During the era of the Galactic Republic, a Trandoshan held the position of leader within a criminal organization. Around 32 BBY, these Trandoshan criminals attended the auction of Eldra Kaitis, a Jedi Padawan, which was orchestrated by the crime boss Xev Xrexus. Darth Maul, a Sith apprentice, dispatched a group of bounty hunters to seize Kaitis from the auction's winner. However, as they attempted their escape, their vessel suffered sabotage, leading to a crash landing on the moon of Drazkel.
Xrexus then presented the attendees who had been unsuccessful with an opportunity to hunt down Kaitis and those who were supposedly liberating her, and the Trandoshans were among those who touched down on the moon to pursue this offer. While in pursuit of Kaitis, the Trandoshans encountered Cad Bane, a bounty hunter working with Maul. The leader agreed to Bane's proposition of a duel, but instead, the bounty hunter and his associates proceeded to kill the Trandoshans.
During the time of the Galactic Republic, the Trandoshan served as the head of a Trandoshan criminal group. In 32 BBY, not long before the Invasion of Naboo, the Trandoshans received an invitation to the space station hideout of Xev Xrexus, the crime boss leading the Xrexus Cartel. Xrexus was organizing an auction for the Jedi Padawan named Eldra Kaitis. As the guests awaited the event's commencement, a group of bounty hunters commanded by Cad Bane and in the service of the Sith apprentice Darth Maul, who had infiltrated the auction disguised as members of the Haddrex Gang, walked past the Trandoshan group. The Trandoshan leader mocked FE-B3, a former Haddrex protocol droid whom Bane's group had tortured to guide them to the auction, specifically pointing out the droid's deficiency of photoreceptors. Bane responded by threatening the Trandoshan to refrain from interfering, leaving the Trandoshan in a state of shock.
Xrexus soon appeared to greet the attendees, and the auction commenced two hours thereafter. In the end, the industrialist Jee Kra emerged as the victor, intending to depart immediately with Kaitis. However, Maul's group launched an ambush on him at his starship, successfully capturing Kaitis. Xrexus had anticipated this outcome, and thus, he disabled the stolen vessel, causing it to plummet toward the moon of Drazkel below.
With the occupants of the wrecked starship still alive, Xrexus addressed the remaining attendees, offering them the opportunity to pay for the privilege of landing on the moon and hunt down the survivors. The Trandoshans, along with other criminal groups, descended to the moon and initiated a hunt for Kaitis and those who had captured her. Maul took Kaitis, leading the hunters away from their vessels so that his accomplices could steal one.
While navigating the moon's rugged terrain, the Trandoshan leader noticed indications of recent passage, leading him to believe that their group was closing in on Kaitis. However, they were instead confronted by Bane, who challenged the Trandoshan to a confrontation. The Trandoshan accepted Bane's challenge, instructing the group to lower their weapons and allow Bane to live if he emerged victorious. Despite the leader's overconfidence, the anticipated showdown never transpired—the Trandoshan was ambushed from above by the bounty hunter Vorhdeilo, while Bane and his associate Aurra Sing fatally shot the remaining criminals dead.
The leader was a Trandoshan characterized by orange eyes and green skin. The Trandoshan was confident that Bane would not survive their proposed duel, yet instructed the other Trandoshans to act fairly and permit the bounty hunter to live should he prevail. While present on the Xrexus Cartel space station, the Trandoshan mocked the protocol droid FE-B3 for lacking eyes.
The Trandoshan was dressed in a black shirt, short gray pants, and an orange vest, complemented by metal bands on both left limbs. The criminal was armed with a blaster rifle and carried an additional blaster in a holster. The group utilized a HCT-2001 Dragonboat-class Reugeot 905 to journey to the auction of Eldra Kaitis and subsequently landed the freighter on the moon of Drazkel to pursue the Padawan.
The Trandoshan made his initial appearance in the second issue of the comic series titled Star Wars: Darth Maul, penned by Cullen Bunn, illustrated by Luke Ross, and released by Marvel Comics on March 22, 2017.
