It had been assumed that the star of his current miniseries was Helena Bertinelli, the post-Crisis version of the character.
Following the announcement of World's Finest - one of the six new titles to replace the first cancellations in the New 52 line - Levitz has revealed that the character is actually Helena Wayne, the daughter of an alternate version of Batman and Catwoman.
The new series follows Huntress and Power Girl, two refugees from the soon-to-be-revived parallel universe Earth-2, as they struggle to return home from the main DC continuity.
"The first scene in the first issue is basically kind of a Sex in the City moment of the two girls at lunch, at a posh place that turns out to be in Tokyo, and Helena's busy burning her Helena Bertinelli passport and playing with a deck of five or six other passports she's got in other names, trying to decide who she's going to be next," Levitz told Newsarama.
"We will ultimately know that she's Helena Wayne of Earth-2, but whether Bruce will know that she's Helena Wayne, or how Bruce or Selina Kyle will come to know that and react to that, we'll see. I'm still working out all the dramatic potential in it."
Earth-2 was introduced in the 1960s as a parallel world where classic characters including Batman and Superman continued to age and were replaced as superheroes by their children and successors.
Power Girl is the Earth-2 version of Supergirl.
The concluding Huntress #5 will be released on February 8.
