Fan Casting Princess Diana in The Flashpoint DCEU (2018)

Diana is the princess of the Amazon. In the alternate timeline created by Flash, Diana became the queen of the Amazon instead of becoming a superhero and joining the Justice League. She and Aquaman formed an alliance between the Atlanteans and the Amazons, which resulted in a case. Aquaman's wife, Mera, discovered the case and nearly murdered the Amazon queen. Diana killed Mera in self-defense and took her crown as a warning against those who dare to try to kill her by starting World War III between the Amazons and the Atlanteans
