Why do a majority of the super humans in a given world always congregate in large cities? And more importantly why do the super villains? It seems like a villain could make more money and be more successful in smaller less super human populated cities like Toledo Ohio, or Las Vegas New Mexico. Granted the bigger fish are caught in the deepest water so bigger cities would have more to offer a thief but if a criminal wanted to make out why not just hit the small towns?
One theory I’ve been kicking around is that cities are built along some sort of Ley line where super humans get more bang for their buck. The reason you don’t see many super humans in Amish country is because there just very much energy there to feed super powers. New York, LA, or Chicago would have a large concentration of super humans because they are also repositories of super human energy.
OR
Maybe superhuman create this power and the higher the concentration the more powerful all the superhuman as a whole become. So if all the super heroes decided to go live in Cedar city Utah that would become a super human nexus point. Super humans congregate with their own kind because they benefit from the amount of power in those areas.
Just something I’ve been kicking around.
