Nile Dok

Commander Nile Dok (ナイル・ドーク師団長) is the chief of the Military Police.

Appearance
Nile is a man of average height and build. He has short, black hair that is cut shorter on the sides and back, and his eyes are dark in coloration. He also sports a very light mustache and goatee. He is always seen wearing the standard military uniform bearing the Military Police symbol, but also wears a bolo tie, similar to that of Dot Pixis and Erwin Smith.

Personality
Nile prides himself on being a very rational individual. Whenever he is faced with a tough choice, he weighs all possible options and chooses the one that makes the most sense to him. He wanted to have Eren Yeager executed, but was not blind to his usefulness like Pastor Nick was. He determined that the potential civil war within the walls was too great a cost, especially considering the Survey Corps could not guarantee anything about Eren. However, he relented his position when Levi brought up the fact that the Military Police would be ill equipped to deal with Eren in his Titan form. Nile is never totally committed to one way, and will change his opinion as the situation develops. A similar instance is when he questioned Erwin Smith due to him violating laws and command structure, but allowed his plan to go on since the Female Titan was already released and it would be very difficult to stop it without Erwin leading the Survey Corps.

However, with Nile's rational thinking comes a lack of empathy, or indifference. When told of Pastor Nick's murder and asked about why the Military Police wants Eren, he replied that he was just following orders and it is not his decision to make or question. Despite this, he violated orders and betrayed the King when he found their decision to doom half of humanity to be wrong. This shows that even though Nile strictly follows orders he does have a moral code. This code is apparently so strong that he was willing to risk his own life, since he certainly would have been executed for insubordination had the monarchy not been overthrown.

Nile has not been seen taking part in corruption within the Military Police. He does not seem to exercise a great deal of control over his branch of the military, since he admitted that the First Interior Squad is beyond his authority. He was also unaware of the First Interior Squad's anti-personnel maneuver gear, and had such little knowledge of the branch that he feared they may use the gear against himself. In his youth, he was good friends with Erwin and wanted to join the Survey Corps, but he gave up that aspiration to have a family with a woman named Marie. This decision sets him at odds with the idealistic Erwin who has no family due to the nature of his work, meanwhile, Nile believes his greatest achievement is his family.

History
Nile was a member of the same Trainees Squad as Erwin Smith, and the two were good friends. They agreed to join the Survey Corps together, but then Nile met a woman named Marie at the bar the group often frequented. Both men fell in love with her, but Nile ultimately chose to abandon his comrades to be with her. He enlisted in the Military Police Brigade, and started a family with Marie.

The Female Titan arc
Nile first appears as the leader of the Military Police during the trial of Eren Yeager. He advocates killing Eren due to the impending civil war, but he does analyse and weigh the different pros and cons of Eren before making his final decision. He recognizes that Eren's Titan powers had saved Trost District, but threaten the balance of power within human society. While mainly business and Wall Rose residents support Eren, most people of importance such as the clergy, view Eren as a danger. Thus, Nile concludes that to avoid civil war, Eren must not be allowed to live. Eren responds by calling him and his group a bunch of cowards, and Nile wants to have him killed; however, Levi interferes by beating Eren in front of everyone. Darius Zackly ultimately places Eren in the Survey Corps, and Nile is displeased that he lost the trial; however, he asks Erwin Smith how the Survey Corps intends to perform a mission to Wall Maria.

He later learns from Erwin Smith that Annie Leonhart is the Female Titan and that Wall Sina has been breached. Going by his suspicions, Nile orders Marlo, Hitch and the other members to assist the Survey Corps in capturing Annie.

Clash of the Titans arc
The meeting for Eren's judgement is put on hold when Erwin and Nile are ordered to attend a meeting to discuss the recent turn of events. However, the meeting is cut short when they learn that Wall Rose has been breached and Erwin rushes to investigate, while Nile sends members of the Military Police but does not go himself.

The Uprising arc
He meets with Erwin in the Capital, and it is revealed that they were once close friends during their time in the Trainee Corps. Erwin questions him about the Military Police Brigade's involvement in Pastor Nick's murder and learns that Nile doesn't know anything concerning the First Interior Squad's activities. He states that no laws exist that can restrain that group, and admits that he doesn't know if handing Eren over would resolve the current crisis.

