Do you mean a gym leader?
In Pokemon Diamond, you are not allowed to go to Leader Fantina's Gym. (Shadow Type Pokemon). So, get to Veilstone City and Battle Leader Maylene. She uses fighting type pokemon. It is the same with pearl. In Pokemon Platinum, when you just get in, a Buneary will bump in to you and a trainer will come. She thanks you and tells you to go to the contest hall. After your mom gives you a tuxedo/dress, there is a girl in a purple dress which is Leader Fantina. She goes back to the gym, and you are available to battle her.
