Crown City

Crown City is an anime exclusive location that appeared in Zoroark: Master of Illusions. It is a fairly advanced city, but has greenery spread throughout.The guardians of the city are shiny versions of the legendary beasts and are said to only appear when the city is in trouble.

Years before, a disaster caused all of the greenery to die off and made the visiting Celebi leave. With the help of Pokémon, the people living in the city worked to regrow the plants. Although the greenery was restored, Celebi had not returned until the Ash and his friends visited the city.
