once you defeat the elite four. and have hm rock smash and strength
Mewtwo is in the Cerulean Cave near Cerulean City. To get to Cerulean cave though, you have to get surf, and complete two achievements such as hatch an egg and delete the Elite Four.
after you beat red it will be open and u can get mew2 good luck you will need it (and escape ropes)
go to cerulean cave after you beat the elite four and help celio fix his machine on those islands. you go into cerulean cave work your way through that and mewtwo is in there
MewTwo can be found and caught in Cerulean Cave. Hint save before you battle him and if you fail you can try again.
Its in the northern part of Cerulean City. But you can only get there from route 24 by using surf. Also, in order to enter, you have to have all 16 gym badges and solve a maze to get to Mew2
Mew 3 doesn't exist and the only Mew-anything you can find is mew2 at the back of Cerulean Cave.
you have to play Pokemon leaf green or fire red until you beat the eliete four, then you go to cerulean and go into the cave on the left, at the end of the cave is mew2 then you trade the Pokemon over to diamond via the pal park which you unlock after beating diamond's league
u cant. its event exclusive-sorry. but go to cerclean cave, and eventually u will find a mewtwo. just as good right? not as cute as mew, though... :(mew2 is some where in cerulean cave

uh...... if you didn't go into the dark cave in johto and the cave east to cerulean and north of the electric plant. P.S don't mistake the cave in cerulean city. not the cerulean cave!!!!!!!!!!!!!
