Elizaveta Boyarskaya (Russian) and Ruby Rose (English dub) as Bianca.
Bianca went through the most re-drawings, sketches and 3D models out of all the film's characters. The designers intended to achieve a "pretty" and "decisive" style for her. The character was originally planned to have light skin, but the final result for her was a wolf with darker blue fur given the light color "looked bad" with Grey. As Boyarskaya explained, considering that Bianca was "so beautiful," she had to speak her lines at a much higher pitch than she was comfortable with, which caused her to "almost [break her] voice."
