Metro City is Astro Boy's place of residence in the 2003 series and 2009 CGI film.
The city is portrayed as futuristic and way ahead of its neighbors in terms of robotics. It is based on modern day Tokyo, and is seen in almost every single episode. A vast, expanding metropolis, it is a typical city: with crooks, robots, policemen, and ordinary people. It is home to the ministry of science, a marine park, and metromusements theme park. The mayor of the city is Chairman Lyon. According to Inspector Tawashi, about ten million people live there.
2009 film[]
Metro City looked completely different in the 2009 CGI film. In the film, it is a large hovering airship, floating high above the air with futuristic buildings and where humans and robots co-exist. It is a place where only the rich and wealthy live, the others still live on the surface of the Earth. Its leader, President Stone, was a greedy and evil man. He was presumably replaced by a new President following his actions as the Peacekeeper.
