When Hippolyta and the other Amazons were trapped in a demonic dimension, she started receiving visions about the death of Wonder Woman. Fearing her daughter's death, Hippolyta created a false claim that Diana was not worthy of continuing her role as Wonder Woman, and arranged for a contest to determine who would be the new Wonder Woman, thus protecting Diana from her supposed fate. The participants of the final round were Diana and Artemis, and with the help of some mystic manipulation by Hippolyta, Artemis won the contest. Thus, Diana was forced to hand over her title and costume to Artemis, who became the new Wonder Woman and Diana started fighting crime in an alternate costume. Artemis later died in battle with the White Magician – thus, Hippolyta's vision of a dying Wonder Woman did come true, albeit not of Diana as Wonder Woman. Diana once again became Wonder Woman, a request made by Artemis in her last seconds. Artemis would later return as Requiem. Prior to Artemis' death, Hippolyta would admit to her daughter about her own part in Artemis' death, which strained their relationship as Diana was unable to forgive her mother for sending another Amazon to her death knowingly for the sake of saving her own daughter.

Impressed by this unknown woman's self-sacrifice, the Amazons entombed her with honors and clothed her in armor displaying the American flag pattern on her uniform, which they assumed were her heraldic colors.
