Jean Kirschtein

Jean is a young man with spiky, gray hair shaved into an undercut style, with the shaved portion being black. He has small, intense brown eyes, and is said to have the same vicious look in them as Eren does. Jean is of average height and muscular build, and has a scowl similar to Eren's but is said to have a long face (a "horse face"). He is often seen wearing the typical uniform of the Survey Corps worn with an olive-gray button-up shirt. After overthrowing the government, his hair appears slightly longer than before.
His casual attire mostly consists of a white button-up shirt, dark pants, and a dark-brown vest. When concealing his identity, he also fashions a cloak and fedora.

Jean has a blunt personality. He holds no restraint when it comes to speaking his mind, even when he knows it would not be wise to do so or when it could spark conflict. Jean is also pragmatic: he has a strong aversion to exposing himself to dangerous situations, and has openly admitted his desire to join the Military Police is due to wanting an easy and safe life.
During his time as a trainee, Jean was extremely hot-headed, easily becoming frustrated and quick to resort to violence when pushed. Jean was also very cynical about defeating the Titans, believing that humanity has no chance against them. He openly mocked more idealistic individuals like Eren, and saw resisting the Titans as a hopeless cause.
Despite his shortcomings, Marco describes Jean as a natural leader, being able to understand others and assess situations well because of his flaws. Indeed, during the Battle of Trost District, Jean proves capable of leading his fellow soldiers when they are left confused and leaderless, and rallies Armin and Reiner in an attack on the Female Titan, knowing that not fighting her would endanger the rest of the Survey Corps.
Although he presents himself as self-centered, Jean places high value on the lives of others, and is ashamed and horrified when he must leave helpless allies behind to save himself and the remaining soldiers with him.

Jean is in love with Mikasa
