*Mos Def has finalized a deal for a multi-episode arc on the sixth season of Dexter, according to the Hollywood Reporter.

The actor/rapper will play a hardened ex-con who claims to have found religion yet seems to continually find himself surrounded by violence. Michael C. Hall’s Dexter will reveal the truth of who he really is.

Production on the sixth season of the Showtime drama thriller begins in June with an eye toward a fall premiere.

Mos Def joins Colin Hanks — who will appear in all 12 episodes — as one of the upcoming season’s villains. Hanks will play Travis, Dexter’s main nemesis and a highly intelligent ancient artifacts expert who is linked to a series of grisly murders in Miami.

At this point it unclear in how many episodes Mos Def will appear. But he is one of multiple recurring characters who will populate the show after the dispatching of season five guest stars including Jonny Lee Miller, Julia Stiles and Peter Weller.
