It depends on your starter pokemon. I don't actually know their names. If you choose Oshawott(water), you will face grass type pokemon. If you choose Tepig(fire), you will face water type pokemon. If you choose Snivy(grass) you will face fire type pokemon. If you want to beat them, go to the right corner of the town and go into the dream yard. Go to the girl at the end and she will give you a pansage(grass) if you have Tepig, panpour(water) if you have Snivy and pansear(fire) if you have Oshawott.
The gym leader will first send out a plain normal type followed by your pokemon's weakness.

You cannot rebattle Gym Leader in Pokemon White.
go to the first bridge and vala
if u need this answer u must be stupid!
no. its siren, the first gym leader.
You kill the Gym Leader's Pokemon with your Tepig.
He's a Gym Leader.
The first Gym Leader who is Falkner, the Violet City Gym Leader, he has a Pidgey and a Pidgeotto.
You first must make sure that the gym leader is in the gym, because in some games you have to locate the gym leaders first. After that, you may have to get through a puzzle in the pokemon gym to get to the gym leader at the end of the puzzle. After that, you will battle the gym leader, and if all of her Pokemon faint, then you will probably be given a gym badge.
