She was a great character at the begining, when she had all those fun quirks and frequent outbursts of emotion (during the contests and otherwise). Then she grew progessively dull as her character 'matured', with her only saving grace being the interaction she got with Harley and Shuu, and those good ol' Grande Festibals.
She should have interacted with the other characters in the group more, and again, as the series went on, things sort of derailed to a point where you had to wonder why the hell she was travelling with Ash anyway. The most she seemed to get was the occassional scene with Masato, and even those were pretty hard to come by.
But she had...sorry, has a Combusken, which as everyone knows, is the BEST pokémon EVER. I mean, you don't diss a gal with a Combusken. Because Combusken is the best pokémon ever. The BEST ever, to be precise. Man oh man, was that Combusken the best. Ever.
Best ever.
The Combusken, that is.
