Character fame is determined more on popularity than opinion, but not entirely fact. The Joker is a well known villain and criminal, as he is even known in other countries and continents. If Batman was used, it doesn't mean Joker will never appear, but he just won't be in one when Batman was just in one this season. There isn't proof that they can't use characters from a fictional universe whose characters have been in one, like using Harry Potter or Yoda. To me, I think it depends on how big the franchise is to determine whether or not it could have a different character from that universe in another ERB, but not one too closely related to the one already used (like Darth Maul or something).
