Most characters they did it with were either minor characters in comics who barely anyone cared about or it didn't matter. With Kang his skin colour doesn't matter since most of the time he wears that blue mask thing on his face in the comics.
@GothamRockstar Because it's simply doesn't matter what his skin color was. Kang is just like 75% of Marvel characters isn't based on his race, he is based on his personality.
@VaranKing Bruh "option"... Really now? Is this how people feel when I typed lol?
@IronWidowMaikuB His MCU counterpart is still kinda crappy to me though, compared to his EMH Iteration. Still, I wanted to see more of him in the movies before Majors got fired.
