How To Get The National Pokedex And Mewtwo:

Hi it's Mattyscizor!!!

To get the National Pokedex:

Before you beat the Pokemon league make sure you have 60 or more Pokemon.

Then after the credits are finished Professor Oak will call you to his lab and give you and your Rival the National Pokedex!

Then go to One Island and talk to Celio hewill say the machine needs a special jewel that will operate the trade machine (so you can trade with Pokemon Ruby/Sapphire.

Then go to the bit where you get Moltres and there are two Rocket grunts talking to each other, aproach them and you will see they have dug a hole into a cave battle one then battle the other, they will flee.

Now work your way through the cave and you will find a Ruby.

Exit the cave and go back to Celio, he will give you a Rainbow ticket!

Now go to island 6 and throgh Ruin valley (there are some Gold/ silver pokemon here so don't forget to catch some!) until you reach a metal door talk to it and it says 'CUT' in Braile, so use cut and go inside.

Go through the hole.

Go through north hole, then the west hole, then the east hole and then the south hole and you will find a Sapphire but a geeky Rocket scientist steals it!!

Now go to five island go through the meadow and find the Rocket warehouse you will enter the passwords and go in.

work your way through the maze and find the scientist that stole the Sapphire, beat him and he will give it back.

Go back to Celio and give him the Sapphire, you can now trade with Pokemon Ruby, Sapphire and Colesseum.

Now go to Four island again and go to east side and into the icefall cave (need surf). now go through the door and find another hole in the wall, go through it.

Skid along the ice until you find TM07: Waterfall, teach it to a pokemon and go back out through the hole, now go to waterfall on the oppisite side of the cave and up the waterfall.

you will see the first elite four arguing with to grunts you fight one, she fights one.

Now go out of the cave and into the house with loads of dolls, talk to the first elite four and she will return to the Pokemon League.

But don't challege it yet for you might just be thrashed...

stock up on Ultra balls and head to Curulean cave work your way through the maze (bring Max ethers or you'll never get through and find Mewtwo save the game and try your best to catch him...

Now you should be ready for the National League, I suggest to teach Mewtwo Brick Break, Earthquake, Thunder and Psychic.

But beware the league is SUPERSTRONG!

Good luck!
