CBR brings word that former Beastmaster star Marc Singer has joined the cast of The CW’s “Arrow” as General Matthew Shrieve, who in the comics is the human leader of the “Creature Commandos,” a military unit consisting of Frankenstein’s monster, a werewolf, a vampire, and a gorgon. The official character listing for Shrieve reads as follows:

“In the DC Comics, Matthew Shrieve is the leader of a group known as the Creature Commandos. In ‘Arrow’ he will play a significant role in the latter portion of the season’s flashback storyline.”

Singer will make his debut in the 14th episode of the series’ third season which will be a recurring role. No stranger to genre roles, Singer is most well known for headlining the three “Beastmaster” films but also had roles in the sci-fi favorite “V” as well as the “Planet of the Apes” TV series and “Batman: The Animated Series,” where he provided the voice of Kirk Langstrom, AKA Man-Bat.
