Seven.
Probably until you meet your Rival on it
If in Platinum, the win streak needs to be twenty one. One the 21st battle, Palmer challenges you.
2 1) Zombie Boy 2) Lady Gaga
there are 7 people in a room when you beat them all you get (bp) battle ponts
you face six people then the seventh battle is the leader
7 i think
i think is 75 or 100 hope i help
Ok...its really hard to beat the pokemons of Pokemon tower...When i beat 10 trainers of the battle tower(single),i got an item called Upgrade...
you can go back to Twinleaf and go to your rival's house, i dont know maybe what i did was what happens when i use too many cheats. i used lots of cheats to do get a 100 win streak in the battle tower
It doesn't matter about the wins. Just get an awesome streak. The leader of the battle tower only battled me when I used crappy Pokemon like Manectric, Dustox, and Dusclops. Although dusclops was pretty good. I still beat him anyway.
theres many things to do, provided you want to do them. 1) beat battle tower and get 100 kills in a row 2) find all the legendaries 3)complete your pokedex 4) try and get as many level 100's as possible
ok this seams crazy but u must beat the battle tower a bunch of times.(im not sure how many, but i know it from somewhere.)
