Cornering Birkin in his laboratory, HUNK initially tried to reason with the scientist, but Birkin was adamant in not surrendering his life's work. As William attempted to back away from the agents, he accidentally knocked over a metal container. The sudden noise caused the second U.S.S. member to shoot William with a burst from his Submachine Gun.
HUNK berated his subordinate for the action, which could have damaged the sample case, leaving the virus potentially damaged and irretrievable. He collected the entire case and left the lab with samples of the G-virus, as well as the t-Virus, which were also present in Birkin's case. With their main objective complete, the team headed through the tram into the sewer to reach their extraction point.
While en route, they were confronted by Birkin, who had injected himself with a sample of the G-virus shortly after being shot. Birkin, now a horrifically mutated monstrosity named "G", pursued Alpha Team and exacted revenge. During the fight, the case was spilled. After killing HUNK's team, G consumed the G-virus samples and crushed the t-Virus samples under his foot. Sewer rats became infected by the t-Virus spill and spread the virus throughout the city via the sewer network, which spread into the water supply.
Only HUNK and Miguel survived Birkin's attack. Unmoved by his comrades' demise, he focused his efforts only on returning a surviving sample to his superiors. At least a week after the confrontation with William, HUNK managed to contact his team's helicopter pilot and arranged to meet him on the roof of the police station.
After making his way through the precinct, HUNK reached the roof, set off a flare, and was extracted by helicopter and successfully escaped Raccoon City.
HUNK was assigned on a mission to deliver a special container from Umbrella's transport terminal in the Antarctic to Rockfort Island. The mission was controversial in that Alfred Ashford, the island base's commander, refused to detail exactly what was inside the crate. This, to HUNK, posed a clear safety and security hazard as his unit would have been unprepared to handle what potentially was inside.
Following the 2003 fall of Umbrella, he became a legendary mercenary and devized the original fighting style CQBZ (Close Quarters Quarantined Battle Zone) as well as equipment and custom weapons formulated for it such as the Zombie Beil, Zombie Eisen, Zombie Jammer and the Bite Guard.
HUNK is shown to be a cool and cunning fighter as he is able to maintain his cool even in the most extreme situations, such as when he fought his way through the Raccoon Police Department to be evacuated before it was eradicated. He is also highly skilled in combat, as it is shown he can take on or at least survive some of the most powerful B.O.W.'s like the G-virus infected William Birkin.
HUNK's mission takes priority over everything else, showing no remorse for human loss of life during any incident he has been called in. This, he claims, is how he has never failed a mission: "Death cannot die."
He is one of the most formidable characters in the series as well, showing to be able to escape harm from dangerous situations, surviving even when close to death and often returning alone, which is how he got his nickname "Grim Reaper HUNK."
