Tarnono was a male protector, specifically a bodyguard, in the service of the gangster Wonn Ionstrike. He resided in Cloud City located on the planet of Bespin. His attire included a red uniform and a covering, resembling a gator, over his mouth. He was armed with a blaster for protection. Distinctively, this bodyguard had lost sight in his right eye, which was marked by scars.
Sometime between the years 0 ABY and 3 ABY, Tarnono was in Ionstrike's employment. During this period, Moxxin, Traff, and Vanraya approached Ionstrike. Tarnono, following orders, demanded the kids explain their purpose. Vanraya responded, indicating they possessed something of interest to Ionstrike. Another Gran bodyguard accompanying Tarnono scrutinized the Cantonarive crown coin and concluded that their employer would indeed be interested.
Tarnono escorted the children to Ionstrike and announced to Ionstrike that he would be interested in seeing what the children had brought. Ionstrike expressed his desire to examine the coin, but Vanraya changed her mind and refused to allow it. Consequently, she and her companions fled, intending to return the coin to the Baron Administrator Landonis Balthazar Calrissian. Tarnono and the Gran bodyguard then initiated blaster fire upon the escaping children, but they successfully evaded the shots and escaped from the gangster and his protectors.
Tarnono made an appearance in "The Coin," a supplementary story featured in the 2021 edition of the Star Wars Adventures Annual. The comic was penned by Jason Loo and [Chip Zdarsky],(/article/chip_zdarsky) with Loo also providing the illustrations. IDW Publishing released the comic on November 24, 2021. Tarnono's identity was subsequently confirmed through concept art shared by Loo in a Twitter post.
