One of a pair of thieves who appear to Tucker and Reed as alluring women in a Risan nightclub and then rob them at gunpoint.
Dee'Ahn appears in Two Days and Two Nights alongside a partner, Latia. Tucker and Reed, determined to meet someone during their shore leave on Risa, are delighted when the two join them at a club and offer to show them the gardens below.
The gardens turn out to be a cellar. There the pair drop their disguise, revealing themselves as male aliens able to change their appearance, and demand valuables.
Finding the officers have almost nothing worth taking, the thieves stun them, strip them to their underwear and leave them tied up for the night, an episode the two men are in no hurry to describe when they return to Enterprise.
