O is curious, but not smart. Unlike other Alphablocks, he is incapable of speaking normally: O can only make the sounds that he spells. (This normally means either his short sound [ɒ] or his long sound [əʊ]; the latter doubles as O's name, as heard in ABC.

Sometimes, she is so overprotective of Mayu that she would easily drive herself to the brink of humiliating Mayu publ

Miyako is as ditzy as the original Bubbles. She does not seem to understand her powers completely, along with a few other things. She is, however, the most mature Powerpuff Girl Z on the team and will try to calm any situation, although she too can be angered when provoked. She is also very polite and always uses honorifics at the end of names. She is concerned with shopping, her appearance, and her outfits, and perhaps because of this, she seems to be very popular among her male classmates.
