Frank Miller has said that "Metropolis is New York in the daytime; Gotham City is New York at night." Gotham City is home to Batman, whose activities are more often nocturnal, while Metropolis is home to Superman, who usually operates during the day. In terms of atmosphere, "Batman" writer and editor Dennis O'Neil has said that, figuratively, "Batman's Gotham City is Manhattan below 14th Street at eleven minutes past midnight on the coldest night in November, and Metropolis is Manhattan between 14th and 100th Streets on the brightest, sunniest July day of the year. New York City has been more recently used as a locale in the DC Universe, like the Marvel Universe, in which it exists as a separate city from Metropolis and Gotham City. The Justice Society of America, for example, is based in New York, as were the Teen Titans.
