Darius Zackly

Generalissimo Darius Zackly (ダリス・ザックレー総統) is the head of all three divisions of the Military: the Survey Corps, the Garrison, and the Military Police Brigade.

Appearance
Zackly has grey hair and a scruffy grey beard. Overall, he looks like a rather old individual. He is seen wearing overalls and glasses with a white shirt. In the anime, he is seen wearing a brown jacket with a red sash over it, on top of a white shirt that has a large red medallion fastened to the collar. He has a brown overcoat with epaulettes that is adorned with medals over his brown jacket.

Personality
As the head of the entire military, his priorities lie within what is the good/best for all of humanity. According to Armin, Zackly is among the people capable of abandoning their humanity to outdo the Titans as well as having the guts to also abandon things important to them in order to change something in the world, along with Erwin Smith, Ian Dietrich and Dot Pixis.

The Female Titan arc
Zackly first appears when Eren is put on trial. After hearing arguments from Nile Dok in favor of executing Eren and from Erwin Smith in favor of placing him under the command of the Survey Corps, Zackly rules in Erwin's favor. He allows Eren to join the Survey Corps, with the caveat that he will be brought before the court once more after the mission to Wall Maria.
