you will find one in
team aqua's hideoutThe professor
you can't
in team aquas hide out
from your enemy teams base
I am pretty sure you get a masterball.
In team aqua's hideout
You must either get a masterball from team aqua base or game corner. Then you must fight a legendary and throw the masterball right away.
give a Pokemon the masterball and put it in the daycare with a ditto then it will be cloned!!!!!!
u run into her in random places u well want to keep the masterball
There is only one masterball in sapphire and to get it you need to be through a lot of the game. The only place to get it is in team Aquas Hideout. Oh, there is one other place which is Lilycove Department store, where you can draw a lottery. Match all 5 numbers and you win a masterball.
fire red: after you give the sapphire to celio, now you can trade with Pokemon ruby, sapphire and emerald
If you chose charmander as your starter beat the game and get the national dex plus deliver the ruby and sapphire to celio then go to route 1 once you find it use the masterball on it to get it.
