Hmm, good point. Then perhaps you could contrast the two sides - cold and calculating, or at least calm (Haschwalth, Pernida [presumably], Liltotto, Cang, Quilge [debatable], BG9, Robert, Meninas, Gremmy[ish], Nianzol, and Lille) vs. hot-blooded and emotional, or at least expressive (Askin, Bambietta, Äs, Bazz-B, PePe, Jerome, MASK, Candice, NaNaNa, and Giselle). The two groups are far more evenly split than they were with the Arrancar, where only a few members remained stoic throughout their appearance (Starrk, Harribel, and Ulquiorra).
