Today, I decided to take a look at some of the women who have donned the Helm of Fate.
First we have Linda Strauss
I believe she was the first female Dr. Fate. She was the step-mother of Eric Strauss who was chosen by Nabu to be the next Dr. Fate. However, Kent Nelson figured out that Dr. Fate was never supposed to be one person, but rather a combination of male and female energy. After Eric's death at the hands of Darkseid, she was the lone Dr. Fate for a very short period of time.
Next in line was Inza Nelson, Kent Nelson's long time wife and companion.
After returning from the realm of the dead, Inza took over as Dr. Fate after Eric and Linda's stint as the famed Lord of Order. Eventually the Helm was passed back to her husband Kent who then became Dr. Fate once more.
Black Alice wore the Helm on two separate occasions, but both were very brief.
Zatanna donned the Helm of Fate for one episode of the Young Justice show on Cartoon Network
I apologize if I have forgotten other female versions of Dr. Fate, but that is all that I can think of for the moment.
