One SF episode was when a radioactive meteor lands and makes things grow. Eventually Wonder Woman got too close and got turned into a giant she-hulk clone. Yummm! The other one was the Amy Zonn episode. Some female scientist thinks women are being discriminated against and makes some formula that grows her into a giantess. Double yummm!
The Plasticman one also involved a radioactive meteor. It ends up turning Penny into a giantess.
Yeah, I remember those cartoons from the late '70s - early '80s. I believe the Plastic Man episode was called "Mr. Meteor". The man who had the meteor turned into a muscular giant but unfortunately didn't do the same for Penny.
The episode with Wonder Woman growing also affected the Wonder Twins. The female Wonder Twin, Janna, almost grew as large as WW. Two female muscular giants in one episode has never happened before, has it?
My own particular fantasy started with the Hanna-Barbara cartoon show, Sinbad Jr. He pulled the strap on his magic belt to before very muscular and strong. One episode, "Rainmaker Faker", reportedly had a female using his belt to grow big and strong. I remember watching that episode as a kid but I cannot remember if that was the name of it or not. I have it on film but do not have a 16mm player to watch it. I tried it on an 8mm editor but it makes for very sketchy viewing.
