How Do You Get Mew In Pokemon Leaf Green?

In order to catch Mewtwo, first one must defeat the elite four and then get the sapphire and the ruby and then hand it to Celio. Then go to the island with the brail cave. Using the brail booklet, enter the entrance door reading 'use cut'. Follow the direction that is given.to get the sapphire, you must beat everyone in the Rocket Warehouse. Fly to Cerulean city and go inside the Cerulean Cave. Go through the maze and find Mewtwo. He is very tough to catch, but it's worth the effort. Of course, it won't be hard to catch him with the Master Ball if you have managed to save it. If not keep attempting and you might ultimately catch him. He knows Psychic, Recover, Barrier and Swift.

In order to catch mew, you will have to first beat the elite four 12 times. You have to go in the cave near Indigo plateau called Victory road. Just walk around for a while and he will eventually appear. I travelled for about 30 minutes because he is so rare.

Breed mewtwo w/ meowth and when the egg hatch you will be surprice b'cpz its mew^_^

Get the two stones called ruby and sapphire.
Go to the cerulean then to the cave   
pass the maze and you will find mewtwo!

U go to cerulean city and u beat misty afterwards u go to nugget bridge lose to the person who gives u the nugget 2 times then the 3rd time beat him battle every single trainer on your way to bill if u do it properly when u walk in bills house when u talk to him u will have a pokemon battle against a level 7-20 mew

Just beat the elite4 1,000,000 times and mew will appear wild on the cerulean cave with Selebi and Karachi.

Wow guys you are so cool

To catch mew u need to do this beat the elite 4 12 times go to victory road pass the whole thing with out fainting and go back 2 times and then u u must catch an onix lvl 52 and round in araound 4 times and u find mew

Lol i told my friends that have pokemon yellow version he say that he use cheat in pokemon yellow to get mew he say that compatible in leafgreen that he use cheat in pokemon yellow but i dont yet the cheat i ask him and i tell to you the cheat ^_^ XD

Beat elite 4 12 times then go to cerulean cave and go to the spot where mewtwo is caught. (Mewtwo MUST BE CAUGHT OR DEFEATED) run back and forth a few times and mew should appear. Mew is VERY hard to catch but its really worth it knowing that mew can learn every attack!

U need to have 2 leefgreen or 2 firered and beat 1 game and trade a pokemon that knows cut and dont go on the boat keep going until u have surf and go to the boat but dont get on look to ur rite and use surf keep going until u see a truck and u need strength use it on the bolders then on the truck and mew will be there!!!!!!!!!!!!!!!!!!!                                                                  LV.1-100

Go out of the underground tunnel(lavender) and when you are about to battle the person pause the game and fly to cerulean battle the first youngster he must walk up to you then fly back to lavender and walk out of the town to the underground place  out of the town you'll find mew lv7

Beat E4 12x go to curlean cave get mew go to VR celebi will appear

I dont know but i heard that after u get mew bet the elite4 12 times and Selebi will appear in the wild i n cerulean  cave.

To catch mewtwo first defeat the elite four then
get the 2 rocks called rubt and saphire and
bring them to Celio and after go to Cerulean
City and go to rute 24 and theres water
in the white side surf until you get to a cave
and follow a path til you get to mewtwo

This doesn't go for Fire Red or Leaf Green, but it works on Yellow and I'm assuming Red and Blue, and you can do it with one badge! After you go through Mt. Moon and into Cerulean City, defeat Gary and all the people on Golden Bridge. There's a guy in the grass to the right, DON'T defeat him yet, instead, continue to the right and battle whomever you wish EXCLUDING the guy with the level 17 Slowpoke. Talk to Bill and go to Route 5, there you need to catch a Abra because it knows Teleport (it's easier to catch it if someone in your party puts it to sleep like a higher leveled Butterfree). Once that's all said and done, act like you're walking back to Bill and this time, turn left to the guy in the grass. Right before the battle you might want to save in case you mess up, walk up to him and pause before he sees you, then use Teleport (the first time walk up to him, the square you get stopped on when he sees you is the square you teleport on). It will take you to Cerulean City, notice that your pause screen doesn't work now.. Finally, go to the kid with the Slowpoke and battle him, after the battle, teleport again. You're just about to get Mew now! The last step is to walk not even half way up the Golden Bridge and a random battle will occur, it's a level 7 Mew. It wasn't SUPER hard to catch, but it was annoying, using sleep helps so I would recommend getting one in the beginning of the game (Veridian Forest). Hope that helps!
