The last paragraph disagrees with what you (this group) has said:
"This is also seen in many American media, particularly involving Los Angeles. Entire books have been written on why fiction writers make Los Angeles a magnet for violence and natural disasters. Sometimes San Francisco. New York sometimes, especially in Marvel Comics (sometimes lampshaded that New Yorkers tend to be more used to superhero fighting than anyone else). These cities also share many similar traits with Tokyo. See Big Applesauce. Likewise, in British media London Is The Centre Of The Universe. Canadians who refer to Toronto as such, however, are being self-deprecatingly sarcastic (if they live in that area themselves) or just plain sarcastic (if they're from anywhere else in Canada)."
Should this be the jumping off point for a supertrope, and we'll make a subtrope for every big city in the world? (is very uncertain about that idea)
