"Being Human" alum Jon Cor has signed on to play weapons trainer Hodge Starkweather in ABC's "Shadowhunters," Variety reports.

Based on Cassandra Clare’s bestselling “Mortal Instruments” novels, “Shadowhunters” centers on Clary Fray (Katherine McNamara), who discovers on her 18th birthday that she descends from a long line of Shadowhunters, human-angel hybrids who hunt demons.

When her mother is kidnapped, Clary is drawn into the world of demon hunting with the mysterious Jace (Dominic Sherwood), his fellow Shadowhunters Isabelle (Emeraude Toubia) and Alec (Matthew Daddario), and her best friend Simon (Alberto Rosende). Starkweather (Cor) acts as a mentor to the younger Shadowhunters and helps train Clary to fulfill her destiny. Isaiah Mustafa will also star as Luke Garroway, a former Shadowhunter-turned-werewolf who uses his monster fighting skills for the NYPD.

Produced by Constantin Film, “Shadowhunters” begins production this month in Toronto.
