The Armorer, a Mandalorian Armorer of Mandalore, was a human female who guided [the Tribe](/article/the_tribe], a faction within the Children of the Watch, during the New Republic Era. After the Galactic Empire's [Great Purge of Mandalore](/article/great_purge_of_mandalore], she and the Tribe found refuge in a covert on the planet Nevarro, where she crafted armor and weapons for her fellow warriors. Circa 9 ABY, she used beskar provided by Din Djarin, the Mandalorian bounty hunter, to forge him a new suit of armor. During this time, she intervened in a dispute between Djarin and another member of the Tribe, Paz Vizsla, reminding them of their adherence to the way of life.
Following an attack by the Empire on their covert, the Armorer dedicated herself to recovering any salvageable beskar from the fallen Mandalorians. Upon encountering Djarin and his allies, she resupplied him, declared the formation of his clan after creating his signet, tasked him with reuniting Grogu with his own kind, and remained behind to gather the beskar and cover their escape. Subsequently, she evacuated to Glavis Ringworld, establishing a new covert with Vizsla.
Later, Djarin joined the Armorer and Vizsla, aiding them in rebuilding their covert. After confirming that Djarin had fulfilled his mission, she transformed his beskar spear into armor for Grogu. She then recounted the history of the Darksaber and the Night of a Thousand Tears, which their sect had survived due to their seclusion on the moon of Concordia. She instructed Djarin in the use of the Darksaber until Vizsla interrupted them, challenging Djarin to a duel, which Djarin ultimately won. Preventing Djarin from killing Vizsla, the Armorer inquired whether they had removed their helmets. Djarin admitted to doing so, leading the Armorer to declare him no longer a Mandalorian, unless he sought redemption in the Living Waters beneath the Mines of Mandalore.

The Armorer, originating from the planet Mandalore, belonged to the Children of the Watch, a Mandalorian faction devoted to the Way of the Mandalore. This group was regarded as religious extremists who had broken away from Mandalorian society, a separation initiated by Bo-Katan Kryze. During the [Imperial Era](/article/imperial_era], the Galactic Empire executed the Great Purge of Mandalore, unleashing heavy bombardment on the planet's surface and slaughtering millions of Mandalorians in what became known as the Night of a Thousand Tears. The Armorer and other adherents of the ancient ways had been stationed on Mandalore's moon of Concordia, thus surviving the devastation of the Night. Subsequently, the surviving Mandalorians were dispersed throughout the galaxy, concealing themselves in Mandalorian coverts to safeguard their numbers.
In the New Republic Era, she served as both a Mandalorian Armorer and the leader of [the Tribe](/article/the_tribe], residing within a covert located on the planet Nevarro. Her crafting of beskar armor in the age-old Mandalorian tradition was crucial in preserving her people's culture after the mass slaughter during the purge. She offered guidance to many Mandalorians, identifying their signets and replenishing their supplies. Around 9 ABY, Din Djarin, a Mandalorian bounty hunter, visited her, presenting an ingot of beskar he had obtained as a bounty. The Armorer recognized the steel as a product of the Great Purge and inquired whether his signet had been identified. Djarin replied that it had not, but she assured him it would soon be revealed. She then forged a pauldron from the beskar, setting aside the remaining metal for foundlings at Djarin's request.
After Djarin completed his bounty and received a camtono of beskar as his reward, he revisited the Armorer. She suggested crafting a full cuirass from the metal, which he accepted. As she examined the beskar, members of the Tribe gradually entered the armorer's quarters. She cautioned Djarin that the beskar would attract significant attention. Paz Vizsla, another member of the Tribe, remarked that the beskar was Imperial property and that the Great Purge had forced the Tribe into hiding. The Armorer countered by stating that surviving under such conditions was the source of their strength. Vizsla then mocked Djarin for conducting business with the Empire and attempted to shame him by removing his helmet, leading to a physical altercation between them.

