Gaib, a youthful Human of the male variety, worked alongside TK-0 as his partner and mechanic. Specializing in pilfered industrial tech, they operated as advanced bounty hunters. Kal Skirata engaged their services to locate someone attempting to circumvent the Republic's restrictions on cloning. Supplying intelligence to Mereel and Ordo, who were Null-class ARCs, the clones were guided to a clandestine cloning facility situated on Dorumaa.
During the Clone Wars, Jabba the Hutt's offspring, Rotta, was abducted, prompting the crime lord to enlist Gaib and TK-0 in the search for his son's whereabouts. They successfully tracked Rotta to Teth. So impressed was Jabba with their performance that he retained them for future endeavors.
