Buttercup of the Powerpuff Girls is the toughest of the three. Her personality ingredient is spice, her signature color is green, and she has short black hair in a flip. She is a tomboy who loves to get dirty, fights hard and plays rough; she does not plan and is all action. Buttercup is the only Powerpuff Girl without a unique super power (aside from being able to curl her tongue as shown in the episode "Nuthin' Special"). McCracken originally wanted to name the character "Bud" until a friend suggested the name Buttercup.
Buttercup is voiced by E. G. Daily.
