In Ruby, it is known as Magma Hideout instead. The base is essentially the same, though there is less water, all Aqua members are replaced by Magma members, and Matt is replaced by Tabitha.
On the inside, the player will find teleport platforms scattered about. There are also a number of Grunts to take on, including the team's admin Matt who will tell the player that Archie, the leader of Team Aqua, has left with the submarine to the watery depths near Sootopolis City.
After finishing everything in the Hideout, the player is free to move onto Route 124 which was previously blocked by a Grunt trying to train his Wailmer. Route 124 connects to Mossdeep City. In Sapphire, the entrance to the hideout is sealed after defeating Tate and Liza.
A colored background means that the Pokémon can be found in this location in the specified game. A white background with a colored letter means that the Pokémon cannot be found here.
Trainers with a PokéNav by their names will be registered in the Trainer's Eyes or Match Call function after the first battle, and may have a rematch with the player with higher-level Pokémon.

In Pokémon Adventures, the Aqua Hideout briefly makes an appearance in VS. Whiscash when Maxie and Tabitha are let in to join their resources with Team Aqua for the time being so that they reach the Seafloor Cavern safely. Many Grunts from both teams are also taken as backup.

Because the entrance is sealed after the defeat of Team Aqua in Sapphire and the defeat of Team Magma in Ruby, if the player does not obtain the Master Ball here before that, they cannot get the Master Ball without winning the Lilycove Department StorePokémon Lottery Corner or trading one in. This was fixed in Emerald, as the hideouts remain open even after Team Aqua and Magma are defeated.
