Competent and dangerous, this bounty hunter is ruthless and merciless to those he tracks or those who put themselves in his way. He is constantly alert and will draw his weapons if he feels as though someone is about to attack him. Endowed with a morality more than doubtful, it is difficult to make out his facial emotions because he never removes his helmet. Solitary and somewhat antisocial, the Mandalorian has a respectful relationship with the Mandalorian Armorer who is also aware of the fact that he is an orphan. He is also able to show great respect towards someone who earns his trust, like Kuiil, whom he even offered his gratitude when the Ugnaught had at the same time refused a payment and to become his partner. Aside from his loyalty to The Armorer, Mando submits to no other authority, whether it be the New Republic or the locals, as he claimed Cobb Vanth's armor without caring that he was a marshal. However, he is capable of making compromises, accepting deals that can achieve his objectives even if it takes more time. The Mandalorian deeply respects the creed of Mandalore, which act as the rules of the Tribe: he never removed his helmet in front of a living being even if his life depends on it and would prevent anyone from doing it. Beneath his stoic exterior, the Mandalorian is, in truth, a bit of a tortured soul who is plagued by the memories of his parents' death and the destruction of his village. 1.8-meter-tall (5'11") human male. While typically seen in scarred, rugged Beskar armor with a T-visored helmet, he has revealed a mustache and dark hair underneath. He wears a full suit of silver-and-brown beskar armor that appears battle-worn and scuffed. He is rarely seen without his helmet, which is a core part of his Mandalorian identity, though he has removed it in rare, critical moments.

Din Grogu, colloquially referred to as Baby Yoda or simply Grogu, is an infant member of the same species as the Star Wars characters Yoda and Yaddle, with whom he shares a strong ability in the Force. The protagonist known as "the Mandalorian" is hired to track down and capture Grogu for a remnant of the fallen Galactic Empire, but instead, he becomes his adoptive father and protects him from the Imperials. Later on he is given the name Din Grogu after being formally adopted by the Mandalorian, whose family name is "Din". Grogu is typically smaller than nearly everybody who comes by, mainly because he stands at about 16 inches when fully up.
