Around 9 ABY on the ice planet of Pagodon, the Alpha Trawler, a human, menaced a Mythrol inside a public house. He was accompanied by another human and a Quarren. Speaking in Huttese, he threatened to sell the Mythrol's glands at the spaceport, remarking on the sweetness of his musk due to his young age. During this confrontation, Din Djarin, a Mandalorian bounty hunter, arrived to collect a bounty on the Mythrol. The Alpha Trawler, along with his two associates, confronted Djarin, alleging that the bounty hunter had caused him to spill his beverage. A brawl then erupted, ending with Djarin subduing all three of them.

Working as a trawler on the frozen world of Pagodon circa 9 ABY, this human male engaged in the harassment of a young Mythrol within a public house located in Ferryman's Reach. He was joined by a Quarren and a fellow human. Speaking in Huttese, the trawler suggested selling the Mythrol's glands at a nearby port, commenting that the musk he produced would be quite sweet. Despite the Mythrol placing his credits on the table as an offering, the human prepared to attack him with a knife, while the Quarren pulled him to his feet.
The arrival of Din Djarin, the Mandalorian bounty hunter, interrupted their plans before they could harm the Mythrol. Noticing the spilled drink on the table, the human claimed that the Mandalorian had caused the spill as he approached the counter, thus signaling his companions.

As he continued to threaten Djarin, the bartender translated his words into Basic. The human then inquired if the [armor](/article/armor] Djarin wore was truly made of beskar, as the other trawlers moved to surround him. As the bartender slid another drink towards the human, Djarin seized the cup, threw the contents back in their faces, and then smashed the cup into the other human trawler, rendering him unconscious.
Subsequently, he slammed the Quarren's face against the counter. The Alpha Trawler then attempted to stab Djarin with his knife. However, Djarin seized his arm and redirected the blade, causing it to stab the Alpha Trawler in the back, thus incapacitating him. Djarin then used his whipcord launcher to ensnare the fleeing Quarren and fired it at the entrance controls, activating the door and bisecting the Quarren.
This human possessed fair skin marked by a scar on the right side of his face. He was bald, sported a dark brown beard, and was fluent in Huttese. He disregarded the Mythrol's offer of credits, as he deemed the Mythrol's glands to be a more lucrative prospect. Upon noticing Djarin, he exploited the spilled drink as justification to threaten him.
The human was armed with a knife and wore a brown coat, brown trousers, and black gloves.
