A Ferengi officer who leads the landing party sent to Delphi Ardu IV in The Last Outpost, where he confronts Riker's away team and argues his people's case before the guardian Portal.
Letek is a Ferengi officer serving under DaiMon Tarr, and the leader of the three-man party beamed down to Delphi Ardu IV in the first-season episode The Last Outpost. The encounter is the Federation's first face-to-face meeting with the Ferengi.
With Mordoc and Kayron he ambushes Riker's away team using energy whips, intending to blame the humans for the force that has paralysed both ships. When Portal, the guardian of the dead Tkon Empire, awakens, Letek tries to persuade it that the humans are the true barbarians, pointing to their habit of clothing their females.
Portal is unimpressed, and it is Riker's composure that wins the release of both vessels. Letek and his men are sent back to their ship.
