Marble met Ash and his friends in front of an old mansion. Suddenly, her Luxray attacked Ash's Pikachu. After the battle was over, she called the security guards because she thought they were the group of thieves, The Bandit Beauties Three (Japanese: The Three Beauties), that were trying to steal the Old Charm.

She explains that she—the best Officer Jenny student—was called by Matthew to protect the Old Charm from being stolen. Then, she tells that the Luxray she raised since it was a Luxio has a problem in learning Charge Beam. Toward the end of the episode, her Luxray finally learns Charge Beam; with Pikachu, it attacks Team Rocket and makes them blast off.
