6. Hit-Girl (Chloe Moretz), Kick-Ass (2010)
Mindy Macready is 11 years old and loves Hello Kitty and comics - and also has a passion for guns, a potty mouth, and could probably rip out your windpipe if she really wanted to. Her father Damon has trained her to be the ultimate killing machine, and assists Kickass in his fight against crime boss Frank D'Amico after he murders her father. Mindy is cute and cool combined and you don't often hear an 11 year old swearing like a sailor 3 times her age. Swearing to avenge her father's death, Mindy gets a place at number 6 on my list.