She brought the fight to a halt by reminding them that the Empire was no more and that the beskar had been returned to its rightful owners. Addressing the Tribe, she described the Way of the Mandalore and how the bounty hunter had chosen his path. The Armorer then asked Djarin if his helmet had ever been removed. He denied it, and she reminded everyone that their way of life was to be obeyed. After easing the tension, the Armorer began questioning Djarin about the condition of his armor. He stated that it had been damaged by a mudhorn, but declined the signet because it had not been killed nobly. Instead of forging the signet, the armorer crafted whistling birds, explosive projectiles equipped on Mandalorian vambraces. She forged the armor and, again at his request, reserved some of the metal for the foundlings.
Some time later, Djarin and his companions Carasynthia Dune, Greef Karga, IG-11, and Grogu descended into the sewers in an attempt to escape Gideon's forces, who were looking to acquire Grogu. Din Djarin was distraught when they discovered a pile of Mandalorian helmets, and he angrily confronted Karga, believing that the Bounty Hunters' Guild had retaliated against the enclave for assisting Djarin's escape. To his surprise, the Armorer was still in the tunnels, collecting pieces of armor that had been abandoned by their owners or taken from the dead. She also defended Karga, explaining that the Imperials discovered the enclave shortly after Djarin's escape.

The Armorer assured Djarin that she hoped some of the enclave's members had escaped, but she declined his invitation to leave the planet with the group, stating that she intended to stay until she had reclaimed all of the available beskar. She also revealed her knowledge of other beings with Grogu's abilities, classifying them as enemies of the Mandalorians, but she considered this individual a foundling to be cared for. Recognizing Djarin's affection for Grogu, she bestowed a signet on him that designated him and Grogu as "a clan of two" and charged him with returning the infant to his own people. She also gave him a jetpack before they parted. Shortly after, a detachment of stormtroopers entered her chamber, only to find the Armorer kneeling before the forge, holding her hammer and tongs. She then proceeded to attack and kill all of them using only her tools.
At some point after the Clash on Nevarro, the Armorer had left the forge, and Aqualish thieves had taken over what remained of her workshop.
The Armorer managed to locate Paz Vizsla, and the two of them relocated to Glavis Ringworld. There, they began to rebuild the covert for their Tribe. They left signs leading to their new covert along Glavis Ringworld's Kolzoc Alley that were visible to vision settings in his macrobinocular viewplate. Djarin found them and joined them. The Armorer had Vizsla tend to his wounds, which were accidentally caused by his weapon, the Darksaber. Vizsla revealed that only the three of them remained from the Tribe after the remnant's attack.
The Armorer inquired what weapon caused Djarin's wound, and he revealed it was the Darksaber. The Armorer had Vizsla bring it to her. She examined the Darksaber, and told Djarin the history of it, and it's creator, the Jedi and Mand'alor Tarre Vizsla of House Vizsla. Djarin told her that he completed his quest, as Grogu had been returned to the Jedi. Seeing his quest complete, she welcomed him to the covert. While Djarin and Vizsla were setting up her forge, Vizsla asked Djarin how he had acquired the Darksaber, and the fellow Mandalorian confirmed he done so by defeating Moff Gideon, who had been involved in the Great Purge. When Djarin told him that he did not kill the moff, and that instead he had been sent to the New Republic to be questioned and to face justice, Vizsla declared that death would have been justice for Gideon, and the Armorer agreed as millions of Mandalorians had died because of the moff. She doubted that the New Republic Tribunal would execute him.
The Armorer told Djarin that songs of eons past foretold the mythosaur rising up to herald a new age of Mandalore, but it only existed in legends. She asked him how he acquired his [beskar spear](/article/beskar_spear], and said that the weapon's existence put Mandalorians at risk, because it could pierce beskar armor. She claimed that beskar was meant for armor and not for weapons. Djarin asked her to reforge it into an armor for Grogu. As she was melting the spear, Djarin asked her if she heard about Bo-Katan Kryze. The Armorer replied she was a cautionary tale, and told him how she tried to lead Mandalore through her bloodline and Darksaber, which was gifted to her and not won by Creed. The Armorer believed that those born of Mandalore lost their way, and Kryze's rule ended in tragedy when the Great Purge happened. She claimed it was a curse prophesized in the Creed, and only those that walked the Way were able to escape it, as during the Purge, their sect were cloistered on the moon of Concordia. She claimed that their adherence to the Way preserved the Mandalorian legacy for generations until they may someday return to their homeworld.

