7. Hit-Girl (Kick Ass)

From the mouth of babes and all that. The genuine superhero of Kick-Ass (the film about people pretending to be superheroes) is in fact, potty-mouthed adolescent Mindy McCready (Chloe Moretz) - an ass-kicking, f-bomb laying martial arts expert all at the grand old age of 11. Hit-Girl is not one to get phased by a sticky situation. Mowing down scores of trained mafia men, and almost always having a smart saying to follow up with, she really is the kind of superhero you can rely on. Still, for the more sensitive viewers among us, the frequent use of profanity, including a well placed 'see you next Tuesday' might have people feeling a little put out.
And to demonstrate my point... "I'm just f***ing with you Daddy! Look, I'd love a Benchmade model 42 butterfly knife." - Its the relief that washes over Nic Cage's face once his daughter says this that's priceless!
