Katsura

Katsura is the highly intelligent Gym Leader of the Guren Gym, specializing in Fire-type Pokémon and awarding the Volcano Badge to challengers who defeat him. He loves riddles and puns, even at awkward moments, but is a serious opponent who expects trainers to earn their victory. His tactics make deliberate use of the Gym's volcanic setting to offset Fire Pokémon's vulnerability to Water types.
