Team Rocket HQ

The transmitter room

According to the Team Rocket Grunts found inside the HQ, it was once used as a ninja base, and was presumably renovated by Team Rocket sometime in the past.

The upper floor of the base contains Persian statues with security cameras in their eyes; walking past one triggers two Team Rocket Grunts that battle the player until they deactivate the cameras using a switch in the center of the area. The far left hallway bypasses most of the Persian cameras, but the floor is booby-trapped with Koffing, Voltorb, and Geodude, which battle the player and have a tendency to Selfdestruct. In Gold and Silver, the player cannot escape from these Pokémon.

The second floor contains the generator room where six Electrode power the radio transmitter. The room is locked and requires a password to open.

The third floor contains workstations, and a passage back onto the second floor leads to the rear of the HQ, where the main office is located. The office is also locked and requires two passwords to open.

All the Pokémon found on the trap floor know the move Selfdestruct and cannot be fled from in this generation.
