Pokémon Red and Blue/Saffron City

'Saffron City is home to the Silph Company, the makers of the fabulous Silph Scope. So how did Giovanni get his paws on the Silph Scope prototype? Is the company in cahoots with Team Rocket? The only way to find out will be to use a little industrial espionage, so get your team built up strong and prepare to go on a stealth mission!'

Team Rocket occupation
Fans of the TV show are probably beginning to notice that the ruthless Team Rocket of the game doesn't have a whole heck of a lot in common with the bumbling idiots depicted on TV. Their mission of world dominance has led them to Saffron City, headquarters of the Silph Company. Team Rocket has basically occupied the entire city, sending respectable citizens running while they force the staff of Silph Co. to make advanced weaponry for their nefarious purposes.

Mr. Psychic
Saffron's a pretty dull place for a city of its size. Outside of the Poké Center and the Poké Mart, there are only two buildings you can enter at this time. One is the Fighting Dojo (the left of the two Gyms at the top of town), and the other is Mr. Psychic's House (bottom right corner of town). Enter and he will give you your heart's desire--as long as your heart's desires is TM 29, Psychic. And it might as well be, since Psychic does a lot fo damage, almost always hits, and has a 30% chance of temporarily lowering its target's "Special" statistic.

Mimic Girl
Once you've driven the Rockets away by reclaiming the Silph Company building, you can enter the house in the upper left corner of town. The little girl who lives here loves to mimic other people. She repeats everything you say, and you won't be able to have a normal conversation with her at all unless you bring her a Poké Doll. If you don't have one, head back to the Celadon Department Store to buy one. Give it to Copycat to recieve TM 31, Mimic, in return. This skill automatically repeats the last attack done to you by your opponent. Not always useful, but at least virtually any Pokémon can learn it. Maybe now she'll feel less shy and be able to relate to people normally!

The Fighting Dojo
You won't get a badge for taking down this optional Gym, but you will get something just as good: One of two Pokémon that can be found nowhere else in the game. Besides, beating this Gym is a cinch. The Pokémon used by the Blackbelts may be powerful, but all rely on the same Fighting and Normal style attacks. That means a single Ghost-type enemy can take down everything without being hit (Hitmonchan does have one seldom used Fire-type technique, but that's all you have to fear). When you've bested the Karate Master, he'll offer you your pick of his pets.

Trainer Battle 5: SABRINA
You can't get into Sabrina's Gym until you've saved the Silph Co. President within the Silph Company building. Only then will the Rocket blocking the door go away, and you can enter Sabrina's maze of teleport squares.

The least confrontational way is to take the first teleporter, then walk straight up to the next one, then straight across triggering one trainer fight, then straight down twice. You can avoid the trainer fight all together if you hug the bottom wall as you go from square to square.

Psychic Pokémon are too defensive to pose much of a threat, but some, especially the at the end of Sabrina's roster, can be a serious pain. Bug Pokémon are strong here, but it's better just to use your strongest Pokémon to dish out the damage before the enemy defenses can kick in.
