No you can not
Mewtwo? Plus you cannot get Mew in Leafgreen or Firered.
No you cant get Mew on leaf green, but you can get Mewtwo in Cerulean Cave.
Mewtwo, yes, if you have a FireRed or LeafGreen with Mewtwo.
no but mewtwo is
you don't. You can't find either Mew or Mewtwo in Emerald; you have to trade from FireRed or LeafGreen to get Mewtwo. You can't get Mew without an event or cheating.
you can not get mew without the mew glitch but if you go to the end of cerulean cave you can get mewtwo
Use Action Replay
no you can only see mewtwo in cerulean city
Mewtwo ,Mew, Zapdos, Articuno, Moltres, & come more
no because there isn't a mew-three just mew and mew-two sorry
Mew was distributed at an event once, but that is long over and sadly if you want a mew in leafgreen now, you'll need help from other games or you could use cheat codes.
Sorry you can't catch mew, once you advance in the game you can catch a legendary/special mewtwo (evolved mew).
