Since they don't have an iconic female character like WW (well, at least as old as WW), maybe with the Phoenix being the most popular from X-men, so their best bet is to recreate one.
Do you think DC should create a new superhero or gloss up an existing one that has the potential to rival Capt. Marvel for the much younger generation, like Supergirl?
I often Wonder Woman will be still as popular once its main demographics are no longer in this planet, and if it will follow the likes of Zorro and other superheroes or famous characters that many people now don't even remember.
