This is true, but they didn't have a lot of personality and their back-story was boring. This is in contrast to Wally who had a definite personality and a more interesting story. So yeah, they acted out the part of a rival at times, but as characters, they themselves weren't especially deep. Basically they are 'generic. Bianca is really the first female rival with an actual story and personality, is what I'm saying, and I want another female rival that also has a unique story and personality, but one that's more aggressive than Bianca.
