Kaoru Matsubara (松原かおる Matsubara Kaoru)/Powered Buttercup (パワード・バターカップ Pawādo Batākappu) is Buttercup's counterpart. She is much like her American counterpart in personality. She likes to skateboard and hates wearing skirts (and she even got a cold from wearing her PPGZ uniform.) She was the last to be hit by the white light. She loves sports and is very athletic at school. She initially dislikes her teammates because they are very "girly" and only joins due to the power she has achieved. Unlike Bubbles, she does not use honorifics (which in Japan is very rude.) She makes the occasional reference to the original series by saying "We save the day BEFORE bedtime!."The reason why she is called Powered is because of her hammer weapon since hammers are strong.
