Moblit Berner (モブリット・バーナー Moburitto Bānā?) is a veteran member of the Scout Regiment and the executive officer (分隊副長 Buntai Fukuchō?) of the Scout Regiment's Fourth Squad, under the command of Hange Zoë. He also serves as Hange's assistant and messenger.
Moblit has short smooth brown hair parted down the middle and light brown eyes. He is of average height and build, but often carries a worried expression due to his superior officer's wild and impulsive personality. Moblit wears the typical uniform of a member of the Scout Regiment with a green button up shirt underneath, but he is sometimes seen wearing black pants with a white button down. On missions, he wears the Scout Regiment's green cloak.
He comes across as an intelligent and responsible person, which may be the reason he is tasked to keep his overzealous and eccentric superior out of trouble. Much of the time, this leaves him in a state of near-panic, having to constantly remind Hange to be more careful or yanking her to safety. That he remains at her side constantly suggests he is a loyal person, regardless of the stress involved with being under her command.
Moblit is among the many surprised recruits present when Levi, Isabel Magnolia, and Furlan Church are introduced to the Scout Regiment as new recruits. Along with Hange, he watches Levi demonstrate his superior omni-directional mobility gear skills during training.
Moblit takes part in the 49th Exterior Scouting Mission in Wall Maria, in the year 850. During the expedition outside the Walls, he tries, but fails, to calm down Hange when her proposal to attempt to capture a Titan alive is rejected by Erwin Smith. Moblit then follows Hange and watches her as she leaves the tent and angrily confronts Oruo Bozad after he annoys her.
Moblit first appears as Hange Zoë's assistant, standing nearby as she attempts to establish communication with the captured Titans whom she named Sawney and Beane. He is immensely panicked by Hange's seemingly reckless attempts to get the two Titans to respond to her, repeatedly telling her to step back.
Some time later, Hange purposefully jabs Beane in the heart with a long pole in order to determine the Titan's reaction to pain, screaming while doing so. Moblit is worried by her reaction, to which she responds that seeing Beane in such pain is what is causing her to scream and be so upset. Later on, another attempt at establishing communication with Sawney nearly causes him to bite her head off, and Moblit drags her away in fear while exclaiming that she will most certainly die if she does not exercise caution. After being once again summoned to the grounds where the Titans were being kept, Hange is in disarray at the sight of their murder. As she screams, Moblit attempts to calm her down from the side lines.
Moblit takes part in the 57th exterior scouting mission. He is assigned to the soldiers lying in wait for the Female Titan and is among them after she has been captured. As Levi intimidates the Female and tells her of his plans to dismember her real body, the Female Titan lets out a deafeningly loud roar which causes Moblit and Hange to cover their ears as the Titan shrieks. After the roar, Moblit wonders aloud if it was a death rattle, and is surprised to see numerous Titans begin to swarm the area and attack the female. When they begin to devour her, Commander Erwin Smith orders all squads to engage the Titans and defend the Female to the death. Moblit fights relentlessly among his comrades but to no avail. The Commander, realizing that all is lost, orders his soldiers to pull back and return to Calaneth District.
The Scout Regiment again attempt to capture the Female Titan, this time in Stohess District where they believe she is hiding. With Armin Arlelt's help, they single out Annie Leonhart as their suspect. With their suspicions correct, Eren Jaeger successfully manages to incapacitate Annie during the raid on Stohess. Moblit stands nearby, grabbing Hange's shoulders in a state of panic as the surrounding soldiers attempt to extract Annie from the nape of her Titan. However, Annie's last resort to crystallize herself makes her impossible to extract information from. Shortly after, Moblit is among those instructed to move Annie to a safer place where she would be held until further notice.
When the soldiers notice that there is a Titan within the Wall, he frantically runs toward Hange, asking for her orders. After the Titan is successfully covered, Moblit is present as Hange questions Nick about the Titan. When Hange holds Nick over the edge of Wall, he attempts to stop her, only to be told to stay back. When Hange throws Nick back onto the Wall, Moblit approaches Hange and attempts to speak with her.
That evening, the Scout Regiment prepares to depart Stohess District to investigate the sighting of Titans in Wall Rose. Moblit catches Hange still working on her research when the Scouts are supposed to leave in five minutes and tries to get her to leave.
When the Scouts stop in Ehrmich District, he joins the soldiers Hange takes to Utgard Castle on a mission to retrieve Historia Reiss. After the rescue is complete, he withdraws to the top of Wall Rose along with the rest of the Scouts. Garrison soldiers meet up with them and report that they have not found any breach in the Wall. Concerned, Hange discusses with Moblit the possibility of alternative methods the Titans could have used to enter; digging, for example.
