In a story from The Hollywood Reporter, Robert Knepper (Prison Break) is the new bad guy on NBC's Heroes next season.

In no less than six episodes of the series' fourth season, Knepper will play the role of Samuel, a charismatic but evil man with a twisted sense of humor, who will place himself in the lives of all heroes.

Heroes is set to come back in the fall for what is being described as a "Lost-style all-original run" at 8 p.m. on Mondays.
