It was the fall of 1985...I walked into editor Janice Race's office to find out about the fate of Diana Prince. I was curious to learn who was going to draw her. Superman had [John] Byrne and [Jerry] Ordway, Batman had [Frank] Miller and [Alan] Davis (and later [David] Mazzucchelli). Wonder Woman had...No one. A writer, Greg Potter, had been selected but no established artist wanted to handle the new series. After exhaustive searches, it seemed Wonder Woman would have to be assigned to an unknown...I thought of John Byrne and Superman. What a giant coup for DC. A top talent and fan-fave on their premier character..."Janice" I heard myself say "What if I took on Wonder Woman for the first six months – just to get her out of the starting gate?"
During a training session observed by Hippolyta, Diana sparred against her fellow warriors, demonstrating her weapons expertise and defeating each of them swiftly. Her final opponent was Antiope herself. The two fought with all their might. Diana managed to disarm Antiope and looked toward her mother for approval. Antiope seized the opportunity to push Diana to the ground and pick up her sword, admonishing her for letting her her guard down. As Antiope slashed at her and forced her backwards, Diana instinctively brought her arms together to block the attack. She clashed her arm gauntlets together, resulting in her unleashing a powerful shock-wave that sent Antiope flying back and left all spectating Amazons there, including Diana herself, in complete shock.
The American theme of Diana's costume was explained by Pérez in the Challenge of the Gods storyline in which Diana engaged in a series of trials arranged by Zeus as punishment for refusing his advances. Diana met the spirit of Steve Trevor's mother, Diana Trevor, who was clad in armor identical to her own. Trevor revealed that during World War II she had crashed on Themyscira while on duty as a U.S. Army pilot. She blundered into an Amazon battle against Cottus, a multi-armed demon, at the portal to the underworld. Trevor was drawn into the battle, although she was armed only with her side arm. She wounded the beast before suffering a mortal blow, allowing the Amazons to reseal the portal.
While not completely invulnerable, she is highly resistant to great amounts of concussive force and extreme temperatures and matches Superman in this regard. She is completely immune to his heat vision, virtually any damage, or even the core of the sun. However, edged weapons or projectiles applied with sufficient force are able to pierce her skin. Due to her divine origins, Diana can resist many forms of magical manipulation.
She later became a major character in the DC Animated Universe in Justice League and its sequel, Justice League Unlimited. Both shows were massively popular and helped bring Wonder Woman back to relevance for a younger generation. The DCAU is notable for introducing the idea of a romance between Batman and Wonder Woman, something that was unheard of in the original comic books. Throughout the DCAU, Wonder Woman was voiced by Susan Eisenberg.
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.