Their discussion is disrupted by the revelation that Reiner Braun and Bertholdt Hoover are the Armored and Colossal Titans and their ensuing transformation into their Titan forms. Moblit joins the Scouts in attacking the Colossal Titan, which does not initially appear to be a difficult opponent aside from its size, but then the Colossal emits a powerful burst of scalding steam that drives the Scouts back.
Hange leaves most of the the squads with her watching the Colossal Titan in case Bertholdt emerges and takes the rest, including Moblit, after the Armored Titan. They find Reiner busy fighting Eren, who has taken on his Titan form. Moblit watches the battle as Eren gradually gains an advantage over Reiner thanks to Mikasa and Hange's assistance. Before Eren can win however, Reiner roars, signaling Bertholdt to fall down from his position on the Wall. Moblit is among the soldiers badly burned from the explosion caused by the landing of the Colossal Titan.
Later that same day, Erwin arrives with reinforcements and the lifts necessary to move the horses over the Wall for a rescue mission, since Reiner and Bertholdt have successfully kidnapped Eren. By this time Moblit has recovered enough that he can stand and report to Erwin. Hange, too weak to get up, grabs Moblit's leg and asks him to get a map, which she uses to explain Reiner and Bertholdt's destination to the rescue party.
Moblit watches the rescuers leave and then notices Hange crawling away. She asks for a horse to go to the village where they found the Titan that could not walk. Seeing her condition, Moblit goes to investigate in her place and tells her to stay put.
He arrives with a few other Scouts in Ragako and observes that the village has been destroyed, but there is no blood, nor are there any bodies. If the villagers escaped, then the Titans were having a field day in a completely empty village, which he finds difficult to believe. He also notes that the horses are still in their stable and have not been taken.
One of the Scouts lets Moblit know he has found the Titan trapped inside of a house, and another Scout brings him a portrait of Conny Springer's parents. Moblit holds it up while looking at the Titan. It quivers and attempts to get up, causing him to drop the portrait in surprise. One of the Scouts draws his blades to kill it, but Moblit stops him. The Titan settles down again, still immobile. Moblit picks up the portrait, now holding it upside-down, and notices the resemblance between Conny's mother and the face of the Titan.
Following Hange's recovery from her injuries, Moblit resumes his duties as her assistant. During an experiment to test Eren's endurance while in his Titan form, Moblit is tasked with recording the tests. During the final experiment, Hange is forced to physically remove Eren from his Titan after he collapses, while Moblit makes a sketch of the boy's heavily disfigured face.
Soon after, Moblit receives word that Pastor Nick has been murdered, and immediately notifies Hange. The two visit Nick's room, but are barred entrance by two members of the Military Police, who claim that they will interfere with the crime scene. When Hange's protests prompt one of the guards to get physical with her, Moblit quickly separates the two, formally introducing himself and Hange as members of the Scout Regiment. After hearing the policeman's explanation of what happened to Nick, the two depart. As they leave, Hange tells Moblit that it was the policemen who killed Nick, not a burglar.
Moblit and Hange travel to Squad Levi's hideout to inform them of Nick's death. Once Hange has concluded her story, Nifa arrives with a message from Erwin, which prompts Levi to order everyone to evacuate. Once they are safely away, Levi reveals to them that the Scout Regiment has been ordered to hand over Eren and Historia, and that a freeze has been placed on all future scout activity. Nifa also reveals that the Military Police payed Erwin a visit shortly after the decree, and Hange decides that she and Moblit will go to attempt to aid the commander.
After visiting Erwin and informing him of Eren and Historia's kidnapping, as well as Hange's theory that Rod Reiss plans to consume Eren and steal his Titan powers, Moblit and Hange regroup with Levi's squad once again to torture Djel Sannes, who Levi has kidnapped. After learning from Sannes that the Reiss family is the true royal family, Moblit provides a sketch of Rod Reiss' face to Levi's squad to help them identify him.
Moblit and Hange travel to visit Erwin again, bringing news of the Reiss family's true status. Erwin gives them the results of his investigation into the Reiss family's property, but before they can continue, Erwin receives word that he has been accused of organizing a murder. As Erwin goes to face his accusers, he orders Moblit and Hange to leave the city immediately.
Moblit takes part in Hange's plan to use Flegel Reeves to trick members of the Military Police into admitting that the MPs murdered Dimo Reeves. After they have confessed, Hange and Moblit ambush and capture them.
Moblit is the executive officer of the Fourth Squad of the Scout Regiment and, being a senior member within this division, he has survived many expeditions alongside his immediate superior, Hange. He also possesses decent scientific abilities, serving as Hange's assistant during her experiments.
- Hange Zoë - Moblit acts as Hange's personal assistant and often supervises her throughout projects or helps her with certain tasks. He gets easily tired of Hange's bold gestures, sometimes reprimanding her for her hazardous actions.
- In an interview, Hajime Isayama mentioned that out of all the veterans of the Scout Regiment, Moblit drinks the most due to his "unfortunate" position.
