Vusk was a pirate of the Warbird gang, a male Kassk. His physical characteristics included yellow skin and green eyes. He was clad in white scout trooper armor distinguished by red markings.
The character Vusk was initially credited in "A Quick Salvage Run," with Jason Hightower providing the voice. In the initial versions of "Kaz's Curse," Vusk was intended to be the pirate responsible for cursing Kazuda Xiono, but this was later altered to the Nikto named Leoz.
