The Torothans are a humanoid species native to the planet Toroth in the Beta Quadrant. The species are divided into clans, with the Torothan clan ruling over all others in what Zobral believed was a ruthless and oppressive manner. Each clan is identified by specific facial markings in the area between the lower lip and the throat. With the exception of these markings, this species appear to be outwardly indistinguishable from Humans.
The Torothans were encountered by the crew of Enterprise in 2152 when they made repairs to a ship operated by Zobral, who subsequently invited Enterprise captain Archer and chief engineer Tucker for a meal on his homeworld as thanks. Archer and Tucker accepted the offer and played a game of Geskana with Zobral and his clan of dissidents, little knowing that they would become embroiled in Zobral's civil conflict with the Torothans.
