5. Blue Snowman
The Blue Snowman is a small town female teacher and scientist named Byrna Brilyant who disguises herself as a blue, snow-themed man to commit crimes. The disguise is a suit (initially made of clothing materials, but later more armoured), which doesn't really grant Byrna any superhuman powers as such, but which houses a "telescopic snow ray" that she uses to create petrifying blizzards which paralyse victims and a "defroster ray" to reverse the effect. She also has an army of robots that are attuned to her brainwaves which she uses to attack her foes. Her crimes are quite minor and petty, relatively speaking - such as attempting to steal diamonds - and there is nothing about the Blue Snowman that really puts Wonder Woman in any danger when encountering Byrna. The character would come across as a complete joke in a movie and shouldn't even be thought about when it comes to choosing live action villains for Wondy.
