Yeh, but until DC changes its polices, it's unlikely the big DC names will ever be able to appear in live action TV, outside of cameos or prequels (like Smallville or Gotham).

I get that, they need a larger roster to fill a whole season with villains of the week. But that doesn't change the fact that there have been some blatant Superman exclusive plots, like "For the Man Who Has Everything".
