cheat
You have to beat the elite four and then go to cerulean cave and then you go all the way through then at the end is mew two and you have to catch it that is it
The best way to catch Mew is to catch the two Shedninjas on top of the mountain. Mew is vulnerable to Ghost-type PokeAssists. Use those and couple it with a Fighting-type PokeAssist for a good chance of capture.
before you catch mewtwo type in "one" then save then talk to it its A MEW wee
On heartgold, it is only available through a Nintendo event. But another way is to trade from another game, where you might have caught mew. Hope I helped!
Mew Three does not exist.
you get a master ball and catch it that way
the only way to catch mew is to defeat the elite four
You can't, there's only one time to catch it, and only one way; Master Ball.
there was actually a way to get mew. Pokemon summer day camps were place at toys r us stores across the UK Also you can actually catch a Mew in Pokemon Emerald by obtaining an 'Old Sea Map' and using the Ferry in Lilycove to sail to Final Island, where you can catch it in the tall grass. Then you can trade the Mew via Pal Park to your copy of Pearl, or Diamond. Another way is to use an Action Replay, but that's cheating...
mew-two dude hes awsom you can tell cuss the onlay way to catch him is with a masterball
there's no possible way to catch mew in the game. you have to go to an event in REAL LIFE to get it or from wi-fi if you've already seen it.
The only legit way to obtain Mew is through a Nintendo event. In FireRed and LeafGreen you will need an event-only item to travel to the last two islands where you can catch that pokémon.
