Clay (Japanese: ヤーコン Yaakon) is the Gym Leader of the Driftveil City Gym. His gym is the fifth gym to be challenged by the trainer. He specializes in using Ground-typePokémon. He will award the player the Quake Badge if defeated. His outfit resembles that of a Texan businessman's and he has a Texan accent.
Clay first appears after Elesa asks him lower the bridge that links Nimbasa and Driftveil. He later blames the player and Cheren for allowing Team Plasma into Driftveil. Since he blames them, he asks the player to find the Plasma members. They can be found in the Cold Storage. After finding Team Plasma, Clay comes in and arrests Team Plasma but they escape. After that, the player can challenge Clay.
He is later seen helping the player in N's Castle by holding off all of the Sages alongside the other Gym Leaders, excluding Cilan, Chili and Cress.
Clay debuted in The Mighty Accelguard to the Rescue!, though it was a short cameo. When Ash arrived to challenge him, he respectfully declined because he said he had to check on a mine he owned and left the Gym.
He appeared again in the first part of Stopping the Rage of Legends! where Ash challenged him to a Gym Battle but declined yet again saying he needed Revival herbs.
Clay's Palpitoad is the second of Clay's three Pokémon that appeared during Ash's Gym battle. It appeared to battle Ash's Snivy in BW063.
Palpitoad's moves are Hydro Pump, Mud Bomb,and Rock Smash.
Clay's Japanese Leader title is アンダーグラウンド ボス / Andaaguraundo Bosu. "Underground Boss"
