Double Battle and single would be Groudon and Thyplosion first and Kyogreo and Wailord second, single is any Pokemon with Recover I recomend a team of Deoxes.
Well, There isn't ANY Powerful Pokemon. There isn't a Single Pokemon that can clear the Entire Battle Tower. You Need a Team. Give each Pokemon Different Moves, None of the Same Type. But yea. That's Really All there is to it.
No never! For Emerald the ending is the best becase there is so much to do at Battle Frontier. And on Pearl, Diamond, Platinum there is the battle tower and not to forget the incredible Wi-Fi Pokemon will last forever man! Where is your spirit?
you open the door and enter :P it is this simple :P
I would say Spore is the best, because it has 100% accuracy and is a sleep-inducing move, which virtually takes out a Pokemon for the rest of the battle.
u cant use to Pokemon games on 1 battle revolution save its 1 or the other its best to see wich 1 has the best Pokemon because u will win more
go to the resort area and find a syther to battle and it will level your Pokemon about 615 points ________________________________________________________________________________________________ What about before the Pokemon league?
Diamond is not a Pokemon but i think Arceus is one of the strongest Pokemon ever.
electivire is very good so is heatran charizard staraptor im naming off the ones that can be in the battle tower.
the best Pokemon on diamond would be arceus but you can only get that from action replay, other than that i think the best Pokemon would be giritina..
the best Pokemon for the Pokemon league is definetly latios
Palkia
the best Pokemon in diamond is arceus, but you have to use action replay or wi-fi mystery gift
