I watched some of the Powerpuff Girls Z episodes back when I was middle school and it became a surprise for me that there is a Magical Girl Anime series based on the Powerpuff Girls. I haven't gotten the chance to watch the rest of the episodes since school kept me busy at the time, but maybe when I get the chance I'll rewatch the series again. I have admit that the changes in Powerpuff Girls Z were unexpected such as, the girls not being sisters and the professor having a son.
