Given this isn't even the "real" Spiderman, how is this any more groundbreaking than when Spiderman 2099 turned out to be Hispanic?
Or when John Stewart got a GL power ring?
Or John Henry Irons wore the Superman symbol?
Or they put Jim Rhodes in the Iron Man armor?
And let's not forget the black Capt. America in Truth, the black female Captain Marvel and, of course, black Ultimate Nick Fury.
