Sergeant Marcus is a character in the film Jason X, in which he is portrayed by Markus Parilo.


In 2010, Marcus accompanies Doctor Aloysius Bartholomew Wimmer and a quartet of four other soldiers through the Crystal Lake Research Facility, planning to move the captive Jason Voorhees from the facility to another one better equipped to examine him. On the way to area holding Jason, Marcus, Wimmer and the soldiers are confronted by head researcher Rowan LaFontaine, who demands to know why Wimmer is at the facility so early, as she has yet to cryogenically freeze Jason and ready him to be moved. After Wimmer explains to Rowan that he has received permission from the military to transport Jason alive, he has Marcus reassure the obviously distressed Rowan that the soldiers in his company can handle Jason if he escapes, before moving on.


Marcus' death at the hands of Jason Voorhees.

Arriving at Jason's holding area with Wimmer and the soldiers, Marcus removes the blanket covering what he believes to be Jason, only to find a dead soldier in the killer's place. As Marcus, Wimmer and the soldiers stare in shock at the dead soldier, Jason attacks them from behind and murders the four soldiers and the fleeing Wimmer, knocking Marcus to the ground during the process. Minutes later, when Rowan passes Jason's holding cell, Marcus is violently thrown through the door in front of her. When Rowan rushes to him Marcus tells her to run before dying. 

He is Jason Voorhees' 117th victim.
