you can't
theres no such thing as mewthree
you can only get mewthree in leafgreen firered, but you could migrate... mewthree is a fake Pokemon is it worth the chance of ruining you game ?
MewThree X is a Hacked Pokemon name. MewThree X is just a name that Hackers created. MewThree X isn't a real Pokemon.
you have to hack it.or buy a hacked game called Pokemon chaos black.it already has mewthree X and mewthree.also mew and mewtwo.
Mewtree is just a fan-made Pokémon and it does not exist in any games.
Mewthree is a Pokemon in only Pokemon Chaos Black,which is only a hacked game of FireRed and LeafGreen.But other than that it doesn't exist.
mewthree doesn't exist yet, or will never. There are several fake videos on youtube, and several fake images on other websites, but NONE are confirmed. if you ment mew or mewtwo, then you have to transfer both Pokemon from FireRed or LeafGreen.
You can't.
Mewthree is fake, REPEAT MEWTHREE IS FAKE >_<
There is no Mewthree period
