4. Carol The Badass
When The Walking Dead first hit our screens Carol was the downtrodden, abused wife of a no good redneck. Following his gruesome demise at the hands of a throng of undead flesh eaters Carol developed into a much stronger character who has over the course of 4 seasons become one of the most important figures in the group of survivors. Carol's decision to 'murder' infected Karen and David was in her eyes for the good of the group but instead of thanks Carol was instead given the boot and left to fend for herself. The Carol of old would certainly have been out of her element and guaranteed zombie chow within minutes of Rick buggering off back to the prison without her but the Carol of season 4 is world's apart and we're not so sure she'll have as much trouble as you might think. She has the killer instinct, can handle herself and by this point is an adept killer with potentially hundreds of kills under her belt given her knack of sticking the undead in the eyes since making it to the prison. So when Carol returns we foresee an even tougher version of the woman who drove away in 'Indifference'. It could be like the second coming of Michonne but with less pet zombies. Could you foresee her leading her own group of survivors?
