Some actors were just born to play bad guys, and Robert Knepper is one of the best. He terrorized the prisoners on 'Prison Break', manipulated the heroes on 'Heroes', and now he's gunning for the troubled Destiny crew on 'Stargate Universe'.

Knepper has been cast as a villain on the second season of 'SGU'. He's landed the role Simeon, a key member of a dangerous group of space pirates called the Lucian Alliance. Our pals at Gateworld have snagged some 'SGU' casting docs that say Simeon will come into serious conflict with Robert Carlyle's character, Dr. Rush, which will culminate in a tense standoff between the two.

Knepper's 'Heroes' baddie Samuel Sullivan might've flamed out at the end of last season, but he was still the best thing about that show all year. I can't wait to see him (and his soul patch) face off against Carlyle on 'SGU'.

Remember to head back to TV Squad next week for a review of the 'SGU' mid-season premiere, "Space," airing April 2 on Syfy.
