Moody was a male Human Starfleet crewman who lived during the mid-23rd century. He served in the command division aboard the USS Enterprise from 2266 to 2268 under the command of Captain James T. Kirk, during his historic five-year mission.
In 2266, he became infected by polywater intoxication, bringing about a romantic interest in Yeoman Rand. Inspired by the lyrical ship-wide broadcasts of Kevin Riley, Moody persistently serenaded Rand with his own rendition of the song "I'll Take You Home Again, Kathleen." (TOS: "The Naked Time")
