[Delmo Walters Jr.]

Remember Superman the animated series. There was an episode where he frees a woman from the phantom zone named Mala. When she learns about the powers she will get while on earth she is intrigued. after a while she is at full power and her arms are a bit muscular and she does a quick flex.

I took a frame grab of that shot, printed it, and had the actress who voiced Mala, Leslie Easterbrook, sign it at a con in 2005.
