In the second issue of Sensation Comics (December 1941), Wonder Woman gets her first villain, Doctor Poison, in this incarnation a Japanese princess named Maru who works for the Nazis.
To help defeat Doctor Poison, Wonder Woman enlists another supporting character introduced in this issue of Etta Candy.
Bad puns aside, I’m a bit fascinated by Etta. While Wonder Woman is a super-powered ideal, she still pines after Steve in kind of pathetic ways. On the other hand, Etta is un-apologetically, erm, big-boned in a medium where every other female character is consistently curvy and glamorous. In addition, Etta has an infectious gung-ho attitude and is a natural leader of women. It seems almost like they were going with comic relief, but they found something else.
