you can't!
You cannot rebattle Gym Leaders.
you cant
Unfortunatly you cant, this feature in heartgold/ soulsilver was epic!
You can't. You could use the VS Seeker to challenge Trainers outside of battles though. It was a stupid choice by Nintendo not to let us fight gym battles again. XP
You defeat the gym leaders in Pearl. ~KKMG1
Defeat all of the gym leaders in Pearl. ~KKMG1
we can get 8 gym badges byfighting all the gym leaders in Pokemon pearl.
There isn't a second encounter with gym leaders
It is not possible to reverse the order of Gym Leaders in Pokemon Pearl. This is due to how the story of the game is written. And the fact that the 8th Gym Leader will be impossible to beat at the start of the game.
Yes, but they have to want the rematch. your pokenav has a feature called match call that lets you know when a trainer wants a rematch. There will be a box with a pokeball design on it next to the name of the trainer (or gym leader).
Gym Leaders: Roark, Gardenia, Maylene, Wake, Fantina, Byron, Candace, and Volkner.
You Would Need To Specify Which Of The 8 Gym Leaders You Want To Get To.
