Marc Singer is joining the cast of CW’s Arrow this season, and fans are already speculating what the arrival of his character, General Matthew Shrieve, means for the show.

Marc Singer To Guest Star On Arrow

Singer, best known for starring in the cult hit The Beastmaster and V, will be making his Arrow debut in episode 14, titled “The Return,” though not much is known about how his character will be introduced into the Arrow universe. It was, however, confirmed that Singer/General Shrieve will appear as part of this season’s main flashback arc, which has been tracing Oliver Queen’s past with ARGUS in Hong Kong. Manu Bennett’s Slade Wilson will also be making an appearance in episode 14.

Who Is General Matthew Shrieve?

In the DC Comics universe, General Matthew Shrieve is the leader of the Creature Commandos. It’s unclear whether or not the Creature Commandos, which consist of supernatural creatures, will be incorporated into CW’s mostly non-magical Arrow. However, in a recent reincarnation of the series, called “Frankenstein: Agent of S.H.A.D.E.,” Ray Palmer, aka The Atom, made an appearance as the head of SHADE’s technology and science division. Ray Palmer, of course, was recently introduced Arrow in the show’s third season as a business and romantic rival for Oliver – Palmer’s future identity as the ATOM has already been hinted at in the show.

Arrow returns from its winter hiatus on Wednesday, Jan. 21, at 8 p.m. on The CW.
