Stallo was a human individual who made their home on the planet of Carajam between the years of 2 BBY and 4 ABY. This person engaged in conflict with the criminal organization known as the Xan sisters, which resulted in a bounty being placed on their head, using the pseudonym "Tal Joben." The bounty hunter Boba Fett once collected a bounty on the criminal Zingo Gabnit, which unintentionally saved the village where Stallo's sister resided. Consequently, Stallo requested assistance from Fett to fight against the Xan sisters, but the hunter identified Stallo as Tal Joben and threatened them with a blaster.
Stallo was a human who resided on the planet Carajam, located within the Outer Rim Territories. They undertook the task of confronting the Xan sisters and their criminal network, who were causing problems for local farms, even killing two of the sisters. The Bounty Hunters' Guild had issued a bounty for Stallo, either dead or alive, under the alias Tal Joben. Stallo had a sister who lived in a village on Carajam. Between 2 BBY and 4 ABY, Zingo Gabnit, an associate of the Xan sisters attempting to trap the bounty hunter Boba Fett, held the village hostage. In the end, Fett liberated the villagers and eliminated Gabnit, taking his corpse to a town to claim his reward. News of Fett's actions had already spread through the town, so Stallo quickly recognized the bounty hunter and thanked him for saving their sister's life, prompting others in the crowd to do the same.

To Stallo's bewilderment, Fett silently proceeded to drag Gabnit's body into a cantina. As the body was handed over to an agent from the Bounty Hunters' Guild, Stallo followed Fett and inquired if he would assist them in their fight against the Xan sisters. Stallo explained their actions, including the deaths of two of the sisters, but Fett continued to ignore them. The Guild agent cautioned Stallo that the Xan sisters had allies within the Galactic Empire and that they could face serious consequences if they persisted in their pursuit. Stallo pleaded with Fett for his help once more, believing him to be a hunter of evildoers. At that moment, Fett spotted a hologram advertising the bounty on Stallo, and he declared that he only hunted for bounties as he aimed his blaster at Stallo.
Stallo's motivation for fighting the Xan sisters stemmed from their terrorizing of farms on Carajam. Recognizing their limitations, they sought assistance from Boba Fett, mistakenly assuming that Fett shared their moral principles. Even after being warned about the Xan sisters' connections to the Empire, they continued to ask for Fett's help. Stallo had a complexion of tan skin, gray eyes, and graying hair accompanied by a black goatee. A prominent scar stretched across the right side of their face.
Stallo made an appearance in the one-shot comic Age of Rebellion - Boba Fett 1, which was part of the Age of Rebellion miniseries. Greg Pak wrote the issue, Marc Laming provided the illustrations, and Marvel Comics published it on May 8, 2019.
