Rokko, a crime lord of the Hutt species, conducted illicit operations on the planet Coruscant during the era of 19 BBY. Affiliated with the Besadii clan, his criminal activities primarily centered around the Yaam Sector, where he was known for trading in stolen goods. During this period, his path crossed with that of Jax Pavan, a Jedi fugitive. Initially, Rokko enlisted Pavan's services to locate a Cerean named Toh Revo Chryyx. However, Chryyx took his own life while Pavan was trying to capture him, leading Rokko to refuse payment. When Pavan used the Force to protect himself from Rokko's bodyguards, the Hutt informed the sector police about the fugitive's presence. Nevertheless, Pavan successfully overcame the stormtroopers dispatched to apprehend him.
Later, Pavan sought Rokko's assistance in finding the droid 10-4TO, believed to possess crucial information for Whiplash, a clandestine resistance group opposing the Empire. Rokko agreed to help Pavan, motivated by the prospect of a substantial reward. However, the arrival of a Sullustan named Den Dhur at Rokko's residence, accompanied by a droid named I-5YQ who recognized Pavan, aroused Rokko's suspicion that Pavan's request was a scheme to assassinate him. Although he instructed his bodyguards to attack the group, he was compelled to quickly order them to cease their assault after I-5 threatened to destroy his prized possessions, decelerated luminescent images, which were rare depictions of Nal Hutta. Consequently, Pavan and his companions managed to escape from the Hutt.
Rokko's birth occurred around 400 BBY on Nal Hutta, as a member of the Besadii clan. At some point, Rokko relocated to Coruscant, the capital world, where he established a modest criminal enterprise within the Yaam Sector of Galactic City. The crime lord primarily engaged in the trade of stolen goods, accumulating a significant fortune and establishing a reputation for himself on Coruscant.
In 19 BBY, Rokko contracted Jax Pavan, the Jedi fugitive who was earning a living as a bounty hunter, to track down a Cerean named Toh Revo Chryyx, promising Pavan 15,000 credits for Chryyx's capture. However, Chryyx committed suicide by stopping his heart after Pavan apprehended him. Given that the bounty stipulated that Chryyx be delivered alive, Rokko went back on his promise. Pavan met with Rokko and two of his bodyguards in the Blackpit Slums area of the underlevels, where Pavan demanded payment, arguing that he was not responsible for Chryyx's suicide. Rokko refused to pay the Human, asserting that the bounty specified Chryyx's acceptance only if alive.
When the Human reiterated his demand for payment, Rokko ordered his two bodyguards—a Nikto and a Klatooinian—to attack Pavan. However, Pavan employed the Force to disarm the two, revealing his identity as a Jedi. Now aware of this, Rokko contacted the local Imperial sector police following the confrontation, hoping to claim the bounty on Pavan. Pavan defeated the stormtroopers sent to arrest him, and he suspected Rokko had dispatched them.
However, a few days later, Pavan arrived at Rokko's residence, seeking to speak with the Hutt. Rokko instructed his Aegis-7 battle droid to admit Pavan and his companion Laranth Tarak, a female Twi'lek. Pavan pledged to overlook Rokko's betrayal to the Empire if the Hutt would aid them in locating the droid 10-4TO. The protocol droid was rumored to possess information valuable to Whiplash, a clandestine resistance group. Pavan attempted to persuade Rokko that the Empire would be willing to offer a substantial reward for it, although the Jedi secretly intended to provide the droid to Whiplash.
Although the Hutt considered turning Pavan in for the bounty on his head, he decided against it and agreed to consider helping the two. While he was mulling over the idea, a Sullustan by the name of Den Dhur arrived at Rokko's home. Dhur claimed to have a droid that was an expert at the card game sabacc. Intrigued, Rokko allowed Dhur and the droid, I-5YQ, to enter. After playing the droid, the Hutt was stunned to find that it was able to beat him. He offered to pay Dhur 500 credits for it, realizing that it would be able to win many games against unsuspecting opponents, making money for the Hutt. After bargaining, the two settled on 1,000 credits.
Before Dhur left, Rokko asked the droid to fetch Pavan and Laranth. Unknown to the Hutt was that Dhur was not planning on selling I-5; rather, it was a ruse so that the two could find information about Jax Pavan, the son of I-5's late master. In his dying breath, Lorn Pavan had requested that I-5—whose intelligence bordered on sentience—help take care of his son should a need arise. Dhur and I-5 hoped that Rokko would be able to aid them using his intelligence sources, and so used sabacc as a front. When I-5 encountered Pavan in Rokko's house, he immediately informed the Jedi that he had been looking for him, per a request from Pavan's father.
Surprised to hear that a droid was going to tell him about his father and how Lorn Pavan had died, Pavan marched away to Rokko's throne room. However, after the Hutt realized that the droid knew Pavan, he assumed that it was not mere coincidence—rather, he thought, it was a plot to kill him. He had his bodyguards move to attack them but was quickly forced to call them off. I-5 had activated his finger-laser and threatened to destroy Rokko's most prized possession—his collection of decelerated luminescent images, works of the Hutt artist Gorgo. These were images frozen in time, as they were made of protium gas exposed to Nal Hutta centuries ago. These were so thick it took light years to shine through, making them essentially "windows to the past". As Gorgo had died centuries ago, the images were extremely rare; in fact, Rokko owned the only such images in the galaxy.
Due to his prized possessions being threatened, the Hutt immediately called off his bodyguards and allowed the group to leave. However, as soon as they had reached the turbolift, Rokko sent his Aegis-7 battle droid after them. The group was able to bring the ceiling down on the droid and escaped.
Rokko the Hutt possessed a greedy and ruthless nature, displaying minimal concern for others. Jax Pavan once remarked that Rokko would betray his own mother for financial gain, regardless of the amount. Rokko attempted to hand Pavan over to the Empire solely for the sake of a bounty, even though it was of little value. After Pavan later approached him, having survived the Empire's attempt to arrest him, Rokko agreed to collaborate with him, as the Human had a business proposition in mind. Although Rokko contemplated betraying Pavan once more, he concluded that the effort was not worthwhile. Jax Pavan also characterized Rokko as cruel and merciless.
However, Rokko also possessed a more sensitive side. He had a passion for art, particularly the creations of the Hutt artist Gorgo, and would go to considerable lengths, even allowing his enemies to escape, to safeguard them. Rokko held Gorgo in high esteem and expressed genuine sorrow that his works were nearing extinction.
Rokko was conceived by author Michael Reaves and made his debut in the 2008 novel Coruscant Nights I: Jedi Twilight, the inaugural installment of the Star Wars: Coruscant Nights trilogy.
