In Wonder Woman Vol. 1 #204, Diana's powers and costume were returned to her and she is once again reinstated as Wonder Woman. I-Ching is killed by a crazy sniper in the same issue. Later, Diana meets her sister Nubia, who is Hippolyta's daughter fashioned out of dark clay (hence Nubia's dark complexion). Nubia claimed to be the "Wonder Woman of The Floating Island", and she challenges Diana to a duel which ends in a draw. Returning to her home, Nubia would have further adventures involving Diana.
In 1954, Dr. Fredric Wertham alleged that there were lesbian subtexts to Wonder Woman and claimed comics contributed to juvenile delinquency in his book Seduction of the Innocent where despite a very obvious heterosexual relationship with Steve Trevor, Wertham asserted that Wonder Woman’s association with the Holliday Girls could be interpreted as a lesbian relationship. The Comics Code Authority was then introduced in reaction to Wertham 's claims against the entire industry.
During the Silver Age, under writer Robert Kanigher, Wonder Woman's origin was revamped, 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."
For a time she was given enhanced vision by Athena, which gave her the ability to see in darkness and through illusions. This also makes her resistant/immune to telepathy. Due to her wisdom she can learn languages faster than a regular person, she can talk to animals. She has also been shown to project herself astrally in order to commune with the gods and ask for special favors from them. She has also been shown to take on the abilities of certain of her patron goddesses as when she became a form of divine midwife to save the life of an unborn child.
Various Wonder Woman enemies would debut in the comic series. Issue #1 introduced Wonder Woman's nemesis, Ares, as the embodiment of all abnormal emotions, evil, and essentially all that Wonder Woman was against. Issue #5, the character of Doctor Psycho, a murderous psychopath with an intense hatred of women, was debuted, Issue #6 introduced Cheetah while issue #9 introduced Giganta. Also Issue #9 debuted Queen Clea, which would later help form the female supervillain team, Villainy Inc.. Later on Issue #49 debuted another recurring enemy, Circe.
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.
The Silver Age format for comic books also did not generally favour a lot of story arcs, or at least, not memorable ones. In this period though the character did undergo some consistent changes as she battled a variety of common foes including Kobra, but the changed format gave her the ability to develop more as a character. The silver age stories of Wonder Woman can be broken into a few general arcs – the depowered stories (in the mod girl phase), undergoing tests to re-enter the Justice League of America, a golden age story about her work during the Second World War, her adventures as an astronaut for NASA, the hunt for Kobra, and eventually the return of Steve Trevor and the internal politics of working at the Pentagon. The most famous story which she was involved with at this time was “For the Man Who Has Everything”, a story focused on Superman, but also involving herself and Batman. The first major story arc which she was part of was Crisis on Infinite Earths, which also ended her silver age appearances.
