yes
You need to have a national dex and need to have caught 70 or 110 pokemon.(I don't remember the exact number and whether you have to see or catch these number of pokemons but I am sure you have to do all these to get past the cave.You will get a Mewtwo in there).
To Catch Mewtwo You Need A Action Replay.
he is in cerulean cave at the very bottom, you need to beat the league to acess the cave though
You cant on Firered - sorry
you will see mewtwo if you follow the maze you will need strength rock smash flash and surf
You only need to see them but you have to catch at least 60 Pokemon to get the national dex
its bulbasaur, and you need to migrate it from fire red or leaf green.
ok if you want to know how to get mewtwo firstly all you need is Pokemon firered/leafgreen and capture mewtwo on that secondly you need the national dex thirdly need to beat the elete four (can't spell it) and fourthly some COMMON SENSE because all you do is migrate it you can migrate 6 Pokemon a day and you find 'em in the pal park or use action replay hope this helps ok if you want to know how to get mewtwo firstly all you need is Pokemon firered/leafgreen and capture mewtwo on that secondly you need the national dex thirdly need to beat the elete four (can't spell it) and fourthly some COMMON SENSE because all you do is migrate it you can migrate 6 Pokemon a day and you find 'em in the pal park or use action replay hope this helps
