When the rights to Daredevil reverted back to Marvel in 2013, most assumed that meant the rights to one of his main antagonists, Wilson Fisk, came along as a part of the package. However, a 2012 quote from Avi Arad, one of the producers of Sony's Marvel films, proves that's not the case. When asked by SuperHeroHype if Sony or Fox had the rights to the Fisk, better known as the Kingpin, Arad replied:
"Believe it or not, Kingpin was on loan to Daredevil, so again, anything that is part of the Spider-Man Universe or introduced in the Spider-Man Universe--without getting too legal beagle here--is an opportunity, and if we have a story that Kingpin is important, I'm sure we can handle that."
Very recently, in an interview with IGN, Feige said of the rights to the Kingpin,"Kingpin we either have or somehow share. I'm not 100 percent clear on that one." With a Daredevil series forthcoming in 2015 from Netflix, perhaps Sony, who does have a good working relationship with Marvel Studios, will be willing to work out a deal to allow the Kingpin to enter the MCU.
