Challenging Gym Leaders
Gym leaders are a bit particular about who they let challenge them. This is sort of a requirement when you run an establishment that every trainer across the continent aspires to visit at least once in their pokemon careers. Criteria for allowing a challenge will vary widely from trainer to trainer, but it will usually, for the purpose of making this a proper role-playing game, involve some sort of plot device like performing a specific task for the leader or somehow proving your worth through your interactions with him/her. This may not always be the case (some gyms might simply require a small donation in order to challenge them). However, these rare instances are the exception, rather than the rule. Once you have met the criteria for challenging a gym, you will be able to challenge it at any time, any number of times you want. There may be a recurring fee, but you usually won’t have to meet the challenge criteria over and over again. Once you’ve proven yourself to the gym leader, they will let you challenge them any time.
