While a visibly shell-shocked and saddened Batman promptly retrieves Superman's lifeless body (enveloping him in his own cape), Wonder Woman takes the body from Batman, gently placing it on the ground before them. Lois proceeds to cradle and weep over her fallen beloved, as Wonder Woman and Batman stand next to her in respectful lamenting silence. Wonder Woman equally saddened at his death, due to now not having the chance to get to know Superman.
Despite helping win the war, defeating Ares and still loving humanity, Diana is still left sobered, emotionally broken, psychologically scarred, and devastated over not having been able to save the Belgian village from Dr. Poison, as well as over her beloved Steve Trevor's self-sacrificing death. Indeed, Diana would later claim that she "would never be the same" ever again after World War I. Moreover, in the years that followed, Diana bore witness to a "century of horrors" (Wars, Fascism, Communism, nuclear weapons' deployment, geopolitical brinkmanship, racism, homophobia, genocides, war crimes, propaganda, and etc.), and due to all of this occurring without Ares being there to spread corruption, Diana almost completely lost faith in humanity, coming to believe that humans "made a world where standing together is impossible". As such, Diana resolved to mostly abandon superheroism for 100 years.
As the men helped the Amazons prepare for battle against the First Born's army, Diana received news that the First Born had been attacking other gods' realms. With Eros and Artemis, Wonder Woman ambushed the Minotaur at Demeter's home. Unfortunately, the First Born had already defeated Demeter, so Wonder Woman sent her companions to safety while she confronted him by herself.
