It seems many people are saddened that their favorite characters can't do a crossover, say Spider-Man in the Avengers and such. But many character move around quite a bit. Here's what I mean: Wolverine first appeared in a Hulk comic and is also an official Avenger. Kingpin first appeared with Spidey but first came to the big screen in DD. Panther first appeared in Fantastic four before becoming an Avenger. There are lot's of other situations like this, so here's my question. When a company secures the right to use a character does Marvel give them a big lists of characters or does the company have to ask for specific characters? Is Spider-Man and Daredevil owned by the same company? If not Sony could sue because of the Kingpin, who is one of Spidey's buddies. I'd love to see Kraven take on the Panther, could it happen?
