Hidden Pokémon
Pikachu:
This Pokemon isn't actually hidden but he is hard to find.
He is rare in the Viridian Forest but if you search a while,
you'll eventually see one. Pikachu is also more common in
the power plant.
Farfetch'd:
In Vermilion City, there is a guy who will trade a Spearow for
his Farfetch'd. This is the only way to catch him.
Mr. Mime:
At the exit of Diglett's Cave (on route 2) there is a
person who will trade an Abra for his Mr. Mime.
Eevee:
In Celadon City, go through the back of the Celadon Mansion and
go up to the top floor. On the table will be an Eevee.
Jolteon, Flareon, and Vaporeon:
Use either the fire, electric, or water stone on Eevee. You
only get one Eevee, so you must trade to get the other two.
Hitmonlee and Hitmonchan:
Defeat all the trainers in the Fighting Dojo and the leader will
award you with your choice of Hitmonchan or Hitmonlee. You also
have to trade to get the one you don't choose.
Zapdos:
Along with all ofthe rarest Pokemon, Zapdos is hard to
catch. The best way to catch him is to wear him down to very
little energy and paralyze him or put him to sleep. Only use
Ultra Balls on him. Pokeballs are no good.
Articuno:
This Pokemon lives in the Seafoam Islands and isn't easy to
catch. Use the same techniques as on Zapdos.
Moltres:
Moltres lurks on Victory Road. He is another tough Pokemon to
catch. Use the same strategies as you ued with the other
legendary birds.
Mewtwo:
After you defeat Gary for the last time, this area opens up just
to the northwest of Cerulean City. Go through the Unknown
Dungon and fight Mewtwo. If you still have the only Master
Ball you can get, go ahead and use it to capture the Mewtwo,
otherwise, put it to sleep immediately, and then weaken it until
it can be caught with Ultra Balls. It could take around 50
Ultra Balls to catch him.
Mew:
On the S.S. Anne, get cut from the captian and then get in a
battle and black out. The S.S. Anne will not leave and once you
get surf and strenth come back and surf to a truck by the S.S.
Anne. Use strenth on the truck and a item ball will appear. In
the ball is Mew! Or you can use the Gameshark code, 011564D1, and
catch him anywhere.
