One of two killers sent to Deep Space 9 by the Orion Syndicate boss Draim to retrieve a data crystal and dispose of the woman it was meant for.
Traidy appears in A Simple Investigation, played by Nicholas Worth.
In 2373 he and his partner Sorm arrive on the station ahead of Arissa and intercept Tauvid Rem, the courier bringing her a data crystal. They kill him in his quarters but fail to find the crystal. Traidy, the more talkative of the two, then sets about tracking Arissa, who has come to the attention of Odo after trying to break into the station's computer.
The pair report to Draim by subspace and are told to finish the job. Their final attempt on Arissa's life, made when she tries to hand over the crystal in exchange for her freedom, is foiled by Odo, who has fallen in love with her and has followed her to the meeting.
