I wanted to add a young Japanese or Japanese-American whose mother had been at Hiroshima or Nagasaki, as a corresponding character to the X-Men, whose parents were, at that time, assumed to have been at the Manhattan Project. Stan (X-Men editor/co-creator ) didn't give me any good reason (rejecting the character ) - he just didn't want to, I think... I didn't bring it up again, but when I came back to the book, with Neal Adams, I created Sunfire, who is pretty much the character I had wanted to do some years earlier. I didn't make him an X-Man right away. By that time, Stan gave me a little more free . In fact, he was included in ''Giant Size X-Men'' #1, along with Banshee, precisely because I had gone around creating some 'international mutants,' with the goal of expanding the team at some time. I thought the X-Men shouldn't all be white Americans.
