During Civil War, Carol gave her old Ms Marvel costume to Ultragirl, so it seems like she would have been a better successor as the new Ms Marvel, than this girl.

@degalon: Well, as far as I know, Ultragirl is now "retired", last time I saw her, she was working as a baby-sitter for Cage&Jones :) so she dosen't "use" the name of Ms. Marvel

On the other side, Kamala dosen't receive her name/title from Carol Danvers, she take it by themselve.

Perhaps one day, Tzu-Zanna will return to superheroine life with the title of Ms. Marvel, finding that Kamala have already taken the name... so... "Battle for the Cowl"? :P Maybe funny :)

Anyway, "Marvel" title have already caused this type of fight with legacy: Monica Rembeau and Genis-Vell fought for the title of Captain Marvel [and after, they re-match for the name of Photon!]

@degalon: ultragirl had her costume taken away during Dark Reign by Osborn. He gave it to moonstone.

I doubt many people care about Ultragirl
