Cyclops is a great character. He’s evolved from the cookie cutter boy scout to a bona fide leader with complexities, willing to do whatever it takes to defend his cause. Hypothetically entertaining the idea that MvC4 is real and coming(which I still doubt), it will have to be some variation of his iconic self. I don’t think they’ll make him Phoenix Force Cyclops. That’ll probably just be a skin.
And that whole “Not putting in a deceased character in the game” is a farce. If they released a Marvel game since then, you really think they wouldn’t include Spiderman, Wolverine, Iron Man, or Hulk? They all died. It was just recently that they all came back. Unless you’d want their counter parts i.e Miles, X-23 or Daken, Iron Heart, and Amadeus Cho?