After she forged an armor for Grogu, she trained Djarin with the Darksaber. Djarin said that the blade was becoming heavier with each move, and the Armorer replied that it was because he was fighting against the blade, and that the Darksaber could not be controlled with strength. She said that his body was strong, but his mind was distracted. Seeing Djarin's unsuccessful attempts, Vizsla, who was a descendant of Tarre Vizsla, challenged Djarin to duel for the Darksaber, as he wanted to restore the blade back to his clan. The Armorer asked Djarin if he agreed to the duel, and Djarin accepted the challenge.
Eventually Djarin was able to defeat Vizsla, and held his vibro-knife around his challenger's throat, and the Armorer declared the duel over, with Djarin being the winner. She asked them if they removed their helmets, the same way she did when she previously halted their brawl in the covert on Nevarro. Vizsla replied that he did not, but Djarin admitted that he did, as he had to remove his helmet so he could rescue Grogu, and he also took his helmet off before Grogu departed with the Jedi Luke Skywalker.
The Armorer claimed that Djarin was no longer a Mandalorian. In reply, Djarin begged for her forgiveness and asked how he could atone. Vizsla called him an apostate, and wanted him to leave their covert. The Armorer replied that according to Creed, he could only be redeemed in the Living Waters beneath the Mines of Mandalore, which Djarin believed was destroyed. Djarin thus left and took the Darksaber with him.
The Armorer and Paz Vizsla would eventually depart the Glavis Ringworld and worked to restore the rank of the Children of the Watch with a new covert, which the Armorer led on an rocky desert planet. They recruited dozens of new Mandalorians to their cause, including those from the Clans of Eldar and Kryze. Additional survivors from the slaughter of the Armorer's initial covert also managed to locate and rejoin her on the planet.
During an initiation ceremony for Ragnar, the newest of their member to take the creed, the Armorer forged the child's first helmet and began to recite the Way of the Mandalore to name Ragnar a true member of the covert. Before she could complete the ritual, she sensed the presence of a lake monster and hastily pushed Ragnar to safety. In the ensuing battle, the Armorer rushed past the legs of the beast to retrieve a Mandalorian trapped beneath the waves, though she would soon be thrown aside by the creature as the other Mandalorians proved unable to defeat the beast. Before it could wreak further havoc upon the covert, the N-1 starfighter of Din Djarin arrived, which quickly slew the beast with a torpedo.

Meeting within her expansive workshop, the Armorer reminded Din, her former apprentice, of his past transgressions against the Mandalorian code and his resulting expulsion. She voiced her opinion that his hopes for absolution were likely unattainable, given the widespread belief that the Living Waters within Mandalore's Mines had been obliterated during the planet's Great Purge. In response to these assertions, he presented her with a fragment of inscribed glass, explaining that he had acquired it through trade with Jawas, who claimed to have obtained it from a traveler who had dared to venture to Mandalore. This fresh information, coupled with the glimmer of hope for the Living Waters' survival, led her to endorse his new endeavor and declare that his success would signify his redemption in the eyes of the covert.
Subsequently, Din made his way back to the covert, accompanied by the disgraced Bo-Katan of House Kryze, having successfully completed a mission to Mandalore and immersed himself in the Living Waters. He presented the Armorer with a vial of the water as proof, which she verified as originating from the ancestral mines by allowing a single drop to mingle and resonate with the forge's cooling water. The Armorer proclaimed Din no longer an apostate, welcoming him back into the covert's ranks. Moreover, she extended an invitation to Bo-Katan to join the covert, acknowledging that she too had bathed in the water and adhered to the Mandalorian code by consistently wearing her helmet, thus maintaining her legitimacy as a Mandalorian under the Way of the Mandalore.
