Buttercup is the tomboy of the Powerpuff Girls. Her personality is "spice", & her signature color is light green. Buttercup has short black hair in a flip with a small triangular part on her forehead. She has lime green eyes, and dresses in lime green. Referred to in the ending theme as "the toughest fighter", she is the group's tough one and is easily enraged. Sometimes this, and her agression gets the better of her, making her a little reckless and stubborn, she also showed a greedy side. She has shown these sides, and a softer side in several episodes. She posseses a violent and mean streak not displayed by her sisters. While Buttercup doesn't seem to have any special superpower different from her sisters, she is physically the strongest of the three girls. During the birth of the girls, she was initially shown to look extremely happy with wide eyes and an open mouthed smile up to the point where, last of the three girls, Professor Utonium said he would name her Buttercup because, like both of her sisters' names, it also begins with a B. Once she heard this, Buttercup immediately crossed her arms and pouted, "Hmph!" This may explain her tough nature. Her special abilities she displays are Tornado Generation, Ball Blast, Black Hurricane, Green Laser Beams, Energy Orb, Thunder Clap, & Fireball. The Powerpuffs standard powers they all share are flight, super strength, and lazer vision. Buttercup is most definitely a tomboy. With this trait, it could have represented her aggresive and violent nature. Buttercup is the only Powerpuff Girl capable of defeating any villain in Townsville all by herself. Out of Buttercup's whole list of dislikes, her greatest dislike is losing. She will always refuse to admit defeat, unlike Blossom and Bubbles.
