense power in the New 52.
The modern age of the character can be tied to the reboot of the character following Crisis on Infinite Earths. In this the character became defined by the vision of George Perez in a way which the entire concept of the character was defined by his direction. As opposed to the past where the character would get retold origins which would try to make her more contemporary, now she got one which tied her much more strongly to the stories of the ancient gods. For the first time Diana enters Man’s World not knowing how to speak English already, and is forced to master the language on her own. In this period she also became much more closely related with modern female issues, and this was usually through her circle of friends – Julia and Vanessa Kapatelis and Mindi Mayer. Such issues as the cultural need for women to be attractive and thin, suicide and the sensationalization of the media as it pertains to women were all addressed. This version of the character also reimagined Steve Trevor as a father figure for Diana as opposed to a romantic counterpart. After Perez’s run on the character, she was taken over for a time by William Messner Loebs, who recast her again in somewhat more traditional superhero stories, though in this case she still explored a different aspect of humanity. After a long space voyage, when she returned home she was forced to work at a fast food restaurant to pay her bills and made friends with a number of people in her “civilian identity.” This built up to the revelation of betrayal of her mother, and of Artemis taking over as Wonder Woman for a short time, but this was soon reversed. The following writer was John Byrne, who when he was writing Superman in the post-Crisis on Infinite Earths DC universe, had hinted at a relationship between Diana and Superman. This was explored occasionally under his run, but it is probably best known for the death of Diana, and the assumption of her duties by Hippolyta. She was soon returned to life (as she had never really died, instead having been deified). This period also introduced Cassandra Sandsmark, who would go on to become Wonder Girl at a later point. The remainder of this second series is best remembered for by the writing of Jimenez and Rucka, both of whom helped define the character. The latter during the lead-in of events to Infinite Crisis had Diana fighting Superman who was being controlled by Maxwell Lord. Battered after their battle, Diana has managed to stop Superman by using her lasso of truth on Lord, and the only option which she is given to stopping him is to kill him, and realizing this is the case, she does so. This created a controversy both within comics and in the real world, as both fans and characters alike debated the morality of this decision. In comics this also led to strained relations between her and Superman and her and Batman and with the addition of the events of Identity Crisis, helped to lead to the breakup of the Justice League of America at a crucial point right before the main events of Infinite Crisis were about to begin.
