To me the reboot could have been a nice chance to reintroduce some of wonder woman enemies that haven't been seen in a while or new origins.
1.Priscilla Rich: Owned a statue that hold the Cheetah goddess. When Priscilla developed the split personality the Goddess take her chance and would appear to Priscilla in her mirror.
Giganta: To me there could be 3 ways to write Giganta
1.Giganta come from a Tribal village. She was cursed as a child for a crime or it could be a gift.
2. She was a goddess herself but was hated and kicked out.
3.Giganta came from a group of gods that are non existed since people no longer believe in them. Seeing how people were losing faith in them, Giganta's mother appear as a mortal and slept with a man.
Hypnota: Maybe she could have been born with this gift and the reason why she dressed like a man was because she came from a patriarchy society , so her mother dressed her up like a boy so she could get better things. She would late learn stage tricks to trick people and make them her slave or sell them to Evilness
Baroness von Gunther: She could easily be depiction as a leader of a hate group but like in the golden age she would become wonder woman's great ally.
Blue Snowman: Was a great teacher but when the school board cut the budget, she used her father suit and demand they give more money and drop the sexist classes. The more times she did it the more money drove she become and went mad.
Queen Clea: Reason why she sent her army(which were all women) to war so many times was to never become like her mother, who allowed a man to rule when men were weak and useless in their nation. She want to prove to people women were strong and did by force and would take over other nations.
What villains would you want to see return? There are probably silly ideas.
