Hugo Stehler

Hugo Stehler (フーゴ・シュティラー) is a recruit of the Survey Corps. He appears in the light novel Attack on Titan: Before the Fall 3 and the manga series Attack on TItan: Before the Fall.

Appearance
Hugo is a tall young man with light to medium brown hair that is slicked back and scraggly at the ends. He has a long nose and small eyes that always appear to be closed. Hugo wears a white shirt underneath the traditional uniform of the Training Corps.

Personality
Hugo is, for the most part, a quiet and reserved individual; several of his friends even commented with surprise when Hugo spoke to Kuklo after the latter was able to escape detection by the Military Police. Like his friends and fellow squad mates, Hugo shows an interest in joining the Survey Corps but does not explicitly reveal his motivations for wanting to join.

Restoration of the Survey Corps arc
Hugo is with his friends as they perform a training exercise and come across Kuklo's unconscious and injured body. They take him to a cabin they found within a nearby forest. After the course of a week, Hugo hears from Rosa that the teen is awake, and they go see him. As the other recruits mention their reasons for wanting to join the Survey Corps, Hugo stays silent but nods in agreement with Felix's desire to see the world beyond the walls. Along with his friends, Hugo swears that he will do his best to prove to famed hero Jorge Pikale and his son Carlo, the current head of the Corps, that they are worthy of joining.

Roughly two weeks pass, and both Hugo and Felix inform Jorge that Kuklo wants to see him. They return to the cabin and find Kai, Rosa and Ivo being threatened by two members of the Military Police. After Jorge settles the issue, Hugo is amazed to see Kuklo hiding up in a tree and using his device to get down. Believing that Kuklo jumped up there, Hugo asks how he was able to escape being seen and hears how the device is used. Like Ivo, Hugo shows interest in being able to learn how to use the device.

Hugo is among those who volunteer to attend the special training regimen with his friends; he shows much improvement over the first month of training, and they are moved to the next phase of training that involves balancing. While many recruits fail the initial test (including Rosa, Kai and Felix), Hugo is able to pass the test along with Ivo and three others.
