Dee'Ahn was a humanoid who, in 2152, when the two officers spent two days shore leave on the planet Risa, appeared to Commander Tucker and Lieutenant Reed as a beautiful woman. She and her friend, Latia, set up a date with Tucker and Reed, only to reveal themselves as two male thieves who were in disguise. They robbed Tucker and Reed, leaving them tied up in a cellar of a nightclub. (ENT: "Two Days and Two Nights")
