Gust Toruna, alternatively called Guster, was a male Twi'lek who existed in the final years of the Galactic Republic.
In the era of the Clone Wars, Toruna was employed by the criminal figure Vex, operating on the planet of Cularin. Toruna was among a team of couriers dispatched by Vex to move an illegal consignment. However, they encountered an assault from a gang of hoodlums in the service of Riboga the Hutt, resulting in the demise of all the couriers. Toruna managed to evade death, being substituted by a timeshadow duplicate of himself.
When Vex eventually located Toruna, he was enraged by the loss of the shipment and instructed his Trandoshan muscle, Raptor, to assault the Twi'lek. Toruna recounted the events, and Vex professed to accept Toruna's story of his supposed death. Nevertheless, to verify the veracity of Toruna's account, Vex ordered Raptor to shoot Toruna. A timeshadow did not appear this time, and the shot proved fatal for the unlucky Twi'lek.
