start a new game. in cerucean city there is a slowpoke trainer.when you first get there save then find out where he is. after you find him turn off the game then turn it back on.get a abraand go to the poiekmon center and go to a trainer one step before he will see you and use teleport he will se you then you will go. your start button will not work for a moment. go fight the slowpoke trainer(without battling others). then use teleport after the baTTLE. go to the bridge and the start menu will pop up. close it and a level 7 mew will pop up and you will have to catch it yourself. good luck!!!
Mew cannot be caught in Pokemon diamond as well as mewtwo and the rest of the legendarysfrom previous games. they must be transferred via pal park
MEW is only in one game WITHOUT AN EVENT. If you want mew buy Pokemon blue or get GameShark to warp to the event island where it is located in emerald.
You can only get mew through a Nintendo event and not actually in regular ruby gameplay
you have to trade from emerald for one
You can't get mew in firered or leafgreen.
mew and mew two
mew and mew two
There is no Mew 3.
Mewtwo? Plus you cannot get Mew in Leafgreen or Firered.
You can't catch mew on leafgreen you need gameshark codes for that
Mew two
No.
Mew has to be traded from emerald and ho-oh you have to get from Pokemon colosseum.
Mewtwo, yes, if you have a FireRed or LeafGreen with Mewtwo.
Cheatcodes or luck.
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.
