Yes, like I said earlier all the Marvel characters have met in the past. But, that doesn't mean BP is legally tied to them. For example, the punisher was first introduced in Spiderman. Yet, nobody considers him a Spiderman villain. He's his own solo character. With his own show coming up that Disney completely owns. The punisher is another potential character that can probably also appear in WDW. That's another topic for another thread.
This is why I'm asking if Disney can use BP in WDW.
