She's practically a co-lead with Rick on the page yet became a surprise casualty in the show's third season. She had a good run though, with Laurie Holden playing her as shrewd enough to see through the Governor's beneficent facade, and friendly enough to bring the lone wolf Michonne into the fold. Even now, her steeliness and wits are missed.
The closest Rick came to an actual nemesis was his former colleague in the King's County Sheriff’s Department. Unhappy at being usurped, Shane consistently undermined his friend at every turn, becoming the first ongoing TWD character to insist that the only way to make it in this new world is to leave all scruples and sentiment behind. And love him or hate him, his return as a walker remains one of the series' more memorable moments.
His death at the start of Season Seven has been the last straw for many TWD fans, several of whom have stopped watching the show because of it. Prior to his murder, the ever-upbeat ex-delivery man had been in the series as long as Rick, and though he'd seemed to be dead multiple times before, our man Glenn somehow persevered each and every time ... except the last time. His final fate appears to mark a turning point in the plot, signaling the end of the survivor's can-do spirit and the dawn of despair. For many, Steven Yuen's character was the heart and soul of the show. R.I.P.
He's ultimately remained the compelling, charismatic character that he was when we first met him. He represents The Walking Dead's conflicted core, the conduit that writers use to explore both the hard choices a successful survivalist has to make and what it costs people when they become unfazed by death. The role has also provided the show with too many unforgettable moments to count. To grasp what the series is really about, it's necessary to understand what the head of the Grimes family is going through as the show moves from one test of will to the next.
From the moment she appeared on screen (katana sword at the ready, stoic-gunfigther look on her face, wandering the land with two jawless walkers shackled to her) Michonne has been The Walking Dead’s ultimate bad-ass. She's also adapted well to living in a group, and has even started to draw on her pre-apocalypse past as a mother and an academic to start thinking about how best to rebuild society. This character represents this series at its best. Michonne hasn’t lost touch with her humanity. And she's a thrill to watch on a killing spree.
