|I can't believe the fate of mankind rests in the hands of a coddled brat like you...|
|— Mitabi to Eren Jaeger|
Mitabi Jarnach (ミタビ・ヤルナッハ Mitabi Yarunahha?) was a team leader (班長 Hanchō?) and member of the Garrison in Trost District. He was one of the Garrison's top three elite soldiers who fought in the battle to retake Trost.
Mitabi had a short crop of brown hair and a very short beard. He wore the typical Garrison uniform with a green shirt underneath. He also had light-colored tannish eyes.
Mitabi was often seen around Ian Dietrich and Rico Brzenska, usually nervous or doubtful of the situation. Though initially terrified, he lured a group of Titans away from Eren Jaeger when he was carrying the boulder by yelling at them, hinting that he was not a total coward.
Mitabi and his team are among the soldiers assigned to protect Eren Jaeger on his mission to plug the breach in Trost's Wall created by the Colossal Titan. Once Eren loses control of his Titan form, Mitabi concludes that Eren is no different from the rest of the Pure Titans and he and Rico Brzenska decide to pull their teams out of the mission. Ian Dietrich refuses to give up, and orders Mitabi to take his team and defend Eren from the approaching Titans. Mitabi is appalled by Ian's decision, but Ian's argument that there is no other way to defeat the Titans without Eren is enough to convince him.
Eren eventually regains his senses and begins carrying a boulder to the Wall to plug its breach. In order to draw approaching Titans away from Eren, Mitabi and his men begin approaching the Titans on foot, hurling insults as they do so, to gain the Titans' attention. Mitabi is subsequently crushed by a Titan after getting distracted by the loss of one of his comrades.
When Hange decides to oppose Eren's plan to destroy the world beyond the Walls, Mitabi is one of the soldiers remembered while Hange tries to convince Jean and Mikasa that their fallen comrades would not support destroying the world.
