Catwoman/Gordon likely get more screen time then Johnny storm in any of the movies and the story defiantly revolves around CW more then it did Jonny in any of the FF movies so if you want to say they don’t count as main characters Johnny obviously shouldn’t either so what’s the problem?
How is it that one Johnny managed to single handily FF with his race change but Gordon cat woman and who knows how many other characters in other movies doesn’t effect them at all?
