Troykis was an individual who was imprisoned in Area 347 on a planet in Subu territory in the 24th century. He was challenged by another prisoner named Loord the Noarkan, who was determined to depose him as champion in combat. Other prisoners took bets on their fighting. However, both Troykis and Loord were killed (while still in locked combat) when Subu guards put a stop to their fighting by incinerating them and any other prisoners close by. (VOY novel: Pathways)
