I am currently writing an article for Alter Ego Magazine about the female Captain Marvels; Monica Rambeau, Jerry Ordway's Mary Batson/Bromfield, Phyla-Vell, and Carol Danvers (in the "House of M").
One thing I have noticed, is that each one of them have gone by at least two other superhero or villain names, and that some of them spent the briefest parts of their career as Captain Marvels.
I won't say too much more about them here now, watch for the issue coming out in December.
If your local comic book shop does not carry the magazine, you can order Alter Ego from TwoMorrows Publishing at http://twomorrows.com/. You can find my previous article for the magazine, comparing and contrasting Billy Batson/Captain Marvel with Rick Jones/Mar-Vell/Genis-Vell at http://twomorrows.com/index.php?main_page=product_info&cPath=98_55&products_id=728.
