After you beat Professor Ein for the second time in Realgam Tower Eagun will send you an e-mail but it cuts off before he is finished. Go visit him and he will give you the master ball.
I suggest using it on Tyranitar when you battle Evice, because he is the strongest shadow Pokemon in the game.
every game you do
No.
there is only one masterball
1 Masterball, unless you recieve a traded pokemon which is holding a Masterball
You get a masterball after you beat Cyrus in the galactic HQ
The Colosseums are... The Gateway Colosseum, the Main Street Colosseum, the Waterfall Colosseum, the Neon Colosseum, the Crystal Colosseum, the Sunny Park Colosseum, the Magma Colosseum, the Sunset Colosseum, the Courtyard Colosseum, and the Stargazer Colosseum.
how do you get the 999 masterball cheat for Pokemon platinum actionreplay
The final Colosseum is the Deep Colosseum after the Game, Pokemon here are Level 60-65, this is where you can catch the Pokemon you missed from the Admins earlier and a Shadow Shuckle.
if you can connect colosseum to a gba, then trade the Pokemon to the gba game and migrate!
for Pokemon there are no codes
The only way to get more masterballs without cheating is to have other leafgreen versions or firered or ruby or sapphire or emerald or Pokemon colosseum or Pokemon xd gale of darkness trade the masterball that those games get to leafgreen other than that you have to win the lottery in ruby and sapphire and emerald at lilycove city to get another masterball then trade it to leafgreen.
if u use any masterball cheat u get bad egg in Pokemon PC
