Knox was a Human male of the mid-23rd century.
Knox had dealings with the Orion woman Leata and visited her at Club Aknar, where he provided her with the location of Tellarite Administrator Muso, though he feared for his safety if the information was traced back to him. He was quite nervous about telling Leata, even under the sway of Leata's charms. (ST comic: "Alien Spotlight: Orions")
