The former 'Battlestar Galactica' star will return to the network where she had her breakout role.

One of the stars of Battlestar Galactica is returning to Syfy.

Tricia Helfer has signed on to the cable network's Van Helsing, playing the most iconic vampire of them all: Dracula. She'll appear in the show's fourth season, which is in production and set for a fall premiere.

Season four will also feature Richard Harmon (The 100), Nicole Munoz (Defiance), Keeya King (Jigsaw) and WWE star Big Show, aka Paul Wight. Details of their roles are being kept under wraps for now.

"We are thrilled to welcome the talented Tricia Helfer to our Van Helsing family," said Chad Oakes, executive producer and co-chairman of Nomadic Pictures, which produces the series. "She will be a fierce and unstoppable Dark One as the battle between good and evil reaches new heights."

Van Helsing stars Kelly Overton as the vampire-hunting title character, who leads a band of heroes fighting to reclaim a world overtaken by vampires. The coming season will delve deeper into vampire lore and explore their ultimate goal for the world.

The cast also includes Jonathan Scarfe, Christopher Heyerdahl, Neal McDonough, Vincent Gale, Rukiya Bernard and Aleks Paunovic. Jonathan Lloyd Walker is the showrunner.

The series is part of a Syfy scripted lineup that includes The Magicians, Superman prequel Krypton, Happy, Deadly Class and Wynonna Earp, though the latter is in limbo due to financial issues at producer IDW Entertainment. The network also has Resident Alien starring Alan Tudyk on tap for 2019-20.
