A Malon core labourer aboard a stricken waste freighter in 2375, horribly disfigured by theta radiation, who sabotages the ship in revenge and is mistaken for the mythical monster called the Vihaar.
Dremk appears in the fifth-season Voyager episode Juggernaut, played by Scott Klace. He is a core labourer on a Malon export vessel, one of the workers who accept a short, dangerous career beside the theta-radiation tanks in exchange for high pay.
Heavily irradiated and scarred, Dremk survives in the contaminated lower decks after the ship is abandoned. He is the true cause of the disaster, having sabotaged the freighter out of rage at a society that uses up labourers like him and looks away. The surviving crew take his attacks for the work of the Vihaar, a creature of Malon folklore said to haunt the tanks.
B'Elanna Torres confronts him in the control room, tries to reason with him and finally has to strike him down so that the ship can be steered into a star.
