In the year 2364, Letek was one of the first Ferengi to be encountered by the United Federation of Planets. Letek's team incapacitated a team from the USS Enterprise and later negotiated with a portal of the Tkon Empire. (TNG episode: "The Last Outpost")
By 2372, Letek had risen to the rank of DaiMon and commanded the Preekon. In that year, Letek was contacted by Benjamin Sisko and Quark from the USS Defiant who asked him for an audience with Grand Nagus Zek. Quark thought Letek's bottom row of teeth looked horrible, while Jadzia Dax thought he seemed familiar. Letek later transported Quark from the Defiant to the Nagal Residence on Ferenginar. (DS9 novel: The 34th Rule)
- Letek was played by Armin Shimerman in "The Last Outpost".
