“When you’re doing comics, you need a visual shorthand in order to convey certain aspects of a character,” Ostrander says, “and if Amanda Waller’s nickname was ‘The Wall,’ she had to look a little bit like a wall. She had to look formidable. By not giving her Wonder Woman’s muscles, and instead some heft, it sort of suggested a power in her.” - vulture.com
