After defeating Team Rocket at the Radio Tower, go to Blackthorn City and enter the gym. This gym has boulders that can be pushed from the 2F and down into the pools of lava. Once the boulders are all down, you can cross to battle the gym leader. Clair uses Dragon type Pokémon. Dragonair will use Thunder Wave to paralyze opponents.
