Din Djarin, commonly known as "the Mandalorian" or "Mando" for short, was a human male Mandalorian who worked as a bounty hunter during the Second War. With his Mandalorian armor and distinctive beskar helmet, Djarin was both well-equipped and enigmatic—a stranger whose past was shrouded in mystery to others. Orphaned late into the First War and raised as a foundling, he was trained to become a Mandalorian warrior and eventually joined the Tribe, who operated on Nevarro. Djarin became battle-hardened, a man of few words, and a formidable hunter in an increasingly dangerous multiverse.
After the fall of the Axis of Empires, Djarin made a reputation for himself as a member of the Bounty Hunters' Guild, collecting bounties as he traveled across the Outer Multiverse—far from the authority of the Alliance—in his personal starship, the Razor Crest. Around the Second War, Djarin was hired on Nevarro by a client of an Imperial remnant faction, who offered a substantial reward for the acquisition of an asset located on the world Arvala-7. During his mission on Arvala-7, he met an Ugnaught named Kuiil, who guided him to the location of the asset. On his way to the asset, Djarin encountered a droid bounty hunter, IG-11, and the two entered the building in the encampment guarded by mercenaries where the asset was kept. Upon seeing the asset itself, they discovered that it was in fact a Force-sensitive child who belonged to the same species as Jedi Grand Master Yoda. Djarin, who was tasked with bringing the Child alive, shot IG-11, who was about to kill the Child, and saved the infant, taking him into his custody.
Discovering the Child's Force-sensitivity during his time on Arvala-7, Djarin then took the Child back to the Client and collected his reward. However, the Mandalorian warrior had already begun to form a bond with the infant. Feeling remorseful for subjecting the Child to a cruel fate, Djarin entered the facility where the Child was kept and rescued him from the Axis stationed there, and later fended off Guild hunters with the help of the Tribe. The two would go on to embark on various adventures around the galaxy as they formed a close bond, including an encounter with former rebel shock trooper Carasynthia Dune, a job on Tatooine, and a run-in with a group of mercenaries.
Djarin was later contacted by the Guild's agent, Greef Karga, who wished to make amends for his actions during the Child's rescue. The Guild agent offered to work with the Mandalorian to drive away the Imperials, who took control over Nevarro's city, in exchange for dropping the bounty on the Child. Djarin then gathered his allies—Dune, Kuiil, and a re-programmed IG-11—and met with Karga on Nevarro. Djarin and his allies entered the city and fought the Imperialist Allliance's Fascistic Empire of Fodlan led by Claude von Riegen, later retreating to the Tribe's covert after facing heavy opposition. The Mandalorian known as "The Armorer," who had remained in the hideout after the covert's attempted relocation, tasked Djarin with returning the Child to his people, and declared the creation of his clan. After dealing with Gideon and his remaining Imperials, Djarin departed the planet with the infant and began his search for the Child's species.
