Dee'Ahn was a humanoid who, in 2152, appeared to Commander Tucker and Lieutenant Reed as a beautiful Risian woman, when the two officers spent two days shore leave on the planet Risa.
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 nightclub basement. (ENT: "Two Days and Two Nights")
Dee'Ahn was played by DonnaMarie Recco as a female, and by Geoff Meed without his disguise.
Recco's costume was previously worn by Monika Kusley in the Star Trek: Voyager fifth season episode "Someone to Watch Over Me" and by Dene Doucette in the Star Trek: Enterprise pilot episode "Broken Bow" and was later sold off on the It's A Wrap! sale and auction on eBay. [1](X)