Erwin inquires about Marie, Nile's wife, who is expecting their third child. Nile initially tells him not to change the subject, but the two men end up reminiscing about the past. He admits that he betrayed his comrades by abandoning them, but states he does not regret his decision because his family is his greatest achievement. Erwin admits to respecting his old friend, and the life he has managed to build for himself - something no one in the Survey Corps can ever have. Still, he offers Nile a vague warning about the future and advises him that protecting his position and protecting his family may not be the same thing. He makes several cryptic statements about their friendship, and reminds Nile that they can trust each other before exiting the carriage.

In parting, Erwin admits to having had feelings for Marie. Nile is startled by the sudden confession, but admits he already knew that and always thought Erwin insane for choosing the Titans over her. As the carriage pulls always, his expression darkens as he considers Erwin's many mysterious statements.

Following the battle in Stohess between the Survey Corps and the First Interior Squad of the Military Police, Nile requests that the media not inform the public of too much information concerning the First Interior Squad. As he leaves, Nile reflects on the First Interior Squad's anti-personnel maneuver gear, wondering if such weaponry will one day be used on him.

Nile next appears at the trial of Erwin Smith in the King's Throne Room. Erwin calls disbanding the Survey Corps a mistake by noting that they are a spear which eliminates threats, not a shield to hide behind. He goes on to say that if Wall Rose were breached their would be a civil war over the lack of resources in Wall Sina. When a government official asks if the Survey Corps could prevent this, Erwin responds that they would be proactive and remaining on the defence won't solve anything. The government official understands that despite torture Erwin still believes what he is saying, but notes that under Erwin's leadership Dimo Reeves was killed and recently Levi went on a killing spree of Military Police members. Given Levi's focus on action rather than diplomacy, the official declares that the Survey Corps does more harm than good. The monarchy asks Dot Pixis if he feels the same as Erwin to which he replies that he does not, but at the same time strongly believes that pushing humanity towards self-destruction is foolish. The monarchy tells Erwin he is finished and orders his captors to take him to the gallows. Nile appears worried at Erwin's fate, however just before he is taken away Anka Rheinberger, assistant to Pixis, bursts in. She loudly announces that Wall Rose has been breached by the Colossal Titan and Armored Titan, and that refugees are fleeing towards Wall Sina. Nile is in disbelief as he exchanges glances with Erwin and has a flashback. Erwin, chained to the wall after being tortured, is lectured by Nile. Nile told Erwin the irony that now he is lecturing Erwin, and the roles were reversed before. Nile informed Erwin that shortly he will be called to the King, who will no doubt announce his fate and disband the Survey Corps. Erwin asked Nile how his family was doing and where they were living. Nile replied that they are fine and living in Karanese District, although he did mention that he had not been home in a while. Erwin told Nile that he entrusted Pixis with a task, and that if the time comes, he would be watching Nile for his reaction. As Pixis tells the garrison to support the refugees Nile has his chance to make a decision. The official overrides Pixis' order and announces that all Wall Sina gates are to be sealed, lest a civil war break out. Nile shockingly states that this will doom half of humanity and the civil war may not happen. The monarchy are not taking any chances and talk amongst themselves that they need only wait a few days for those guys to acquire that power. As the Military Police present look to Nile for clarification about orders, he declares his intention to rebel against this command. A soldier asks if he is betraying the King and he responds that if this is their choice, he is.

At that very moment, Commander-in-Chief Darius Zackly appears with a group of soldiers while telling Nile that he can count him in as well. The monarchy question his presence here and he announces that what Anka said was a fabrication, Wall Rose has not been breached. As the official demands an explanation, Pixis provides one. He reveals how he devised this plan with Erwin Smith that if the monarchy was unfit to lead it would be proof that they need to be overthrown. However, he would have confessed the plot and served them totally had they chosen the right option. Pixis tells them that despite the power of Titans and their origin being unknown, that is preferable to following the monarchy. Anka reveals that the First Interior Squad have been disbanded while the official shouts that the people and nobility are loyal to the monarchy, so this coup will not work. Zackly announces that it is no longer up to them, and hands Erwin a report from the Belk Agency. It speaks of the testimony of one Flegel Reeves, who reveals that the First Interior Squad killed his father and framed the Survey Corps. The Report also unveils that the monarchy has been forcing the media to print propaganda, and that King Fritz is a puppet for a noble family who remains in seclusion. As the official shouts at the king for being a senile old man, Nile remarks that Erwin won his bet. Erwin tells Nile that despite that, humanity must now embark on a perilous road.
