You can't be a gym leader on any Pokemon game. There may be some cheat which means you can stand in the place of a gym leader, but that's it.
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.
he cant come
Make sure you battle everyone else in the gym and you will get it.
beat all gyms or cheat with ar ds
you have to break the code
This is also what im finding but im not sure. I have the code for trainer rebattle but not gym leader rebattle. Well im sure i have seen "Press R to Rebattle Gym Leader"
To make fantina (hearthormes gym Leader) appear you have to get the hm surf before you challenge the gym leader. To get the hm you have to go to celistec town and talk to a old lady and she says to battle a galactic guy and you have to go in the ruin and she will go in to and she will give you the hm and the gym leader will appear.
Gym Leader Flannery is the leader of the Lavaridge Gym. The Gym is a Fire-type Gym.
The gym leader.
You can't. Unless you use a cheat code to catch them pokemon.
