BUT, that's only the FIRST 8 Gyms, after you battled (and won) all of them, you will have the ability to trvel to the land of Kanto where you battle other Gyms.
Hope this helps XD
8 gyms in Johto 8 gyms in Kanto 8+8=16 16 gyms
you beat all 8 kanto gyms then go to prof oak
Professor Elm gives it to you after you defeat the first 8 gyms. In other words, all the gyms of Johto.
There is 16, 8 in Johto, 8 in Kanto.
Talk to Prof. Oak in Pallet Town.
Theres 8 , as usual.
Defeat THE 8 gyms at johto than coms à shady character to give you à key to open it
Aside from the one you get from Elm after you beat the first 8 gyms, the only other way to get one (aside from AR) is to win the Radio Tower Lottery by matching ALL the numbers.
If you are reffering to Pokemong Heart Gold and Soul Silver, You get them in the begining of the game.. After the first 8 Gyms you get one from another set. After you defeat red you get one from the other last set.
I'm not sure i understand the question Beat all 8 gyms and pick up the Master Ball from Elm. Someone will tell you to go battle the Kimono Girls in Ecruteak City. Beat them, and climb the tower.
In Kanto.
After you beat 8 gyms proffeser elm gives you it dummy
