Mot was a civilian Bolian hairdresser who worked in the barbershop aboard the USS Enterprise-D.
Mot provided the hairpieces worn by Data and Captain Picard when they traveled to Romulus in 2368 disguised as Romulans in an attempt to locate Ambassador Spock who was on the planet seeking dialog toward re-unification of the Vulcan and Romulan people.
When Lieutenant Worf came in for a trim, Mot recommended that Worf start using conditioner. Mot's scissors produced a reaction in Worf that led Worf to discuss these feelings with Troi and Riker.
When Captain Picard was captured by Kelsey and her band of mercenaries in 2369, he told them that he was Mot, the ship's barber.
