While characters like Negan (Jeffrey Dean Morgan) and Rick Grimes (Andrew Lincoln) are often the focus of AMC's hit series The Walking Dead, Bob Stookey (Lawrence Gilliard Jr.) is one of the most important side characters. Throughout the show's 11 seasons, which aired between 2010 and 2023, viewers were introduced to a variety of survivors and walkers. While some made a bigger impression than others, they each contributed to the unsettling tone of the series.
