Buttercup is one of the Powerpuff girls. She is black-haired and has green eyes and a green dress. Buttercup, though named last, takes part as the middle child. Buttercup's name isn't based on any personality; she was just named that for it starting with a "B" just like her sisters, Blossom and Bubbles. Her personality ingredient is "spice", and she is a smart-mouth. However, in "Cover Up", she shows a softer side. Elizabeth Guttman Daily did her voice.
