Maggie Greene hasn't had an easy go of it in the apocalypse. She first appeared in the second season as a young girl trying to survive on a farm with the rest of her family. Over the course of the show, a lot has happened to her, but she remains steadfast and able to carry on. Not only has she had to endure the deaths of everyone in her family, but many of those deaths happened in front of her and mark some of the most graphic in the series.
Maggie is one of the series' leading badasses, right alongside some of the show's biggest characters including Daryl, Rick, and Carol. She has shown her ability to deal with walkers, living humans, and even bureaucracy.
Over the course of the show, she has racked up quite a number of kills, but her strengths don't only lie in her ability to dispatch the occasional walker, it's her leadership and resolve in the face of horrific loss and brutality that makes Maggie one of the best characters on The Walking Dead.
