Quincy Tsardikos was a drafted medical officer of the UNSC Marine Corps, who was stationed aboard the prowler UNSC Red Horse. He had little combat experience and easily panicked in situations.

Skirmish on the Mona Lisa
Tsardikos took part of amission in locating the debris field of Installation 04 as a part of the UNSC Marine contingent aboard the UNSC Red Horse. After three days, Commander Tobias Foucault, the captain of the Red Horse, was able to retrieve a signal coming from a shuttle, which, once opened, revealed a man surrounded in his own blood. The man died of his wounds, leading Tsardikos to perform an autopsy. He and the other Marines followed Sergeant Zhao Heng Lopez to board the prison ship Mona Lisa. Unknown to them, the freighter had been taken over by the Office of Naval Intelligence and the operative Major John Smith, who started conducting secret researchs with xenomorphs.

Following a short firefight against three unarmored sangheili in the cargo bay of the Mona Lisa, Tsardikos was assigned to the team of Corpsman Ngoc Benti, tasked with destroying the ship's database in the engine room. The team moved towards the recycling plant, where they were attacked by multiple xenomorphs. While being pursued by the xenomorphs, Tsardikos froze in fear and stared at the xenomorphs without firing his weapon. He fell behind and was quickly taken by the xenomorphs for harvesting.
