3. Carol Peletier
A battered wife, a grieving mother, a good-in-the-clutch friend, a stone-cold killer with a creepily pleasant facade – Mrs. Peletier has been a source of genuine pathos and some dark comedy, made all the more potent by casting-director-turned-actor Melissa McBride's mercurial performance. It’s no surprise that the TV version has long-outlived her comics counterpart, who killed herself instead of getting stronger; McBride has helped turn this once peripheral character into a major part of TWD, whether she's putting on a Susie Homemaker act as a front or rescuing her comrades from certain Terminus doom. A recent crisis of conscience has sidelined Carol some over the course of the past year, but she's always going to be an all-star just based on her arc in the first five seasons. And while the character is in uncharted narrative territory right now, that just makes it all the more exciting to see what will happen to her next.
