Lieutenant Painter was a male Human Starfleet officer who lived during the mid-23rd century. He served in the command division aboard the USS Enterprise under Captain James T. Kirk, during Kirk's historic five-year mission. In 2267, Painter was assigned as one of the ship's helmsmen.
Like the rest of the Enterprise crew, Painter later fell under the influence of the Omicron spores and mutinied, though he eventually recovered thanks to a subsonic transmitter. (TOS: "This Side of Paradise")
