Etta

Giving us the benefit of her expertise in cartoons, crazycrone has uncovered Etta, a fat friend of Wonder Woman's, wearing a snug "band" outfit and freeing her friend from chains in the 1940s.
crazycrone says she was " a strange little chubby sprite, fuelled on sweeties, and skilled at incapacitating baddies..."

Here she is at her origins

And here she's doing fierce battle.

crazycrone adds:

"There was also the immortal Little Herbie Popnecker, if boys are allowed. He was sort of late 50's, and had surreal adventures involving sucking on various types of magic lolipops. His macho father would always be complaining about what a fat lump he was, but Herbie had actually been off saving the universe all day,etc."
