Bubbles is the second member of The Powerpuff Girls Z. Unlike the original, where she is often childish. Bubbles in Powerpuff Girls Z is quite mature, as she act as a mother towards Ken. She is also the ditziest member of the group, who often appears to be a bit clueless, and seems to not completely understand her powers, along with a few things. She is very friendly and polite, but like the other two girls, can too get mad when provoked, and disapproves of crying to get what she wants. She is popular with many boys at her school, but already has feelings for Takaaki, after saving her from boys when she was much younger. Just in the regular show, she has her innocent and gentle personality, and has a love for animals as well as her doll, Otic.
