Cobb Vanth, also known as «the Marshal,» was a human male who lived during the Galactic Civil War and subsequent New Republic Era. Once a slave, he rose to become marshal of Mos Pelgo on the planet Tatooine. He despised the Red Key Raiders, a syndicate attempting to establish itself on the planet. Immediately following the Battle of Endor, Vanth fled into the desert following Mos Pelgo’s takeover by the Mining Collective. He then encountered some Jawas and traded a camtono of silicax oxalate crystals for a set of Mandalorian armor.
Just then, Red Key employee Adwin Charu approached the sandcrawler. Vanth conversed with Charu and helped the man find valuable equipment on the vehicle. When Charu found the armor and wished to take it for himself, Vanth injured Charu, leaving him alive to send a message to his boss Lorgan Movellan. Vanth returned to town and single-handedly drove away the Collective, assuming the role of mayor and protector of Mos Pelgo.
As sheriff and mayor of Mos Pelgo, which was eventually renamed Freetown, Vanth led the residents in defying the Red Key Raiders. In 5 ABY, he rescued the beastmaster Malakili from a pair of raiders. Vanth recruited the beastmaster to tend to some rontos in Freetown and an infant Hutt which had been acquired from the Red Key Raiders.
Sometime later, the Red Key attacked and captured Freetown, overpowering the residents. Movellan confronted Vanth, both questioning each other’s motives on Tatooine. The Hutt was then brought out with Malakili, and it gave a shriek, signaling Tusken Raider reinforcements against the Red Key Raiders. Vanth then carved a message onto Movellan for the crime boss’s superiors.
By 9 ABY, Vanth still led and defended the town, including battling Tusken Raiders who raided their village multiple times. At one point, the Mandalorian bounty hunter Din Djarin came to town searching for a fellow Mandalorian. Vanth agreed to give Djarin his armor in exchange for helping him kill a krayt dragon that lived nearby. Vanth and Djarin allied themselves with a local group of Tusken Raiders as well as the people of Mos Pelgo and succeeded in defeating the beast, after which Vanth gave Djarin the armor and parted ways with him.
Later, when the Pyke Syndicate was attempting to absorb Tatooine into their spice trade, Vanth killed three Pykes who were trying to smuggle spice in his territory. A single survivor was allowed to escape in his landspeeder. Shortly following this, Vanth was shot by Cad Bane, who told the inhabitants of Freetown that if the spice trade continued, they would remain unharmed.
