Bianca is a cheerful girl, usually seen wearing a white skirt and sporting a green hat. Despite being indecisive at times, she has a strong side which manifests when she goes on a Pokémon journey without her father's consent. At first, she worries about being weak and wonders what to do in her life. Later on, she grows in confidence and accepts that she'll never be the strongest Trainer. She is shown to be very protective, volunteering as a bodyguard for various characters, including Professor Juniper at Chargestone Cave.
