- "I know. Okay, lets circle down and...Oh shit."
- ―Stefopoulos (from Predator: Life and Death)
Stefopoulos was a member of the United States Colonial Marine Corps. He was part of a 31-Marine platoon under the command of Captain Paget, aboard the combat ship Hasdrubal, that landed on the planet LV-797 under investigation of potential asset-strippers.
He was killed by the Hive Wars Predator after it ambushed him and his squad from behind, impaling him.
Biography
Stefopoulos was part of the combat ship Hasdrubal on a mission to prosecute any potential illegal prospectors on the planet, LV-797, nicknamed Tartarus. The Hasdrubal was serving the interests of the Weyland-Yutani Corporation, which had scheduled the planet for terraforming.
Upon landing on the planet, the platoon encountered a Seegson excavation site, soon after recovering asset-stripper Laurence Goode, sole-survivor of a massacre at the hands of unknown assailants. Captain Paget ordered Sergeant Roth's squad to search for any remnants of Goode's crew, and the latter had Stefopoulos, alongside Rucker, Lee and Bonito 'sweep the left'.
Death

During the patrol, as Stefopoulos contacted Roth to inform him that nothing was found, the Hive Wars Predator suddenly appeared behind him. Before anyone else could react, he was swiftly impaled through the back as the other Marines turned in shock.
