A Malon crewman who escapes his radiation-flooded freighter with Controller Fesek in 2375 and returns with a Voyager away team, only to be fatally attacked in the contaminated lower decks.
Pelk appears in the fifth-season Voyager episode Juggernaut, played by Lee Arenberg. He serves under Controller Fesek on a Malon export vessel carrying trillions of litres of toxic waste, and is first seen showing off a toy model of the ship he has built for his young son.
When the freighter suffers a catastrophic theta-radiation leak, Pelk and Fesek are the only two crew rescued by Voyager. Both agree to guide Chakotay, B'Elanna Torres and Neelix back aboard to prevent an explosion that would poison the whole sector.
Pelk is superstitious and insists that the Vihaar, a monster from Malon legend, lives in the tanks. He is attacked by an unseen figure while working alone and dies of his injuries, a death later traced to the disfigured core labourer Dremk.
