train your Pokemon or battle and trade with freinds.
Mew two sould be at the end of the cave in cerulean city after you beat the elite 4.
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
i think you beat the eleat 4 a lot of times and go where you found mew two....
Beat the adventure with jiggy puff, pickachu, and pichu
i dont know beat the game i gues
cerulean cave after you beat all the gym leaders
well to me if mewtwo can beat entie and mew can almost beat mewtwo that means mew would probaly destoy entie
easy after you beat mew there will be more areas to unlock hope it helps
You face your rival who is the champion, and blow his brains out, i mean hopefully win and go for the legendary mew two and mew.
Mew does not evolve you have to get mew two separately
arceus
you catch mewtwo in the cerulean city cave after you beat the Pokemon league
