In the galactic standard year of 33 BBY, a member of the Yuuzhan Vong was apprehended and subsequently transported to the Cog Hive Seven prison facility. This Yuuzhan Vong, whose body was heavily modified with various implants, rapidly ascended to the position of champion within the prison's regular gladiatorial contests. Given that the extra-galactic Yuuzhan Vong species remained unknown to the galaxy during this time period, the prison administration was unable to identify the warrior's species using their existing databases. Despite this, some of the guards speculated that the prisoner was a female. Wielding an amphistaff, this warrior secured victory in every match for a consecutive six months, until facing Darth Maul, a Sith Lord who had recently arrived. Maul, operating undercover as the criminal "Jagannath" as part of a mission on Cog Hive Seven, engaged the Yuuzhan Vong in combat. After a difficult fight, Maul brutally killed the Yuuzhan Vong, thus taking the title of prison champion.
The Yuuzhan Vong prisoner made an appearance in the 2014 novel Maul: Lockdown by Joe Schreiber.
