Immortality: Wonder Woman, due to being an Amazon, has lived for millennia without visibly aging, with her being roughly 5000 years old (having been born right after the War of the Gods), and having been present in the "Man's World" since World War I. She is thus the oldest member of the Justice League by far (though still roughly a millenia younger than Enchantress, and even more so than Ares and Steppenwolf), making her an ageless immortal, much like Superman.
Pérez and Potter wrote Wonder Woman as a feminist character, and Pérez's research into Greek mythology provided Wonder Woman's world with depth and verisimilitude missing from her previous incarnation. The incorporation of Greek gods and sharply characterized villains added a richness to Wonder Woman's Amazon heritage and set her apart from other DC heroes.
Diana and Trevor arrived at the British War Council's meeting place. Trevor told her to stay behind while he retrieved one of his superiors from the war room. Curious, she followed him into the room, where dozens of men argued with each other while Sir Patrick Morgan struggled to be heard. The room fell silent as the men noticed Diana, as women were not allowed in the room; Trevor quickly escorted her out.
When last we left Wonder Woman #49, the battle brewing ever since DC's METAL cracked open the Multiverse seemed to be reaching its climax. With the Dark Gods playing similar roles to the Greek pantheon, but with all-powerful demands, enslaving humanity, Diana and her twin brother Jason were splitting up to oppose them around the globe. Just as they seemed to knock back their leader, King Best, the Dark Gods launch an assault on Jason.
