Still puzzled as to Diana's identity, Bruce discovers more about her amongst the data he stole from Lex Luthor. He sees a photograph of her alongside the Wonder Men, taken in Belgium in 1918 during the closing days of World War I. He then makes contact with her via her laptop, sharing extra information that Luthor had on both her and other metahumans, such as the Flash, Aquaman, and Cyborg. Diana is visibly intrigued and shocked at this revelation, as Flash's lightning reminds her of that of Ares, Aquaman reminds her of depictions of Poseidon, while the Mother Box that created Cyborg reminds her of the one she briefly saw back on Themyscira. Diana resolves to take some time to think this revelation over, does not answer Bruce's e-mail, and instead proceeds with her plans to depart Metropolis on a flight back to France, through Turkey.
Wonder Woman gets a little jealous with Supergirl's arrival, believing she is trying to catch everyone's attention. When she realized that Supergirl is actually a better superhero because she looks up to Wonder Woman, they became friends and Wonder Woman helps to train Supergirl. She is among the heroes to battle against Granny Goodness and the Female Furies. She is voiced by Grey Griffin.

In addition, Diana appears to hold members of her close family in high esteem. In addition to the respect she has for her mother, Hippolyta, and aunt Antiope, she indicated that she held her father Zeus in the same very high esteem, when she was visibly angered when Lex Luthor referred to him distastefully while discussing the story of the Titan Prometheus.
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.
Unfortunately, not long after Diana left, Hera came for her vengeance, and though she could not bring herself to kill Hippolyta, she could not forgive her either. Feeling regret at giving up the only real family she had, Wonder Woman returned to Themyscira to find the Amazons absent, and her mother turned to stone. Shortly after, Wonder Woman encountered Lennox, a man who claimed to be another of Zeus' bastard children. After learning that Zeus has gone missing, they confronted the Gods of Olympus, Poseidon and Hades, in order to prevent them from taking over Zeus’ throne. To prevent a war between gods, Diana proposed that the two brothers share Heaven with one ruling during the day, and the other at night. Hera angrily interceded, which was what Diana had planned, and using Hermes' staff she transported herself to Mount Olympus to face Hera alone. She warned that she would make Hera regret what she had done to her mother before returning to Earth. Unfortunately, by the time she had returned, Hades had kidnapped Zola with the warning that Diana would need to make good on her bargain or Zola and her child would die.
