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.
- The two individuals were a study in contrasts: one was dark and shaggy, covered from head to foot with a mat of hair, while the other was fair and smooth-skinned. It is unclear as to which being was Troykis.
