You can catch MEWTWO ,not Mewto, at the end of Cerulean cave
no
you can't catch him on sapphire but you can on emerald.
I think that's all you can do in the game
yes
with a master ball
That's impossible.
Yes,its level is 70.
Unfortuenetly u cant catch mewto on emerald only on fire red.green and dimond and pearl! SORRY SUCKERS!!!!!!!
you can still go to cerulean cave to catch it like in firered and leafgreen
you cant do anything because you did everything
im pretty sure after that you'll have to complete the national pokedex
