The secret identity of the masked thunder goddess was the most tantalizing secret in superhero comics for a few months. When it was revealed that Thors ex-girlfriend Jane Foster was the new hammer-thrower, the drama got even deeper. Jane was shown to be fighting cancer in a previous Thor series and her struggle against her bodys malignant cells continued even after she picked up the hammer. Every moment she wasnt being a superhero, she was dying from a disease thats killed millions.
Thanks. I really enjoyed that. Comic art on that link is great.
