I just had one with respect to Ah! Megamisama! (Ah! My Goddess) and Belldandy, the lovely, warm-hearted goddess with awe-inspiring flowing hair. I now know why I had an instinctively positive reaction to her, and who she reminded me of.
Belldandy is a modern version of the O'Neill pictures of Polychrome, the Daughter of the Rainbow, from the Oz books by L. Frank Baum. Polychrome was my first real total crush on a fictional character. Now I'll always think of her with Bell-chan's voice, too.