Following the acceptance of Clan Mudhorn and Bo-Katan into the covert, the Armorer observed her people as they engaged in combat training. She stood silently beside Paz Vizsla, watching with interest as Grogu employed his Force abilities to overcome Paz's son Ragnar. Suddenly, a large reptavian shriek-hawk seized the human youngling and soared towards its nest, prompting several Mandalorians to give chase. Upon their return with intelligence gathered by Bo-Katan, who had tracked the creature in her Gauntlet starfighter, the Armorer assembled a hunting party, including Din, Bo-Katan, Paz Viszla, and the Shriek-hawk Training team, and watched them depart before she led Grogu into the cavern which contained her forge.
She initiated the forging of a rondel for the foundling, elucidating the significance of Beskar and the cultural importance of forging to the Mandalorians, emphasizing the need to secure a future for generations to come. Unbeknownst to her, as she hammered the steel, Grogu experienced a flashback to the night of Order 66 and his rescue by the Jedi Master Kelleran Beq. He snapped back to the present as she completed the chest plate and placed it over his chainmail.
The hunting party soon returned, having successfully slain the beast and returned Ragnar to the safety of the covert, along with the three orphaned chicks of the beast to be kept and domesticated. The Armorer commended Bo-Katan for taking leadership of the situation, and offered to forge her a new pauldron to replace the one she lost in the battle with the beast. Within, she inquired if Bo-Katan wished to inscribe the signet of the Nite Owls on her replacement, but accepted Bo-Katan's request for her signet to instead be of the mythosaur skull, which she noted was a symbol of all Mandalorians. Bo-Katan then revealed that during her quest with Din on Mandalore, she encountered a live mythosaur within the Living Waters. The Armorer chose to interpret it as a noble vision, but when Bo-Katan clarified her meaning, the Armorer doubted such a possibility, and only commented that one who walks the Way of the Mandalore will see many things, before leaving Bo-Katan alone, who contemplated the skull of the beast mounted upon the wall.
The tribe's isolation was soon disrupted by New Republic pilot Carson Teva, a former comrade of Din Djarin, who, utilizing information from ex-wingman R5-D4, managed to locate the covert. He informed Djarin of a distress signal from Greef Karga, the High Magistrate of Nevarro, whose city was under siege by a pirate horde commanded by Gorian Shard. Carson insisted he merely wanted to let Djarin know his friend was in danger before departing, promising to keep the covert a secret. Din arranged a meeting with the whole tribe, including the Armorer, to discuss the matter, seeing an opportunity for permanent relocation. He spoke to the other Mandalorian's of letting the foundlings and their futures be ensured as the beloved heroes of an independent world safe from the reach of the wider galaxy. Following a speech from Paz Viszla in his support, the Armorer declared that Din's path was the way and began to plan a counterattack against the pirates.
Several strike teams traveled to the planet on Bo-Katan's starfighter, the teams quickly dropped into the city with their jetpacks and engaged in combat with the hordes of pirates while Din fought off the fleet of pirate starfighters which defended Gorian Shard's Corsair. During the battle, a blaster cannon was set up by the pirates in Karga's office, which was able to pin down several Mandalorians fighting near the Statue of IG-11. The Armorer snuck into the office, and quickly dispatched the pirates with her hammer and tongs, which turned the tide of the battle on the ground in her people's favor. The Mandalorians proved victorious as Din and Bo-Katan managed to destroy Gorian Shard's Corsair and the final pirates were captured by the people of Nevarro and the Mandalorians.
