Saffron City is a sprawling metropolis located in the heart of the region between Cerulean City, Celadon City, Lavender Town, and Vermilion City. The Silph Co. headquarters dominates the city skyline, and two Pokémon Gyms stand in the northeast district. It is the most populous city in all of Kanto.

Mr. Psychic's house

The southeast house belongs to a man known as Mr. Psychic. Speak to him and he claims to know exactly why you are here, and gives you TM29 (Psychic).

Silph Co.

The Silph Co. is the leading manufacturer of items like Poké Balls, Potions, and TMs. Their products are supplied to every Poké Mart in the region. The company has been a target of Team Rocket, first for their Silph Scope prototype, and now for a top-secret development project. The Rocket Grunt posted outside the building has fallen asleep, leaving a perfect opportunity to sneak inside. The building holds eleven floors, with warp tiles allowing the workers to quickly move around. This convenience ends up acting as a maze for anyone trying to reach the top floor.

Rival Battle 6

Blue has made some changes to his team since the previous battle in Pokémon Tower. He has swapped out his Fearow for a Kadabra, while his Shellder, Magnemite, Vulpix, and Eevee have all evolved.

If Eevee evolved into Vaporeon:

Afterward, he brags that he will be the world's most powerful Trainer before warping away. Once he leaves, speak to the nearby office worker. Realizing that you are here to save them all, he would like to give you a Pokémon. If you have room in your party, he gives you a Lapras. They had been keeping it in their lab, but he thinks it would be much better off with you. Take the final warp tile to the west side of 11F.

11F (West)

As soon as you move off of the warp tile, you are confronted by Jessie and James again. They claim that their boss is in a meeting and intend to defeat you so that he will not be disturbed.

Rocket Silph Co. Yellow Reward: $930 Type: Poison Unknown Weezing Lv.31 Tackle Normal   --       Smog Poison   --       Sludge Poison   --       Struggle Normal   --       Type: Poison Unknown Arbok Lv.31 Bite Normal   --       Leer Normal   --       Poison Sting Poison   --       Glare Normal   --       Type: Normal Unknown Meowth Lv.31 Growl Normal   --       Bite Normal   --       Pay Day Normal   --       Screech Normal   --

Use the Card Key to open the door and confront Giovanni. He claims to be having some important business meeting with the company president and warns you to stay out of grown-up matters before drawing you into battle.

VS Giovanni

Giovanni's Nidorino, Rhyhorn, and Nidoqueen all take serious damage from Ground-type attacks like Dig and Earthquake. The latter two are also vulnerable to Water moves. His Persian only takes super effective damage from Fighting attacks.

Giovanni Silph Co. Yellow Reward: $4059 Type: Poison Unknown Nidorino Lv.37 Double Kick Fighting   --       Poison Sting Poison   --       Focus Energy Normal   --       Fury Attack Normal   --       Types: Ground Rock Rhyhorn Lv.37 Horn Attack Normal   --       Stomp Normal   --       Tail Whip Normal   --       Struggle Normal   --       Type: Normal Unknown Persian Lv.35 Scratch Normal   --       Growl Normal   --       Bite Normal   --       Pay Day Normal   --       Types: Poison Ground Nidoqueen Lv.41 Scratch Normal   --       Tail Whip Normal   --       Body Slam Normal   --       Double Kick Fighting   --

With Giovanni defeated, Team Rocket's plans for Silph Co. have been thwarted. He vows that the group will never fall and promises to return. Giovanni and his underlings make their escape, while their co-conspirators also flee the building. Speak to the president, who is so grateful to you for saving Silph that he rewards you with the Master Ball prototype. This improved kind of Poké Ball has a 100% success rate, so be sure to save it for a hard-to-catch Pokémon.

Copycat's house

Now that the Rockets have left the city, the Grunt outside the northwest house is gone. A girl inside known as the Copycat likes to collect Pokémon dolls. Give her a Poké Doll to receive TM31 (Mimic) in return.

Fighting Dojo

Fighting Dojo

Saffron City is unique as the only city to have two Pokémon Gyms. The Fighting Dojo is located in the northeast neighborhood, next door to the Saffron Gym. The two clubs had once competed to determine which would become the city's one official Gym, and the Psychic Pokémon of Saffron Gym were victorious. There is no Badge to be won here, but defeat the Karate Master to earn the choice of two rare Fighting-type Pokémon: the hard-kicking Hitmonlee or the piston-punching Hitmonchan. Use Psychic- and Flying-type attacks here for greatest effect.

Saffron Gym

Saffron Gym

SAFFRON CITY POKéMON GYM
LEADER: SABRINA
The Master of
Psychic Pokémon!

The Saffron Gym specializes in Psychic Pokémon. Only Bug attacks deal super effective damage to them, but the few available Bug moves are relatively weak. Psychic Pokémon typically have low Defense, so it is better to use moves that deal physical damage, like Normal-, Flying-, and Rock-type attacks.

The Gym uses a series of warp tiles to confuse and disorient any challengers. Step on the tile near the entrance to reach the southeast room. To reach the Gym Leader by using as few warps as possible, continue by stepping on the northwest, southwest, and southwest tiles in the following rooms. This leads to the center room, where Sabrina awaits anyone up to the challenge.

After the battle, Sabrina awards you the Marsh Badge, which ensures obedience from all Pokémon up to level 70. She also gives you TM46 (Psywave) as a prize.

The next destination is Fuchsia City to the south. There are two paths that lead there: either take Cycling Road west of Celadon City, or follow the coast south of Lavender Town.
