Hikaru

Bailey is a character of the day who appeared in Flower Power. She travels around in her van, where she trains Pokémon to dance and perform various acrobatic moves to put on shows, similar to a Pokémon Coordinator.

Ash and his friends met Bailey at the Florando Pokémon Exhibition. She later helped teach Pikachu several dance-like dodging techniques to assist in his upcoming battles. One of her Bellossom lacked the confidence to do a complex flip move until a fight with Team Rocket inspired it to finally execute it perfectly.
