His devious plans and his rivalry with the girls make for interesting stories in fanfic.
In some fanfics, the Professor is a popular character to focus on. His role as the creator of the Powerpuff Girls Z can be explored further. Maybe there are secrets about their creation that he hasn't told them yet.

This gives a new dimension to his character in fanfic.

The main characters would definitely include the Powerpuff Girls Z. Blossom Z, Bubbles Z, and Buttercup Z are the sweet but powerful defenders of Townsville. They have different personalities and powers that make them unique.

Some of the supporting characters like the Mayor or Ms. Bellum can also gain popularity in fanfiction. They might be given more backstory or a more important role in a particular story.
