Marlo Freudenberg (マルロ・フロイデンベルク Maruro Furoidenberuku?) is a member of the Military Police Brigade stationed in Stohess District until his branch change. He was a graduate of the 104th Cadet Corps, though he was not from the same division as Eren Jaeger.
Marlo is a young man whose hair was in the style of a bowl cut and usually wore his Military Police Brigade uniform. He is rarely seen without a stoic and serious expression on his face. He is also quite tall, especially when compared to his comrades. His hair is black and he had silver-colored eyes.
Marlo is a very righteous person. While most who join the Military Police Brigade do so because they want a safe position far from the danger of the Titans, Marlo did so because he wants "to uphold justice and do what's right". His goal is to rise to the top of the organization so he can stop the pilfering of taxes and misappropriation of land.
Marlo first appears as a member of the same Military Police Brigade unit as Annie Leonhart, and is assigned to guard the Scout Regiment convoy transporting Eren Jaeger as it passes through Stohess District. When he questions why they need to accompany the Scout Regiment through town, seeing an opportunity, his superior leaves Marlo in charge of the mission. Frustrated by the higher ranking officers' lack of morals and duties, he explains his motivation for joining the Military Police Brigade to the other recruits. He goes on a tirade about how the Military Police are no better than animals, and when he is in charge he will make them into what humans are supposed to be. This prompts Annie to speak her mind about what type of person he and the others are, implying that people like Marlo are rare and are not considered the majority. She only wants the weak people who are trapped in the flow to be considered human too, and suggests to him that it is not the people composing the system that are corrupt but rather the system itself.
While on duty, Marlo sees and confronts higher ranking officers that are illegally shipping omni-directional mobility gear to Black Market buyers. When he threatens to tell on them, they beat him up. Annie and Hitch intervene, and the officers decide to let him off the hook. Marlo, in anger, prepares to shoot them but when Annie says she will help him do it, he changes his mind. He asks if the idiot she knows would have done it, and she replies "maybe."
After the fight between Annie and Eren begins, Stohess is in utter ruin and Hitch can be seen on a roof top with Marlo and her other soldiers, questioning why there would be Titans fighting inside of Wall Sina.
After the aftermath of Eren and Annie's brawl in Stohess, Marlo and Hitch are seen looking at the rubble from the buildings and bodies scattered all over. Marlo wonders why they are being kept in the dark when they had just fought a Titan this far inside the Walls and Hitch replies that it is business as usual and notes that there is not an "official" reason why all these people died.
His exact abilities were not shown, but presumably he was skilled enough to gain entry into the Military Police Brigade.
- Hitch Dreyse - Marlo did not expect much of a serious attitude from Hitch, since she was usually someone who was carefree and lighthearted towards Marlo. She was extremely protective of Marlo, however, and showed that she did care about him deeply.
