Heading to Violet City for the first gym, Ash and company meet Casey, a new trainer and baseball fan who eagerly challenges Ash to a battle. When Ash easily beats all three of her Pokémon with just his Charizard, she gets upset and makes an alliance with Team Rocket to get back at Ash, until she finds out that Team Rocket was just using her.
