I suggest having a Gyarados with these attacks: Thunder, Hydro Pump, Blizzard and Fire Blast. A Camerupt with Eruption, Fire Blast and Earthquake.(lvl 50. only:D)
Nothing
After you beat the Pokemon league, you can train all your Pokemon, challenge the battle tower, do both, or start over.( i don't recommend starting over)
We can get other regions starter Pokemon if we defeat the battle tower
after you beat battle tower just do Pokemon contests or catch legendaries other than that nothing else to do so buy ruby or emerald then trade and just keep doing that then get gamecube at gamestop for 30 dollars and get the Pokemon on gamecube and just do that .hope i helped
Well try to beat the battle tower cause its not like emerald its like ruby and Sapphire but when platinum comes its like emerald so beat the battle tower and ur done with the whole game.
if you mean on the trainer card you need to beat the league complete the pokedex hatch an egg and complete battle tower
beat 50 trainers in a row in the battle tower
At the fight area (after you beat the Pokemon league)
To get fans, battle your friends, and if you beat your friend in a battle. you should get fans
Nothing.
Yes.
you cannot ever beat the battle tower. but if you have completed the sinnoh pokedex then the battle tower will help you complete it. you can battle at the battle tower as long as you want.