After the battle, Karga expressed his gratitude and gifted his saviors a tract of land between the western lava flats and Bulloch Canyon, providing the Armorer's people with a home. She returned to her forge in the Nevarro sewer, having Paz lead Bo-Katan to her as well. She spoke of the Great Forge of Mandalore, and remarked on how despite their difference in quality, both forges served equally to their people, and ordered Bo-Katan to remove her helmet. The Armorer insisted despite Bo-Katan's hesitance, and explained how Bo-Katan had walked both the way of her covert and of their people's ways before the purge, and thus was the best suited to unite their people. She led Bo-Katan out to Din and the other shocked Mandalorians, and explained how Bo-Katan would depart them as an ally, to reunite other scattered Mandalorians with the intent of them all retaking their ancestral home of Mandalore.
The Armorer remained on Nevarro as Bo-Katan underwent a Mission to Plazir-15 to consolidate her former forces, and looked on from the Tribe's camp ground as the Mandalorian fleet of Bo-Katan's Mandalorian group arrived over the city. As the new faction docked and approached the Children of the Watch, the Armorer clashed her forging tools together and bid them welcome as fellow Mandalorians, and promptly declared a feast. Later that evening, she listened as Bo-Katan petitioned her people to join her on a scouting mission to Mandalore, with the Armorer being the last to declare their intent to join the expedition.
The following day, the group arrived on the planet and set out to establish a safe perimeter around the Great Forge within the ruins of Sundari. During their travels, the group were approached by Mandalorian survivors from the Great Purge who redeclared their loyalty to Bo-Katan and offered to bring the group to the Forge. During their travels, the captain of the survivors questioned how the Armorer's people survived the Purge, to which she explained the Children of the Watch were sequestered on the moon of Concordia. He further inquired if they were affiliated with Death Watch, to which the Armorer simply stated Death Watch was no more as Bo-Katan spoke of the division of her people.
As dawn broke the next day, the Armorer tended to the weakened and wounded of the Mandalorian survivors. She requested to bring the injured back to the waiting Mandalorian fleet before they reached Mandalore. Bo-Katan concurred with her request and the group divided. The Armorer departed to Bo-Katan's Gauntlet fighter and returned to the fleet, hailing the waiting Fleet Commander. Unbeknownst to her, Bo-Katan's group were ambushed and battled against Gideon and his forces.
Soon after, the Mandalorians above the planet were warned of the threat by Axe Woves, who demanded they flee the ship and provide support to the forces below. The Armorer donned a jetpack and departed on one of the ships toward the surface. She contacted Bo-Katan to inform her of the reinforcements and joined her side as the group's descended into Gideon's base by jetpack. They were confronted mid-flight by Imperial Commandos and engaged in aerial combat. The Armorer utilized her tools to bludgeon several commandos out of the air, and retreated to safety as Woves steered the Mandalorian forces' damaged Arquitens-class command cruiser into the base to destroy the Imperial base. The Mandalorians proved victorious as Gideon died in the ensuing detonation from the crash, though not without losses, as Paz Vizsla was killed in the early battle and the Darksaber was destroyed by Gideon's hand.

The Armorer traveled with the rest of the Mandalorians to the Living Waters, where she completed the initiation of Ragnar and welcomed him into the Children of the Watch. Din Djarin approached her at the steps to the water and asked if Grogu could be made an apprentice under him. She briefly refused, as he was too young to speak the Creed, but allowed Din to name him an apprentice as the child's adoptive parent, and rechristened him as Din Grogu. She implored Djarin to take Grogu on a journey as his own teacher once did for him, which he accepted. Soon after, she handed off a ceremonial torch to Bo-Katan to relight the Great Forge's long dead flame as her people looked on and chanted in victory.

Standing at 1.7 meters tall, this female Mandalorian projected an aura of wisdom, tranquility, and composure. Notably, she possessed a remarkable degree of diplomacy, especially considering her Mandalorian heritage. She skillfully diffused the escalating tension between Din Djarin and Paz Vizsla by reminding them of the Tribe's guiding principles, a necessity given the dwindling numbers of Mandalorians at that time.
