There is no Mew in FireRed or LeafGreen.
You can't..........................Mew does exist in the pokedex but it isn't there in the game......hope this helps
no.
There no Mew in firered.
You catch it in the Master ball that you got earlier in the game.
You can't unless you hack the game, I'm afraid.
There are no more special events, so you have to already have a mew in a different game and trade it to your fire red.
You must capture Mew on Emerald and trade it to FireRed.
Some people say to nickname your starter Pokemon "Mew" and it will play as mew for the rest of the game but I never tested it...
You can't get mew in firered or leafgreen.
Its not possible to get mew in firered only emerald can via Nintendo event.
Mewthree is not a real Pokemon its a fake one created by a guy who made a game out of a firered .There are only mew and mew-two .
