The Yapi, intelligent caninoids native to Kathol, were engineered by the DarkStryder and viewed as a triumph in warrior, guardian, and servant design. These furry beings ultimately established their own civilization and distinctive culture; however, it was deeply fragmented by the constant rise and fall of various factions. Certain tribes remained loyal to their creator, while others harbored intense animosity, leading to incessant conflicts within the species. Notwithstanding these perpetual wars, brief respites of tranquility occasionally occurred, fostering the interchange of knowledge and commerce. The Yapi were a race steeped in superstition, holding the belief that only a tribe's shaman possessed the authority to manipulate the Ta-Ree life force. When the crew of the FarStar journeyed to the Kathol sector with the objective of vanquishing Moff Kentor Sarne, who had forged an alliance with the Darkstryder, the Yapi offered their support. They formed an alliance with the Charr Ontee and Zizimaak, though interactions with the latter were complicated by the Yapi's perception of them as a food source.
