WARNING: The following contains spoilers for Wonder Woman #755 by Steve Orlando, Jesus Merino, Vicente Cifuentes, Romulo Fajardo Jr. and Pat Brosseau, available now.
Besides being members of the Justice League, Batman and Wonder Woman don't have much in common. Until recently, there hasn't been a reason to compare Diana’s and Bruce's personal lives -- but Wonder Woman #755 changes that with a rather unflattering comparison. Batman has a bad habit of molding sidekicks who get put in unnecessary danger -- and Diana may have done the same thing to Donna Troy.
In issue #755, Paula Van Gunther, aka Warmaster, accuses the Amazons of crimes against humanity. Warmaster and her forces also accuse Diana of personally manipulating Donna Troy and stripping her of her free will. Warmaster believes Diana has put Donna Troy in harm's way to further her own agenda.
Batman adopted a kid and transformed him into a crime-fighting sidekick, putting a young boy in danger. He also "mentored" 15 other young heroes, all of whom met with extreme hardship and violence due to their association with Batman. The most cruel connection was with Jason Todd, a young man who was brutally beaten and killed by the Joker. Batman's obsession with creating protegés has come under question by fans of the character.
On the surface, Diana's relationship with Donna seems different. After all, Donna is an adult. However, the potentially unethical nature of Wonder Woman's relationship with Donna Troy comes from the origin story of how Diana and Donna came to work together.
When Diana left Themyscira to join the Justice League, the island was subject to frequent attacks and diplomatic problems. Unfortunately, Diana Prince was busy being Wonder Woman and couldn't come back home to solve any of Themyscira's issues.
Donna was created out of clay as a replacement for Diana as a ruler. When she took control, she enacted a policy to murder Themyscira's colony of men and the Sons of Themyscira. When Diana finally returned to Themsycira to claim her throne, Donna Troy refused to relinquish power. Diana opposed Donna's plan to kill the men, but was called back to the Justice League for duty.
While Diana was gone, Donna led a group of Amazon warriors to kill the men of Themyscira. When Diana returned once more, she found the men dead and confronted Donna. Ultimately, Diana won and used her lasso of truth on Donna. Donna was horrified by what she had done and repented. Donna and the Amazons that killed the men were imprisoned, but Diana visited Donna frequently and gave her words of kindness and courage. Eventually, Donna was set free and went on to become a hero like Diana.
Donna and Diana's relationship is vastly different from Batman and his sidekicks, but there are similar themes. Both heroes have taken young protegés and molded them into crime fighters. The problem isn't so much that -- it's that these characters willingly endangered the lives of the inexperienced. Both Diana and Bruce have laid out paths for their sidekicks that could be deadly. Diana, of course, didn't adopt a young child and put them in harm's way. However, Donna's life is still being threatened because of Diana's actions.
