Pokémon G/S Walkthrough - Chapter 16

Saffron City

TM 29 - Psychic

Once in Saffron, there is a man named Mr. Psychic. Talk to him and he'll give you the Psychic TM.

Focus Band

Right next to the Saffron City Gym is the Dojo. The only thing interesting in here is the Pokéball containing Focus Band. The Focus Band may prevent fainting.

Saffron City Gym - Sabrina

The Saffron City Gym still has that teleporter puzzle that you must get through. Keep going to the right or left and you'll eventually get to Sabrina after battling a couple Psychic Trainers along the way. Sabrina's Psychic Pokémon are not too difficult to beat. If you have a strong Electric Pokémon a couple strong Electric attacks to take out her Pokémon. Strangely enough, Sabrina has a female Mr. Mime in her lineup. Apparently the English translation to "Mr. Mime" wasn't a good idea because its Japanese name does not have to deal with a gender. After you beat Sabrina grab her Marsh Badge and teleport your way out of there.
