The mystical city where history slumbers. (Japanese: れきしが ねむる しんぴの まちThe mystical city where history slumbers.)
Sootopolis City is located inside of a giant crater.
In Pokémon Ruby, Sapphire, and Emerald, the crater is that of an underwater volcano which erupted and forced itself out of the sea many years ago, eventually filling with rainwater.
In Pokémon Omega Ruby and Alpha Sapphire, the crater was formed by a giant meteorite impact into the ocean of the Hoenn region thousands of years ago, eventually filling with rainwater. People soon began to dwell in the crater for its warm, fresh water and a city soon came forth. The great tree in front of the Cave of Origin was received from AZ when he visited from the Kalos region.
To navigate the city, people have to climb many flights of stairs and Dive under the sea. This causes many of the locals to get into good shape.

In the house northeast of the Pokémon Center, there are two brothers who are arguing over two different species of Pokémon. The younger brother is a Fisherman, while the older brother is a Hiker.
In Pokémon Ruby, Sapphire, and Emerald, they are arguing over the sizes of their favorite Pokémon. If a brother is shown a Pokémon of the species he prefers, he will calculate its size and give the player a prize if it is bigger than the largest one he had seen before; the younger brother gives an Ether, while the older brother gives an Elixir.
In Pokémon Omega Ruby and Alpha Sapphire, they are arguing over the cuteness of their favorite Pokémon. If a brother is shown a Pokémon of the species he prefers with an Affection of at least level 4, he will give the player a Max Elixir.
In Pokémon Ruby, Sapphire, Omega Ruby, and Alpha Sapphire, the younger brother prefers Barboach and the older brother prefers Shroomish. In Pokémon Emerald, the younger brother prefers Seedot and the older brother prefers Lotad, and the initial record size is 0.5 meters.
In Omega Ruby and Alpha Sapphire, in the north-eastern part of Sootopolis City there is a house with an elderly gentleman within it. If the player talks to him with a Dragon-type Pokémon with high friendship, he will offer to teach it Draco Meteor.

Sootopolis City reappeared in the Omega Ruby & Alpha Sapphire chapter, where Zinnia was taken there after Rayquaza rejected her offer to join her in order to destroy the meteoroid headed for Hoenn. Upon Emerald's request, Zinnia agrees to work alongside the Stones, Joseph and Steven, for a solution to avert the impending apocalypse. Eventually a plan was devised, which involved the Hoenn Gym Leaders, Elite Four, and Frontier Brains, as well as the Draconids, Red, and Green, all standing by at Sootopolis to launch a combined attack towards the meteoroid, while Ruby and Sapphire would ride Rayquaza into space to strike the meteoroid directly.
In the flower patch next to the big tree AZ gave, there is a flower in the patch that is the same in design to the flower the Eternal Flower Floette, the Floette that befriended AZ in the Pokémon X and Y storyline.
This is the only city in the Pokémon world which requires the use of Dive in order to be reached for the first time.
