Would you prefer some "legacy characters" in comic books to have one consistent character incarnation? For example, one Flash, one Robin, one Clayface, one Earth. It's just because I was wondering how most non-comic fans only seem to know of Dick Grayson as Robin, and I've personally lost track of who was Clayface past the first two, and all the Earths (but, I guess, it's not surprising, when some of these characters have been around for over 70 years).