Her dedication to the Way of Mandalore was absolute, as evidenced by her strict adherence to the prohibition against removing one's helmet. When Djarin confessed to having violated this sacred tenet, she declared him no longer a Mandalorian, effectively exiling him from their covert at a time when their numbers were critically low. She held firm beliefs in curses and prophecies, asserting that the Darksaber, if not acquired through combat, would bring misfortune to the Mandalorians. Furthermore, she attributed Mandalore's destruction to the abandonment of their traditional ways by those born on the planet, emphasizing that only those who remained true to the Way had escaped the prophesied doom.
She also believed that beskar belonged to Mandalorians, and was willing to fight for it, as she refused to abandon the large cache of armor pieces left behind by deceased or escaped members of the enclave until she had reclaimed what beskar she could. She considered weapons that were made from beskar as taboo, such as a beskar spear, saying that its existence put Mandalorians at risk. She had no will to wield the Darksaber and rule the Mandalorians, as she bested Djarin in combat when she trained him to wield it, but did not challenge him to duel for the lightsaber.

The Armorer skillfully manipulated molten beskar into various forms, crafting both armor and whistling birds. Beyond her forging expertise, she was a formidable melee combatant, capable of neutralizing entire squads of stormtroopers using only her gravity hammer and magnetic tongs. During Djarin's Darksaber training, she demonstrated her combat prowess by defeating him with her signature tools. She possessed extensive knowledge of Mandalorian traditions, including ancient songs, prophecies, and the Tribe's Creed. During the reconquest of Mandalore, she wore a jetpack and used her tools as blunt weapons.
The Armorer was also a knowledgeable figure, including in the fields of Mandalorian history and culture. She gave guidance to the Tribe, including identifying their signets and instructing them about the Way, and had the ability to lead induction ceremonies. Her knowledge was valued by Djarin, who went to her to learn about Clan Kryze, and Kryze herself, who spoke to her about the apparent return of the mythosaur.

The Armorer's distinctive Mandalorian armor featured a gold beskar helmet adorned with five small horns. The helmet's visor was smaller than those typically found on female Mandalorian helmets, with more rounded eyeholes replacing the conventional angular design. She wore a fur coat over a bronzium-finished cuirass, along with heat-resistant boots, protective gloves, a dark brown kilt, and dark green pants. Her arsenal included various tools, such as a cryo-furnace, gravity hammer, and magnetic tongs, which she used for both forging beskar armor pieces and engaging in combat. Her forge served as a vital resource, providing the Tribe with a wide range of items and weapons, including whistling birds and jetpacks.

The Armorer made her debut in the inaugural first episode of the 2019 Disney+ television series The Mandalorian, which premiered on November 12, 2019. The character was brought to life by Emily Swallow, with Lauren Mary Kim serving as her stunt double in The Mandalorian, while Michelle Lee assumed the role in The Book of Boba Fett episode "Chapter 5: Return of the Mandalorian." The character's initial unveiling occurred in a trailer released the day before the series' debut.
The Armorer's helmet and complete costume were conceived by concept artist Brian Matyas. The helmet's design incorporates elements reminiscent of traditional blacksmith helmets, balanced by the classic Mandalorian armor aesthetic first introduced in Star Wars: The Clone Wars, notably the barn owl-shaped eyes. A themed armor set inspired by the Armorer was introduced to the Cartel Market of the Star Wars Legends video game Star Wars: The Old Republic as part of Game Update 6.2, alongside decorations reflecting the Armorer's forge.
During her audition for the role, Swallow was only informed that her character was a "leader" described as "strong and zen, but with authority." The character's description simply stated that "she was the leader of a group of people in hiding and she was masked." The level of secrecy surrounding the project was so intense that Swallow only knew she was auditioning for something potentially related to Star Wars, and she remained unaware of the full scope of the project. Her background in theater and her prior experience with mask work at New York University proved to be valuable preparation. One of the audition scenes Swallow performed was similar to a scene in "Chapter 3: The Sin" where the Armorer intervened to quell a dispute within her covert. She also delivered the line "This is the Way" without any prior context. On December 12, 2018, StarWars.com officially announced Swallow's casting in the series.
