A while back, Spider-Man movie producer Avi Arad said that the Kingpin was a character they could use in the Spidey movies. This caused some people to worry that the big Daredevil villain could be left out of the upcoming Netflix series. Apparently that won’t be the case as it sounds like the character is another shared one like Scarlet Witch and Quicksilver are.
Kevin Feige explained to IGN the situation:
IGN: Can you shed any light on the nature of the rights for characters like Namor and Kingpin and Elektra? Clearly, with the Daredevil Netflix series, a lot of people are wondering who basically controls Kingpin and Elektra, and a lot of folks are wondering about Namor because of the fact that you guys are going to do The Defenders. Can you clarify that situation?
Feige: No, Namor I think is a little complicated, the way some of them are. Elektra I think we have. I think that was part of Daredevil, and that’s clean and simple. Kingpin we either have or somehow share. I’m not 100 percent clear on that one.
At last count, Universal owned Namor. Although that could’ve changed recently which is why he’s saying it’s complicated (he’s technically a Mutant).
