But you do have to look strong if you're raised in a warrior society where physical strength is a core value.
Wonder Woman should look more substantial than a fashion model no matter where her strength comes from.
Why?
Women are all different shapes and sizes.
All amazons are trained to be warriors despite being all different shapes and sizes.
Wonder Woman could have been a half pint fattie, but because her strength comes from magic, she can still throw Superman at the moon, despite having Rosie O'Donnel's figure (who was gorgeous as Betty Rubble, but that was a long time ago, and a trick.).
Logically the stronger they are because of magic, the ability to effortlessly juggle elephants, the harder it is to get/make muscles, since muscles come from exertion and breaking through barriers during exercise, so the body of a model is about right if they literally can't exercise.
You remember that Linda Carter won the Miss World America pageant right?
(She got to the semi finals in the Miss World pageant representing America.)
I was reading a Wonder Woman comic the other day, and I noticed something bizarre. After the universal reboot of the comics "recently", Etta Candy is "currently" African American and not a lot like Lucy Davis pigmentally. Lets wait and see if the internet freaks out like it did with Michael B Jordan playing the Human Torch?
