The Culisetto male Doctor Cribiriz Idollax was a warlord and droid mechanic who held a on an unidentified planet serving as his headquarters. He had a brother named Sribiriz, who was known to be good-hearted and selfless. Sribiriz was strongly against his brother's criminal and violent activities, despite loving him.
Idollax crafted his own droids that served him as guards and henchmen.
One day, before 9 BBY, Sribiriz told his brother he was going to report his crimes to the authorities. Therefore, Cribiriz decided to change his ways and to stop being a criminal. On that same day, Deva Lompop hired a group of bounty hunters, including the infamous Zuckuss and 4-LOM, to kill the Culisetto warlord, who, in her opinion, was becoming a threat. After breaking into Idollax's facility, Zuckuss and 4-LOM found Sribiriz and, mistaking him for his brother, shot him, killing him, while Cribiriz, hidden, watched. Doctor Idollax then swore revenge against the murderers of his brother and went into hiding from the rest of the galaxy.
While hiding, Idollax tried to learn more about the bounty-hunter duo, and he came into contact with the deserter Imperial stormtrooper Sardis Ramsin, who, in 3 ABY, brought him 4-LOM's severed head, which had been found by the Jawas on Tatooine, after it was separated from the original body by the bounty hunter Boba Fett. Idollax then created a new giant spider-like droid, reprogramming 4-LOM's head, and sent it to pursue Zuckuss.
On Nar Shaddaa, Zuckuss fought his ex-partner along with other bounty hunters, and won. During the battle, the Gand findsman discovered the presence of his old enemy, Doctor Idollax, who explained his story and plan. Zuckuss, after the Culisetto mechanic finished talking, shot him with his rifle, killing him.
