Former Battlestar Galactica star Tahmoh Penikett has joined The CW’s soon-to-debut superhero drama “Arrow”.

For four years you knew him as the heroic Karl “Helo” Agathon on SyFy’s Battlestar Galactica, but this fall you’ll see him in a different light. Penikett will play Tom Salvati, the right-hand man to mob boss Frank Bertinelli (played by Jeffrey Nordling). It’s unclear at this time whether Penikett’s role is recurring or just a guest starring gig. Bertinelli is the main antagonist and will play heavily into stories throughout the season. He’s also the father of The Huntress who will make her first appearance in the sixth episode (played by Jessica De Gouw).

Arrow stars Stephen Amell (Hung, Private Practice) as Oliver Queen, a billionaire playboy turned costumed vigilante. After a violent shipwreck, Oliver was presumed dead for five years before being discovered alive on a remote island. He returns to Starling City to a life he no longer wants. Desperately wanting to make amends for his past actions, as well as right the wrongs of his family and ills of society, Oliver becomes Arrow. By day he’s living up (or down) to the expectations put on him, and by night he’s saving the city from the likes of corrupt organizations and crime bosses. Katie Cassidy, Colin Donnell, David Ramsey and Willa Holland also star.

Arrow premiers Wednesday, October 10 at 8PM.
