...Six Creepy Killers.

Murderers, psychopaths, homicidal nut-jobs, and guys that like to eat fingers. Killers, they come in all shapes and sizes, all forms, and they're all over TV. We love to hate them and in some cases we hate that we love them. But you can't avoid them because more often than not, they lead to some great storylines on many of our favorite shows. Here's a look at some of the big ones from 2006.

1.) Sylar [Heroes] - Mild-mannered watch maker turned super-powered brain craver, Sylar has been removing the pink organs from folks on Chandra Suresh's list on Heroes all season long. He looks calm in that picture, but that was before he grew in the scrappy beard and donned a trench-coat. His ability to absorb the powers of those he kills is creepy enough, but actually seeing him get angry is definitely unnerving. Just look at what he did to Eden in the show's mid-season finale. I wouldn't recommend standing in front of a plate-glass window if this guy is on the other side of it.

Catherine Bell (JAG) and Gary Cole (aka 'Lumbergh' on Office Space) have joined the cast of the CBS pilot Company Town, a drama about government agents who live in the same neighborhood. Already on board for the pilot are Sherry Stringfield (ER) and Blair Underwood (LA Law). You don't have to wait for next fall to see Cole on television, he'll reappear on some of the final episodes of The West Wing.

Mercedes Ruehl has joined the untitled Paul Reiser comedy pilot for CBS, about a man who takes over the family car dealership in Queens, NY. In 1991, Ruehl won an Academy award for her supporting role in The Fisher King. Ruehl joins castmates Bobby Cannavale (Will & Grace) and Hector Elizondo (Chicago Hope).