After Swallow started doing research on Star Wars, she spoke with executive producers Dave Filoni and Jon Favreau about was important to tell the show's story. She drew inspiration from Deborah Chow, one of the series' directors, as she was the first woman to direct a live-action Star Wars story. Swallow loved that there was little information about the Armorer's personal life. She also loved how the Armorer is a warrior who deliberately chooses when to fight, is dedicated to her people, and serves as a teacher to Din Djarin. Swallow made sure she did not connect too much to the Armorer's backstory because it helped her portrayal of the Armorer. Filoni and Favreau did not give Swallow much information about the Armorer, but they gave the actress a lot of freedom with character decisions. She did not get to see the script for scenes that her character was not in. Swallow frequently spoke with with Favreau and Filoni about the Armorer and Djarin's relationship.
The Armorer's scenes were filmed concurrently with her introduction in the series. Her costume was created to convey the character's authority over the other Mandalorians. Swallow said that not showing her face saved her about 90 minutes when she arrived to set because she did not need to go to hair and makeup. Swallow also said that not showing her face meant she needed to play more attention to her body language, especially after she landed the role and was on set. For the first few episodes, Swallow and the crew worked on discovering what the language of movement was and what translated well, which she said was a lot of fun. She would often trip on things in her forge and run into other Mandalorian actors. Wearing a helmet was disorienting for Swallow and she had no peripheral vision. She was distracted by having to look down, which made it hard to make the Armorer seem confident and measured. The crew would ensure that there was nothing in Swallow's way when she moved.
During filming, Swallow recorded all of the dialogue using a microphone in her helmet. After filming, Swallow and the crew collaborated on automated dialogue replacement and discussed if lines needed to be changed, though not much ADR was necessary because the dialogue had already been recorded. She credits Favreau, the directors, and the editors for helping to make her performance seem effortlessly confident. She said that playing the Armorer feels liberating due to people loving and respecting the character not because of her appearance.

Swallow did not know if she would ever return to Star Wars. She later reprised her role as the Armorer in "Chapter 5: Return of the Mandalorian" of The Book of Boba Fett television series. Swallow spoke with Filoni and Favreau in a Zoom call to learn which information revealed by the Armorer was new to the fans. They also told her that they were establishing some of Season 3's groundwork and things that would appear later. They then explained how the Armorer fit into Season 3's story, which caused Swallow to better understand the Armorer's connection with Djarin. To prepare, the actress learned the Darksaber's lore by watching Star Wars animation. She said that working with director Bryce Dallas Howard felt like a dream because she asked her if there anything she wanted to try. Scenes on the Glavis Ringworld were filmed in the Volume set, which used StageCraft technology. While filming a long and grueling hammering sequence, Howard instructed Swallow on how to hammer via a microphone booming from the ether.
Swallow reprised her role as the Armorer in the third season of The Mandalorian. She learned specific details about the history of the Mandalorians and how the Armorer fits into it. Swallow said she wanted to learn what the Armorer personally lost during her backstory. She said she believes the Armorer has a "sixth sense," letting her see that Din Djarin has promise and will play an important part for the Mandalorian people. She felt that the Armorer was changed by Djarin because she never had such a personal relationship with someone like him and he challenged her in new ways. Swallow made sure she kept the Armorer shrouded in mystery. The episodes in the third season were shot out of order. For the episode "Chapter 17: The Apostate," Swallow and the other actors had to pretend to fight a large monster that was not there, which she found very strange. Swallow had a stunt double, but she did the stunts she could do and was always present during filming. She did not do any of the super technical moves she is not trained for and not insured to do. When the Armorer was swiped at by the creature and flipped, the armor was worn by Swallow's stunt double who was attached to wires. She landed on pads when the stunt was practiced. During shooting, the stunt double would slam into the wet sand when she flipped, and her helmet fell off during one shot.
