Appearance and Personality
Like her sisters, Buttercup has been changed from a small humanoid with no fingers or toes and a large head to an average-porportioned girl. She also sports a more anime-like design, complimented by her colored sailor fuku. Buttercup has become more aggressive, but why is never explained. She also has become friends with 2 other "tough girls", Mandy and Gaz. Buttercup also has a fangirl crush on Sensei Jack.
Powers and abilities
Buttercup has some of the abilities of the other Powerpuff Girls. She can fly, shoot energy beams, and has super strength. She has no special ability, as seen in the canon episode "Nuttin' Special", but she has used techniques her sisters haven't, such as an attack resembling the Power Wave from King of Fighters and the Kamehameha.
Ever since Buttercup was saved by her gym teacher Sensei Jack, she has developed a fangirl crush on him. However, Jack is obviously too old for her.
