Momoko Akatsutsumi (赤堤ももこ Akatsutsumi Momoko) Blossom/Hyper-Blossom (ハイパー・ブロッサム Haipā BurossamuSeiyu: Emiri Katō - English Dub Voice: Nicole Bouma.

Blossom is the first member of the Powerpuff Girls Z squad. She transforms using the phrase "Hyper Blossom" and fights villains with a yo-yo. Like the original, she is the self-proclaimed leader of the team. She is a bit boy-crazy. She is very familiar with the maho shōjo genre, along with some typical anime/super sentai concepts and is famous for being a "hero maniac" in school, especially by Buttercup. Blossom also has a strong appetite for candies and other sweets, and spends much of her time snacking. Because of this, most of her attacks are named after food. In addition, she dislikes vegetables and is afraid of bugs and dentists. Although she can be easily distracted and has been known to whine, Blossom tries her best to protect New Townsville, lead the girls, and help her friends regardless of her situation. Often she can be very clever and crafty when needed, usually being the first to come up with a plan to trick or defeat villains/monsters. She is the elder daughter of Hachizou and Kakio Akazutsumi and has a younger sister named Kasey. She is represented by hearts. She dreams of being married in the future.
