I don't think there was a plan for a JLD lineup and Zatanna was intentionally left out. It just seems telling they made figures for the male characters but not the one female. And that seems to be par for the course for McFarlane. And I'm not buying that female characters don't sell. But I admit, I could be wrong.
I've got plenty of Zee figures, so I'm not losing any sleep over it. I'd probably buy one though if they made one.
