Bianca is shown to be very excitable, for instance when a Minccino stole the Badge case and Ash attempted to use Oshawott to get it back, Bianca commanded him to use Hydro Pump despite the fact that Oshawott wasn't her Pokémon nor did he even know that move. She later made the same mistake when she commanded Pikachu to use Zap Cannon. She also had a battle against Ash, where she used her Pignite against his Pikachu. Ash was planning to use Oshawott for said battle but Bianca demanded that he use Pikachu. She lost the battle after putting up a hard fight.
