United States of America

The United States of America is a country on Earth. Mario and Luigi's hometown of Brooklyn is located here.

In several episodes of The Adventures of Super Mario Bros. 3, various locations in America were travelled to. Those include Brooklyn, Washington, D.C., Hawaii, Hollywood, New York City, Kansas and Florida.

In "Reptiles in the Rose Garden", Bowser and Kootie Pie Koopa took over America by travelling to Washington, D.C. and abducting the President by warping the White House to Dark Land. Until the President's return, Bowser made Kootie Pie "Empress of America".
