Girls Who Can Kick Your Ass: Hitgirl (Chloe Grace Moretz, Kick-Ass)

No mass murderer is as adorable as Hitgirl. The tyke-sized superhero in punk attire moves like a pinball when dispensing baddies while recycling through her arsenal with panache. Without a single reservation about decapitating limbs or spraying blood all over the screen, Hitgirl is the only character on this list that can make you say "how cute" and "how gross" at the same time.
