Captain S'slee (also known as S'alath or S'salk) was an officer of the Gorn Hegemony's military in 2267. He commanded the MA-12-class cruiser Gress'sril that destroyed the Federation outpost on Cestus III. S'slee was forced by the Metrons to battle Starfleet Captain James T. Kirk in order to settle their differences. Kirk astounded all by besting S'slee and then letting him live, refusing to allow the Metrons to goad him into committing what he saw as murder. This impressed both the Metrons and the Gorn, and S'slee would often recount the honor of the combat and take pride in the scars from Kirk's cannon-blast. S'slee grew old and eventually began to suffer the effects of old age on his mind. He devised an elaborate death for himself, living out the end of his days on a remote, deserted planet fighting holograms depicting Kirk.
