Found exclusively in Pokémon FireRed and LeafGreen, this base is where one must travel to get the Sapphire gem. There are a few Grunts and executives within the compound that the player must defeat, in order to reclaim the Sapphire. There are also cages, in the back of the warehouse, presumably filled with stolen Pokémon. When one of the Rocket Admins is defeated, he sees Giovanni's Earth Badge, and realizes that all is lost for the Sevii branch, deciding to disband it. Before leaving, he vows to find Giovanni and rebuild Team Rocket. The stolen Pokémon then manage to escape.
The passwords for entrance into the Rocket Warehouse are "Goldeen need log" and "Yes, nah, Chansey," both of which are palindromes. The first password is obtained at the base of Mt. Ember from a Grunt and the second from Gideon in the Dotted Hole.
The Rocket Warehouse in the Pokémon Adventures manga
In the Pokémon Adventures manga
The Rocket Warehouse was first featured in Not Exactly Normal as the location where Sird and Carr retreated into after Red's battle with Deoxys on Five Island. Using the Unown she had released from the Tanoby Ruins, Sird was able to follow Deoxys's movements, further relaying the information to Giovanni at the Trainer Tower. While she was communicating with her Boss, Carr found a photo of a younger Giovanni holding a red-haired boy, leading Carr to realize that Giovanni wanted to use Deoxys's divination powers to locate his long-lost son.
Later during the FireRed & LeafGreen arc, Bill and Celio raided the Warehouse, recovering the Ruby and Sapphire that Team Rocket had positioned into an amplifier inside the building in order to replicate the climate of Hoenn in the surrounding area and thus allow Deoxys to access all of its four Formes. With the gemstones removed from the Warehouse, Deoxys lost its ability to change into its Normal and Speed Formes in the Kanto region, partially resulting in its defeat by Mewtwo aboard the Team Rocket airship.
The two passwords required to enter the Warehouse in the manga are "Examine the Exeggcute" and "Kibbitz with Kabuto"/"Execute Exeggcute" and "Oh crab, Kabuto".
Trivia
It is highly likely that this branch may be the precursor to the Johto branch that appeared threeyearslater, as one of the computer screens has plans for a device to force Pokémon to evolve. Such a device caused a rampage of Gyarados at the Lake of Rage during the plot of Gold, Silver, Crystal, HeartGold and SoulSilver. In addition, the Grunts vow to find Giovanni and rebuild Team Rocket, which is the goal of Team Rocket during the Generation II games and their remakes. The Rocket Admins, considering their teams, may in fact be Ariana and Archer.
If the player returns to the Warehouse after delivering the Sapphire to Celio, Gideon will ask them if Giovanni is their father. He immediately corrects himself, stating that Giovanni's son has red hair. The Fame Checker quotes him under the "Giovanni" section.
In the other localization languages the passwords are as follows: French: Tarsal la star and Ici Girafarig ici, German: Arbok Kobra and Makuhita Atihu kam, Italian: Un'ortica ad Articuno and Le scarpate di Parasect, Spanish: Aron ama a Nora and Ho-Oh es ese Ho-Oh.
