My favorite super-heroines are the Powerpuff Girls. One, because I used to watch the cartoon back in the day (my two best friends and I nicknamed each other after them - I was Bubbles, and yes, we followed the whole "girl power" movement), and two, because they simply kick ass. Buttercup, Blossom, and Bubbles (left to right) from the outside look like sweet, innocent, harmless, doe-eyed little girls. But...deep down inside they are hell-raising, fighting machines with super powers! I just love the combination of "sugar, spice, and everything nice", power and "fighting crime and the forces of evil". These girls rock!
