no it doesnt all that happens is that you go back to pallet town and then you can get mewtwo in the cave
maby you have a old version of Pokémon LeafGreen and when it came out , the Cerulean Cave wasn't finished.
you have to get a national dex by searching for all the pokemon.
After you beat lance, your enemy Gary will be at the end of the Elite 4 and when you win the battle against him you can go to the cave in Cerlaun city and get past the guy that is blocking it.
if you are playing firered/leafgreen you get to the elite 4 and beat them then you go to cerulean cave and catch mewtwo get it in your party then go to where you found mewtwo a bomb will go off and you have mew. sadly in heartgold/soulsilver you cant get except by migrating
you cant

you can do about anything after you just cant beat the gym leaders again.
Yes, you cant go pass Nimbasa or Opelucid city until you beat the elite four, N, and ghestis.
You can face Mewtwo if you go through Cerulean Cave. Just go north of Cerulean City, surf down the waterway, and enter the cave. If you can't make your way through, there are plenty of maps online that can help you. I recommend using the master ball on Mewtwo.
You can but the chances of that happening are 17%.
beat the elite four and the champion
im sorry but you cant???????????
