I've been thinking about this since I saw the Animated Movie years ago what would Diana do if she discovered her mother had a son that she tossed aside and even tried to kill? Like she was forced to have this son and didn't want to because she was told he'd become a nightmarish force of evil. Yet after being forced to have him she did raise but was abusive saying how men were evil and couldn't be trusted ultimately trying to kill him and leaving him for dead.
Then years later when Wonder Woman is away from the island this son returns after becoming a powerful sorcerer and warrior with an army of demons and gives Hippolyta a choice along the lines of "Acknowledge me as your son, Mother and I will leave this island in peace and never return and spare you and the Amazon's endless suffering." In a seen like this.
Then Hippolyta refuses to do this so he slaughter's half the amazon's and enslaves the rest.
Then through out the story arc the prophesy about how he was destined to become this evil terror is how Hippolyta justifies her treatment of him only for at the end it's pointed out that if Hippolyta hadn't have done the things she did to him the prophesy never would have come to pass.
How do you think Wonder Woman would react to such a situation and how would she handle such a enemy?
And what would you think of such a character being introduced to the Wonder Woman mythology?
