21. Tyreese Williams
This fan-favorite from the comics took longer than expected to arrive on TV, but once he showed up, Tyreese (played by The Wire's Chad L. Coleman) served the show well during his three seasons. His story arc saw him go from being a strong, silent sidekick to experiencing his own personal tragedy – and then finding himself on the road with Carol, the woman partly responsible for the death of his lover. His eventual sloppy shiffling off this mortal coil continues to haunt his sister Sasha, who now finds herself navigating the apocalypse without her burly, tender-hearted protector.
