In 2366, Tog was present at the Trade Agreements Conference located at Betazed that year. At a reception aboard the USS Enterprise-D, he became infatuated with Betazoid Ambassador Lwaxana Troi. Following numerous rejections by the ambassador towards his advances, Tog kidnapped Lwaxana, as well as Starfleet officers Deanna Troi and William T. Riker. Tog's intentions were to persuade Lwaxana to join a partnership so as to exploit her telepathic abilities in trade negotiations. She played along and relaxed Tog while Riker and Deanna worked to escape and send a message to the Enterprise. Tog was confused when Jean-Luc Picard attempted to win back Lwaxana, and released her when Picard threatened to fire on Tog's ship. (TNG: "Ménage à Troi")
While trapped in a turbolift aboard Deep Space 9 in 2369, Lwaxana told Odo about her experience aboard a Ferengi cargo ship. Initially, she described the experience as "dreadful," but clarified it had actually been "mildly lamentable," all because of Tog, whom she characterized as a "loathsome DaiMon." She later particularized him as "slightly repulsive" but specified that he did have "a certain charm, in an insufferable sort of way." Lwaxana went on to explain to Odo that Tog had been "totally at the mercy of his uncontrollable passion" for her, which had also incorporated "some negligible commercial interest involved," all of which she found to be "quite touching, in a way." She mentioned the moment when she had "made love with him." (DS9: "The Forsaken")
Tog was played by actor Frank Corsentino.
This character was called DaiMon "Tarr" in the second draft script of "Ménage à Troi".
"Tog" was also the name of the Ferengi character played by Al Franken in the Saturday Night Live skit Love Boat: The Next Generation, a parody of both The Love Boat and Star Trek: The Next Generation, when Patrick Stewart hosted.
