You know him as: Bobby Singer, brilliant hunter and cranky drunk, was the Winchester boys' last remaining ally until he died (we assume) in the mid-season finale. Of course, given the nature of the show, that doesn't mean he's not sticking around -- but we wouldn't bet on it.
Why we like him: What's not to like? Beaver has brought incredible dimension and heart to a role that could have easily been a cliche. Only an incredibly skilled actor could make it believable when this character starts rattling off poetry while talking to his demonic doppelgänger. Only Beaver -- no one else -- could have made Bobby's last word to the Winchesters -- "Idjits," -- sound exactly like an "I love you." He will be sorely missed.
Where else you've seen him: A working actor for more than 30 years, Beaver has one of those resumes that goes on forever. Among the highlights are "Deadwood," "Big Love," "John From Cincinnati" and "Harper's Island." He also guest-starred in an episode of "Justified," a role he'll be reprising this coming season.
