Re: Do you think the Red Skull will return?
Red Skull was kind of a James Bond villain, where as I think a lot of people wanted him to be Bane or Jokeresque.
I would definitely like to see a darker side to the Red Skull in the future, but I don't think a grim dark take on Skull would've fit the tone of the film, nor the MCU.
