Note: Not to be confused with Bianca from Pokémon Black, White, Black 2 and White 2, whose Japanese name is Bel.
Bianca (Japanese: カノン Kanon) is a primary character in Pokémon Heroes: Latios & Latias. She is the granddaughter of Lorenzo and the best friend of Latias, who has a tendency to shapeshift into her. Bianca has a hairstyle similar to Latias' wings, and can usually be identified from Latias' illusion by the white beret she wears. It appears she wishes to be a painter or possibly a Pokémon watcher similar to Tracey. She lives in Alto Mare in the Johto region.
Bianca first appeared in the museum, drawing some of the stain glass windows in the museum. Ash was distracted by her, since he previously saved Latias in the form of Bianca and believed she was the same girl he rescued. Wanting to know why she disappeared after he saved "her", Ash and Pikachu pursued her across Alto Mare, finally catching up to her on the other side of the bridge, but Bianca was confused by his questions and quickly departed. Ash lost track of Bianca but instead followed Latias to the secret garden. As Latios attacked Ash, Bianca appeared and believed Ash was the one attacking. Lorenzo soon appeared and stopped the fighting, Bianca believing that Ash was trying to harm Latios. She soon learned the truth and apologized for her actions, becoming friends with Ash. She was later captured along with Lorenzo in the museum and held hostage, and told Latios to use Sight Sharing to bring Ash and Latias to the museum. Bianca and Lorenzo were freed and helped save Latios from being tortured. Bianca was deeply upset by Latios's sacrificial death and received the new Soul Dew.
The conclusion of the film briefly sees her finishing a drawing. The drawing, which is of Ash and Pikachu, was given to Ash by either Bianca, who had left her hat on her easel, or Latias in the form of Bianca: which is the case is the subject of debate. When Ash received the sketch, the girl kissed him. Bianca was seen again in the credits drawing another sketch by the harbor.
- It is shown that Bianca and Latias are good friends, as when Latias transforms into a human, her appearance in her human disguise is identical to Bianca's appearance.
