Commodore Travers was a male Starfleet flag officer in the 23rd century. He was the commander of the observation outpost on Cestus III in 2267. Travers was famous for his hospitality. He also had a personal chef, whom Leonard McCoy wondered if he had brought along to the planet. James T. Kirk guessed he probably had, as his rank would have given him the right to do so.
That same year, the Gorn, who regarded Cestus III as part of their space, attacked and destroyed this outpost. Travers presumably died in this attack. After destroying the outpost, the Gorn faked several messages from the commodore to lure the USS Enterprise into a trap. Because of these messages, Captain Kirk and his landing party beamed down and were attacked immediately by the Gorn. (TOS: "Arena")
