Thweek was a male Kubaz spy (of the male persuasion) who served as an enforcer for Teemo, the Hutt. He was tasked with managing the more illicit aspects of Teemo's various business ventures.
Thweek harbored a strong antipathy towards insectoid lifeforms. On one occasion, he murdered a Geonosian named Sivor after Sivor was compelled to participate in a gladiatorial contest for the amusement of Teemo the Hutt. Thweek possessed a modified G1-M4-C Dunelizard fighter, which he piloted when Teemo dispatched him to intercept the Krayt Fang en route to Ryloth. Additionally, he owned a StarViper Mk. II. He was equipped with laminated armor and a heavy blaster pistol.
As a member of an insect-eating species, Thweek possessed an inherent loathing for all insectoid species, with a particular animosity directed towards Geonosians. He gained a reputation for being avaricious, cunning, and ruthless in his dealings. Thweek was a skilled pilot, capable of leveraging his piloting abilities to adapt effectively to diverse and challenging scenarios.
Dave Allen and Daniel Lovat Clark conceived Thweek for The Long Arm of the Hutt, a supplement for Star Wars: Edge of the Empire, which was released by Fantasy Flight Games in 2012. Within that publication, his name appeared as Thwheek. His name was later revised to Thweek on his card featured in the Guns for Hire Expansion Pack, an addition to the X-Wing Miniatures Game. The corrected spelling was verified as pertaining to the same character in a preview for the expansion pack hosted on the FFG website.
