Nile Dok

Nile prided himself on being a very rational individual. Whenever he was faced with a tough choice, he weighed all possible options and chose the one that made the most sense to him. He wanted to have Eren Yeager executed, but was not blind to his usefulness like Minister 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 Ackerman brought up the fact that the Military Police would be ill-equipped to deal with Eren in his Titan form. Nile was never totally committed to one way, and would change his opinion as a situation developed. A similar instance was 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, Nile's rational thinking came with a lack of empathy, or indifference. When told of Nick's murder and asked about why the Military Police wants Eren, he replied that he was just following orders and it was 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 showed that even though Nile strictly followed orders, he did have a moral code. This code was 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 had not been seen taking part in the wide-spread corruption that exists within the Military Police. He did not seem to exercise a great deal of control over his branch of the military, since he admitted that the First Interior Squad was beyond his authority. He was also unaware of the First Interior Squad's anti-personnel vertical maneuvering equipment, and had such little knowledge of the branch that he feared they may use the equipment 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 set him at odds with the idealistic Erwin who had no family due to the nature of his work; meanwhile, Nile believed his greatest achievement is his family.

Human form
As a human, Nile was a lean man with well-defined cheek and jaw bones. He had thin black hair that was cut shorter on the sides but was relatively shaggy elsewhere. Nile's eyes were notably narrow and dark, with mild bags beneath them. He also sported a very light mustache and goatee. He was always seen wearing the standard military uniform bearing the Military Police symbol, paired with a bolo tie similar to that of his fellow military commanders.

Nile's combat prowess was never explicitly demonstrated. However, seeing how he managed to rank high enough in the cadet squads to gain entry into Military Police, it can be assumed that his combat skills are similar to his fellow cadet Erwin.
