Okay, if you don't know, early Wonder Woman stories were batcrap crazy. William Moulton Marston, Wondy's creator, was a huge bondage-fetishist pervert and plopped the Amazonian Avenger into so many situations where she got tied up it wasn't even funny. Oh, and he also gave her one of the lamest sidekicks of all time.
Etta Candy was introduced in the 1940s as a gigantic tub of lard who loved to eat sweets. That's it! She often saved Wonder Woman's bacon, and at one point single-handedly stormed a Nazi concentration camp with nothing but a box of candy for a weapon. Why exactly an indestructable Amazon with an invisible plane needed Beth Ditto to fight her battles was never explained.
The character has been sort of smoothed out over the intervening decades, and Etta is now a career Air Force intelligence officer with an eating disorder. Progress!
