In 2268, Davis was part of the USS Enterprise's search for Harry Mudd within the labyrinth tunnels of Exo III. He joined three other security guards along with James T. Kirk, Spock, Leonard McCoy and Montgomery Scott.
When he and Harlow discovered a group of Ruk androids about to attack the landing party, the guards stopped them with phasers. Kirk borrowed Davis' phaser, then left to search for Mudd, leaving Davis and Harlow to guard four Andrea units. (TOS - New Visions comic: "The Survival Equation")
