You know him as: Carl Grimes, the youngest member of a badass band of zombie apocalypse survivors (unless you count his newborn baby sister)
Why we like him: In the first two seasons, Carl was a kid in need of protection. He'd wander off, get himself shot, accidentally unleash a zombie that killed one of his fellow survivors (Dale). And through it all, Riggs was pretty solid by TV child actor standards. But he's really blossomed this season as "The Walking Dead" has amped up the action and Carl has become a full-on warrior. He's every bit the product of his no-nonsense dad Rick (Andrew Lincoln) and late mother Lori (Sarah Wayne Callies), who left him with words of wisdom that inspired a steely resolve ... and eased the pain of the ugly necessity of shooting her in the head before she turned into a walker.
Where else you've seen him: "Walking Dead" is his first major role, but Riggs did appear in the 2009 Robert Duvall/Bill Murray indie "Get Low."
