Powerpuff Girls Z! Toon Megastars, or as it's called in Japanese Demashita! Powerpuff Girls Z! Toon Mega-Stars (出ましたっ!パワパフガールズZ! トゥーンメガスター Demashita! Pawapafugāruzu Z! To~ūnmegasutā), is a sequel series in which not only the Powerpuff Girls appear, but other Cartoon Network characters as well. It features characters from shows such as Codename: Kids Next Door, Dexter's Laboratory, The Grim Adventures of Billy and Mandy, etc. Like the previous series, any characters who were not originally teenagers will be teenagers.
- Numbuh 5/Abigail "Abby" Lincoln-a tomboyish girl who has become Buttercup's best friend. She's able to transform when her friends are in pain, or at will. She transforms due to an effect from one of Numbuh 2's inventions. When not transformed, she uses standard hand-to-hand combat and 2x4 Technology.
- Numbuh 2/Hoagie P. Gilligan-a very smart, savvy boy who supplies 2x4 Technology. Numbuh 5 has a crush on him.
- Dexter-also a smart boy, he is friends with Numbuh 2 and helps him with inventions. He has no love interest. For an unexplained reason, he has a Germanic accent.
- Mandy-even though she has a dark personality and is a bit of an anti-hero, Mandy is actually quite good at heart. She transforms when attacked, or at will. Her transformation comes from a blast from her friend Grim's scythe.
- Billy-a stupid boy. It is thought that Mandy might like him, but she usually prefers picking on him.
- Grim-the skeletal incarnation of death himself. He has suprising power, and is responsible for Mandy's powers.
- Leshawna-a teenage girl with a fiesty personality. She transforms at will. She likes a boy named Harold. Her transformation is due to toxic radiation on the island of Wawanakwa.
- Harold-a red-headed nerd. He actually convinced the Rowdyruff Boys to join their side, and it worked.
- Father-a villain who can shoot fire. He usually wears a suit that makes him appear as a silhouette.
- Mandark-Dexter's rival. He seems like a nerd, but he shouldn't be underestimated; he can be manipulative, cunning, and almost merciless and unforgiving.
- Heather-a spoiled girl who hates losing. She has a transformation, and it is triggered when she schemes up a wicked, nasty idea.
- Harold, Leshawna, and Heather are from the Total Drama series, which in reality hasn't been aired in Japan. In my mind, it airs in Japan before this comes out.
- Even though most characters' ages have been risen, Harold, Leshawna, and Heather's ages remain the same.
- These are only officially confirmed new characters. Others might be added later.
- The Rowdyruff Boys are now on the PPGZ's side, yet still tend to be mischeivious. It's sort of a neutral territory.
- Despite the fact that Leshawn, Mandy, and Numbuh 5 transform much like the PPG and have outfits similar to them, they are not considered PPG.
- The reason Numbuh 5, Leshawna, and Mandy can transform is not only due to their listed reasons, but because there were slight traces of Chemical Z in each source.
