|— Flegel to the residents of abandoned buildings in Trost District|
Flegel Reeves (フレーゲル・リーブス Furēgeru Rībusu?) is the successor and son of Dimo Reeves. After his father's death, he assisted the Survey Corps in their take down of the Military Police Brigade and then overtook the position of CEO of the Reeves Company.
Flegel is a young man who possesses a fairly chubby build. He has light, short hair, freckles on his cheeks, and is usually seen wearing a regular black coat with a white shirt, as well as a pair of black pants.
Flegel seems to be a very proud person. He tells what he thinks and he does not shut his mouth for anyone. After his father's death, Flegel gained the motivation to fight against the Military Police. He seems to be a good leader and a brave person, which is shown when he vows to protect Trost.
Flegel is first shown sitting with his father, grouped with the Special Operations Squad. As a member of the Reeves company, Flegel is welcomed by Levi. In reply, he rudely says that Levi should be giving out tea if he really wanted to make a proper welcome, much to the shock of the others. Dimo shoves Flegel's head downwards, apologizing for his behavior. Nifa then proceeds to explain the plan to everyone.
Flegel is later shown inside a cave with Dimo, Eren, and Historia. He inquires as to why he and his father are going along with Levi's plan, saying that he would have beaten Levi up if he had raised his hand against Historia for any longer. After Dimo explains why he trusts Levi, Flegel calmly goes to outside to urinate. Unfortunately, Flegel is soon greeted by the sight of his father being killed by Kenny Ackerman, causing him to weep in horror while hiding behind a tree.
Flegel is later seen in the Trost District, hiding in an alley to avoid being detected by the Military Police. Without warning, he gets grabbed by Hange who takes him to a rooftop using her vertical maneuvering equipment. She introduces herself and asks Flegel to explain the incident behind his father's death. Flegel explains how his father was killed by a tall man in a black coat (referring to Kenny), and that Eren and Historia were taken away. In response, Hange tells him that the two of them can work together to expose the MP, but Flegel refuses in fear of his life. Regardless, Hange forcibly takes him along with her.Some time later, Flegel is shown fleeing from a group of three armed Military policemen. Eventually, he is cornered by them at a dead end, and is about to be executed. One of the policemen tearfully thanks Flegel, claiming that he would have been killed for letting him escape. Before he shoots, Flegel panics and asks him why his father was killed. Although the policeman is confused as to why Flegel is asking questions at a time like this, he explains how Dimo betrayed the MP, insulting him in the process. Hearing this, Flegel adamantly states that the policeman does not understand anything, and that he chooses to have faith in the people that his father believed in. The policeman, angered by Flegel's words, yells that he should be begging for mercy like a pig, to which Flegel replies by telling him to look above.
Hange and Moblit drop down from the building, knocking out the policemen and saving Flegel's life. Many of the citizens in Trost emerge from the building, one of them saying that they have heard the truth about Dimo Reeves' death and all of them will attest to it. The policeman shouts at the crowd, threatening them and claiming that the news of the incident will not spread for more than three days, but is stopped by Flegel, who sits on his head. He vows to protect Trost and announces himself as the new CEO of the Reeves Company, much to the happiness of the citizens.
On the night before the Survey Corps planned to set out on an expedition to reclaim Wall Maria, one of its squad leaders bought meat from Flegel's company as a way to reward the Corps' soldiers. Upon hearing what the meat was for, Flegel alerted the citizens of the Corps' plan to retake Wall Maria, resulting in them all gathering together in support of the Corps on the day of the expedition.
