Religious Mandalorians like Din Djarin prove their devotion to the creed by never removing their helmets.
First, he removed his helmet to pass as an Imperial soldier to find Grogu's location. Then, when he found him, he removed his helmet so Grogu could say a proper goodbye before leaving to train with Luke Skywalker.
In episode 4, “Sanctuary,” the Mandalorian explained to Omera (the widow from the village he helped save) that Mandalorians can take off their helmets! Just, you know, not in front of other people. That's how the Mandalorian eats, as evidenced right after this conversation, where he takes off his helmet to eat alone.
For practical purposes - such as washing, eating, and (apparently) maintaining a well-groomed mustache, Mando is allowed to remove his helmet when he's alone. This was seen in The Mandalorian season 1 episode "Sanctuary," when Din took off his helmet to eat a meal that had been given to him by Omera.
The Armorer then asked Djarin if his helmet was ever removed at some point, to which he denied. Thus, she reminded everyone that their way of life was obeyed.
Yes, Mandalorians can marry, and in fact, they cherish family and shower affection upon those they love and care for. And in Mandalorian society, weddings typically happen immediately after a Mandalorian turns sixteen years old. They even have their own way of doing weddings.
The Mandalorian's Helmet and His Religion
“No living thing has seen me without my helmet since I swore the creed.” Cara Dune asks if he'll be killed for taking the helmet off, but Djarin says no, it's just that he can never put it back on again.
Din Djarin Is Force-Sensitive
But Mandalorians are trained to have Jedi-like reflexes to be able to overpower them, some of their armor and weapons even mimic Jedi abilities, like their sonic repulsors that knock objects away like a Force push.
George Lucas's Dream of a Star Wars TV Show
That's because this series has established a rule unknown in any previous Star Wars property: Mandalorians cannot remove their helmets in front of any other person. If they do, they are no longer considered a Mandalorian.
Mandalorians are not one particular race of species, and their religion is a way of life all may join if they are willing to follow the code, so the point of the helmet is to signify that they are in fact Mandalorian and not what the appear as underneath the helmet.
Every since the series debuted and confirmed that Mandalorians never remove their helmets, I've been wondering how they get any sort of nutrition. The answer, it turns out, is neither “through a secret hole somewhere” or “they exist on a liquid diet” but rather…they just eat in private.
But those who do observe that tradition can't take off their armor in front of another living thing. IG-11 took advantage of the droid-sized loophole to treat Mando's injuries. And when he did that, Din was fairly well-groomed underneath his helmet. So Mandalorians shower and shave, they just don't do it communally.
Various expanded universe reference materials tell us that Beskar originates from iron ore mined on Mandalore and its moon Concordia. Carbon is then added to it in the foundry to enhance its strength.
The Razor Crest was destroyed by a single shot fired by Gideon's light cruiser during a skirmish on Tython.
But in chapter 15, “The Believer,” Din Djarin, known to his friends (and us) as Mando, breaks that rule twice, first by donning the uniform of an Imperial cargo transporter and second by lifting off his helmet to show us the rugged face of one Pedro Pascal, the voice of Mando and the face of Mando, if not always the ...
"Boba Fett is a clone, according to Attack of the Clones, and by asking George Lucas, he would say Boba Fett is not Mandalorian, not born on Mandalore," said director Dave Filoni to Entertainment Weekly. "He's more of a person indoctrinated into it, into the way of life, and gets a hold of the armor."
While most of them are humans, there are also Mandalorians of various other species. Mandalore serves as the Mandalorians' home planet. It was originally inhabited by the Taung species, who renamed themselves Mandalorian and created the culture practiced by later non-Taung Mandalorians.
The Great Purge of Mandalore, also referred to as the Siege of Mandalore by Moff Gideon, was the genocide of the Mandalorians by the Galactic Empire after it bombarded Mandalore during the Imperial Era, the slaughter of most of the Mandalore population and the collection of beskar.
Grogu appears to be the youngest known member of Yoda's species. He is only 50 years old, and he is still developmentally an infant. For the whole first season of The Mandalorian™, they referred to him only as the Child. It seems that the species is, for whatever reason, quite slow to age.
In an unexpected twist, Mando hit up The Book of Boba Fett and got himself a new ship. And yes, Mando's smooth new ride is the same kind of starfighter flown by young Anakin Skywalker in The Phantom Menace. Here's the history of it, why it was such a big deal in 1999, and why it's perfect that it's back.
In Mandalorian vs Boba Fett, Din Djarin's character is the winner. While both of them share similarities and differences, Mando's capabilities get the upper hand. The similarities with the line of work, armors used, and origin contributes to the close fight between the two.
Over 20,000. Even Master Yoda doesn't have a Midi-Chlorian count that high.”
Aside from looking cool, Mandalorian armor had both a practical and cultural significance to its wearer. Mandalorian armor was generally made with beskar, a durable alloy capable of deflecting blaster bolts and withstanding lightsabers.
The rifle was aboard the Razor Crest on Tython while Djarin took Grogu to an ancient stone temple of the Jedi. During a subsequent encounter with Moff Gideon's remnant Imperial forces, Gideon shot Djarin's ship with an orbital laser blast from his light cruiser, destroying the ship and the rifle.
In other words: Boba Fett's entire body is basically scar tissue. So it makes sense he'd spend a lot of time in the Bacta Tank. But beyond simply healing his body, it's possible Fett is also using his bathtime to heal his mind too.
