8. Ma-Ma (Lena Headey), Dredd (2012)
Ma-Ma, aka Madeline Madrigal is the leader of one of the toughest gangs in Mega City One - the Ma-Ma Clan. A prostitute turned drug lord, Ma-Ma killed her pimp, founded her gang and then proceeded to take over the entire Peachtree Block, wiping out 3 rival gangs and giving her complete control. Whether you like her or not, you cannot deny that Ma-Ma is one strong woman, and her attitude and drive definitely gives her a spot in cinema history as one of the coolest female characters.
